According to the Centers for Disease Prevention and Control (CDC), obesity-related health conditions, including heart disease, stroke and type 2 diabetes, are among the leading causes of preventable death. Weight loss -- or bariatric -- surgery has been shown to be an effective and safe method to treat and prevent these conditions. 

Surgical weight loss is designed to help patients achieve their goals for weight loss and improved health through a safe and effective treatment plan. Two types of bariatric surgery are performed by Dr. Patrick Davis with Maury Regional Medical Group Surgery. 


This procedure, often called a gastric bypass, is considered the standard of weight loss surgery. A surgeon creates a small pouch by dividing the top of the stomach from the rest of the stomach. The new pouch is attached to a part of the small intestine known as the Roux limb, forming a Y shape. Food then bypasses the stomach and the upper portion of the small intestine. This bypass reduces the amount of fat and calories that can be absorbed.


This procedure removes approximately 80% of the patient's stomach. The remaining stomach is a pouch that holds considerably less, reducing the amount of food that can be consumed. The surgery also affects hormones in the digestive system that impact hunger, satiety and blood sugar. Short-term studies show the sleeve is comparable to the Roux-en-Y gastric bypass in terms of weight loss and improvement of certain medical conditions. There is also evidence to suggest the sleeve, similar to the gastric bypass, is effective in improving non-insulin dependent type 2 diabetes.


Determining which procedure is right for each individual is a decision made with the patient's goals and long-term results in mind. There are many factors that contribute to which surgery is the best choice. The ultimate decision will involve active discussion between the patient and the surgeon.

Our multidisciplinary team guides patients through the entire process, from preparing for surgery to support following hospital discharge. A monthly Surgical Weight Loss Support Group offers support to patients at all phases of their weight loss journey. Long-term success for weight loss surgery is rooted in active participation and compliance regarding diet, physical activity, vitamin supplementation and other lifestyle choices.
