Welcome to GI Alliance of Illinois. Our patient-centric focus will ensure that your care and comfort will always be our top priority. Our team of skilled GI specialists assists patients with achieving their optimal GI health through diagnosis, treatment, and management of a variety of GI conditions that range from acid reflux, bloating, and constipation to Inflammatory Bowel Disease, colon cancer, liver disease, and much more.

About Us

When it comes to colon cancer, it is always best to be proactive! The best way to prevent it and detect it early is to schedule a colonoscopy screening. A colonoscopy is also a great tool for diagnosing other bothersome symptoms such as abdominal pain, rectal bleeding, chronic diarrhea, and more. If you are 45 or over, at risk for colon cancer, or have a family history of colon cancer, a colonoscopy is a simple and easy 15 – 30 minute procedure to help you stay on top of your colon health.

Inflammatory Bowel Disease is the chronic inflammation of the GI tract. The most common forms of IBD are Crohn's disease and ulcerative colitis, which affect approximately 1.6 million Americans, with new cases being diagnosed every year. Some risk factors include age and whether you smoke; however, you are at a heightened risk if you have a family history, as IBD can be genetic. Although IBD does not have a cure, there are treatment options available to manage this chronic condition and its symptoms.
