Many people are so desperate to loose weight that they are turning to what is called bariatric surgery. Bariatric surgery refers to a family of procedures that can help some people loose weight.
The way bariatric or weight loss surgery works is actually very simple. The surgeon performs a procedure that reduces the patient’s digestive system’s ability to take in food. Reducing the food intake can promote weight loss in some cases.
There are several kinds of popular bariatric surgery available today. One of the most popular is the adjustable gastric band. According to getphenq.com in this surgery, the surgeon places a band around the top of the stomach that limits its ability to take in food.
Gastric bypass or Roux-en Gastric Bypass is a procedure in which the surgeon puts a sort of pouch into the stomach. The pouch is small and it limits the amount of food that the body can absorb through the stomach and the rest of the digestive system.
A very complex procedure that is sometimes used is called the biliopancreatic diversion with a duodenal switch. In this extreme surgery the surgeon actually removes a large portion of the stomach to encourage smaller meal sizes. Food is also re-routed away from the small intestine to make it harder to absorb into the body. Bile and other juices are also rerouted to limit the digestion of food.
In a similar procedure called vertical sleeve gastrectomy the surgeon removes most of the stomach but doesn’t reroute any of the digestive system’s plumbing. This operation limits food intake but doesn’t limit digestion.
Another benefit of this operation is that it may limit production of a hormone called ghrelin. Limiting the production of ghrelin could limit hunger because this hormone may encourage hunger.
There are some serious risks from bariatric surgery including malnutrition, bleeding, infection, blood cots in the legs, lungs and heart, and hernias. The biggest risk is malnutrition which results because the body’s ability to absorb vitamins is limited. This can be limited by taking vitamin pills.
Studies indicate that weight loss surgery doesn’t work for about 10% of the people who undergo it. These individuals will regain all or most of the weight lost because of the surgery.
Those who undergo weight loss surgery will still have to eat a healthy diet and exercise. The research indicates that persons who revert to bad eating habits and a sedentary lifestyle after weight loss surgery could regain the weight.
