Our Services

Our experts have the experience to treat you and any adult or senior who walks through our doors here at CHPG Gastroenterology Mercy. We can treat you for a number of conditions impacting your digestive system, including the intestines, liver, stomach, esophagus, and pancreas.

For many patients, their discomfort can be attributed to routine concerns that are easily treated. However, it is important to understand what is really happening with your health. To properly understand the underlying conditions, additional diagnostic testing may be necessary. Routine screenings help to catch diseases and disorders early, creating better outcomes for our patients, as well as reducing unnecessary treatments. Once the symptoms have been identified, it is easier to select the screening technology that will be least invasive and most effective in determining a specific condition and tailored treatment plan.

Our experts can recommend an individually tailored treatment plan for digestive and gastrointestinal issues.
