Diarrhea and Food Allergy

Allergic reaction is our body’s way of responding to substances that invades our physical condition. When it comes to food, allergic reactions take place when the food is ingested or, in people with severe allergies, when the food is being cooked or served nearby. A body of a person with allergies reacts even a very small amount of food was ingested. The common reactions are skin rashes, itchy sensations, coughing, and diarrhea or vomiting. In kids and toddlers, the digestive symptoms are often the easiest to identify.

Our body reacts to and eliminates an allergen by stomach pain, vomiting and diarrhea. These symptoms can begin rapidly and can go on until the immune system reaction slows down or is stopped by means of medical treatment. Recurring episodes of loose stool with or without vomiting may lead to fatigue, weight loss, and dehydration.


Diarrhea and food allergy reaction can be treated. The treatment is based on the severity of the reaction. It does not emergency epinephrine, or Epi-Pen, injection; however, antihistamines may be given to stop mild allergic reactions. An effective treatment for diarrhea focuses on increasing fluid intake to prevent dehydration. If the diarrhea involves blood or is associated with vomiting that may lead to dehydration, you should go to your doctor immediately.

You can avoid food allergies by preventing contact with the allergy-causing food. You may consider using a new type of therapy known as oral immunotherapy or OIT. This method focuses on preventing food or environmental allergic reactions by gradually training your immune system to get used to the allergen in the body. In addition, results of OIT use have been good in early attempts in people who are allergic to peanut; this technique is not commonly available and is still in early research stages.
