Weight-loss surgery can promote better health through long-term weight loss. With sustained weight loss, diseases including type 2 diabetes, high blood pressure, sleep apnea, high cholesterol and osteoarthritis are either greatly improved or completely gone. With disease improvement, medications to treat these problems are reduced or discontinued. Plus, with a big decrease in food intake after the surgery, diabetics often have a huge improvement in blood sugar, even before a large amount of weight is lost.

There are many psychological benefits, too, including improvements in self-esteem, personal confidence and quality of life. With weight loss, most people can return to many of the physical activities they used to enjoy before excess weight prevented their mobility. These range from walking and biking to simply playing in the yard with their children.

The surgery has direct benefits, too. First, people can sustain a long-term eating pattern of caloric restriction (usually around 1,000 to 1,500 calories a day), with increased contentment and no deprivation. When hunger signals kick in, a moderate amount of food can now satisfy. Second, the likelihood of keeping most of the weight off is very high, so while 100-plus pounds of weight loss can be accomplished without surgery, the operation helps tremendously with preventing weight regain.

The laproscopic techniques we now use significantly reduce complications from bariatric surgery but patients must understand that all surgeries carry risks, including a heart attack, blood clot, organ injury or failure, hemorrhage, or infection. While it is very rare in laparoscopic procedures, patients can die during or after surgery. Here are some statistics for weight loss surgery risks:

* The adjustable gastric band has the best safety record with a mortality rate of only 0.1 percent (one in a thousand). Most of the complications occur over time and not at the time of surgery. The most common: problems with the implanted port that enables doctors to adjust the band, which occurs in four percent of cases; poor alignment of the band (called a prolapse), three percent; the band penetrating the wall of the stomach (called an erosion), two percent.

* Gastric bypass has a mortality rate of 0.2 to 0.5 percent (two to five out of a thousand). Postoperative complications include hemorrhages, in three to four percent of cases; leaks along the staple line in the stomach or at the connection between the stomach and bowels, two-and-a-half percent; intestinal obstruction, one to two percent of the time. Long-term complications include vitamin deficiencies, protein malnutrition, intestinal obstructions, marginal ulcers , strictures of the gastric pouch to intestinal leakage, and internal hernias.

* The biliopancreatic diversion procedures have slightly greater postoperative complications than the gastric bypass. Long term complications are similar to those of the gastric bypass, but the risks of protein malnutrition and vitamin deficiencies are greater.

* All of the procedures also have the risk of weight loss failure or weight regain

in my opinion one should really not have a surgery for losing weight, there are other many ways mentioned.

Risks are more than the benefits.
