What is gastric bypass?

Gastric bypass is commonly used to get rid of extra fat. This procedure is done with precision. During gastric bypass surgery, the stomach is divided into two parts - the smaller top portion and a larger lower part. The small part acts as a pouch and the food is bypassed through it, without entering the lower part. The small intestine is connected to the small pouch. After the operation, the intestine looks like a Y. Gastric bypass works in two ways - firstly, by reducing the size of the stomach, the amount of food ingested is decreased, thus ensuring fewer calories, and secondly, the food does not enter the other half of the stomach thereby decreasing absorption. It might take more than a month for recovery.

Who qualifies for gastric bypass surgery?

Gastric bypass is for patients who suffer from severe obesity and it’s done when all other methods of weight reduction like dieting and exercising have failed. It is recommended to patients who have:

  • BMI more than 40

Why is gastric bypass conducted?

The main objective of bypass surgery is weight reduction, but apart from obesity, there are several other reasons for gastric bypass. It is used for reducing obesity-related disorders such as:

  • High cholesterol

  • Ensures long-lasting weight loss

What are the complications?

  • Hernia: internal hernia because of rearrangement of muscles and bowel obstruction
  • Infection: infection due to release of bacteria in the abdomen after the operation
  • Haemorrhage: during operation, sometimes, the vessels are cut, which might leak after the operation. This is the main reason for hemorrhage after gastric bypass
  • Dumping syndrome: after consuming dessert or something sweet, food enters the intestine and a lot of gastric fluids is needed to dissolve the sugar. This causes Dumping Syndrome.
