Allergy or Intolerance?

Allergies and intolerances explained

Understanding the difference

Can’t decide if you have an allergy or intolerance? Read below and find out the answer for certain. At Sensitivity Check, we help people understand their sensitivities and intolerance (food and non-food) every day.

What’s the difference between an allergy and an intolerance?

The majority of allergies are hereditary and you will most likely be allergic to certain items for life. On the other hand, an intolerance can and does change depending on your diet and lifestyle. The good news though, is you can work with your intolerances to reduce them and even eliminate them.

How do I know if I have an intolerance or sensitivity?

If your body has an inability to digest an item properly, then you have an intolerance to that particular item. This could be either a food intolerance or an environmental factor (a non-food intolerance). Take a look at the two most commons reasons you might have an intolerance to a particular item:

The body is lacking the necessary digestive enzymes(s) for the certain food and therefore cannot digest the item properly or efficiently take the nutrients from it.

Alternatively, are you eating too much of the same thing? Many symptoms are the result of a sensitivity to a particular item. A sensitivity can occur from overconsumption or overexposure of an item.

Understanding possible allergies

How do I detect an allergy?

Allergies are detected by measuring the Immunoglobulin E count (IgE) in the blood, as these are specific blood cells that help to combat allergies. If you have an allergy to a particular food or non-food item, your body will begin to react the moment it comes into contact with it.

Allergy’s present themselves in various ways which severely impact our body. Ranging from localised swelling to a rash or even having difficulty breathing, these allergic reactions can affect our daily routine.

Common allergic reactions can include localised swelling (i.e. of the throat or tongue), a rash, or difficulty breathing. Peanut, shellfish, egg and soya are among some of the most common allergens.

By comparison, an intolerance is not as severe and immediate as an allergy. These symptoms come on gradually; anything from 30 minutes up to a 48 hours later. These symptoms might include headaches, bloating, localised itching or skin irritations such as eczema, excessive mucous production, excessive gas, diarrhoea, and fatigue.

What could I be allergic to?

Peanut, shellfish, egg and soya are among some of the most common food allergens, so be careful and make sure you get tested!

IgG4 food sensitivities are generally less severe than IgE food sensitivities and typical symptoms can include; headaches and nausea, seizures and hyperactivity.

These may occur hours or even days after the offending food has been ingested. The degree and severity of symptoms vary because of the genetic makeup of the individual. IgG4 food sensitivities are generally treated by removing problem foods from the diet and by helping digestion with probiotics.

Not to worry!

However, you may just have an intolerance to a food, meaning if managed carefully, you can still consume the particular product. An intolerance is not as severe and immediate as an allergy.

How can I be sure it is an allergy?

The most common method of diagnosing allergies is with a simple blood test, usually testing the IgE or IgG levels in the blood. Typically, IgE allergies are immediate responses to when a foreign substance that has entered the body.

Where do they come from though? These foreign substances can come from food or can come from inhalation. IgE allergies can cause very serious symptoms like difficulty breathing, swelling, and hives. In even more serious cases, IgE reactions can lead to anaphylactic shock.
