Digestive System Relief

Make an Appointment

Doctors in gastroenterology focus on the study, prevention, diagnosis, and treatment of the digestive system, or gastrointestinal tract (GI). Related parts of the body include the mouth, throat, esophagus, stomach, small intestine1, large intestine2, and anus.

For both men and women, the third most common cancer is colorectal cancer, affecting one in five (20 percent) of adults3. Screening, which sometimes includes colonoscopy, is still the best colorectal cancer prevention.

Occasional indigestion, cramping or abdominal pain, and acid reflux are normal and relatively common. Persistent or regular discomfort like this isn’t normal, however, and several conditions that start with these symptoms can become severe. Only a physician can tell the difference. Talk with a gastroenterologist who can determine whether you need medical treatment.

Some of these serious, long-term conditions may improve if you change your diet – not just what you eat, but also when you eat and how much. If you have, or think you have, Crohn’s disease, celiac disease, diverticulitis, diverticulosis, gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), or colitis set up a consultation to review your diet and create a management plan with one of our team members.
