Prolapses aren't dangerous, just annoying. The only way to stop them is to have another surgery so the surgeon can suture it back in place.
Imagine a sock rolled in on itself once. This is how your stoma is constructed (what you actually see is the inside of your stoma, not he outside). Now, imagine that sock slowly becomes elongated as you pull one end out. This is what happens in a prolapse.
Easy ways to fix it are by rubbing ice on your stoma or sprinkling brown sugar on it (yes, I know, but it's recommended by several stoma nurses and it does work lol).
If the prolapse is very annoying, see your surgeon and ask them to fix it for you.
Good luck.
I have had an ileostomy for 31 years now due to UC.
