Whatever it is that helps your chronic constipation, keep it up! Do what ever it takes to expel the waste. If you don't, your bottom will literally fall outside of your rectum! Happened to me and it was freaky! I had to have surgery for a rectal prolapse and it was no pic-a-nic! Five years later, the darn thing is coming back--my advice? Don't strain, the doctor told me not to linger! How on earth does one not linger when they have to poop? Doubling over in pain and not being able to produce, very unfun!
Clearly, I need a better diet; one to include fruits and veggies, not chocolate and potato chips!
