Recently had another colonoscopy, he is extremely personable and easy to speak with. He is my new gastroenterologist as my doctor of over 20 years is now retired.

My visit with Dr. Oh was seamless in its' scheduling and coordination of care I received from office personnel. Dr. Oh is very easy to speak to and he understands that I am interested in my own health. So, once the doctor listened carefully, he prescribed a course of treatment to include a colonoscopy. Since I have experienced problems in the past with the removal of a sizeable polyp and periods of constipation which included an episode of bowel impact, the colonoscopy at this point was a good idea. I told the doctor that I really wanted to know what was causing me to have constipation. Since I am a major fan of large doses of fruits & vegetables, a surgeon at Hackensack University Medical Center in Hackensack stated that I was eating too much of these. I drink at least 2 gallons of water daily along with other liquids and eat sufficient (albeit possibly too much) fiber, it is a puzzle that needs to be solved. Hopefully, the Colonoscopy will disclose why I am having problems.
