It increases the risk of developing severe medical requirements, including high blood pressure, type 2 diabetes, heart disease, and certain cancers. Additionally, obesity can lead to reduced mobility, joint problems, sleep apnea, and a lower quality of life. Understanding the profound health risks associated with obesity is the first step in considering weight loss surgery as a potential solution.

Weight loss or bariatric surgery is a medical intervention designed to help individuals with severe obesity achieve significant and sustainable weight loss. These surgeries alter the digestive system, reducing food intake and weight loss.

Common Types of Weight Loss Surgery
Several weight loss surgery options are available, each with its unique approach and mechanisms for achieving weight loss. Understanding the differences between these procedures is crucial for making an informed decision.
- Gastric Bypass (Roux-en-Y): This procedure includes creating a little stomach pouch and diversifying the small intestine. It restricts food intake and lowers calorie absorption.
- Sleeve Gastrectomy: In this surgery, a portion of the stomach is removed, leaving a shorter, banana-shaped stomach. It limits food intake and lessens hunger hormones.
- Adjustable Gastric Banding (Lap-Band): This procedure involves placing an adaptable band around the upper part of the stomach to create a small pouch. It limits food intake by inducing a feeling of fullness.
- Biliopancreatic Diversion with Duodenal Switch (BPD/DS): A more complex surgery, BPD/DS, involves eliminating a large portion of the stomach and diverting the small intestine. It limits food intake and reduces calorie absorption, leading to substantial weight loss.
Eligibility and Candidacy
Weight loss surgery is not a one-size-fits-all solution. Eligibility criteria typically consider BMI, obesity-related health conditions, and previous weight loss attempts. However, it’s essential to emphasize that eligibility for surgery is determined through a comprehensive evaluation conducted by a healthcare team, including a surgeon, dietitian, and mental health professional.
