Causes of Diarrhea: Food Allergies & Intolerances

Food allergies and intolerances can sometimes cause diarrhea. It is thought that around 2% of adults in the EU have a genuine food allergy, while many more may actually have an intolerance – and the two are very different.

What’s the difference between food allergies & intolerances ?

Food allergies. With a food allergy, your body treats certain foods as a threat and your immune system works to fight against them. Allergic reactions include sneezing, rashes and swellings, and normally occur within minutes of contact with the allergenic food.

Common symptoms of a food allergy :

  • Itchiness or swelling around the mouth or throat
  • Swelling, flushed or itchy skin
  • Wheezing or short breath
  • A running nose & sore or itchy eyes
  • Nausea & vomiting
  • Diarrhea

Food intolerances. A food intolerance doesn’t involve your immune system and reactions are usually stomach related. They tend to develop hours or even days after eating the trigger food. 

Commons symptoms of a food intolerance:

  • Diarrhea
  • Nausea
  • Bloating
  • Abdominal pain

The most common food intolerance is to lactose – a sugar found in milk and other dairy products.

Do you have a food intolerance?

If you have diarrhea or another symptom that might be caused by a food allergy or intolerance, you can try to identify the trigger food by keeping a diary of what you eat every day and when you have the symptom.

If you think you have a food allergy or intolerance, see your doctor for advice.
