What is bariatric surgery?
Bariatric surgery reduces the size of the stomach and, in some procedures, changes how food passes through the digestive system. This helps you feel full sooner and can improve conditions such as type 2 diabetes, high blood pressure and sleep apnoea.
Surgery is a tool, not a cure: long-term success depends on lasting changes to diet and activity, and on regular follow-up.
Who is bariatric surgery suitable for?
Bariatric surgery may be considered if you:
- Have a high BMI, generally 35–40 or above, or lower with obesity-related conditions
- Have tried other ways to lose weight without lasting success
- Have obesity-related conditions such as type 2 diabetes or sleep apnoea
- Are committed to long-term changes in diet and lifestyle
- Are fit enough for surgery
The bariatric team confirms eligibility after reviewing your BMI, health conditions and tests.
Types of bariatric surgery
The team recommends the procedure that suits your health and goals:
Gastric sleeve
About three-quarters of the stomach is removed, leaving a narrow tube-shaped stomach.
Gastric bypass (Roux-en-Y)
A small stomach pouch is connected directly to the small intestine.
Mini gastric bypass
A variation of bypass with a single intestinal connection.
Gastric balloon
A non-surgical, temporary option placed endoscopically, for selected patients.

How much weight will I lose?
Weight loss varies from person to person and depends on the procedure and on diet and lifestyle after surgery. The team will discuss realistic expectations.
