Medication
Diarrhea can also be a side effect of many medications, in particular, chemotherapy drugs and antibiotics. In most cases, your body might react to the medications themselves or the additives, such as flavorings. Also, these drugs would change the balance of necessary bacteria in the gut, which causes diarrhea and abdominal pain. Thus, make sure to consult your doctor before starting to take a new medication.
