Gastric bypass surgery part 3
Obesity and overweight are a global health problem as the number of people suffering from obesity is constantly increasing, and obesity is a serious problem because it leads to physical diseases and psychological disorders such as type 2 diabetes, high arterial tension and diseases of the musculoskeletal system, so science and medicine always work to find solutions to obesity and thus reduce the risks and diseases related to it.
What is the weight loss mechanism in gastric bypass surgery?
The gastric bypass operation is one of the most important operations in the field of weight loss, as the person then loses a large amount of weight quickly and effectively, as:
1) In the process of gastric bypass, the stomach is cut and divided into two parts, a small upper section and a large lower section. His appetite for food.
2) The gastric bypass process connects the small upper part of the stomach to the middle of the small intestine, so the food moves from the upper part of the stomach to the middle of the intestine directly. This process is called diversion, as it helps in losing weight by reducing the rate of absorption of nutrients and calories through the small intestine.
Is it necessary to stop smoking before the gastric bypass operation?
Smoking increases the rate of side effects and risks after surgery, so smoking must be stopped for several weeks before and after the operation.
What are the side effects of gastric bypass surgery?
Gastric bypass surgery is one of the most important operations in the field of weight loss and obesity treatment, but it can be associated with some damages and side effects:
1- Feeling of nausea that may continue for two months after the operation.
2- An allergy to certain foodstuffs may develop, and this sensitivity may last for several days.
3- The so-called rapid gastric emptying may occur, as in the process of gastric bypass, the stomach is connected to the middle of the small intestine, and food moves directly from the stomach to the small intestine quickly, which leads to a feeling of nausea and general fatigue.
4- Diarrhea: The process of gastric bypass reduces the rate of absorption through the intestine, so it may cause diarrhea as a result of connecting the stomach directly to the middle of the small intestine, so food moves directly to the middle of the small intestine without passing through the entire small intestine.
5- Lack of nutrients in the body and lack of vitamins and minerals, so the doctor asks to take vitamins and nutritional supplements after the operation, as the mechanism of weight loss in the gastric bypass process depends on reducing the rate of absorption of nutrients and calories.
6- A narrowing may occur in the opening that connects the stomach to the middle of the small intestine, and this narrowing gradually increases, which leads to food reflux and vomiting.
7- Gallbladder stones may occur due to rapid weight loss.
8- The upper small part of the stomach may expand again and return to its normal position.
The operation of gastric bypass is done by dividing the stomach into two small upper and lower large sections, as the small upper section is responsible for receiving food, which leads to reducing the quantities of food eaten and feeling full for a long time, and thus effectively losing weight and getting rid of the problem of obesity, which is considered one of the most important weight-loss operations and the most widespread due to its high success rate.
