Weight Loss Surgery

Weight loss surgery is an option made available for people suffering from extreme obesity. When obesity has become so serious and pose such a threat to the health of a person which cannot be handled effectively by dieting or exercise, weight loss surgery offers an alternative option that may help provide a means to lose a considerable amount of excess weight. This procedure is also known in medical circles as gastric bypass surgery or bariatric surgery.

Types of Surgical Procedure

There are two main categories in which weight loss surgery belongs in terms of the technique used. One makes use of restrictive procedures that aim to limit the amount of food that the stomach can hold by closing off or removing some parts of the stomach. This type of weight loss surgery prevents one from eating larger amounts of food at any one time but does not interfere with the stomach’s normal digestive processes. Examples of such procedures include gastric bypass, gastric banding and vertical banded gastroplasty.

Another technique used in weight loss surgery is too try and limit the amount of calories and nutrients that can be absorbed by the intestine. This category of weight loss surgery belongs to what is also known as malabsorptive procedures. Examples of such procedures include biliopancreatic diversion and the Roux-en-Y gastric bypass or RGB.

In an RGB procedure, the surgeon creates a small pouch in the stomach that is then directly connected to a lower portion of the intestine. What this does is that food goes through the small stomach pouch and bypasses large portions of the digestive tract as it travels through, thereby limiting the amount of calories and nutrients that it can absorb.

Benefits of weight loss surgery

One of the main benefits of weight loss surgery is that it can provide severely obese people with an effective means of losing weight. Within two years of the surgical procedure, a patient may lose anywhere between 50 to 60 percent of excess weight and can be effectively maintained with regular diet and exercise. Weight loss surgery may also have additional benefits for other conditions that affect people as a result of their severe obesity.

Other diseases such as Type 2 diabetes may be more effectively controlled with weight loss surgery. With the ensuing weight loss patients may also experience some improvements on their high blood pressure as well as with their cholesterol levels. Obstructive sleep apnea, a common condition among obese people characterized by pauses in breathing during sleep, may see a marked improvement after surgery and the ensuing loss of excess weight.

Assessment and Evaluation

The type of weight loss surgery that a doctor would recommend would depend on a person’s weight as well as on his or her medical history. Certain ailments may make some procedures risky for some obese patients.
