What are Allergic Shiners?
Allergy is defined as “an immune response to something that isn’t normally harmful.” The term allergic comes from the Greek word allos , meaning “all” or “every,” and kinema , which means skin. An allergy occurs when your body produces antibodies against certain substances found on the outside of your body (such as pollen) but not inside it (like dust mites). These allergens cause your body to produce chemicals called histamines, which can damage the lining of your airways and lungs. If you have asthma, allergies may cause wheezing, shortness of breath, coughing up blood or even death.
The most common types of allergies include:
Dust Mite Allergies Dust mites are tiny insects that live on dirt and other organic matter such as dead leaves and grasses. They are very small, ranging in size from the size of a grain of rice to that of a poppy seed. Most people do not notice them because they only live on these types of materials.
However, if you have allergies to dust mites, then you will experience itching and sneezing whenever you come into contact with these tiny creatures. You may also develop hives or swelling around your mouth and eyes when exposed to dust mites.
Food Allergies Food allergies are reactions to different types of foods that occur when the body mistakenly identifies certain food substances as harmful invaders. The immune system releases antibodies against the foods, which causes the release of chemicals that can lead to swelling and other allergic reactions. These reactions can be mild or life-threatening.
Common food allergens include milk, eggs, peanuts, tree nuts, wheat, soy, fish and shellfish.
Mold Allergies Molds are types of fungus that thrive on moisture. They can be black, white, blue or green in color and may be seen growing on food, damp carpets or walls, or even outdoors. When you have mold allergies, your body will produce antibodies against the mold allergens which can cause sneezing, itchy, watery eyes, runny noses and wheezing.
Mold allergies are becoming more common due to increased moisture in buildings caused by air conditioning or humidity.
Pollen Allergies Pollen is the fine powder produced by flowers, trees, grasses and other plants. Each type of plant produces a different kind of pollen. For example, trees produce pollen in the springtime.
Most people who have tree pollen allergies tend to have symptoms such as runny noses, watery, itchy eyes and sneezing during certain times of the year when the tree is releasing large amounts of pollen.
Medications There are a wide range of pharmaceutical drugs that can cause allergic reactions. Common types of drugs that can cause reactions include antibiotics, anti-fungal drugs, anti-inflammatories, antimalarial drugs and antiviral drugs.
