Common allergies are known discomforts or reactions that occur when the immune system comes into contact with a harmless substance, also known as an allergen. Normally a person who is not allergic to a substance will not feel any reaction.
However, the opposite happens if the person is allergic to a substance. That’s because the immune system is activated mistakenly believing that this substance is harmful to your body. To protect the body, the immune system produces antibodies that cause certain cells to release chemicals into the bloodstream. The chemical acts on the eyes, nose, throat, lungs, skin, or gastrointestinal tract and causes reactions; sneezing, runny nose, nasal congestion, itching, rash, nausea, vomiting, stomach ache, diarrhea and many others.
It is still unknown how common allergies develop in a person. Some allergies are hereditary, all family members can have the same allergy to a certain type of food.
Common allergies are often caused by a direct intake of food substances. Any form of food is a potential allergen for sensitive individuals. The most common are allergies to cow’s milk, eggs, chicken, shellfish and the like.
Another source of common allergies is airborne substances such as pollen, dust, smoke, perfumes, and other chemicals. These substances can affect the respiratory tract, causing sneezing, coughing, and shortness of breath.
A person can also develop an allergic reaction to inhaled fungal spores or particles. The mold spores trigger a reaction in the cellular tissues lining the nasal passages. Because the substance is so small, it can easily reach the lungs and cause the buildup of mucus, wheezing, and shortness of breath associated with asthma. Dust and animal hair (from cats and dogs) can also cause common allergies that trigger asthma attacks.
There are also artificial allergens that cause all kinds of reactions. “Meat casing asthma” is a common form of allergy resulting from inhaled polyvinyl chloride vapors. This substance is found in packages used to wrap processed foods. When inhaled, it can cause burning eyes, sore throat, wheezing and shortness of breath, upset stomach, and other discomfort.
Another common allergy is a reaction to the smog produced by motor vehicles. Smog is made up of hydrocarbons, nitrogen oxides, and other chemicals activated by energy from sunlight. Smog can impair the normal functioning of the lungs, causing respiratory discomfort.
Medicines and drugs, such as penicillin or serums used in inoculations, can also cause allergic reactions. According to medical scientists, the chemicals in certain medications combine with protein molecules in the patient’s body and can form an allergen, which can trigger a reaction in the body’s immune system.
Another source of common allergies is insect bites by bees, fire ants, wasps, wasps, or hornets. All of this can cause severe allergic reactions. A single sting for a sensitive person can cause a serious drop in blood pressure, shock, and possibly death.
Antihistamine is the best cure for common allergies, an effective antihistamine is the best cure. This neutralizes the allergen and relieves most symptoms.
