If i had rectal prolapse and it resolved itself, does it mean i still have the condition (disease) or not?

If it does not prolapse any more it is good. Will it recur no body Knows for sure. Pl avoid constipation and forcing and straining during moving your bowels.

Rectal prolapse is a symptom, and what is causing it is not clear from your posting, there is increase pressure in the bowel or decrease supportive tissue at the anus. You should increase fluid, fiber and healthy oil with your food to reduce difficulty in bowel movement however there other conditions that may increase chances of prolapse and if not removed could allow for re- occurrence.
