Sleeve Gastrectomy surgery is the most common and popular bariatric surgery procedure today. Sleeve Gastrectomy surgery was first performed to weaken patients with a body mass index above 60 and prepare them for more aggressive surgeries. However, it has been a bariatric surgery method alone since it has been observed that the weight efficiency of these patients is very good.
Effect Mechanism of Sleeve Gastrectomy Surgery
We can group the mechanism of action of Sleeve Gastrectomy surgery under three headings. These are a decrease in stomach volume, hormonal changes, and mechanical changes.
Decreasing stomach volume is undoubtedly very important for weight loss. Studies have shown that the smaller the stomach volume decreases, the greater the weight loss. After Sleeve Gastrectomy surgery, stomach emptying occurs. This causes the foods we eat to remain in our stomach for a longer time and longer satiety.
In the stomach reduction surgery, the fundus part of the stomach is also removed. A hormone called Ghrelin is secreted from the fundus part of the stomach. The hormone Ghrelin increases in hunger and increases our appetite, increasing our consumption of food. When we are saturated, this hormone decreases. Studies have shown that when there is satiety in obese people, this hormone does not decrease. It has been observed that this hormone drops until the first year after stomach reduction surgery.
Glucagon-like peptide-1 (GLP-1) increases the release of insulin from our pancreatic gland and reduces the release of glucagon hormone. It also reduces stomach emptying, causing satiety. Studies have shown that the release of the hormone GLP-1 after Sleeve Gastrectomy surgery increases.
After hormonal changes occurring after stomach reduction surgery, many diseases related to obesity appear to improve. Type2 Diabetes, High Blood Pressure, Sleep Apnea, High Cholesterol, Fatty Liver are the main ones.
