Bariatric & Metabolic Surgery

Bariatric surgery includes operations on the stomach and small intestine that help people with severe obesity lose weight, and may improve related conditions such as type 2 diabetes. Dr. Naser Dib's documented bariatric procedures are sleeve gastrectomy, gastric bypass and endoscopic intragastric balloon placement. His 2014 PhD research examined the effects of bariatric surgery in an experimental model.

Who may be considered for bariatric surgery?

Eligibility is assessed against current clinical guidelines, which consider body mass index (BMI), obesity-related health conditions and previous weight-loss attempts. Assessment usually involves several specialists, and the decision is made together with the patient.

Long-term commitment

Bariatric surgery is a tool, not a cure on its own. Lasting results depend on changes in eating and activity, vitamin supplementation and regular follow-up, often for life.

Related procedures

General information about procedures listed in Dr. Naser Dib's CV. Suitability is always decided individually.

Sleeve gastrectomy

What it is: A bariatric operation, usually performed laparoscopically, in which roughly three quarters of the stomach is removed, leaving a narrow, tube-shaped stomach. It reduces stomach capacity and affects hunger-related hormones. It cannot be reversed.
Common reasons: Severe obesity, assessed against current clinical guidelines that consider body mass index (BMI), obesity-related conditions and previous weight-loss attempts.
Before surgery: Assessment by a multidisciplinary team (for example surgeon, dietitian, psychologist and physician), often a gastroscopy, and sometimes a pre-operative diet.
How it is performed: Through small incisions, the stomach is divided with a surgical stapler along its length and the larger part is removed.
Recovery: Diet progresses in stages from liquids to solid food over several weeks. Lifelong vitamin supplements, healthy eating and regular follow-up are needed.
Possible risks: Leakage from the staple line, bleeding, narrowing of the stomach, new or worsening heartburn (reflux), nutritional deficiencies, weight regain and risks of anaesthesia.
Documented experience: Listed in Dr. Naser Dib's CV and professional profile; he co-authored a 2011 paper on the efficacy and safety of laparoscopic sleeve gastrectomy.

Gastric bypass

What it is: A bariatric operation in which a small stomach pouch is created and connected directly to the small intestine, so that food bypasses most of the stomach and the first part of the small intestine.
Common reasons: Severe obesity assessed against current guidelines. The choice between bypass and other operations depends on individual factors such as reflux, diabetes and eating patterns.
Before surgery: Multidisciplinary assessment, education about diet after surgery and, where needed, optimisation of other health conditions.
How it is performed: Usually performed laparoscopically: the stomach pouch is created with staplers and joined to a loop of small intestine.
Recovery: Staged diet over several weeks. Lifelong supplements (for example iron, vitamin B12, calcium and vitamin D) and long-term follow-up are required.
Possible risks: Leakage, bleeding, internal hernia and bowel obstruction, ulcers at the join, dumping syndrome, nutritional deficiencies and risks of anaesthesia.
Documented experience: Listed in Dr. Naser Dib's CV and professional profile among his bariatric procedures.

Endoscopic intragastric balloon

What it is: A soft balloon placed in the stomach through the mouth during an endoscopy, without incisions, and filled to take up space in the stomach. It is temporary and is removed after a period set by the balloon type, commonly around six months.
Common reasons: Overweight or obesity in selected people who are not candidates for, or do not wish to have, bariatric surgery, or as a step before surgery. It works alongside diet and lifestyle changes.
Before surgery: Medical and dietary assessment and fasting before the endoscopy.
How it is performed: During a gastroscopy under sedation, the balloon is inserted and filled with fluid or air, depending on the device.
Recovery: Nausea, vomiting and cramps are common in the first days. Weight may be regained after removal if eating habits do not change.
Possible risks: Nausea and vomiting, abdominal pain, reflux, stomach ulcer, deflation or movement of the balloon with rare bowel obstruction, and intolerance requiring early removal.
Documented experience: “Endoscopic balloon implementation” is listed in Dr. Naser Dib's CV. Certificate records include a 2009 intragastric balloon workshop and a 2013 trainer certificate for an intragastric air-balloon workshop.
