More Info on Common Digestive Issues and Concerns

We understand that it can be embarrassing to talk about things like gas, bloating, constipation, diarrhea and hemorrhoids. These are common problems for many people. In most cases, it’s not serious. However, if it causes you significant discomfort and you can’t find relief from a change in diet or an over-the-counter medication, you should mention it to your doctor. We recommend the American College of Gastroenterology website for answers to some of your concerns.

Meet our Gastroenterologists

Our gastroenterologists have extensive training in diseases of the digestive tract and liver. In addition to medical school, they must complete a three-year internal medicine residency and then undergo additional specialized training with a two- or three-year fellowship in gastroenterology. With this intense preparation, they are qualified to answer any questions you may have and prescribe the best course of treatment for a wide variety of conditions.

Riverside Medical Clinic strives to provide patients with world-class health care and make it convenient to see your doctor. We also believe you deserve great options for your family. That’s why we have top-quality providers available at locations close to your home and workplace. If you are having digestive issues reach out to your Family Medicine or Internal Medicine provider.
