What is exactly an allergy?

It is not good news when someone tells you that you’re allergic to something. 

Unfortunately, a great number of individuals are all too familiar with allergies. Many symptoms are uncomfortable, including itchy eyes, a drippy nose, and even a skin rash. However, a more precise medical explanation perhaps better, since this is the initial part of diagnosing and dealing with the proper condition. 

How we define allergy is based on a sizable amount of information. It’s an overly sensitive response to allergens that leads to an allergic response. However, this explanation just goes in a circle. How do you define allergen? How do you define an allergic response? Why don’t we elaborate. 

In some people, being exposed to certain allergens leads to manufacture of IgE by white blood cells. Within the system, that substance next latches on to mast cells or basophils, which are also leucocytes. These consequently emit histamines, prostaglandins and yet different compounds. When they are produced in excess, this leads to the symptoms you actually experience. 

The response to all this activity differs in each person. Different people will experience varying types of reactions. Certain individuals suffer from minor to serious asthma. Another people will get a rash on their skin, like eczema. Others experience typical signs like watery eyes and sniffles. Reactions including urticaria, pollinosis or potential anaphylaxis can take place. 

Thus, allergens are simply substances that produce allergic responses. Unfortunately, this is a pretty inclusive term. 

Familiar atmospheric elements like pollen elicit reactions in countless individuals. Animal dander and dust mites affect many people. Bee stings or wasp stings can cause an allergic reaction in some people. Sometimes certain foods, such as milk, peanuts, or shellfish, cause people to have allergic reactions when they eat these foods. 

A genetic factor called atopy is involved frequently. However, allergies may be acquired with time as you’re exposed repeatedly or for a long period. 

A tiny quantity of dust, for instance, could elicit no response from someone who’s otherwise sensitive. However, eventually more dust mites in dust gain access to sinuses through inhaling, releasing greater amounts of material. Ultimately this can cause the recognized sign of rhinitis or sniffles linked with this certain allergy. 

Likewise, conjunctivitis or inflammation of the eyelid’s membranes, is a frequent result of being exposed to atmospheric elements. This is a common sign of hay fever, hives, and different allergic responses which, while unpleasant, are not typically a real danger. 

Even more drastic responses can, and in fact nearly always do, occur in certain instances. Bee stings cause some hypersensitive people to have a severe allergic reaction. Reactions such as severe respiratory problems, circulation problems, or even death can be the result of anaphylactic shock from one single sting. The onset may be sudden, involving significant drop in blood pressure, difficulty with respiration, and serious dermatological rash. Medications such as epinephrin or cortisone can be used to quickly and easily alleviate allergies. 

Exams for allergies, as well as treatment, have seen advances in recent decades. There have been great advances in medicine to help people find quick allergy relief , although some of the procedures may still be unpleasant, and some of the treatments may not completely work. Total cures are hard to come by, however alleviation of symptoms is often effective and enduring. 

This is really terrific news for a great number of sufferers.
