That is what I was trying to explain. Sometimes it's hard to tell if you have a virus or a bacterial infection when you have diarrhea. But the body IS trying to flush it out as quickly as possible, without even hardening the stool.
All Immodium does is harden the stool, which may make things worse. My body wasn't able to flush everything out. Whatever bacterial problem I had lingered and built up enough to cause a different problem. Our bodies are really good at self-healing if we don't interfere with it's natural process. You'll know soon enough if you need a doctor for stronger medication.
A bacterial infection in the colon is not common. It usually occurs when a person is on an antibiotic and the antibiotic kills the good, helpful bacteria in the colon, allowing harmful bacteria to take over. Yogurt or acidophilus will help.
When a person has diarrhea due to other problems there's no reason not to stop the loose stools. You will not get better any sooner.
