An IBD flare is a return or increase of your disease symptoms. These symptoms can include:
Diarrhea
Increased frequency or urgency of bowel movements
Blood in stool
Nausea
Vomiting
Abdominal pain
Weight loss

Sometimes your doctor will confirm that these symptoms are a flare-up of your IBD with blood work or other testing to make sure that they are not associated with anything else such as irritable bowel syndrome (IBS)or infection.
