Overview
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.

Duke Spine Center - Clinic 1B/1C
I am a neurosurgeon and researcher who focuses on surgical solutions for movement disorders and pain due to cancer, prior nerve injury, stroke, failed back surgery, limb amputation, trigeminal neuralgia and other causes. I have always been fascinated by how the brain and spinal cord works, converting a thought in your mind to a physical action or feeling. As a neurosurgeon, I get to treat people who have problems with this process. Every day, I get to help patients make dramatic improvements in their quality of life, which is greatly rewarding. At Duke, we’re lucky to have access to the latest technologies and world-class research. Our technology allows us to perform surgeries in the least invasive, most precise ways possible. When I am not working, I enjoy spending time with my wife and three young boys. Dr. Lad is rated as a Distinguished provider by MediFind in the treatment of Thrombophlebitis.
