An allergic reaction to peanuts can also manifest in diarrhea. A food intolerance to peanut butter, however, is going to be different from a food allergy in that your symptoms can be more than just indigestion. Peanut allergies involve an immune system response.
One of the more common food allergies out there, peanut allergies manifest in hives, redness, or swelling of the skin, itching in the mouth and throat, stomach pain, nausea, vomiting, and diarrhea, wheezing and shortness of breath, a runny nose, and feeling like your throat is closing up.
In severe allergy cases, a person can go into a state of anaphylaxis, an immune system reaction that includes a drop in blood pressure, hampered breathing, constricted airways, and dizziness. While food allergies are common when you’re a kid, they can develop later in life as well. If you’re allergic to peanuts, you should watch out for dishes or store-bought goods that may contain peanuts as an ingredient and even coming into contact with them via inhalation. Seek healthcare attention if you think your diarrhea is related to an allergy, particularly if it is accompanied by other symptoms. Anaphylaxis can be life-threatening.
