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.

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.

Atrophic gastritis is a chronic condition where the stomach lining thins and loses its ability to produce stomach acid and digestive enzymes. This condition can be caused by long-term H. pylori infection or autoimmune diseases and may increase the risk of stomach cancer. Treatment focuses on addressing the underlying cause and managing symptoms.

Common gastritis symptoms include stomach pain, bloating, nausea, vomiting, and indigestion. Chronic gastritis may cause long-term discomfort, while acute cases can result in sharp pain. Treatment often involves antacids, antibiotics (for bacterial infections), and lifestyle modifications like dietary changes.

Following gastric sleeve surgery, patients adhere to a post-op diet that gradually transitions from liquids to pureed foods, soft foods, and eventually solid meals. High-protein, low-carb meals are recommended to promote healing and support long-term weight loss while avoiding nutrient deficiencies.
