Weight lost refers to the reduction in body weight that is typically achieved through lifestyle changes, medications, or bariatric surgeries like the RNY or gastric band. Weight loss, particularly significant or rapid weight loss, can have dramatic positive effects on a person's overall health, reducing the risk of heart disease, diabetes, and other obesity-related conditions. Successful weight loss usually requires long-term changes to diet, exercise, and behavior.

After lap band surgery, patients must follow a specific diet to maximize the success of the procedure and avoid complications. Immediately post-surgery, a liquid diet is followed by a progression to soft foods and, eventually, solid foods. The diet must be high in protein and low in sugar, with small, frequent meals to avoid overfilling the stomach pouch created by the band.

Weight loss pills include prescription medications like Orlistat (which blocks fat absorption) and over-the-counter supplements marketed to boost metabolism or suppress appetite. While some medications are effective when used correctly, they must be combined with lifestyle changes like diet and exercise for long-term success.

Complications from Vertical Sleeve Gastrectomy can include acid reflux, nausea, vomiting, dehydration, and nutrient deficiencies (especially in iron, calcium, and vitamin B12). In rare cases, more severe complications like leaks from the staple line, infection, or blood clots may occur. Regular follow-ups with healthcare providers help manage these risks.

The term bariatric refers to the branch of medicine focused on the prevention and treatment of obesity and related disorders. Bariatric procedures, such as gastric bypass or sleeve gastrectomy, are designed to help patients achieve significant, long-term weight loss when other methods like diet and exercise have failed.
