13 Common Food Intolerance Symptoms | Allergy Test

Experiencing regular discomfort, abnormal bodily reactions to food, or pain could be indicative of food intolerance symptoms. If you are wondering about some of the symptoms of food intolerance and what it actually is, read on to find out.

What is Food Intolerance?

When a digestive system is either irritated by food or is simply incapable of breaking down a particular component in the food’s makeup, the body exhibits signs of food intolerance. Some of the most common intolerances are related to gluten, lactose, and caffeine.

Symptoms Of Food Intolerance:


Bloating, Stomach Aches, And Flatulence

The most common symptoms of food intolerance are bloating, stomach aches, and flatulence. These symptoms are typically experienced by those with more mild intolerances and have an easier time managing them.


Gurgling And Constipation

Gurgling involves your stomach making a lot of noises accompanied by a bubbling sensation and discomfort. Constipation, on the other hand, is when you feel like you need to use the toilet, yet nothing passes.



Diarrhea varies in severity depending on the person and the degree of intolerance. Many will experience a sudden need to go to the toilet. In other, more severe cases, after an extensive toilet trip, the person experiences exhaustion and dehydration.


Vomiting And Nausea

While typically nausea and vomiting occur together, one can experience nausea without actually getting sick. When your digestive system cannot cope with the food you have ingested, nausea, often accompanied by vomiting is experienced in some of the more severe cases.


Headaches, Migraine, And Fatigue

Migraines and headaches are common symptoms of food intolerance, but fatigue is a bit more surprising. However, the body has to work hard to cope with the overexertion of trying to digest foods that it has trouble with, and, as a survival mechanism, experiences fatigue. Headaches are also a common reflective symptom of fatigue.


Skin Rashes And Eczema

While not extremely common, some cases of food intolerance can be followed by skin conditions such as rashes, eczema, and hives. More common as a symptom in children, skin conditions can manifest themselves as a body trying to deal with hard to tolerate food in the digestive system.
