Obesity is arguably one of the most dangerous diseases faced by many people in the industrialized world. Among the available treatments for obesity is a type of bariatric surgery called Gastric Bypass. This procedure is generally limited to patients who have a Body Mass Index (BMI) of 40 or over, or patients with a BMI of 35 who have other serious illnesses such as diabetes, sleep apnea, or joint disease. Gastric bypass, before and after surgery, helps a patient make and maintain significant lifestyle changes.

Gastric bypass surgery is a procedure where the stomach is cut in order to create two sections, as well as a cut made in the small intestine. The small section made from the stomach is then connected to the portion of the small intestine that is connected to the large intestine. The larger section of stomach is then sutured to the intestine so that it can continue to release digestive juices and hormones.

In this way, gastric bypass surgery helps a person lose weight through several mechanisms. Since the smaller stomach section holds about an ounce of food, the person feels full after consuming a small amount of food. Additionally, this process forces the food to bypass the majority of the stomach and upper intestine, which makes it possible for the body to absorb fewer calories. Finally, metabolism is improved by altering the way various hormones are released.

You will notice a difference in dietary needs required by gastric bypass before and after surgery. Before surgery, you may be used to large meals. After surgery, you will need to eat smaller amounts. Since food needs less time to digest, but you may need to eat more frequently. If you continue to eat after feeling full, you will feel discomfort and possibly feel the urge to vomit. Your doctor may also recommend nutritional supplements after the gastric bypass.

You need to consult with your physician to discuss the pros and cons of lifestyle changes you can make by incorporating gastric bypass, before and after the process.
