Gastric bypass surgery is a common form of weight loss surgery that results in outstanding weight loss with minimal side effects. But once you undergo the gastric bypass surgery procedure you have to accept lifelong changes in your diet. The post-diet of gastric bypass surgery includes an adequate intake of protein, taking vitamin and mineral supplements including multivitamin, iron and calcium, B12 and avoiding sweets and fatty foods.
Types of gastric bypass surgery
In gastric bypass surgery, the surgeon takes off a large portion of the stomach leaving behind a tiny pouch. It is this small pouch that prevents overdose of eating as it can take very less amount of food. Moreover, with large parts of your stomach and small intestine bypassed, most of the nutrients and calories in the food do not get absorbed at all. This helps the person from gaining excess weight.
There are several types of bypass surgery operations.
They are:
§ Roux-en-Y gastric bypass [RGB] - this is a common surgery where a small stomach pouch is created by stapling part of the stomach together or by vertical banding. This reduces the amount of food to be taken. Then a Y-shaped section of the small intestine is attached to the pouch to allow food to bypass the duodenum as well as the first portion of jejunum. This causes reduced calorie and rapid nutrient absorption.
§ Extensive gastric bypass [biliopancreatic diversion] - in this complicated surgery, the lower portion of the stomach is removed. The small pouch that remains connected to the final segment of the small intestine completely bypasses both duodenum and jejunum.
People who undergo gastric bypass surgery always lose two-thirds of their excess weight within two years.
Risks of gastric bypass surgery
Gastric bypass surgery causes \"dumping syndromes\" where the stomach contents move too rapidly through the small intestine. The usual symptoms of gastric bypass surgeries include weakness, sweating, fainting, nausea, diarrhea, as well as inability to eat sweets.
People who undergo this procedure are at risk of:
§ Band erosion - the band closing off part of the stomach disintegrates
§ Pouch stretching - stomach gets bigger overtime, stretching back to its normal size before surgery
§ Leakage of stomach contents into the abdomen [acid can eat away other organs]
§ Nutritional deficiencies causing health problems
§ Breakdown of staple lines - band and staple fall apart, reversing procedure
Gastric bypass diet
Gastric bypass diet helps the patients to drop 50% to 90% of their overall excess fats. The diet is designed to bring about significant weight loss. It basically includes foods that are high in protein and low in fat, fiber, calories, and sugar. You should have lots of vitamins and minerals. Iron, vitamin, folate and calcium are the best nutrients for patients undergoing gastric bypass surgery.
You can undergo gastric bypass surgery only if you have been obese for at least 5 years, do not have a history of alcohol abuse, and do not possess untreated depression and range between the ages 18 to 65.
