Metabolic surgery for type 2 diabetes: Tunisia guide
Type 2 diabetes and metabolic surgery in Tunisia: remission, criteria and follow-up

Type 2 diabetes and metabolic surgery in Tunisia: remission, criteria and follow-up

In short: Metabolic surgery, mainly the gastric bypass and the sleeve gastrectomy, is the most effective treatment known for putting type 2 diabetes into remission in people with obesity, but it is not a guaranteed cure. Remission means a normal long-term blood sugar (HbA1c below 6.5%) without diabetes medicines, and it is most likely when diabetes is recent, insulin is not yet needed and weight loss is good in the first year. In Switzerland, basic insurance covers bariatric surgery from a BMI above 35 under strict conditions, and Swiss guidelines allow metabolic surgery from a BMI of 30 for hard-to-control diabetes only in recognised reference centres. A US study published in October 2026, with up to 14 years of follow-up, found that 58% of operated patients achieved remission at some point, against 3% with medical treatment. Surgery in Tunisia is considerably less expensive than in Switzerland; the exact price is given in a free quote. This guide explains the criteria, the medicines, the blood sugar follow-up and what to organise in Switzerland.

What do the 2025-2026 studies and rules say?

The evidence that surgery helps type 2 diabetes has been strong for years. What is new is long-term data on who benefits most, and clearer Swiss rules on reimbursement of both surgery and weight-loss medicines.

What did the latest long-term study find?

On 20 October 2026, the journal Diabetes Care published an analysis of ARMMS-T2D, a group of four US randomised trials comparing metabolic surgery with intensive medical and lifestyle treatment in 262 people with type 2 diabetes and an average BMI of 36.4. Over a median of 11 years, and up to 14 years, 58% of the patients assigned to surgery achieved diabetes remission (HbA1c below 6.5% without glucose-lowering medicines) at some point, against 3% of those assigned to medical treatment. Remission was more likely in people with a shorter duration of diabetes, no insulin use, fewer diabetes medicines and greater weight loss at one year. Relapse after remission was more likely in people who had had diabetes longer and used more medicines before surgery.

Did earlier results from the same trials hold up?

Yes. In February 2024, JAMA published the main ARMMS-T2D results: after seven years, HbA1c had fallen by 1.6 percentage points from a baseline of 8.7% in the surgery group, against 0.2 points from 8.2% in the medical group. The benefit of surgery on blood sugar persisted over time, although some patients relapsed. These are American trials with gastric bypass, sleeve gastrectomy and gastric banding, but they are among the longest randomised data available.

What are the Swiss rules in 2026?

The edition of Annex 1 of the Swiss Health Care Benefits Ordinance (KLV/OPAS) dated 1 July 2026 confirms that basic insurance covers surgical treatment of obesity when the BMI is above 35 and two years of adequate weight-loss treatment have failed, with indication, surgery, quality control and follow-up according to the guidelines of the Swiss Society for the Study of Morbid Obesity and Metabolic Disorders (SMOB) of 1 July 2023. Those SMOB guidelines also define metabolic surgery for people with type 2 diabetes and a BMI between 30 and 35, under strict conditions explained below.

And weight-loss medicines?

Wegovy (semaglutide) has been reimbursed in Switzerland for obesity since March 2024 and Mounjaro (tirzepatide) since 1 January 2026, under strict conditions, according to a position paper by the Swiss Association of Dietitians (SVDE) and the Swiss Obesity Alliance (ALLOB) dated January 2026. The University Hospital Zurich summarises the conditions on its patient page: among other criteria, people who have had or are planning bariatric surgery are not eligible under the standard reimbursement for obesity. For type 2 diabetes, several medicines of the same family are reimbursed as diabetes treatments under their own conditions; your doctor will tell you which apply.

Why does surgery improve type 2 diabetes?

Is it just the weight loss?

No, and that is what surprised doctors first. After a gastric bypass, blood sugar often improves within days, before any significant weight loss. Medespoir’s obesity surgery guide (in French) describes this rapid effect as a sign of a hormonal mechanism distinct from simple restriction. Weight loss then adds a second, slower effect by reducing fat in the liver and muscles and improving the body’s sensitivity to insulin.

What happens in the gut?

When food reaches the lower small intestine faster, as after a bypass, the gut releases more of the hormones that stimulate insulin and reduce appetite, including GLP-1, the same hormone imitated by medicines such as semaglutide. The amount of food eaten falls sharply in the first weeks, which also lowers blood sugar. Changes in bile acids and gut bacteria probably contribute. After a sleeve gastrectomy, food also passes faster into the intestine and the hormone that drives hunger falls, which helps both weight and blood sugar.

Why does it work less well in some people?

Type 2 diabetes is caused by two problems: the body resists insulin, and the pancreas progressively loses its capacity to produce it. Surgery mainly improves the first. When diabetes has lasted many years and the pancreas has lost much of its function, often reflected by the need for insulin, remission is less likely, even though blood sugar usually still improves. This is why timing matters.

What does « remission » really mean?

Is remission the same as a cure?

No. An international consensus published in Diabetes Care in 2021 defines remission as an HbA1c below 6.5% measured at least three months after stopping all glucose-lowering medicines. The word « remission » was chosen deliberately: diabetes can return, especially if weight is regained or with age. People in remission still need regular blood tests and the usual checks of eyes, kidneys and feet.

What is HbA1c?

HbA1c, or glycated haemoglobin, reflects the average blood sugar over the past two to three months. It is the main measure used to diagnose diabetes, judge its control and define remission. Note that HbA1c can be less reliable in some situations, such as anaemia or after blood loss, both of which can occur after bariatric surgery; your doctor may then use other measurements.

What if I am not in remission after surgery?

Surgery can still be very worthwhile. Many people who do not reach full remission need fewer medicines, stop insulin or reduce the dose, and have better control, with lower blood pressure and cholesterol. The goal should be discussed honestly before surgery: remission is a possible outcome, better control is a likely one.

Can diabetes come back?

Yes. In the ARMMS-T2D analysis of October 2026, relapse after remission was more frequent in people who had had diabetes longer and used more medicines before surgery. Weight regain is another factor. This is why lifelong follow-up is part of metabolic surgery, not an option.

Factor More favourable for remission Less favourable
Duration of diabetes Recent diagnosis Many years
Treatment Tablets only, few medicines Insulin, several medicine classes
Insulin production Preserved (higher C-peptide) Reduced
Weight loss at one year Substantial Limited
Follow-up and lifestyle Regular, with activity and diet support Irregular follow-up, weight regain

Who is eligible? Swiss and international criteria

What are the Swiss criteria for bariatric surgery?

Under KLV Annex 1, basic insurance covers bariatric surgery when the BMI is above 35, two years of adequate weight-loss treatment have failed, and the operation is performed according to the SMOB guidelines, in a centre recognised by the SMOB or with the insurer’s special prior approval. Type 2 diabetes is listed among the obesity-related diseases that weigh in the assessment.

What is the Swiss rule for diabetes with a BMI between 30 and 35?

The SMOB guidelines of 1 July 2023 describe metabolic surgery for people with type 2 diabetes that is difficult to control and a BMI between 30 and 35. The conditions are strict: an HbA1c below 8% cannot be reached over at least 12 months despite optimal treatment by an endocrinologist and a qualified dietitian; the decision is taken by an interdisciplinary team including an endocrinologist; and the operation is performed only in a bariatric reference centre recognised by the SMOB. Surgery is not considered a first-line treatment. If you are in this group, ask your insurer and your endocrinologist about cover before taking any decision.

What do the international guidelines say?

The 2022 guidelines of the American Society for Metabolic and Bariatric Surgery (ASMBS) and the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) recommend metabolic and bariatric surgery from a BMI of 35 regardless of other diseases, and suggest considering it from a BMI of 30 in people with metabolic disease such as type 2 diabetes. They also recommend lower thresholds for people of Asian origin, in whom metabolic risk rises at a lower BMI. These guidelines are broader than Swiss reimbursement rules; they describe medical appropriateness, not who pays.

Is surgery suitable for type 1 diabetes?

Not as a treatment for diabetes. Type 1 diabetes and the slowly progressive autoimmune form sometimes called LADA are caused by the destruction of insulin-producing cells; surgery cannot restore them. People with type 1 diabetes and obesity are sometimes operated on for their weight, but in specialised centres and never with the aim of stopping insulin. If there is any doubt about your type of diabetes, tests for antibodies and C-peptide clarify it before surgery.

When is surgery not advisable?

The SMOB guidelines list contraindications that include an ongoing pregnancy, unstable coronary heart disease or a heart attack less than six months ago (assessed by a cardiologist or anaesthetist), severe kidney failure without dialysis, advanced liver cirrhosis, a pulmonary embolism or deep vein thrombosis in the past six months, uncontrolled cancer or cancer in remission for less than two years (unless an oncologist agrees), Crohn’s disease without the agreement of the treating gastroenterologist, severe mental illness with recurrent decompensations in the past two years, persistent substance abuse (especially alcohol, cannabis or opiates) without at least six months of documented abstinence and specialised follow-up, and an inability to understand or follow the post-operative requirements such as supplements and check-ups. Uncontrolled diabetes itself is not a contraindication but must be stabilised before the operation to reduce the risk of complications.

Is there an age limit?

Not a strict one. The SMOB guidelines ask that, for people over 65, surgical risks and remaining life expectancy be weighed carefully, and that they be operated on only in reference centres. For people with diabetes, the expected benefit also falls as the duration of diabetes increases, which is one more reason not to postpone the discussion indefinitely if surgery is being considered.

Bypass, sleeve or mini-bypass for diabetes?

All three improve type 2 diabetes. The choice depends on your diabetes, your weight, reflux, your eating habits and your ability to take supplements for life. For a broader comparison of all procedures, see our guide on choosing weight-loss surgery before going to Tunisia.

Why is the gastric bypass often recommended for diabetes?

Because its effect on type 2 diabetes is the best documented. Medespoir’s obesity guide states that long-standing type 2 diabetes is one of the situations that point towards a gastric bypass, along with severe reflux. The bypass requires lifelong supplementation and regular blood tests to prevent deficiencies. Medespoir describes the operation on its French page on the gastric bypass.

Is a sleeve enough?

For many people with recent diabetes, yes. The sleeve also improves blood sugar well, is technically simpler and requires less supplementation, but it can worsen or cause reflux. In people with long-standing diabetes or insulin treatment, many surgeons prefer a bypass, but the choice is individual. Medespoir’s page on the sleeve gastrectomy (in French) explains the technique.

And the mini-bypass?

The one-anastomosis gastric bypass, or mini-bypass, has a single connection instead of two. According to Medespoir’s guide, its results on weight and diabetes are close to those of the classic bypass, with a shorter operating time, but it carries a risk of bile reflux that requires careful assessment.

Procedure Effect on type 2 diabetes Effect on reflux Supplements
Gastric bypass Best documented Improves it Lifelong, non-negotiable
Sleeve gastrectomy Good Can worsen it Moderate, lifelong monitoring
Mini-bypass Close to the bypass Risk of bile reflux to assess Lifelong
Gastric band Weaker and less durable Variable Lighter

Table based on the comparison in Medespoir’s obesity surgery guide.

Preparing for surgery when you have diabetes

Which tests are needed?

A complete blood test including blood sugar, HbA1c, lipids, liver, kidney and thyroid function, as listed in Medespoir’s guide, plus tests your doctor considers useful for your diabetes: urine albumin for the kidneys, an eye examination, an ECG or cardiac assessment depending on your age and risk, and sometimes C-peptide. Many of these can be done by your GP or diabetologist in Switzerland and sent with your file.

Why is an eye examination important before surgery?

Because rapid improvement of blood sugar can temporarily worsen existing diabetic retinopathy, a phenomenon also seen with intensive medical treatment. If you have retinopathy, your ophthalmologist should know about the planned surgery and check your eyes again in the months afterwards.

Do I need to improve my HbA1c before the operation?

It is preferable. Very high blood sugar before surgery increases the risk of infection and poor healing. Your doctor may adjust your treatment in the weeks before. The pre-operative diet, often very low in calories and carbohydrates, also lowers blood sugar quickly, which means medicines usually have to be reduced at that stage to avoid hypoglycaemia.

What about sleep apnoea, blood pressure and the heart?

People with type 2 diabetes and obesity often also have sleep apnoea, high blood pressure and an increased cardiovascular risk. These must be known before anaesthesia. If you use a CPAP machine, take it with you. Declare any history of heart disease, stroke or kidney disease.

Should I stop smoking?

Yes. Smoking increases the risk of ulcers at the connections made during a bypass, chest infections and blood clots, and it worsens the vascular complications of diabetes. Stopping well before surgery, and for good, is one of the most useful things you can do.

Diabetes medicines before and after the operation

This section describes general principles. Your diabetologist, your surgeon and the anaesthetist decide on your actual plan, which you should receive in writing.

Which medicines are usually paused before surgery?

  • SGLT2 inhibitors (such as empagliflozin, dapagliflozin or canagliflozin): usually stopped a few days before surgery, because of the risk of a dangerous form of ketoacidosis with near-normal blood sugar, particularly during fasting and very low-calorie diets. US product information recommends stopping most of them at least three days before planned surgery.
  • GLP-1 receptor agonists and tirzepatide: they slow stomach emptying, which matters for anaesthesia. The team decides whether to pause them and for how long, and may ask for a liquid diet the day before.
  • Sulfonylureas (such as gliclazide): often reduced or stopped around surgery because they can cause hypoglycaemia when food intake falls.
  • Insulin: doses are usually reduced during the pre-operative diet and on the day of surgery, according to a written plan.
  • Metformin: often stopped on the day of surgery and resumed afterwards according to kidney function and food intake.

What happens to my treatment right after surgery?

Because food intake drops sharply and the gut hormones change, many people need much less medicine immediately. Insulin doses are often reduced substantially or stopped, and medicines that can cause hypoglycaemia are generally avoided. Metformin is frequently the medicine kept longest while blood sugar is monitored. The aim is to avoid both hypoglycaemia and high blood sugar during the first weeks.

Do tablets work the same way after a bypass?

Not always. The absorption of some medicines changes after a bypass. Extended-release and large tablets may be absorbed differently, and some medicines are better taken crushed or in liquid form during the first weeks. Ask your pharmacist or doctor to review every medicine you take, not only those for diabetes.

Who adjusts my treatment once I am home?

Your GP or diabetologist in Switzerland. Before you leave Tunisia, you should receive the operative report, the discharge letter and a written medication plan. Make an appointment with your doctor for the first or second week after your return, and bring your blood sugar readings.

Blood sugar follow-up after surgery

How often should I check my blood sugar?

In the first weeks, often several times a day if you still take insulin or medicines that can cause hypoglycaemia, and as advised by your doctor if you do not. A continuous glucose monitor can be useful in some people, especially if hypoglycaemia is suspected. Write down your readings and any symptoms.

When will HbA1c be measured?

Usually about three months after surgery, then every three to six months during the first years, and at least once a year after that. The SMOB guidelines require recognised Swiss centres to record HbA1c, fasting blood sugar, medicines and remission according to the American Diabetes Association criteria for patients operated on for diabetes with a BMI of 30 to 35, and to follow all patients for life.

How often are follow-up visits planned?

For a gastric bypass, the SMOB guidelines plan follow-up visits after 1, 3, 6, 9, 12, 18 and 24 months, then every year or as needed. For people with diabetes, these visits are the natural moment to review blood sugar readings, HbA1c and medicines, alongside weight and nutrition. If you were operated on abroad, ask your Swiss doctor to follow a similar calendar.

What should I eat to keep blood sugar stable?

The principles are the same as for any bariatric patient, with extra attention to sugars:

  • Eat protein first at each meal, then vegetables, then starchy foods in small quantities.
  • Avoid sweet drinks, fruit juices, sweets and white bread on their own: they raise blood sugar quickly and are the main trigger of dumping and late hypoglycaemia.
  • Prefer slowly absorbed carbohydrates such as pulses, wholegrain products and vegetables.
  • Eat small meals, slowly, and drink between meals rather than with them.
  • Keep a source of fast sugar with you if you still take insulin or a sulfonylurea, and know how to treat a hypoglycaemia.

A dietitian in Switzerland can adapt these rules to your treatment. Dietary advice by a recognised dietitian on medical prescription is covered by basic insurance in defined situations, including diabetes and obesity; ask your doctor.

What should I do when I am ill?

During a gastroenteritis, a fever or any illness that stops you eating or drinking, blood sugar can swing in both directions and dehydration comes quickly after bariatric surgery. Ask your doctor in advance for « sick day rules »: which medicines to pause (often metformin and SGLT2 inhibitors), how often to check your blood sugar, and when to seek help. Vomiting that prevents you from drinking for more than a few hours requires medical attention.

What other checks continue?

All the usual diabetes checks: yearly eye examination, kidney tests, foot checks, blood pressure and cholesterol. On top of these come the bariatric checks: vitamins, iron, calcium, vitamin D, vitamin B12, folate and protein status, according to the operation performed. Our guide on life after bariatric surgery and follow-up in Switzerland details the supplementation and the follow-up calendar.

When What to check Who
First days after return Blood sugar readings, medicines, wound, hydration GP or diabetologist
About 3 months HbA1c, kidney function, vitamins and iron GP or diabetologist
Every 3 to 6 months in the first years HbA1c, weight, medicines, deficiencies GP, diabetologist, dietitian
Every year, for life HbA1c, eyes, kidneys, feet, vitamins, bone health GP, specialists

Specific risks: hypoglycaemia, relapse, eyes and kidneys

Can surgery cause low blood sugar?

Yes, in two ways. In the first weeks, hypoglycaemia is usually caused by diabetes medicines that have not been reduced enough. Later, often one to three years after a gastric bypass, some people develop post-bariatric hypoglycaemia: blood sugar drops one to three hours after a meal rich in fast sugars, because the gut releases too much insulin-stimulating hormone. Symptoms include sweating, trembling, palpitations, confusion and, in severe cases, loss of consciousness. Report them to your doctor; the first treatment is usually a change in diet.

What is dumping syndrome?

Early dumping occurs shortly after eating sugary or large meals: cramps, bloating, diarrhoea, a feeling of faintness and a racing heart, caused by food arriving too fast in the intestine. Late dumping is the hypoglycaemia described above. Eating small meals, avoiding fast sugars and separating drinks from meals reduce both.

Should I drive if I have hypoglycaemia?

Not during or soon after an episode. If you have repeated hypoglycaemia after surgery, discuss driving safety with your doctor, especially if you drive for work.

What about alcohol?

After a bypass or a sleeve, alcohol is absorbed faster and reaches higher blood levels, and it can cause hypoglycaemia. Long-term studies have also found a higher risk of alcohol problems after bypass. Keep alcohol limited and never drink on an empty stomach.

Does surgery protect the kidneys and the heart?

Observational studies have linked metabolic surgery to fewer cardiovascular events and slower kidney decline in people with diabetes and obesity, but these are not randomised trials, and existing damage does not disappear. Keep up blood pressure and cholesterol treatment as advised, even if your diabetes goes into remission.

Surgery or GLP-1 medicines?

Are injections like semaglutide or tirzepatide an alternative?

For many people they are, and the choice is no longer « surgery or nothing ». These medicines lower blood sugar and weight substantially. They must usually be taken long-term, because weight and blood sugar tend to rise again when they are stopped. Surgery produces larger and more durable weight loss on average and a higher chance of diabetes remission, but it is an irreversible operation with surgical risks and lifelong supplementation.

Can both be combined?

Yes, medically. Some people use a GLP-1 medicine before surgery to reduce weight and improve blood sugar, and others after surgery if diabetes relapses or weight returns. In Switzerland, the standard reimbursement conditions for obesity exclude people who have had or are planning bariatric surgery, so after surgery the cost may fall on you unless the medicine is prescribed and reimbursed for diabetes under its own conditions, or your insurer agrees otherwise.

How do I decide?

With your diabetologist and an experienced bariatric team, looking at your BMI, the duration and treatment of your diabetes, your other illnesses, your preferences and your ability to follow lifelong care. A person with recent diabetes and a BMI of 42 has a very different decision to make from a person with 15 years of insulin-treated diabetes and a BMI of 32.

Questions to ask before deciding

What should I ask my diabetologist?

  • How much insulin does my pancreas still produce, and what does that mean for my chance of remission?
  • Have all medical options been tried, and which ones are still open to me?
  • Do I have retinopathy, kidney disease or nerve damage that needs checking before surgery?
  • Will you follow me after an operation, including if it is done abroad?

What should I ask the surgical team?

  • Which operation do you recommend for my diabetes, my weight and my reflux, and why?
  • How will my diabetes medicines be adjusted before, during and after the operation, and will I receive this plan in writing?
  • How is blood sugar monitored during the hospital stay and at the hotel?
  • Which supplements will I need for life, and which blood tests?
  • Who do I contact if I have hypoglycaemia or vomiting after returning to Switzerland?

What about women who want children?

Fertility often improves after weight loss, sometimes quickly, including in women with polycystic ovary syndrome. Pregnancy is generally advised against during the period of rapid weight loss, usually the first 12 to 18 months, and the absorption of oral contraceptives can be less reliable after a bypass. Discuss contraception before surgery. A later pregnancy needs close follow-up of nutrition and blood sugar; Medespoir has a French page on pregnancy after a sleeve.

Four typical situations

These composite examples are not real patients. They illustrate how the decision changes with the profile.

Stefan, 46, Winterthur: recent diabetes, BMI 41

Stefan was diagnosed two years ago and takes metformin. He meets the Swiss criteria for cover. He hesitates between surgery in a Swiss centre with reimbursement and a self-funded operation abroad. His profile is very favourable for remission. His diabetologist explains that in his case basic insurance can pay in Switzerland if the conditions are met, which is a strong argument for that route.

Fatima, 54, Geneva: insulin for eight years, BMI 37

Fatima’s diabetes is poorly controlled despite insulin. Remission is less likely, but a gastric bypass could reduce her insulin needs substantially. She prepares her eye examination and kidney tests in Switzerland, and the team plans a careful reduction of her insulin before and after surgery.

Paul, 51, Bern: BMI 33, HbA1c above 8%

Paul’s diabetes has been hard to control for over a year despite treatment by an endocrinologist and a dietitian. Under the Swiss guidelines, metabolic surgery is possible only in a recognised reference centre. His endocrinologist first proposes optimising medicines, including a GLP-1 treatment, then reconsidering surgery if control remains poor.

Laura, 39, Lausanne: diabetes in remission after a sleeve, now rising again

Laura was operated on six years ago. Her HbA1c has risen above 6.5% with some weight regain. She returns to her GP, resumes regular blood tests and works with a dietitian. Her doctor discusses medical treatment. Relapse is not a failure; it is a reason for follow-up, which is why it must never stop.

Metabolic surgery in Tunisia with follow-up in Switzerland

Why do some Swiss residents with diabetes consider Tunisia?

Medespoir’s obesity guide describes the situations: people whose BMI does not reach the Swiss reimbursement criteria despite real health problems, people whose request was refused on a formal criterion, and people who find the Swiss pathway too long while their diabetes progresses. The guide is also clear that going abroad means giving up Swiss reimbursement: basic insurance does not pay for planned treatment abroad. The operation in Tunisia is considerably less expensive than in Switzerland; the exact price is given in your free quote.

Should I go abroad if I meet the Swiss criteria?

Think carefully. If you are eligible for reimbursement in Switzerland, the financial argument for going abroad largely disappears, and having surgery near your follow-up team is an advantage. Tunisia makes more sense for people who are not eligible or who have made an informed choice to pay privately.

How is the stay organised?

Medespoir’s stay page indicates that the same organisation applies to obesity surgery as to other operations: transfers, hotel with a companion, care and remote follow-up. The length of the stay is given in your quote. For a person with diabetes, plan time for blood sugar checks and medication adjustments before flying home.

What should my file contain?

  • Height, weight and weight history, including previous diets and medicines.
  • Recent blood tests: HbA1c, fasting glucose, kidney and liver function, lipids, thyroid.
  • The complete list of your medicines with doses, including insulin and injections.
  • Any diabetes complications: eyes, kidneys, nerves, heart.
  • Reflux symptoms and any previous gastroscopy.
  • The name of your GP or diabetologist in Switzerland who will follow you.

Who follows me after the return?

Medespoir provides remote follow-up after your return. Your diabetes and your bariatric follow-up continue with your GP or diabetologist and a dietitian in Switzerland. Talk to your doctor before the operation so that they agree to follow you. Care received in Switzerland is paid by you or your insurer according to the usual rules.

What about language?

In Tunisia, consultations and medical documents are in French. Ask for the discharge letter and medication plan in a form your Swiss doctor can read, translated if necessary, and consider travelling with a French-speaking companion.

Is metabolic surgery available in Turkey through Medespoir?

In Turkey, Medespoir confirms hair transplants. For bariatric or metabolic surgery, your quote states whether it is possible and where. Both destinations remain considerably less expensive than Switzerland.

Frequently asked questions

Can bariatric surgery cure type 2 diabetes?

It can put it into remission, often for years, but doctors speak of remission rather than cure because it can return.

How quickly does blood sugar improve after a bypass?

Often within days, before significant weight loss, because of hormonal changes in the gut.

Will I be able to stop insulin?

Many people reduce or stop insulin, but those with long-standing insulin-treated diabetes are less likely to stop all treatment.

Is a BMI of 32 enough for surgery in Switzerland?

Only for hard-to-control type 2 diabetes, under the strict SMOB conditions and in a recognised reference centre. Ask your insurer about cover.

Which operation is best for diabetes?

The gastric bypass is the best documented, but a sleeve or mini-bypass can also be suitable. The choice is individual.

Should I stop my diabetes medicines before surgery?

Some must be paused or reduced, especially SGLT2 inhibitors, sulfonylureas and insulin, but only according to your doctors’ written plan.

What is HbA1c remission?

An HbA1c below 6.5% at least three months after stopping all glucose-lowering medicines.

Does Swiss basic insurance pay for metabolic surgery in Tunisia?

No. Basic insurance does not cover planned treatment abroad.

Do I still need eye checks if my diabetes is in remission?

Yes. Eye, kidney and foot checks continue, because existing damage does not disappear and diabetes can return.
