Results and limits
Weight loss can be substantial but is never guaranteed. Partial weight regain remains possible, and reflux may develop or worsen.

Bariatric surgery · Tunis
Four options explained clearly so you can understand how they work, their constraints, required follow-up and risks — without promises of results.
General information only. Every indication requires multidisciplinary assessment; surgical procedures require lasting medical and nutritional follow-up.
01 · Sleeve gastrectomy
A sleeve gastrectomy permanently removes a large part of the stomach, leaving a narrow tube. It limits portions and changes hunger signalling.
Weight loss can be substantial but is never guaranteed. Partial weight regain remains possible, and reflux may develop or worsen.
A liquid-to-solid staged diet, very small portions, adapted activity, supplements and regular blood tests are required. Medical and nutritional follow-up is lifelong.
Leak, bleeding, blood clots, infection, narrowing, reflux, nutritional deficiencies, gallstones and further surgery are possible.
02 · Gastric balloon
The balloon is usually placed in the stomach endoscopically, without an incision. It occupies space and may help reduce portions for a defined period.
Weight loss varies and is usually more modest than after surgery. Without lasting habit changes and dietary support, weight regain after removal is common.
Nausea, vomiting and cramps are common during the first days. A staged diet plus regular medical and dietary follow-up are essential during treatment and after removal.
Intolerance, dehydration, reflux, ulcer, deflation and migration causing obstruction, pancreatitis or difficult removal can occur.
03 · Gastric bypass
A bypass creates a small stomach pouch connected further down the intestine. It affects portions, absorption and metabolism.
Weight loss can be substantial and diabetes or reflux may improve, without any guarantee. Partial weight regain remains possible.
A very gradual diet, small portions, and lifelong vitamins and minerals are required. Very sugary or fatty food can trigger dumping syndrome with faintness, sweating and diarrhoea.
Leak, bleeding, clots, internal hernia, obstruction, ulcer, narrowing, severe deficiencies, hypoglycaemia and further surgery are possible.
04 · Gastric band
An adjustable band is placed around the upper stomach and connected to a port under the skin. It requires repeated adjustments.
Average weight loss is lower and less durable than with other techniques. Band removal is commonly followed by weight regain.
A staged diet, precise eating habits, adjustments over months or years, and lifelong medical, laboratory and dietary follow-up are required.
Band slippage, pouch or oesophageal dilation, erosion into the stomach, port problems, reflux, intolerance and repeat surgery are common long-term concerns.
