Weight loss surgery is one option for those who suffer from obesity to help get their weight down to a healthy level. However, it is not appropriate for those who are only slightly overweight or moderately obese. Before you go ahead with the surgery, you need to consult with a doctor to find out of if it is a suitable option for you.

The least invasive weight loss surgery is lap band surgery. The surgery involves putting an inflatable ring around the upper part of the stomach, which shrinks the stomach, thereby reducing appetite. The device can be adjusted over time for different levels of weight loss, however, diet and exercise is important to maintain the weight loss.

Vertical banded gastroplasty is another type of weight loss surgery that involves stapling the stomach to reduce appetite. However, there are some risks involved, sometimes resulting in death.

Another weight loss surgery is Roux-en-Y gastric bypass. In this procedure, the stomach is made smaller and made to bypass the upper part of the intestine, thereby reducing appetite and limiting absorption of calories. There are risks with this surgery, including "dumping syndrome", which means the stomach contents moves to rapidly through the small intestine.

Yet another weight loss surgery is biliopancreatic diversion. In this procedure, a large part of the stomach is removed. This restricts the amount of food as well as stomach acid production. This means that most calories and nutrients are rerouted to the colon where they are not absorbed. This can often result in nutrient deficiencies which is why this procedure is rarely used.

Finally, the last weight loss surgery is liposuction. In this procedure, fat is a suctioned out of the body using a high powered surgical vacuum. This means making incisions in the affected areas, which may leave scarring.

It is recommended that weight loss surgery be used as a last resort if diet and exercise are not working, or if you are extremely obese. It is also important after you recover from weight loss surgery to watch your diet and get exercise.
