Bariatric surgery is surgery that is designed to decrease body weight, thereby giving obese patients access to better health and more desirable body shapes. This type of operation typically reduces the dimensions of the stomach via a gastric band. Sometimes, part of the stomach may be removed in order to get the desired result. Since less food fits into the stomach after surgery, patients feel fuller, even when consuming small or very small meals. In this manner, fewer calories are consumed and fat stores are burned away quite rapidly.
Like all forms of surgery, bariatric surgery comes with risks. Those who are considering this form of surgery should seek out expert medical advice. Typically, doctors will recommend this form of surgery to patients who are having trouble losing weight via conventional means, such as exercise and diet.
Patients who are suffering from health problems related to obesity (or who are at very high risk for developing health issues related to their weight) are optimal candidates for this form of surgery. However, some people may seek out bariatric surgery for reasons of vanity alone. Since weight loss experienced after bariatric surgery is very pronounced, many patients who’ve undergone bariatric surgery find the results of their operations to be life-changing.
A lot of patients experience increases in self-esteem due to achieving more conventionally-attractive body shapes. In addition, the may feel healthier and more energetic. However, it is possible to regain weight that is lost after bariatric surgery. Patients who wish to remain at a goal weight should take care to eat healthy foods in moderation and to get regular exercise. By choosing a healthy lifestyle, patients will prolong the positive results of their bariatric surgery.
When part of the stomach is taken away, the surgery may be called sleeve gastrectomy or biliopancreatic diversion with duodenal switch. Gastric bypass surgery is another sort of bariatric surgery, which happens when the small intestine is resected or rerouted to a compact stomach pouch. Guidelines for Bariatric Surgery Candidates
According to the United States National Institute of Health, bariatric surgery is intended for those who have body mass indexes of 40 or higher. People with BMIs (body mass indexes) of 35, as well as serious health problems, may also be candidates for this type of surgery.
Bariatric Surgery Processes
This type of operation may work in one of two ways. The two bariatric surgery processes are restriction and malabsorption.
Restriction surgery will happen when the stomach is operated on so that it can’t stretch to its full size. Typically, a stomach will hold six cups of food. After bariatric surgery with a restriction focus, only a cup of food will fit into the stomach cavity. This type of surgery works by giving patients feelings of fullness, or satiety, after they’ve eaten very little.
The second bariatric surgery process, malabsorption, moves food through a section of intestine in a different way and bypasses the area where calories are absorbed. Because fewer calories are taken in, weight is lost very quickly. This type of surgery may be known as laparoscopic surgery, whereby five or six inch-long cuts are made in the stomach wall. The surgeon will use tools and a camera in order to operate through these holes.
Screening for Bariatric Surgery May Include Psychological Tests
Before giving a patient the green light to proceed with bariatric surgery, a surgeon must be certain that the patient has realistic expectations. A detailed consultation will be required, and psychological screening tests may be given in order to assess a patient’s state of mind before scheduling a procedure. For example, those with eating disorders, such as bulimia nervosa, may not be good candidates for this type of surgery.
Today’s bariatric surgery procedures are safer than ever before. However, as with all surgery, there is risk of infection and complications. That’s why it’s so important to have a team of medical experts (such as board-certified surgeons and licensed family physicians) by your side as you embark on this type of weight-loss journey.
