It doesn’t happen to most people who have UC. Less than 10% of people with it get fulminant colitis, usually during their first attack of symptoms. The whole lining of the colon becomes inflamed, causing severe symptoms like bloody diarrhea and belly pain.
Fulminant colitis is a medical emergency. You'll need to go to a hospital right away for treatment with medicine, and possibly surgery.
Fulminant colitis inflames and damages the walls of the colon. Extreme swelling in the colon walls can cause a condition called ileus. This is when the walls of your intestines widen and they can't squeeze well enough to push digested food through.
As ileus gets worse, the colon may become very wide. Gas and poop can get trapped inside the intestine because they can't move through. This is called toxic megacolon. It's a life-threatening emergency. Sometimes, people get severe bleeding or a body-wide infection called sepsis. Another possible complication is a tear or hole called a perforation in the colon.
You're more likely to get fulminant colitis if you have an infection with bacteria or a virus. Your risk is also higher if you take corticosteroids or other medicines that suppress your immune system.
Fulminant colitis causes symptoms like these:
Fulminant colitis can be hard to diagnose because it can look like a flare of ulcerative colitis or Crohn's disease. Your doctor may have to do a few tests to find out what’s going on. It's important to diagnose this condition correctly, so you can get started on the right treatment.
Tests to diagnose fulminant colitis include:
Treatment for fulminant colitis happens in a hospital where doctors and nurses can monitor you closely. Your medical team will check your blood pressure and other vital signs often.
Treatment for fulminant colitis starts with corticosteroid medicines, which you get through an IV. If steroids don't help you feel better, your doctor may give you cyclosporine or the biologic drug infliximab (Remicade) to calm your immune system.
You might need surgery if medicines don't help, or if you have:
- A hole (perforation) in the wall of your colon
- Toxic megacolon
- Severe bleeding
Colectomy is surgery to treat fulminant colitis. The surgeon removes the damaged part of your colon and makes a pouch inside your body to hold stool, so that you can poop normally.
Fulminant colitis may be hard to prevent because it often happens during the first attack of UC symptoms.
Once you are diagnosed with UC, follow the treatment plan your doctor prescribes to prevent damage to your colon. Medicines for UC bring down inflammation and give your colon a chance to heal. You may take more than one medicine at a time.
Fulminant colitis can lead to toxic megacolon and a hole in the colon, which are emergencies. To have the best outcome and avoid these complications, stick to the UC treatment plan your doctor prescribed.
