Glenn Marshak, M.D. Internist

Dr. Marshak graduated from Chicago Medical School, Chicago, Illinois, in 1992.

He says many patients tell him their back and joint pain diminishes and sometimes disappears after surgery.

"Often it is the excess weight that is causing the pain in the first place. When their weight begins to drop, the source of the pain begins to fade."
