Weight loss surgery can be a viable medical intervention for obesity where the patient has a BMI of over 30. A person with a BMI of over 40, or whose BMI is over 35 and who has been diagnosed with obesity related conditions, such as diabetes type 2 or high blood pressure, is considered to be clinically, severely obese.

Although weight loss surgery is not a quick fix or a short cut to healthy weight loss, it can be a great start for people who have struggled to lose weight or to maintain their weight loss.

Malabsorptive weight loss surgery options such as gastric byp[censored] surgery are procedures that help the patient to lose weight in two ways. The surgery reduces the size of the patient's stomach, meaning that the patient is able to eat a lot less food before feeling full, thereby significantly reducing calorie intake. At the same time it reduces the amount of calories, in the form of food and drink, that is absorbed by the digestive system into the blood, where it is stored as fat. This lessened supply of calories causes dramatic weight loss.

Gastric Byp[censored] Surgery

One of the most successful weight loss surgery options for patients who require malabsorptive weight loss surgery is Gastric Byp[censored] Surgery, or the Roux-en-Y gastric Bypass. This weight loss surgery option constitutes of around 80% of all weight loss surgery performed in the United States.

A combination of both restrictive weight loss surgery (where the stomach capacity is reduced) and malabsorptive surgery, the gastric byp[censored] can be performed as open surgery or as a laparoscopic procedure.

Before gastric byp[censored] surgery, food is passed from the stomach and through the small intestine, where the majority of the calories are absorbed. Following this, the remaining food passes to the large intestine, where it is processed; remaining calories are absorbed and waste is passed on to the colon.

During gastric byp[censored] surgery the patient's stomach is divided into two sections, where the lower section is sealed off from the upper section. The upper section of the stomach is then connected direct to the middle of the small intestine, bypassing the lower stomach and the upper part of the small intestine. This byp[censored] procedure means that fewer of the calories ingested are made available to the body as energy, so the body draws on stored energy, in the form of fat. This leads to dramatic weight loss.

Gastric byp[censored] is the best option for severely obese patients who are considered healthy enough to undergo the surgery and who need to lose weight quickly. Because of the dramatic weight loss associated with gastric byp[censored] surgery, health benefits such as reduction of severity or even remission in obesity related conditions such as type 2 diabetes, heart conditions, high blood pressure, sleep apnea and arthritis are noticeable within months, and sometimes weeks, of the weight loss surgery.
