About Dr. Obioha - Digestive Disease Clinic

As a leading internist and gastroenterologist practicing in Montgomery County and the Baltimore/Washington, D.C., metropolitan area, Dr. Charles A. Obioha, MD, provides expert medical care to patients at the Digestive Disease Clinic offices in Rockville, Bowie, and Silver Spring, Maryland.

Dr. Obioha performs colonoscopies, upper endoscopies, colon cancer screenings, and other procedures to address gastrointestinal disorders, including diverticulosis, gastroesophageal reflux disease (GERD), Helicobacter pylori (H. pylori) infections, hemorrhoids, and nausea and vomiting.

After earning his medical degree at the College of Medicine of the University of Lagos in Nigeria, Dr. Obioha completed a rotating internship at the University of Port Harcourt Teaching Hospital, also in Nigeria.

Then he relocated to the United States and completed an internal medicine residency at the University of Medicine and Dentistry of New Jersey (UMDNJ). After becoming board-certified as an internist, he participated in rigorous fellowship training in gastroenterology and hepatology at UMDNJ and is currently board-eligible in gastroenterology.

Dr. Obioha is passionate about providing preventive medicine, including colon cancer screenings, to his community and encourages everyone over age 45 to schedule screenings as colon cancer doesn’t usually cause noticeable symptoms until it’s reached advanced stages.  

He believes all patients should have access to basic medical care and preventive screenings, including everything from colon screenings and prostate exams to mammography or cervical cancer screenings and Pap tests.
