Weight Loss Surgery - Gastric Bypass Surgery

The gastric bypass procedure is a type of bariatric surgery or weight loss surgery designed to reduce your food intake if you have tried and failed to lose weight through diet and exercise. People who have bypass operations generally lose two-thirds of their excess weight within 2 years. There are two types of Gastric Bypass Operations :

Roux-en-Y Gastric Bypass (RGB)

1. Roux-en-Y Gastric Bypass (RGB)

Average Costs : $23,000

It is the most common gastric bypass procedure performed in the U.S. First, a small stomach pouch is created by stapling part of the stomach together or by vertical banding. This limits how much food you can eat. Next, 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 the jejunum.

This causes reduced calorie and nutrient absorption. This procedure can now be done with a laparoscope (a thin telescope-like instrument for viewing inside the abdomen) in some people. This involves using small incisions and generally has a more rapid recovery time.


Extensive Gastric Bypass

2. Extensive Gastric Bypass - Biliopancreatic Diversion (BPD)

In this more complicated gastric bypass operation, the lower portion of the stomach is removed. The small pouch that remains is connected directly to the final segment of the small intestine, thus completely bypassing both the duodenum and jejunum. Although this procedure successfully promotes weight loss, it is not as widely used because of the high risk for nutritional deficiencies.

4 Risks For Associated With Gastric Bypass Surgery

Gastric bypass operations also may cause "dumping syndrome," whereby stomach contents move too rapidly through the small intestine. Symptoms include nausea, weakness, sweating, faintness, and, occasionally, diarrhea after eating, as well as the inability to eat sweets without becoming extremely weak. Gallstones can occur in response to rapid weight loss. They can be dissolved with medication taken after the surgery. People who undergo this procedure are at risks for :

  1. Pouch Stretching -- Stomach gets bigger overtime, stretching back to its normal size before surgery.
  2. Band Erosion -- The band closing off part of the stomach disintegrates
    Breakdown Of Staple Lines -- Band and staples fall apart, reversing procedure.
  3. Leakage Of Stomach Contents Into The Abdomen -- This is dangerous because the acid can eat away other organs.
  4. Nutritional Deficiencies Causing Health Problems.

Gastric Bypass Surgery Recovery And After Care

After gastric bypass surgery, many patients spend two to three days in the hospital, or one to two days for the laparoscopic procedure. On average, most people require two to five weeks of recovery before returning to normal activities.

For a number of days, the abdomen will be swollen and sore, and the patient often feels discomfort. Your doctor can prescribe medications to help you manage the discomfort. All the techniques will leave a permanent scar, but scarring is normally covered by clothing.

Aftercare treatments typically include a dietary plan, regular exercise, behavioral-modification therapy, and vitamin supplements. Your weight loss surgeon or plastic surgeon might require the use of a dietician, an exercise program, and possibly a psychologist for an extended period of time to assist you in your recovery.
