Our Procedures Treating Stomach Problems and GI Diseases

The Board Certified gastroenterologists at Digestive Health Associates (DHA) perform a variety of procedures to address internal ailments for our patients in Houston. Our specialized doctors treat stomach problems, digestive disorders, and other diseases affecting the GI tract.

Our practice is unique. Three of our in-house doctors (Dr. J. George Sun, Dr. Cristian Dominguez, and Dr. Joseph Krill) are interventional gastroenterologists capable of performing ERCP and EUS procedures. Additionally, Dr. Joseph Krill is highly trained in endoscopic bariatric procedures. In addition to the usual endoscopic procedures Dr. Ramesh also interprets Esophageal Motility Studies.

After reviewing your condition and diagnosing the cause of your condition, we will schedule a procedure to address the ailment. We perform the vast majority of procedures off-site at the Memorial Endoscopy Center. (We will inform you of any procedures that we perform in-house at the DHA office.)

After your procedure, we will continue to provide follow-up care and health management services to ensure that you are successful on the path to recovery. Consider the procedures that we offer for our patients.

What Our Patients are Saying

“My doctor referred me to Dr. Ramesh when I needed a colonoscopy. Dr. Ramesh was attentive, thorough, and friendly. I felt he was extremely knowledgeable with his area of medical expertise. Therefore, I feel confident referring Dr. Ramesh as a gastroenterologist.”


“My dad had his endoscopy done here with Dr. Ramesh. We met him first at the DHA office in the Memorial City Medical Tower. He was amazing. Super detailed when he explained what the next steps were to help my dad out. He answered all my questions and concerns. Then, for the procedure, the staff at Memorial Endoscopy Center were extremely helpful. My dad only speaks and understands Spanish and he has nothing but great things to say about all the super sweet medical staff that helped him out. Everything was super quick and no issues whatsoever. I 100% recommend this location.”
