Loose stools: First, understand that there are two broad types of loose stool: acute and chronic. Acute loose stool is a temporary symptom, arising suddenly and lasting for up to a few weeks. Chronic loose stool, on the other hand, is continuous and does not go away without medical attention. If your have loose stools for over a week, you should probably see a doctor.
