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.
