Surgical Weight Loss

If you’re considering bariatric surgery to help you achieve a healthy weight, you’ve come to the right place. Our bariatric surgeons, O. Raphael Nwanguma, M.D., FACS, and Roshni Venugopal, M.D., are experienced and compassionate. Medical Center Surgical Weight Loss Program has achieved accreditation as a Center of Excellence in Metabolic and Bariatric Surgery by Surgical Review Corporation (SRC). Dr. Nwanguma has been recognized by the SRC with the Master Surgeon in Metabolic and Bariatric Surgery Accreditation.

Med Center Health’s team approach helps you make a smart choice — and gives you the best opportunity for success. We start with an initial consultation that includes a complete history, physical exam, psychological evaluation and nutritional analysis. We’ll explore all your options (not just the surgical ones), discuss exercise and lifestyle changes to improve your overall health, and give you the tools and information you need to make a smart decision.

To help you understand how your eating habits will affect your outcome — both before and after weight loss surgery — a registered dietitian will discuss an improved nutrition plan. And, because weight loss surgery represents more than just a physical change, a counselor will discuss the emotional challenges you may experience during this life-changing journey. Before and after surgery, support group meetings are available to connect you with others who share similar weight-loss challenges.

If you think surgical weight loss may be right for you, start by completing and returning our Patient Intake Packet. For more information, call (270) 796-6333.

  • Gastric Sleeve: After removing the outer 85 percent of the stomach, the stomach is converted into a thin, narrow “sleeve” which holds less food, resulting in less appetite. With this procedure, weight loss is rapid for most patients.
  • Laparoscopic Roux-en-Y Gastric Bypass: This procedure divides the stomach to make a small reservoir pouch for food at the upper end of the stomach. The pouch, which has a capacity for about one ounce of food, is connected to the upper small intestine. Therefore, food bypasses the larger portion of the stomach. Patients experience a decreased appetite. Rapid weight loss occurs initially and stabilizes over time.
