In addition to being proficient in general endoscopic procedures such as upper endoscopy (aka EGD), colonoscopy, flexible sigmoidoscopy, she is also trained in interpreting wireless capsule endoscopy (aka PillCam), wireless SmartPill (the study of the gut’s motility), esophageal manometry and in performance of a non-surgical treatment of hemorrhoids using CRH O’Regan system.

She is Board-certified in both Internal Medicine and Gastroenterology and has been a member of the American College of Gastroenterology since 2008.

Hippocrates, the Father of Modern Medicine, once said, “All disease begins in the gut.” Dr. Anand strongly believes this to be true and has made it her mission to help patients heal their bodies by healing their gut.
