The impact I have on my patients is what I enjoy most about being a weight loss surgeon. It is amazing that we can do an operation that not only helps a patient lose weight, but also fixes their diabetes, high blood pressure, and cholesterol, along with giving them a better quality of life. There are a lot of options these days for people who are considering weight loss surgery. It’s important for patients to take into account each institution and what resources they have available. Duke is fully equipped to take care of complex cases in a safe manner. We have a multi-institutional team that’s been around the Triangle the longest and has the most experience. Almost every patient comes back after surgery and we see some of their previous medical conditions go away. That’s a good definition of success. Dr. Portenier is rated as a Distinguished provider by MediFind in Endoscopy. His top areas of expertise are Obesity, Hernia, Short Bowel Syndrome, Gastric Bypass, and Sleeve Gastrectomy.
