Probably the most well-known bariatric surgery procedure, where the size of the stomach is reduced with the aim to lower its food consumption capacity and increase a faster sense of fullness. The procedure reduces food intake, affects the absorption of nutrients and the secretion of metabolic hormones.
During the procedure the surgeon removes around 70-80% of the stomach, leaving
a narrow gastric tube or ‘sleeve’ from the remaining part. The capacity of this tube
is significantly lower than of the stomach prior to the treatment. The food is not deviated from its usual course in the digestive system.
The estimated results – up to 60-70% excess body weight loss in 1-1.5 years after the surgery. It is important to note that, if you choose this treatment, strong self-control is a crucial success factor in achieving your weight loss goals.
Why this type of surgery is effective?
Gastric sleeve surgery helps patients lose weight in two ways. Firstly, because of the reduced stomach capacity they feel full after each meal quicker and so intake less calories. Secondly, during this surgery the part of a stomach producing hormone gherlin, that’s associated with a feeling of hunger, is removed so patients stop feeling hungry all together.
As mentioned before, strong self-discipline in following the prescribed diet and recommended exercise plan is a key success factor in achieving the desired results. Changing your lifestyle habits will help you to keep the weight off long term.
