After more than 20 years of rampant bleeding and severe anemia, I resolved my problem a couple of weeks ago.
I had cut out fried foods, processed foods, dairy, spicy foods and all kinds of other things. Doing that and eating tons of bananas and pineapple helped a lot, but I could never get rid of the bleeding. And if I ate one wrong thing, it was back to 45 minutes on the toilet three times a day for a week.
Then I tried Clostridium butyricum. In three days, the bleeding disappeared like a dream.
I've had two relapses since, and I have switched from C. butyricum to kimchi, which I find works just as well.
I've also heard of people having good luck with natto.
