Can you tell me how i can stop loose motion (diarrhoea)?

Determine cause: If a patient has diarrhea, the important thing is to determine the cause - that way the treatment can be best directed. Food poisoning or 'gastroenteritis' is a common cause. In those cases, the illness is usually self limited and goes away within a few days. If it's something more, like a malabsorption syndrome, then you really need the help of a GI specialist or someone who can evaluate properly
