Loose motions or diarrhea are the formation of watery stool within the body. A person experiencing loose motions expels waste that is loose and watery, making it semi-solid to liquid rather than solid.
There are a number of reasons why the body produces semi-solid, almost watery waste. It could range from a simple infection to critical diseases, such as Crohn's. It could be a symptom of certain underlying conditions, such as diabetes or hyperthyroidism. Usually, a person suffering from diarrhea can rectify the problem with over-the-counter medication and by drinking plenty of fluids. However, if the problem persists for more than three days and is accompanied by fever or vomiting, then it is prudent to consult a physician.
