What Can Cause Canker Sores And Abdominal Pain?

I am having lots of canker sores. I have four in my mouth now. I am under the care of a wonderful GI doctor. I have had endo/colon, blood tests & small bowel series. I am curious to know what could be causing my mouth sores. they used to only come one at a time. Now I can have up to 3 or 4 at the same time. I know they are an autoimmune response. I am low in B12 and have abdominal pain. Do you know of a possible cause? I am waiting for the results of my small bowel.

Hello!
I had gone through your query and understand your concern.

The exact cause of most canker sores is unknown.
- Stress or tissue injury is thought to be the cause of simple canker sores.

Some cases of complex canker sores are caused by an underlying health condition, such as:
-an impaired immune system;
-nutritional problems, such as vitamin B-12, zinc, folic acid, or iron deficiency; gastrointestinal tract disease, such as Celiac disease and Crohn's disease.

Pain from a canker sore generally lessens in a few days and the sores usually heal without treatment in about a week or two.
If sores are large, painful, or persistent, your dentist may prescribe an antimicrobial mouth rinse, a corticosteroid ointment, or a prescription or over-the-counter solution to reduce the pain and irritation.

Hope it helped.
Take care
