If you’re living with ulcerative colitis (UC), mouth problems can start even before more typical symptoms like cramps and diarrhea. Some mouth sores are short-lived and are more of a nuisance. Others can affect your ability to talk or eat.
Diarrhea and cramps are among the most well-known UC symptoms because UC primarily affects the colon and rectum. They stem from inflammation and sores called ulcers in the intestines.

UC swelling and sores can appear anywhere in your GI tract, including in your mouth, but UC-related sores are not typical in other parts of the GI tract outside the colon and rectum.

Canker sores (aphthous stomatitis) are painful white or yellow spots that form inside the mouth around the gums, lips, or tongue. You’re more likely to get canker sores during ulcerative colitis flare-ups. They typically heal once you treat the flare.
In addition, pyodermatitis-pyostomatitis vegetans is a rare condition that mainly affects people with ulcerative colitis. Symptoms include a rash in skin folds like the armpits and groin. You may also experience pus-filled sores inside the mouth and throat.

- loperamide (Diamode)
- metronidazole (Flagyl)
Some people with ulcerative colitis report a strange metallic or acidic taste in their mouth. This symptom is more
This severe inflammatory disease affects the entire colon and is usually caused by ulcerative colitis.
Taste changes may stem from a B12 vitamin deficiency. Experiencing a metallic taste can be a side effect of the drugs sulfasalazine, azathioprine, and metronidazole (Flagyl).
Bad breath (halitosis) often happens if you’ve let your oral hygiene habits lapse. In ulcerative colitis, bad breath
Saliva washes away dead cells and bacteria in your mouth. Those cells build up when your mouth is dry. This can leave you with an unpleasant breath aroma.
Some people with ulcerative colitis who experience bad breath may have an increased level of sulfate-reducing bacteria in the colon. This leads to higher amounts of the gas hydrogen sulfide, causing bad breath.

The cause in people with ulcerative colitis is often a vitamin B12 or iron deficiency. Long-term treatment with corticosteroid drugs can also result in this symptom.
The first step to relieving ulcerative colitis mouth sores and other mouth problems is reducing inflammation in your gastrointestinal tract and implementing a treatment plan to manage your ulcerative colitis.
Medications like aminosalicylates (5-ASAs), corticosteroids, immunomodulators, and biologics calm the overactive immune system response that causes inflammation and sores. Your doctor can help you find the right drug or drugs to help manage your ulcerative colitis.

Talk with your doctor if you think a medication you take for ulcerative colitis could be causing these symptoms. Your doctor may recommend alternative treatments less likely to cause mouth sores or suggest other ways to manage this side effect.
Besides ulcerative colitis and medications, causes of oral problems like sores include:
- mouth trauma
- a connective tissue disease like scleroderma
- certain rare congenital disorders
- viral or bacterial infections such as herpes simplex and oral lichen planus
- Behcet’s disease
- erythema multiforme (EM)
- Sjögren disease
