We help you treat and manage digestive diseases.


Gastroenterology focuses on diseases of the stomach, intestines, liver and pancreas. Common conditions include irritable bowel syndrome (IBS), inflammatory bowel disease, ulcers, heartburn and colon cancer. These conditions can be painful and negatively impact the day-to-day lives of people they affect.

Ascension treats all types of diseases related to the digestive system. We help patients understand their illness and make the right treatment and lifestyle choices.

Experts Available 24/7

Ascension is the only health care provider in our part of Northeast Wisconsin with all board-certified gastroenterologists available 24 hours a day, seven days a week. (physician bios: Sodhi, Alam and Edison) Our expert doctors, nurses and other medical professionals have experience with a wide range of digestive diseases. Specialty areas include diagnosing and treating inflammatory bowel disease, colon cancer and colon polyps.

Conditions We Treat

Ascension gastroenterologists treat many conditions of the stomach, intestines, liver and pancreas. We use advanced technologies, such as high-definition endoscopy and capsule endoscopy, to make sure our patients receive the best possible diagnosis and treatment. Below are some of our specialty areas.

Colon cancer

Many health experts consider colon cancer highly curable if caught early. Adults over 50 or with a family history of colon cancer should see their doctor every year for a physical. Your doctor may recommend a colonoscopy, an effective tool for spotting cancer and other colon problems.

Reflux and Barrett’s disease

Reflux occurs when stomach contents back up into the esophagus. The acid in this material can cause heartburn symptoms. The United States is experiencing an increase in the number of cases of Barrett’s disease, esophagus damage resulting from years of heartburn and gastroesophageal reflux disease (GERD). Barrett’s disease can be pre-cancerous in some cases, so early detection is important.

Ascension is the only health care provider in the Fox Cities and Oshkosh area to offer narrow band imaging, a specialized high-definition endoscopy technology that can show pre-cancerous cells more clearly than other methods.

We help patients with acid reflux and Barret’s disease find relief through medication and lifestyle changes.

Inflammatory bowel disease (IBD): Crohn’s disease and ulcerative colitis

Crohn’s disease, a form of inflammatory bowel disease (IBD), results when the body’s immune system mistakenly believes harmful substances enter the body. The body tries to rid itself of these substances, leading to chronic inflammation. Inflammation usually affects the intestines.

Ulcerative colitis, another form of inflammatory bowel disease (IBD), is more common that Crohn’s disease. It causes inflammation and sores (ulcers) in the lining of the large intestine.

Over time, inflammatory bowel disease increases the risk of colon cancer, so it’s important for patients to receive regular colonoscopies as recommended by their doctors.

Ascension gastroenterologists not only help diagnose inflammatory bowel disease, they actively participate in each patient’s disease management and follow-up care. Our specialists have more experience with Crohn’s disease and ulcerative colitis than anyone else in the Fox Cities or Oshkosh. We currently treat more than 500 patients with Crohn’s disease in Northeast Wisconsin.

Liver and pancreas disorders

Acension gastroenterologists treat all forms of liver and pancreas disorders. We work closely with UW Health in Madison to refer patients who need liver transplants. Among the specialized treatments Affinity doctors perform is endoscopic retrograde cholingiopancretography (link to ADAM), which can remove stones in the bile ducts that run from the liver and pancreas.

Small intestine disorders

In the past, it was difficult to treat small intestine conditions such as bleeding disorders, Crohn’s disease of the small intestine and aterio-venous malformations because regular endoscopies don’t work. Affinity now offers advanced, non-invasive technology that allows patients to simply swallow a small capsule, which transmits pictures of their bowel to a small computer belt.

Lactose intolerance

Lactose intolerance results when the body doesn’t produce enough of the enzyme lactase, which breaks down milk. Lactose intolerant patients may develop symptoms including nausea, intestinal gas, abdominal cramping and diarrhea after they consume milk products.

Stomach (duodenal) ulcers

Stomach ulcers occur when the balance between stomach acid, enzymes and the stomach’s lining becomes disrupted.

Hiatal hernia

In patients with hiatal hernias, the stomach protrudes through an opening in the diaphragm into the chest. People suffering from hiatal hernia are more likely to develop reflux.

Diverticular disease

Diverticular disease results when the intestinal wall develops abnormal pouches (diverticulum). These pouches can become inflamed, resulting in diverticulitis.
