What Is Bariatric Surgery?
Bariatric surgery — from the Greek baros (weight) and iatrikos (medicine) — is the branch of surgery that treats severe obesity and its associated metabolic conditions. Unlike cosmetic surgery, bariatric surgery is a medically indicated intervention for a chronic disease, supported by decades of clinical evidence and endorsed by every major medical organisation worldwide.
The first bariatric procedures were performed in the 1950s. The laparoscopic revolution of the 1990s transformed the field, reducing complication rates and recovery times dramatically. Today, over 600,000 bariatric procedures are performed annually worldwide, and the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) recognises bariatric surgery as the single most effective long-term treatment for severe obesity.
A 2022 meta-analysis published in The Lancet confirmed that bariatric surgery produces significantly greater and more sustained weight loss than any non-surgical intervention — including intensive lifestyle programmes, pharmacotherapy, and the newest GLP-1 receptor agonists. Surgery also delivers superior rates of Type 2 diabetes remission, cardiovascular risk reduction, and overall mortality improvement.
At MedProper Istanbul, we perform the full range of bariatric procedures in a JCI-accredited hospital, with IFSO-member surgeons and all-inclusive packages starting from £1,275.
The Science Behind Bariatric Surgery
Bariatric surgery is not simply about making the stomach smaller. Modern research has revealed a complex interplay of hormonal, neurological, and metabolic changes that explain why surgery succeeds where diets fail.
Why Diets Fail Long-Term
When you lose weight through calorie restriction, your body responds with a coordinated counter-attack known as metabolic adaptation. Resting metabolic rate decreases, hunger hormones (ghrelin) increase, satiety hormones (leptin, GLP-1, PYY) decrease, and your brain's reward system intensifies cravings for high-calorie foods. This "set point" defence mechanism means that 80-95% of patients who lose weight through diet alone regain it within five years.

Restriction: Reducing stomach volume from approximately 1 litre to 100-150 ml (sleeve) or 30 ml (bypass) physically limits food intake.
Hormonal restructuring: Removing or bypassing the stomach fundus reduces ghrelin (the hunger hormone) by 60-70%. Simultaneously, GLP-1 and PYY (satiety hormones) increase significantly, particularly after bypass procedures.
Bile acid changes: Bariatric surgery alters bile acid signalling, which independently improves insulin sensitivity and glucose metabolism — explaining why diabetes remission often occurs within days of surgery, before significant weight loss.
Gut microbiome remodelling: Surgery shifts the composition of intestinal bacteria toward profiles associated with leanness and improved metabolic health.
These mechanisms explain why bariatric surgery produces durable weight loss maintained at 10+ years, while non-surgical interventions almost universally fail to maintain results beyond 2-3 years.
Bariatric Procedures at MedProper Istanbul
Sleeve Gastrectomy (Gastric Sleeve)
The most commonly performed bariatric operation worldwide, representing approximately 55% of all procedures. The surgeon removes 75-80% of the stomach laparoscopically through 4-5 small incisions, leaving a narrow tube-shaped sleeve with a capacity of 100-150 ml.
Duration: 45-75 minutes under general anaesthesia
Hospital stay: 2-4 nights
Expected weight loss: 60-70% of excess weight in 12-18 months
MedProper price: from £1,925 / €2,250 all-inclusive
Best for: BMI 35-45 without severe gastroesophageal reflux.
Roux-en-Y Gastric Bypass
The gold standard for metabolic surgery. A small stomach pouch (approximately 30 ml) is created and connected directly to the jejunum, bypassing the majority of the stomach and the duodenum. The dual mechanism — restriction plus controlled malabsorption — produces the highest rates of Type 2 diabetes remission among all bariatric procedures.
Duration: 90-150 minutes
Hospital stay: 3-5 nights
Expected weight loss: 65-75% of excess weight in 12-18 months
Type 2 diabetes remission: 80%+ (the highest of any bariatric procedure)
GORD resolution: 90%+
MedProper price: from £2,695 / €3,150 all-inclusive
Best for: BMI over 45, poorly controlled Type 2 diabetes, or chronic acid reflux.
Mini Gastric Bypass (One-Anastomosis Gastric Bypass)
A simplified version of Roux-en-Y with a single intestinal connection rather than two. Creates a longer, tubular stomach pouch connected to a loop of small intestine approximately 200 cm from the ligament of Treitz. Now representing approximately 30% of all bypass procedures globally.
Duration: 60-90 minutes
Hospital stay: 3-4 nights
Expected weight loss: 65-75% of excess weight
MedProper price: from £2,695 / €3,150 all-inclusive
Best for: BMI 40+ or revision patients seeking bypass with shorter surgical time.
Intragastric Balloon
A non-surgical option. A silicone balloon is placed endoscopically (through the mouth, no incisions) into the stomach under light sedation and filled with saline. The balloon occupies space and creates early satiety. Placed for 6-12 months, then removed endoscopically.
Duration: 15-20 minutes under light sedation
Hospital stay: day case (no overnight stay required)
Expected weight loss: 10-15% of total body weight over 6 months
Fully reversible: yes
MedProper price: from £1,275 / €1,490 all-inclusive
Best for: BMI 27-35. Patients who prefer a non-surgical, fully reversible option.
Revisional Bariatric Surgery
Published data in Surgery for Obesity and Related Diseases (SOARD) indicates that 15-25% of bariatric patients require a revisional procedure within ten years. Common reasons include insufficient initial weight loss, weight regain after initial success, sleeve dilation, or chronic GORD following sleeve gastrectomy.
MedProper offers sleeve-to-bypass conversion and re-sleeve procedures, performed by bariatric surgeons with extensive revision experience.
MedProper price: from £2,520 / €2,950 all-inclusive

Clinical Outcomes and Evidence
Bariatric surgery is one of the most thoroughly studied surgical interventions in medicine. Key evidence:
Weight Loss

Gastric bypass: 65-75% excess weight loss at 12-18 months; 55-60% maintained at 10 years
Gastric balloon: 10-15% total body weight loss over 6 months

Mortality
A 2024 meta-analysis in The Lancet demonstrated that bariatric surgery reduces all-cause mortality by 50-70% in patients with severe obesity over a 10-year follow-up period. The survival benefit is particularly pronounced for patients with Type 2 diabetes and cardiovascular risk factors.
Fertility
Bariatric surgery significantly improves fertility in women with polycystic ovary syndrome (PCOS). Studies show normalisation of menstrual cycles in 70-80% of patients and increased natural conception rates.
