Bariatric surgery is an effective operation that helps obese individuals lose weight by making changes to their digestive system. In fact, studies have shown that people lose approximately 15 to 30 percent of their initial weight on average after undergoing surgery. This surgery changes the anatomy of the gastrointestinal tract and causes physiological changes that alter the energy balance and fat metabolism for long-term weight loss. Some types of bariatric procedures work by reducing the size of the small intestine, which absorbs calories and nutrients from foods. Other bariatric procedures work by reducing the overall size of the stomach allowing individuals to eat less food.
By changing the stomach and digestive system, the production of intestinal hormones reduce hunger and appetite while increasing the feeling of fullness. Interesting enough, the surgically induced hormones have an opposite effect to dietary weight loss. Unlike the dietary weight loss methods that reduce energy expenditure in the body, this method improves weight loss by enhancing energy. Therefore, weight loss as a result of bariatric surgery is more likely to last longer than that of dietary methods.
Who should opt for bariatric surgery?
This type of surgery is suitable for adults with a body mass index of 40 or more. They are also suitable for adults with a BMI of 35 or more who also suffer from obesity-related conditions such as sleep apnea, heart disease, and type 2 diabetes. Individuals with a BMI of 30 or more who also suffer serious health conditions can choose the gastric band procedure only as a form of bariatric treatment. Studies have also found that bariatric surgery is safe for teens and can help improve weight-related conditions for at least three years after surgery.
The benefits of bariatric surgery
Studies have shown that those that undergo bariatric surgery typically have long-term weight-loss success. More than 90-percent of individuals that suffer from severe obesity are successful in keeping off at least 50-percent of their excess weight loss after surgery. Other studies have found that patients have an increased lifespan after undergoing surgery as those suffering from severe obesity tend to have lowered their risk of death. Bariatric procedures also result in an improved overall quality of life by allowing better mobility and an increase in mental health.
The popular types of bariatric surgical options
The most common types of bariatric surgery operations include laparoscopic adjustable gastric band, gastric sleeve surgery, and gastric bypass. It is recommended that you talk to your bariatric surgeon before considering any of the aforementioned surgeries. While many opt to have one of these types of weight loss procedures, it oftentimes is not necessary as normal dieting and exercise can effectively treat obesity and obesity related issues.
