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.

The majority of my practice is focused on treating patients with the disease obesity.

I came to Duke from Nebraska, where I was a medical director for two weight loss surgery programs. I decided to become a weight loss surgeon because it gives me the chance to establish a long-term relationship with my patients. For many patients, weight loss surgery often feels like a fresh start, since they are able to get rid of some of the health problems they may have acquired due to their weight and do certain activities they couldn’t do before. I get a thrill out of being able help patients start this “new life.” My approach to care involves listening to what the patient wants out of the surgery, educating them about various treatment options and performing a full evaluation. Then, I work with the patient to come up with a treatment plan that meets their physical and mental health needs. Dr. Sudan is rated as an Advanced provider by MediFind in Sleeve Gastrectomy.

The majority of my practice focuses on abdominal wall surgery and the repair of ventral, incisional, and inguinal (groin) hernias.

Whether I am repairing a hernia, performing surgery for weight loss, or helping to treat reflux, I will always try to offer a minimally invasive approach first and foremost.
