10 Diarrhea Causes
Reviewed: Dr. Mera
Cause #2: Food Allergy
The most common food allergies are milk, egg, peanut and soy allergies. All of these and many other food allergies usually cause diarrhea to occur whenever the allergic person is exposed to allergen.
If your diarrhea is caused by a food allergy, the first symptoms will develop within minutes to hours after the exposure. It will take around 24 hours for the symptoms to pass. Usually, the watery diarrhea is self-limiting (goes away on its own). Food allergies can be life threatening conditions due to airway obstruction, so patients should seek medical attention as soon as possible after exposure.
