Obesity is a worry for many today and while diet and exercise are effective mediums to reduce extra weight, sometimes it requires more than just these factors to shed of those heavy pounds. Obesity is a condition where a person’s Body Mass Index (BMI) – relation of the weight in correspondence of height – is 30 or more. Obesity also has levels: class 1 obesity is up to 35 BMI level, class 2 obesity is up to 40 BMI levels, while class 3 obesity refers to a BMI of 40 or more. No matter the class, obesity is always undesirable and hence, methods other than exercise and diet are required to lose those extra kilos. One of the highly desirable and sought after methods is a Bariatric Surgery.
A bariatric surgery is a metabolic surgery that reduces the fat in the body by making changes to the digestive system. A general bariatric surgery helps a person lose 50% of the excess weigh during the first 6 months. The surgery makes the stomach smaller and limits the amount of food one can eat at one time by making you feel fuller earlier. More so, the surgery may involve changes in the small intestine so that there is limited absorption of calories and nutrients form food and beverages. A bariatric surgery may include one of these techniques or could include both, depending on case to case.
As mentioned earlier, a bariatric surgery is opted where diet and exercise are no longer effective and the excess weight has started to cause adverse health effects such as high blood pressure, heart problems, Gastroesophageal reflux disease, severe sleep apnea, diabetes, stroke, etc. However, not everyone qualifies for a bariatric surgery and there is an in-depth screening before the doctors consider you fit for the surgery. A bariatric surgery can be one of the following types:
Gastric bypass surgery: where the stomach is divided into a smaller size to reduce food intake
Gastric band surgery: where a band is places around the stomach to reduce the food consumption. This is a reversible process.
Patrial gastrectomy: also known as sleeve gastrectomy, this procedure removes the stomach replacing it with a small portion plate which results in reduction of appetite due to suppressing of hormone ghrelin.
No matter the type of bariatric surgery, it is vital to understand the procedure, know the facts and risks associated with it.
