The most common cause could be due to gastroenteritis due to a viral or bacterial infection of the gut. Most of the infections are usually viral in origin and no treatment is needed. I would advise you to take plenty of water and small frequent meals.
If the symptoms don`t improve even after these measures, you may see your doctor who might order blood test, stool culture to make a definite diagnosis.
