A detailed history regarding when your symptoms started, any associated symptoms with diarrhea like fever, abdominal pain, weight loss etc and the severity and frequency of your diarrhea is important to make a diagnosis. If you are having this for more than 3 months then it is likely that you might have Irritable Bowel syndrome. But like was said before a detailed history and clinical examination along with tests are necessary to make a diagnosis.
