Gastric bypass surgery is one type of procedure that can be used to cause significant weight loss if you are very obese. The surgery reduces your body's intake of calories. Calorie reduction is accomplished in two ways:
- 1. After the surgery, your stomach is smaller. You feel full faster and learn to reduce the amount that you eat at any given time.
- 2. Part of your stomach and small intestines are literally bypassed (skipped over) so that fewer calories are absorbed. Unfortunately, sometimes nutrients are lost as well.
The surgery is performed under anesthesia, there are two basic
-
STEP 1 -- The first step in the surgical procedure makes your stomach smaller. the surgeon divides the stomach into a small upper section and a larger bottom section using staples that are similar to stitches. The top section of the stomach (called the pouch) will hold your food.
-
STEP 2 -- After the stomach has been divided, the surgeon connects a section of the small intestine to the pouch. When you eat, the food will now travel from the pouch through this new connection ("Roux limb"), bypassing the lower portion of the stomach. The surgeon will then reconnect the base of the Roux limb with the remaining portion of the small intestines from the bottom of the stomach, forming a y-shape.
This "y-connection" allows food to mix with pancreatic fluid and bile, aiding the absorption of important vitamins and minerals. You still may experience poor absorption of certain nutrients.The risk of malabsorption is of greater concern in gastric surgeries that skip over a larger portion of the small intestines. These are performed much less commonly than the Roux-en-Y gastric bypass as described.

All those of bypass gastrico. Very good lost of weight in almost all of the patients for many years. Low index of re-operations on a long term.
EXPECTATIONS AFTER SURGERY
The weight loss results of gastric bypass surgery are generally good. Most patients lose an average of 10 pounds per month and reach a stable weight between 18 and 24 months after surgery. Often, the greatest rate of weight loss occurs in the very beginning (that is, just following the surgery when you are still on a liquid diet).After the surgery, you will need to follow up with your doctor fairly often during the first year. During those visits, your physician will be evaluating your physical and mental health status, including any change in weight and your nutritional needs. You will likely see a dietitian during those visits as well.The surgery is not a solution in and of itself. While it can train you to eat smaller quantities and feel full more quickly, you still have to do much of the work. To achieve weight loss and avoid complications from the procedure, you must exercise and eat properly.
