Crohn Disease
Crohn disease is an autoimmune disorder that affects the lining of the digestive tract.
It most commonly causes diarrhea and belly pain due to the inflammation, ulcers and bleeding.
Doctors can use scans and tests like colonoscopy for diagnosis.
While there is no cure for the disease, patients can do certain things in order to improve the symptoms.
This includes cutting down on foods that make symptoms worse, quit smoking and avoiding certain medications.
