Mumbai, India (PressExposure) January 11, 2010 -- Gastric bypass, one of the safest weight loss surgeries, is the favored procedure among the surgeonâs in United States and the world over. Surgeons prefer this surgery because it has fewer complications than other available weight loss surgeries and is much safer. It can provide long-term, consistent weight loss if accompanied with ongoing behavior changes.
The procedure involves reduction in the size of stomach by creating a small pouch at the top of the stomach using surgical staples or a plastic band. The smaller stomach is connected directly to the middle portion of the small intestine (jejunum), bypassing the rest of the stomach and the upper portion of the small intestine (duodenum).
This connection redirects the food, bypassing most of the stomach and the first section of small intestine, the duodenum. Food enters directly into the second section of the small intestine, the jejunum, limiting oneâs ability to absorb calories. Even though food never enters the lower part of the stomach, the stomach stays healthy and continues to secrete digestive juices to mix with food in the small intestine.
The surgery is very effective because it makes the stomach smaller and allows food to bypass part of the small intestine. One tends to feel full more quickly than when the stomach was its original size, which reduces the amount of food one eats and thus the calories consumed. Bypassing part of the intestine also results in fewer calories being absorbed. This leads to weight loss.
The various advantages of Gastric bypass or Roux-en-Y gastric bypass are:
â¢ Right after surgery, most patients lose weight quickly and continue to lose for 18 to 24 months after the procedure. Although most patients regain 5 to 10 percent of the weight they lost, many maintain a long-term weight loss of about 100 pounds.
â¢ Surgery improves most obesity-related conditions. For example, in one study blood sugar levels of 83 percent of obese patients with diabetes returned to normal after surgery. Nearly all patients whose blood sugar levels did not return to normal were older or had lived with diabetes for a long time.
Many individuals report having developed a newfound sense of well being after weight loss surgery. People who undergo weight loss surgery can usually expect: â¢ Improvement in or elimination of conditions associated with morbid obesity, including adult onset diabetes, hypertension, sleep apnea and arthritis and joint problems.
â¢ Improved ability to engage in physical activity
â¢ A loss of 50 to 70 percent of that weight above the ideal body weight. This loss usually occurs during the 18 months following surgery.
â¢ Maintenance of this weight loss.
