I saw Dr Ayyar about 3 weeks ago. I was a new patient as my previous Dr. had retired. He is a wonderful doctor who took his time explaining everything to me. I feel blessed to have him as my new gastroenterologist. skp

About Us

An optimal way to detect and prevent cancer is to undergo a colonoscopy before cancer grows to a critical stage. Over 95 percent of precancerous polyps are identified during a colonoscopy and are removed during the procedure. Tissue samples from the polyps are sent to pathology to determine any signs of cancer. A colonoscopy is a preventative measure that safeguards your GI health by eliminating any polyps before they progress to a severe stage. A colonoscopy is a gold standard for both the prevention and detection of colorectal cancer.

Crohn’s disease and ulcerative colitis are among the most common types of Inflammatory Bowel Diseases (IBD). Many Americans are affected, with around 1.6 million currently impacted by these diseases. IBD is a chronic condition that’s typically diagnosed in patients before the age of 35. As a chronic condition, it can be treated but not completely cured. There are approximately 70,000 new cases in children and adults detected each year.
