Bariatric and Metabolic Surgery

Bariatric Surgery is the use of gastrointestinal surgery to help severely obese patients lose weight.

It is the most effective treatment for morbid obesity, producing durable weight loss, reduced health problems, and longer life.

This multidisciplinary programme will include clinical assessment, dietary and lifestyle recommendations, preoperative tests, laparoscopic operation, and regular follow-up.

Metabolic Surgery involves operating on the GI tract to achieve biochemical effects for a potential health gain.

It has proven effective in the improvement of metabolic diseases, including type 2 diabetes, high blood pressure, and hyperlipidemia.
