What is a gastric sleeve?
‘Gastric sleeve’ refers to a form of weight loss surgery involving the permanent removal of 80-90% of a patient’s stomach. This is done through advanced laparoscopic (keyhole) techniques under a general anaesthetic.
The procedure transforms the stomach into an elongated tube, comparable in shape to a banana. In doing so, it dramatically reduces the holding capacity of the stomach (from around 1½ litres down to just 200mls). The outcome is obviously a reduced ability to consume large quantities of food and in addition, a greater feeling of satisfaction – even after only a small meal.
Dietitians recommend that sleeve gastrectomy patients change their eating habits to support 4 to 6 small meals per day and people considering this weight loss option should factor this into their decision making process.
Following the procedure, and with the adoption of new eating habits, on average patients can expect to lose 60-70% of their excess weight within 12 months.
