Highlights of Bariatric Care
What is Bariatric Surgery?
Bariatric surgery, also called weight-loss or metabolic surgery, changes the size of the stomach and, in some procedures, the way food passes through the digestive system.
It is not a cosmetic procedure or a quick solution. It is a medical treatment for obesity that works best when combined with lasting changes to food habits, physical activity and regular follow-up.
Who May Benefit from Bariatric Surgery?
Bariatric surgery may be considered when:
Obesity is affecting health or mobility
Diet, exercise or medicines have not produced sufficient long-term results
Weight-related conditions such as type 2 diabetes, high blood pressure or sleep apnoea are present
The patient understands and is ready for long-term lifestyle changes
Eligibility is not decided by body weight alone. The team considers BMI, overall health, previous weight-loss efforts and related medical conditions before recommending surgery.
Types of Bariatric Surgery
Sleeve gastrectomy
A large part of the stomach is removed, leaving a smaller tube-shaped stomach. This limits how much food can be eaten and may reduce hunger.
Gastric bypass
A small stomach pouch is created and connected to a lower part of the small intestine. This reduces food intake and changes how the body absorbs and responds to food.
Adjustable gastric band
A band is placed around the upper part of the stomach to create a smaller pouch. It can be adjusted according to the patient’s needs. Your surgeon will explain whether this option is appropriate.
Biliopancreatic diversion with duodenal switch
This procedure combines a sleeve gastrectomy with an intestinal bypass. It may be considered for selected patients with severe obesity or related metabolic conditions and requires close nutritional follow-up.
The right procedure differs for every patient. Your surgeon will explain the expected benefits, possible risks and lifestyle changes associated with each option.
Benefits of Bariatric Surgery
For suitable patients, bariatric surgery may support:
Significant and sustained weight loss
Better control of type 2 diabetes
Improvement in high blood pressure
Reduced symptoms of sleep apnoea
Improved movement and physical activity
Better management of other obesity-related conditions

Results vary between patients. Long-term success depends on following dietary advice, staying active and attending regular follow-up appointments.
