Blood type = Disease susceptibility??

I borrowed this from a small FB group and was wondering what the results are on a larger scale:

"I'm conducting an informal survey. I recently read somewhere that your blood type can make you more susceptible to certain diseases. I'm interested to see if this is the case. Please respond with what disease you had that led to the ostomy and your blood type. Let's see if the studies I've read are true."

I'll start:

ulcerative colitis, B+.

Don't answer if you don't want to. Merely just for curiosity/fun. I wasn't expecting a pattern. The same post is over on the UC board, and there does not seem to be any pattern.

Sorry, I read that book about blood types way back when....it was all the rage..but, no science to prove anything...

As far as blood type, I"m A+ .....top quality all around! lol!
