Weight Loss Surgery For Obesity

What is weight loss surgery (bariatric surgery)?
Weight loss surgeries sometimes called “bariatric surgeries,” are surgical treatments for overweight patients. These are operations to reduce the size of the stomach. Certain surgeries also change the way you eat through the intestines so that you are taking in fewer calories and nutrients.

Who gets bariatric surgery?

The surgeon uses a measurement called body mass index or BMI to determine who needs the Surgery. Your BMI will tell you if your weight is normal for your height.
Bariatric surgery is only suitable for those patients who are unable to lose weight with other methods and for those who:
• Has a BMI over 40; or
• Has a BMI index between 35 and 40, and also has diseases such as diabetes, heart disease, and hypertension.

Is there a difference between the types of bariatric surgery?

Yes. There are different types of weight loss surgery. Most commonly used:
Gastric banding – in this type of operation, the surgeon puts an adjustable band on the upper stomach, with the help of which the upper stomach is reduced and this contributes to rapid saturation since the receptors signaling that the stomach is full are located in the upper stomach. The doctor adjusts the cuff of the bandage to achieve the patient’s comfort and, subsequently, the desired weight.

Gastric bypass (gastric bypass) – in this type of operation, the surgeon disconnects part of the stomach, leaving only a small area for food – “small stomach”. It then connects the “small stomach” to the middle of the small intestine. This results in food shunting or a short food path.

Longitudinal (sleeve) resection of the stomach (gastroplasty), or SLIV-1, is a type of operation that involves removing a large part of the stomach, and a tube, otherwise called a “sleeve”, is formed from the remainder.

Insertion of a gastric balloon is a temporary measure aimed at initial weight loss in patients with obesity and severe concomitant disorders, in order to prepare them for a full-fledged operation.
Currently, gastric banding is losing its popularity, and the most effective operations are longitudinal gastrectomy and gastric bypass surgery.

How is bariatric surgery performed?

Various types of obesity surgeries are performed “open” or “laparoscopically”. With the open method, the surgeon makes a large incision in the abdomen and directly works on the abdominal organs. In laparoscopic surgery, the surgeon penetrates the abdominal cavity to the organs with the help of several punctures, and then introduces manipulator instruments through them. The manipulators are equipped with microinstruments, illumination, and a microcamera, which allow performing operations with visual control, while not making large incisions, which minimizes surgical tissue trauma and shortens the rehabilitation period.

How do the different types of transactions look like in comparison?

Gastric bypass surgery (gastric bypass surgery) leads to the greatest weight loss and works faster, but it is the most serious operation with high risks, especially if the recommendations are not followed in the postoperative period. After gastric bypass surgery, it is very likely that type 2 diabetes mellitus will completely stop. Gastric weight loss surgery can cause problems such as malabsorption, which can lead to malabsorption and nutrient deficiencies and mean your body is lacking in important nutrients. After gastric bypass surgery, your doctor will monitor your body’s nutrient levels.

Longitudinal (sleeve) gastrectomy is a safer and less traumatic method than gastric weight loss surgery because it does not involve redirecting food transit through the gastrointestinal tract and with bowel resection, as a result of which there are fewer problems with absorption and nutritional deficiencies. This operation may even be safer than gastric banding since there is no foreign body in the body. The efficiency of the operation is on average higher than with gastric banding.
