Bariatric surgery is a medical procedure performed on individuals who are severely obese and have been unable to lose weight through other means such as diet and exercise. The aim of bariatric surgery is to reduce the size of the stomach or restrict the amount of food that can be consumed, leading to weight loss and improvements in overall health. There are several types of bariatric surgery procedures, including gastric bypass, sleeve gastrectomy, and gastric banding. These procedures can lead to significant weight loss, improved quality of life, and reductions in obesity-related health conditions such as diabetes, high blood pressure, and sleep apnea. Bariatric surgery is considered a last resort option for individuals with a body mass index (BMI) of 40 or higher, or a BMI of 35 or higher with obesity-related health issues. It is important for individuals considering bariatric surgery to consult with a healthcare provider to determine if they are a suitable candidate for the procedure and to understand the potential risks and benefits.
