For morbidly obese people, losing weight can be a never-ending battle. There are a number of people who have struggled for years to get rid of the extra bulging flesh from their body but to no avail.
Such obesity sufferers who have failed to achieve their goal weights by diet, exercise and slimming pills, can substantially benefit from a variety of weight loss surgery procedures available.
Obesity is fast spreading like a forest fire around the globe, and in many countries including the United States it has become a grave health concern. It is estimated that nearly 64.5 percent of adult population in the Unites States or about 127 million are obese, and 5 to 10 millions of them are morbidly obese. The World Health Organization (WHO) has predicted that nearly 2.3 billion people will be overweight and over 700 million of them will be obese by the year 2015.
In the past decade, the explosive growth in obesity and morbid obesity rate has given a significant boost to the popularity of bariatric surgery.
There are various kinds of bariatric surgery procedures that can give you respite from the excess flab you have accumulated on your body over the years. These weight loss surgeries have a history of proven success in helping obese patients achieve substantial and long-term weight loss.
Listed below are different surgical weight loss procedures:
Gastric Bypass: It is a popular weight loss surgery which is alternatively known as Roux-en-Y (RNY) gastric bypass surgery. The surgery calls for the reduction of the stomach size and the length of the small intestine. During the surgery, a bariatrician attaches a Y-shaped section of the small intestine directly to the newly formed smaller upper pouch, which allows food to bypass rest of the stomach and a large portion of the small intestine. That helps in limiting the absorption of calories and nutrients, thus allowing the patients to feel fuller sooner.
Gastric bypass is the most frequently performed weight loss surgery in the United States. Gastric bypass beneficiaries can expect to lose up to 65% of their excess body fat. Following the surgery, patients may be able to leave the hospital after two days and it may take them 1 to 2 weeks to return to light work.
Gastric Sleeve: Gastric sleeve surgery or sleeve gastrectomy as it is widely known is a procedure of stomach reduction in which a bariatric surgeon permanently removes about 85 percent of the stomach. Following the surgery, the stomach takes the shape of a tube or sleeve. This banana-like tube creates a restrictive process that restricts the amount of food patients consume. After the gastric sleeve surgery your stomach becomes smaller, you feel full a lot quicker than you are used to, and consequently you lose weight.
Gastric Band: Also called laparoscopic gastric banding, this kind of bariatric surgery is second most commonly performed weight loss surgery, after gastric bypass. Lap band surgery is a reversible and relatively less invasive procedure, in which a silicone band is secured around the upper part of the stomach, dividing it into two parts. The newly created stomach pouch can hold little amount of food at one time, which helps patients lose weight. Lap band surgery is much safer than gastric bypass and gastric sleeve and has fewer risks. Gastric banding patients can expect to lose 50 to 60 percent of their excess weight.
Gastric Plication: It is a laparoscopic procedure that reduces the size of the stomach without removing sections of the stomach or re-routing intestine or implanting devices. During the laparoscopic gastric plication, a surgeon reduces the stomach volume by folding the stomach inwardly.
The surgery reduces the stomach volume by 70%, therefore limits food intake. The gastric plication is reversible bariatric procedure and can be converted to another procedure if needed.
Duodenal Switch: The duodenal switch (DS) is a restrictive and malabsorptive weight loss surgery procedure in which approximately 70% of the stomach is removed to create a cylinder-shaped pouch, connecting the remaining portion to the top of the small intestine, instead of the duodenum.
Commonly referred to as the BPD/DS, or simply the Switch, the duodenal switch has proven to be successful in previous studies. Some studies have confirmed that DS could effectively treat diabetes and sleep apnea and could be more effective at improving the hypertension as well.
