Every ulcerative colitis flare is unique. Some people get mild diarrhea and bloating from time to time. For others, they can be very uncomfortable, with symptoms such as bloody diarrhea, belly pain, nausea, and fever.
Call your doctor if the problem doesn't clear up within 48 hours. Together, you can make a plan so you know exactly what to do next time your symptoms start. Your doctor can also check on your treatment plan or see if you need to take another medicine for a short time to help you get through your discomfort.
