Pros and Cons of Weight Loss Surgery

Weight loss surgery or bariatric surgery is medically advised if a person is severely obese and have diabetes or any other obesity-related medical condition or in some cases, the person’s body mass index (BMI) is over 37.5, with no accompanying health condition.

Moreover, it is also referred when BMI of the person is over 32.5 and also s/he is accompanied by obesity-linked diabetes, high blood pressure, high cholesterol or obstructive sleep apnoea (OSA).

Mainly, there are 4 types of bariatric surgery procedures: laparoscopic sleeve gastrectomy (gastric sleeve), gastric bypass, gastric band, and duodenal switch. Among these 4, the gastric sleeve and gastric bypass are among the top choices by patients to lose weight through surgery.

In gastric sleeve surgery, Parts of the stomach is actually removed, make a person feel full after eating food in a very less amount as well. Only a small banana-shaped section is left behind.

In gastric band surgery, a ring with an inner inflatable band is placed which surrounds the top of a patient’s stomach, creating a small pouch. This band reduces the size of the stomach, so with a very less amount of food the person is full. The band is made up of a balloon filled with a saline solution whose size can be increased or decreased the size of the pouch’s opening by either injecting or removing solution by the surgeon.

Gastric bypass surgery is, however, more complex, because it actually makes your stomach smaller while rerouting digestion. It is often performed by stapling the stomach, to create a pouch in the upper section that effectively works as your stomach.

Then, the surgeon will cut the small intestine which s further attached directly to the stomach pouch. When a person eats food, it ends up skipping parts of the stomach and the upper small intestine. Which means that the body absorbs fewer calories from food since it’s not digesting as much. The skipped part of the stomach part will be then connected to the lower part of the small intestine. However, the bypassed section remains attached to the main part of your stomach, allowing digestive juices to still reach it.
