Food intolerance is a condition where intestines find it difficult to digest food. Unlike food allergies, this condition is non-IgE induced hypersensitivity to food and most of the food intolerances are caused due to dairy products, gluten and food containing preservatives and artificial products.

The signs and symptoms of food allergy and food intolerance may overlap. However, it may take longer hours for symptoms of food intolerance to flare up after eating food.

 Signs and Symptoms Of Food Intolerance:

  • Bloated Stomach
  • Migraine
  • Headaches
  • Cough
  • Weakness
  • Stomach cramps
  • Irritable bowel.

Food intolerance may occur due to the absence of a digestive enzyme and it may differ from patient to patient. For example, people with lactose intolerance lack lactase, an enzyme metabolizing milk sugar into small molecules for intestinal absorption. Some food and beverage chemicals, the presence of histamines and salicylates, and toxic effects of naturally occurring chemicals may cause food intolerance in some individuals.

Lactose, wheat, gluten, caffeine, histamine, and artificial sweeteners are commonly known types of food intolerances.

In order to treat food intolerance, doctors' may advise avoiding eating food that is triggering the symptoms.

The only way to prevent the condition is by finding the source that is causing intolerance and adjusting dietary plans accordingly.
