Food Intolerance: Causes, types, symptoms, and diagnosis

A food intolerance is difficulty digesting certain foods and having an unpleasant physical reaction to them.

It causes symptoms, such as bloating and stomach pain, which usually come on a few hours after consuming the food.

The number of people who believe they have a food intolerance has risen dramatically over recent years, but it’s hard to know how many people are truly affected. Many people assume they have a food intolerance when the true cause of their symptoms is something else.

Once you have a good idea which foods may be causing your symptoms, you can try excluding them from your diet one at a time and observing the effect this has.

– try cutting out the suspected food from your diet for two to six weeks and see if your symptoms improve
– reintroduce the food to see if symptoms return – you may find you can tolerate a certain level, and you only get symptoms if you have more than this amount.

If you regularly have diarrhoea, bloating, tummy pain or skin rashes but you’re not certain of the cause, see your GP.

Your GP may be able to diagnose the cause from your symptoms and medical history. If necessary, they’ll carry out tests, such as blood tests.

You can also do some research yourself. It may help to read up on other conditions that cause similar symptoms. For example, learn about:

– irritable bowel syndrome
– stress and anxiety disorder
– lactose intolerance
– coeliac disease
– inflammatory bowel disease
– food allergy

Bowels are sensitive organs, and it’s common to have bowel symptoms when you have been ill or feel run down or stressed.

Identifying your food intolerance

Of course, this is not so pleasant for many of us, as if you have an intolerance then you cannot eat everything that other people eat. For many people, it is not so easy to know what kind of intolerance they have in everyday life without a test for food intolerance. Without this test, it is more of a guess than an observation.

Now though, thanks to Test Your Intolerance, this is a thing of the past, as we have a test with which you can see if you are intolerant of certain foods. This can be done by testing just one strand of your hair.
How does a test for food intolerance work?

Hairs can you tell everything. This makes it possible to paint a picture of the person, which makes it ideal for research to see what a particular person really should not eat. So, it is useful to know whether milk is a problem or not. If you know it, then you can adjust your diet accordingly.

Having adjusted your diet, you will hopefully see your symptoms subside. For example, you will be complaining a lot less than you were, as you will no longer be eating a food that you are intolerant to. Dreaming of what this feels like?
