Dr. Ari Nowain – Board Certified Gastroenterologist. Beverly Hills 310-657-4444


As Director of the Center for GI Health, Dr. Nowain, a board-certified gastroenterologist in Beverly Hills, focuses on the care of adult digestive diseases. He specializes in the prevention of gastrointestinal (GI) tract cancer such as esophageal, stomach, and colon cancer. Dr. Nowain and his staff at the Beverly Hills Center for GI Health are committed to providing high quality medical care that is easily accessible to every patient. 

Hemorrhoid Treatments

Dr. Nowain is one of the only GI doctors in Los Angeles offering a new, safe and proven non-surgical treatment option for hemorrhoids. He has performed thousands of procedures, all in a confidential, safe, and comfortable environment. If you are suffering from hemorrhoids, please come in for a consultation to discuss your treatment options.

Colon Cancer Screenings

Although colon cancer is the 2nd leading cause of cancer death in the United States, it is extremely treatable if caught early. So if you are over the age of 50 (or younger with a family history of colon cancer), please come in for a consultation to consider a colonoscopy.

Third Eye® Colonoscopy

Dr. Nowain performs an advanced Third Eye® Colonoscopy, which adds a second camera to the procedure. This allows Dr. Nowain to look behind folds in the colon, where many polyps hide and would otherwise remain undetected if not for this advanced procedure.

Relief from Digestive Problems

If you suffer for digestive issues, a gastroenterologist will use advanced diagnostic testing to figure out the cause of your suffering, and help to improve your quality of life. Often times just a suggestion in a change of your diet or some temporary medication can relieve your symptoms, and other times a simple outpatient upper endoscopy can not only diagnose but also treat the source of your problem.
