The Variety of Allergy Symptoms
In any group of 4 individuals, 2 are most likely to suffer from allergic diseases. Allergies are usually experienced by people who are atopic or those prone to allergies. If foreign bodies, commonly called allergens, come in to contact with your immune system and it does not react appropriately, then you might be someone likely to succumb to an allergic disease. Allergy symptoms vary from the mildest to the most extreme types.
Here are few allergy symptoms that can occur in the different parts of the body. When experiencing nose allergy, most probably symptoms are rhinitis, nasal discharges, sinusitis which could be chronic and sneezing. Allergy symptoms of the eyes are discomfort caused by drying, burning sensation, itching and there may also be some discharge. Skin allergies will have symptoms of angioedema, dermatitis and hives.
Babies and children usually encounter allergies in the form of eczema or atopic dermatitis. Symptoms displayed include flaking of skins and itching, which may result in slight blisters that subsequently burst if scratched continually over a period of time. If untreated this could lead to allergic rhinitis and asthma. It has been reported that food and environment are two vital factors which could contribute to this type of allergy in children.
Asthma is the most common allergy which can start during young adulthood and persist throughout the life of a person. Allergic symptoms include coughing which could be dry and choppy and which is worsened by cold air and dust. Wheezing can often be felt, along with shortness of breath if the person does not get enough air. The Chest suffers a tightening feeling during asthma allergy attacks.
Symptoms for people who are allergic to certain foods can occur without regards to age. As an example, those who are allergic to crabs experience redness of the skin, excessive itching and shortness of breath. Other less severe symptoms can include aching stomachs, diarrhea and vomiting, sneezing and runny nose. A more life threatening reaction especially with children is called anaphylaxis, or the release of certain chemicals in to the body.
People who have contact dermatitis usually show symptoms as rashes on the skin. This can be caused by something unfamiliar to an allergic person, such as coming in contact with poison ivy or other pollens or in some cases metal. The rashes can be found anywhere on the body.
Allergies occurring in the gastro-intestinal part of the body can show burns in the mouth as well as in the throat. There is nausea, often accompanied by a bloated feeling. Symptoms may vary but it is usually accompanied by diarrhea. This allergic reaction can also be related to allergies caused by certain types of food.
Many of these different allergy symptoms, when encountered by allergy-sensitive people, can cause extreme harm. Where treatment is not immediately available, it can put them into an extremely stressful situation, thus making their condition even more difficult to handle. It is therefore best to be aware of potential triggers of personal allergic reaction and to avoid exposure wherever possible. In this way you can remain in control of any likely allergic reaction before any allergy symptom manifests itself.
How Allergies Work To Protect the Body – And How to Recognize Them
Recent statistics show that as much as twenty percent of the United States population – one in every five people – suffers from some kind of allergy. That’s tens of millions each year dealing with a broad spectrum of allergies, including everything from common pollen and animal fur to various kinds of foods and even some smells.
Though seldom pleasant, allergic reactions are the body’s ways of defending against attacks it perceives as harmful. Controlling allergy symptoms is largely a process of short-circuiting the body’s natural reactions to allergens in the environment.
How allergy attacks work
Allergies are a disorder of the immune system, considered a form of Type I Hypersensitivity in the body. Following the ingestion or the inhalation of an allergen, the body produces an antibody called Immunoglobulin E (or IgE) that activate certain kinds of white blood cells – the body’s most common form of immune system defense. These white blood cells, called mast cells and basophils, release the chemicals histamine and heparin as the allergen particles bind with the IgE.
Histamine is the cause of most perceived allergy symptoms, including sneezing and runny eyes. Blocking or reducing its presence in the body with anti-histamine medication is probably the most prevalent form of allergy treatment.
Three levels of allergies.
Allergies are typically classified according to three levels of severity. Mild reactions are generally limited to one area of the body. Moderate reactions are more acute, spreading to other parts of the body as the allergy attack progresses.
Severe allergic reactions occur when the body produces so much histamine and other allergy mediators in so short a time that the patient undergoes a dramatic drop in blood pressure. This condition, known as anaphylactic shock, can cause death in minutes if not treated. Researchers believe that sixteen percent of United States residents are in dangerous of anaphylactic shock, though such incidents result in less than 1,000 deaths each year.
Anaphylactic shock typically presents itself as a moderate allergy attack but then quickly develops into more painful symptoms such as difficulty breathing, abdominal pain, and dizziness. Mental confusion and lightheadedness are also possible as the brain struggles to deal with the drop in blood pressure.
Atopic reactions
Allergic responses typically happen where the body encounters them – pollen produces sneezing, and so forth. Allergies also sometimes produce an atopic reaction, meaning the appear in areas besides where the body encountered the allergen (for example, breathing pollen making someone break out in hives.) Atopic reactions are strongly hereditary and may come from an overproduction of IgE within the bloodstream.
