Reduce Obesity through Gastric bypass surgery

Gastric bypass surgery is an operation that creates a small pouch to restrict food intake and bypasses a segment of the small intestine. In the gastric bypass procedure, we make a direct connection from the stomach pouch to a lower segment of the small intestine, bypassing the duodenum (the first part of the small intestine) and some of the jejunum (the second part of the small intestine), delaying the mixing of ingested food and the digestive enzymes.

Roux-en- Y Gastric Bypass (RYGB)

RYGB is the most common type of bariatric surgery. We begin by creating a small pouch by dividing the upper end of the stomach. This restricts the food intake. Next, a section of the small intestine is attached to the pouch to allow food to bypass the duodenum, as well as the first portion of the jejunum. The small intestine is re-connected 100 cms (this may vary as per the BMI of the patient) from the pouch to allow ingested food and digestive enzymes to mix.

Restrictive Operations

Alternatives to gastric bypass procedures are restrictive operations such as vertical-banded gastroplasty or adjustable gastric banding. Restrictive surgery results in weight loss when we create a small pouch at the top of the stomach where the food enters from the esophagus. The pouch's lower outlet usually has a diameter of about 1/4-inch. The small outlet delays the emptying of food from the pouch creating a feeling of fullness. Following surgery, patients can usually eat only one half to 1 cup of food without discomfort or nausea. Most people who have a restrictive operation lose the ability to eat a large amount of food at one time. Some patients do return to eating modest amounts of food, without feeling overly hungry. Both operations serve only to restrict food intake and do not alter the normal digestive and absorptive process.

Gastric bypass surgery is today a gloomy treatment for obesity. You should be watchful of this fact that the drugs used to treat can adversely affect kidney function, so risk stay factor after this surgery is acute kidney injury. Another crisis that the patient after this surgery has to endure from is nutritional deficiency. Besides these, bacterial growth may infect the small intestine that led to combination of vitamins, natural resources and calcium and other universal nutrients. The "gastric pouch" that is created in the Roux-en-Y gastric surgery impact the acid producing cells in the stomach lining.
