The most frequently asked questions about bariatric surgery and their answers
Under the current 2022 ASMBS/IFSO guideline, assessment for surgery is recommended from a BMI of 35 upwards, with no accompanying condition required; people with a BMI of 30–34.9 who have a metabolic disease such as type 2 diabetes may also be assessed. Rather than a fixed upper age limit, overall health and the benefit–risk balance are the deciding factors. Final eligibility is determined through individual clinical assessment.
Sleeve gastrectomy is less invasive, preserves intestinal absorption and carries a lower long-term vitamin-deficiency risk. For advanced type 2 diabetes, severe reflux or BMI 50+, gastric bypass / mini bypass delivers a stronger metabolic effect — we decide together based on your health profile, blood values and lifestyle.
With an experienced team and a fully equipped hospital, the sleeve gastrectomy complication rate is below 1% — comparable to a gallbladder operation. Possible risks include bleeding, infection and rarely a leak at the staple line; thorough pre-operative testing, coagulation profile and pulmonary assessment minimize these risks.
Following sleeve gastrectomy, loss of 60-70% of excess weight within the first 12-18 months is reported in the literature; following gastric bypass, 70-80%. An average loss of 10-15 kg in the first month is within the typical range. Surgery is a tool; long-term maintenance of outcomes depends on adherence to nutrition and lifestyle recommendations. Annual follow-up, dietitian assessment and revision options where indicated are part of the standard follow-up protocol.
Patients typically stay 3-4 days in hospital. You can return to a desk job in 7-10 days and to physically demanding work in 3-4 weeks. Full recovery takes 4-6 weeks; heavy sports, swimming and long travel are allowed after week 6.
We offer all-inclusive packages including a free online consultation, VIP airport transfers, companion accommodation, interpreter services and 1 year of free online follow-up. The average stay in Turkey is 7 days, and the total cost is 60-75% lower than in Europe or the USA. Reach us via WhatsApp or email for detailed package and pricing information.
