Today, it’s no secret that a large percentage of the population is struggling with obesity and weight loss. Losing weight can be an extremely frustrating and overwhelming task, because it takes time before an individual can see any desirable results. Additionally, there’s a lot of misinformation on the correct steps to take in order to lose weight. In such cases, weight-loss surgeries can help. Once a qualified doctor like Dr. James W. Stalker has decided that surgery is appropriate, there are several options available that one can take.
Bariatric surgery is meant to eliminate the health risks associated with obesity and being overweight, and to do so in a very short amount of time. Examples of major weight loss surgeries include sleeve gastrectomy, Roux-en-Y gastric bypass, duodenal switch with biliopancreatic diversion and laparoscopic adjustable gastric banding.
Bariatric surgery can be classified into two areas depending on how it works. It can be restrictive or malabsorptive. With restrictive surgery, the stomach size is physically shrunk in order to reduce the amount of food it can take in and to slow down digestion. This restricts the total amount of calories a person can consume. The malabsorptive technique changes how one takes in food, making the stomach smaller and removing parts of the digestive tract so as to make calorie absorption harder.
Roux-en-Y gastric bypass
This type of surgery uses some sort of restriction technique. A sack is created on the upper part of the stomach which acts as a bypass for receiving food. A hole is then made on the stomach and subsequently connected to the sack to allow food and gastric juices to travel from the sack to that particular section in the intestine. Due to the small size of the sack the amount of food that one consumes drastically reduces. This, in turn, minimizes the number of calories and nutrients that are absorbed by the body, which results in loss of weight.
In this type of bariatric surgery, a portion of the abdomen is divided and detached from the rest of the body. The portion that is left is then manipulated to create a shape that resembles a tube that can hold a very little amount of food. Additionally, the surgery greatly reduces the levels of ghrelin produced, which is the hormone responsible for regulating appetite. This surgery does not tamper with the body’s normal absorption of nutrients and calories, but rather minimizes one’s desire to consume more food.
Laparoscopic adjustable gastric banding
In this procedure, a strip holding an inflatable balloon is placed above the abdomen and secured. This creates a small sack on top of the strip, with a tiny hole that connects it to the stomach. A port is then placed just below the surface of the skin to join the strip via another tube. The size of the strip can then be easily adjusted by injecting or sucking the fluid from the port, which inflates and deflates it respectively. It therefore limits the volume of food held by the stomach, in turn reducing the amount of food consumed. The rate at which nutrients and calories are absorbed in the body is not affected but the levels consumed are minimized due to less intake of food.
