Could I have colitis

My mother who is 76 was recently diagnosed with colitis.  My 52 year old sister had ulcerated colitis-she  died a 3 yers ago.
I have been diagnosed with b12 deficency.  I had a history of constipation for about 17 years. Do I have a higher than normal risk of getting colities.?

Vit B12 is absorbed in the last part of the small intesine that is commonly affected in Crohn's disease. Colonoscopy can confirm this.

I had a colonoscopy and the result is I have diverticulosis.  I have not been diagnosed with Crohn's disease but of course I just started on this diagnostic "journey" to discover the root cause of my B12 deficiency.

Causes of low B12:
- No animal food (vegetarians sometimes have low B12)
- Atrophic gastritis (would also cause indigestion, undigested food in the stool)
- Heavy inflammation of the small intestine (Crohn's disea, celiac disease..would cause diarrhea, bloating)
- Small intestinal bacterial overgrowth (SIBO...could cause bloating, diarrhea or constipation, and deficiences of other vitamins (vit A, D, E...) and minerals
