Allergies: Allergy Types and Information

Updated/Revised Date: 2022-04-12

Synopsis: Information on allergies and allergic reactions to substances, including allergy symptoms, causes, and treatments. Allergens that most frequently cause problems are: pollen, mold, dust, foods, animal dander, insect bites, insect spores, viruses, and bacteria. Some of the most common allergy symptoms known as the seasonal allergies such as hay fever which include itchy watery eyes, runny nose, and sneezing aspects of allergenic symptoms. If the overproduction of the histamines is large enough the surrounding tissue is also damaged resulting in sneezing, a stuffy head, sniffing, stuffed-up head, red and watery eyes.

An allergy is a hypersensitivity disorder of the immune system. Symptoms include red eyes, itchiness, and runny nose, eczema, hives, or an asthma attack. Allergies can play a major role in conditions such as asthma. In some people, severe allergies to environmental or dietary allergens or to medication may result in life-threatening reactions called anaphylaxis. Food allergies and reactions to the venom of stinging insects such as wasps and bees are more often associated with these severe reactions. Not all reactions or intolerances are forms of allergy.

Allergens that most frequently cause problems are: pollen, mold, dust, foods, animal dander, insect bites, insect spores, viruses, and bacteria. Some of the most common allergy symptoms known as the seasonal allergies such as hay fever which include itchy watery eyes, runny nose, and sneezing aspects of allergenic symptoms. Furthermore, other cases of allergy feature more serious symptoms that can be more harmful and troublesome such as absent-mindedness, dizziness, trouble swallowing, nausea, constipation, diarrhea, skin rashes, vertigo, vomiting, and other serious cases of health issues that may spring from how the body deals with the allergen itself.

Normally, though experience, the human body learns to defend itself. That is, by attacking a foreign substance that has invaded and, harming the body by producing antibodies. The best known of these antibodies are called histamines. Occasionally, the immune system mistakenly recognizes a foreign substance, to be harmful, when it is not. This can lead to the overproduction of histamines specially designed to destroy the specific foreign substance.

If the overproduction of the histamines is large enough the surrounding tissue is also damaged resulting in sneezing, a stuffy head, sniffing, stuffed-up head, read and watery eyes. The sinuses as the hay fever tend to affect certain systems of the body or even a skin rash which can be irritating.

What Causes Some Symptoms?

Take for instance Airborne allergy which, however, is the most common form of allergy and tend to feature the most common form of symptom as well. Most of these symptoms are related to the sinuses, like hay fever, tend to impact those systems of the body. Sneezing, a clogged and runny nose, itchiness in the eyes and throat, coughing, postnasal drip, and swollen eyes (a symptom called "conjunctivitis") are all parts of the airborne allergy symptom repertoire.

Why Do These Symptoms Occur?

Most times, the allergic reaction is coupled with a portion of an allergen. In other words, if the allergen is known for entering the lungs, it will likely attack portions of the body related to the lungs and to the breathing. An airborne allergy, hence, is likely to attach itself to the breathing apparatus and will cause coughing or the nose to run because of the way it affects the system. A person with Allergies is burdened with an overprotective immune system and is forever on guard against everyday things that don't usually bother the rest of us. It might be a cute affectionate kitten, a patch of green grass, a slice of fresh garden tomato.

Some of us can roll in poison ivy and come out without any problems, whilst others can merely brush up against a few leaves of the stuff, and they are scratching for weeks. In most cases, allergies are more annoying than are infirmity. To the extreme allergy sufferers, life can be pure misery or even death.

Main Types of Allergic Reactions

Food, mold, animal dander, pollen, or dust can cause an immediate reaction to an allergy attack. When your body responds to the invasion, the body release histamine from the irritated area such as the skin, nasal and bronchial areas. Allergens combine with healthy cells in your body, which attacks the healthy cells; this is common in upper gastrointestinal attack.

Allergens invade the immune system and can cause injury to cells though out the body. T-cells become activated and result in an inflammation of the affected area. This is exemplified by a rash caused by poison ivy. Instead of the antibodies binding to the cell components as they do in type 2 allergies, the antibodies bind to the receptors on the surface of the cells.

We all carry a heavy load of various stress factors that slowly wear out our immune systems, over the years, making us more susceptible to allergy attacks. We are exposed to many more environmental pollutants and industrial toxins. No matter what type of allergy you are suffering from, there is a good chance that you can find relief from it. You can fight allergies with vitamins and over the counter products. Common Vitamins and over the counter products can help with Allergies such as vitamin A, vitamin B, vitamin C, vitamin E, Vitamin B5, Glucosamine, Antioxidants, Allergy Aid, and Quercetin.

How are Allergy Symptoms Cured?

An allergy symptom can be cured in several ways, depending on the actual system it affects and how drastically the body is affected. Many people can simply take, for example, an antihistamine for a hay fever type allergy and go about their day, while others simply will not respond to the antihistamine. It is really essential for the matter of the biological makeup of the allergy sufferer in terms of how they react to certain medications and how much medication is needed to cure the allergy symptom.

Allergy Facts and Statistics

Above statistics from U.S. CDC. According to Allergy UK, one in four people in the UK suffers from an allergy at some point in their lives. The numbers are increasing every year, and up to half of those affected are children.
