Weight loss Surgery
Types of Weight Loss Surgeries
Restrictive surgeries work by shrinking the dimensions of the stomach and slowing down digestion. A normal stomach can hold about 3 pints of food. After Weight Loss Surgery, the stomach may initially have as little as an oz, although later that would stretch to 2 or 3 ounces. The smaller the stomach, the less you'll eat. The less you eat, the more weight you lose.
Malabsorptive/restrictive surgeries change how you take in food. They give you a smaller stomach and remove or bypass part of your digestive tract, making it harder for your body to absorb calories. Doctors rarely do purely malabsorptive surgeries -- also called intestinal bypasses -- anymore due to the side effects.
Implanting a device, the most recent of the three techniques prompts weight loss Surgery by interrupting nerve signals between the stomach and the brain.
Adjustable Gastric Banding
What it is: Gastric banding may be a sort of restrictive weight loss surgery.
How it works: The surgeon uses an inflatable band to squeeze the stomach into two sections: a smaller upper pouch and a more extensive lower section. The two teams are still connected by a tiny channel, which slows down the upper bag's emptying. Most people can only eat a 1/2 to 1 cup of food before feeling too full or sick. The food also must be soft or well-chewed.
Pros: This operation is simpler to do and safer than gastric bypass and other functions. You get a smaller scar, recovery is typically faster, and you'll have surgery to get rid of the band.
You can also get the band adjusted in a doctor's office. To tighten the band and further restrict your stomach size, the doctor injects more saline into the band. To loosen it, the doctor uses a needle to get rid of liquid from the band.
Cons: People who get gastric banding often have less dramatic weight loss than those who earn other surgeries. They may even be more likely to regain a number of the load over the years.
Risks: One of the most common side effects of gastric banding is vomiting after overeating too quickly. Complications with the band can happen. It might slip out of place, become too loose, or leak. Some people need more surgeries. As with any operation, infection is a risk. Although unlikely, some complications can be life-threatening.
