Bariatric surgery involves various surgical procedures done on patients who are extremely overweight. Long term weight loss most often accomplished by modifying hormone levels through standard of care techniques, involves the regulation of appetite and metabolism, resulting in a stable new hormonal weight setting point. Most common weight loss surgery procedures use the procedure in conjunction with diet and exercise, and even some surgical procedures are performed alone if obesity is due to a medical condition and cannot be treated by diet and exercise alone. Generally, bariatric surgery is only performed on severely obese adults or patients who have health issues that make successful weight loss unlikely.
Today, gastric bypass surgery and the attainment of a capsule balloon is one of the most common weight loss surgery options available. It allows morbidly obese adults and children to lose an average of thirty pounds in a year through the use of a small stomach band. The band is surgically connected to the lower part of the small intestine so that food can bypass the upper portion of the stomach. Because of the way it is designed, food usually leaves the stomach immediately after eating through the band.
While the surgery has been used to treat obese people for decades, it was not until the last decade that its effectiveness as a weight loss treatment became clear. As more studies were conducted on the surgery, it was discovered that it helped reduce calorie intake by about twenty percent without affecting proteins or fat. Because of these new findings, bariatric surgery is now commonly used to treat obesity and those at risk for obesity. Ideal candidates for this surgery are patients who are severely obese and cannot otherwise lose weight through lifestyle changes. Bariatric surgery is performed under general anesthesia, and it usually takes between one and four hours to recover from the surgery.
Although bariatric surgery offers many benefits, there are some risks that you should be aware of. These include: the possible regrowth of blood vessels after the surgery, blockage of some blood vessels (these may lead to anemia), nerve damage, excessive bleeding, excessive scar tissue formation, infection, bowel or bladder problems, fluid retention, fluid accumulation in the abdominal area, allergic side effects, heart abnormalities, stroke, fluid buildup in the lungs, high blood pressure, and pulmonary embolism. The above risks are generally considered to be rare, but they do occur in a small number of cases. You should discuss these risks with your doctor and weigh them against the benefits of weight loss surgery to determine if it is the right procedure for you.
