Severe obesity is a chronic disease that is difficult to manage solely by diet and exercise. Bariatric surgery, also called a weight loss procedure, helps patients with severe obesity in losing weight. This surgery is a choice for people who cannot lose weight by other methods or who have severe health issues as a result of their obesity. These procedures modify the digestive system to aid weight loss. They either restrict the amount of food you can eat or limit your ability to absorb nutrients or both. According to recent research, bariatric surgery can also reduce mortality rates in patients with extreme obesity. Patients who combine surgery with a balanced diet and daily workout schedule obtain the best outcomes.
