Greater Houston Gastroenterology

Nizar Charafeddine, MD

Patients of Dr. Nizar Charafeddine benefit from his long experience and familiarity with the unique cases of each of his patients. He has served the Harris and Brazoria counties for the past 19 years and recently joined forces with Greater Houston Gastroenterology. He’s the only physician in the group to service Brazoria County.

“I chose gastroenterology because I understood the field intuitively,” he says. “As an internist, it came naturally to me as a subspecialty.”

Dr. Charafeddine is at the cutting edge of scientific practice of gastroenterology with continuous education and training. He specialize in in-office screening services including lab work, screening for genetic gastrointestinal disorders as well as upper GI endoscopies, video capsule endoscopy (Pillcam) to examine the small intestine, Smart pill for investigation of motility disorders and colonoscopies for colorectal cancer detection and prevention.

“Every patient has a unique set of circumstances and therefore are treated individually,” says Dr. Charafeddine. “It’s an exciting time to be a gastroenterologist,” he says, citing areas where recent advancements have made significant improvements for patients.

The Orbera Weight Loss Solution

Dr. Charafeddine is pleased to have started a multipronged approach to an increasing problem in our society: Obesity. The Orbera intragastric balloon is an interventional, endoscopic, non-surgical procedure to achieve weight loss. The procedure is indicated for qualified patients experiencing unsatisfactory results from diet and exercise. Performed under mild sedation, a soft silicon balloon is placed inside the stomach, through the mouth using an endoscope. The balloon is inflated with saline water to occupy a pre-determined amount of stomach space, giving a feeling of fullness. Along with long-term diet and behavior modification, the procedure has been highly effective in achieving significant weight loss. Dr Charafeddine is the only certified gastroenterologist in Brazoria County to perform this procedure.
