What is the difference between allergies and sensitivities?

In my last post I discussed allergies and self care. Today I want to talk about the difference between allergies and sensitivities.

In most cases the terms “allergies” and “sensitivities” are used to mean the same thing. It is important to note though that many sensitivities are not true allergies.

Let's look at sensitivities first. The term “sensitivity” is general in nature and includes reactions that do not affect the immune system. If your immune system is not affected you do not have a true allergy.

The bottom line is that sensitivities are usually reactions for which the cause has yet to be determined.

Some non-allergic types of sensitivity may also be referred to as intolerances. These intolerances may be caused by toxins, enzyme inadequacies; drug-like chemical reactions and may possibly have psychological associations.

One of the best (and widely recognized) samples of an intolerance is a lactose intolerance.

Common symptoms of allergies include itchy, watery eyes; sneezing; headache; fatigue; postnasal drip; runny, stuffy, or itchy nose; sore throat and an itchy feeling in the mouth or throat. You may also experience dark circles under your eyes; abdominal pain; diarrhea; and the appearance of an itchy, red skin rash.

Most allergies are not life threatening but some are. The most common life-threatening allergic reaction come from and allergy to peanuts, nuts, shellfish, and some drugs. If you ever have trouble breathing and difficulty swallowing seek immediate medical assistance.

Unfortunately detecting allergies and other sensitivities and then eliminating or reducing your exposure to the root of the problem is often a time-consuming process. It is always wise to consult an allergy or food sensitivity specialist.
