Bowel obstruction at 15 years old, is that possible?? (PLEASE READ)?

Was it one of those disposable Fleet enemas? They are not the best choice if you are really backed up. You really need more solution than they contain. What you might try is take the bottle and refill it with warm water. Do this at least 4 times or more and then hold for a few minutes before expelling. This is much more comfortable than using the solution that comes in those bottles.
