What Are the Symptoms of an Allergy?
An allergy occurs when the body’s immune system sees a substance as harmful and overreacts to it. The symptoms that result are an allergic reaction.
The substances that cause allergic reactions are allergens. Allergens can get into your body numerous ways to cause an allergic reaction.
- You can inhale allergens into your nose and your lungs. Many are little enough to float through the air. Examples are pollen, home dust, mold spores, cat and dog dander and latex dust.
- Your body can own allergens injected into it. This includes medicine given by needle and venom from insect stings and bites.
- You can ingest allergens by mouth. This includes food and medicines you eat or swallow.
- Your skin can absorb allergens. Plants such as poison ivy, sumac and oak can cause reactions when touched. Latex, metals, and ingredients in beauty care and household products are other examples.
What Are Eye Allergies?
Eye allergies are common. Eye allergies are a reaction to indoor and outdoor allergens that get into your eyes.The tissue that lines the inside of the eyelid and exterior of the eyeball becomes inflamed and swollen and leads to itching, redness, tearing and irritation of the eyes.
What Is Rhinitis (Nasal Allergies)?
The expression rhinitis means “inflammation of the nose.” When the nose becomes irritated by allergens or irritants, it may produce more and thicker mucus than usual.
This drainage can irritate the back of the throat and cause coughing. Allergic reactions can also cause congestion, itchy nose or throat, sneezing, a runny nose and itchy, watery eyes.
What Is Sinusitis?
Sinusitis is an infection or inflammation of the sinuses.
A sinus is a hollow space. There are numerous sinuses in the body, including four pairs inside the skull.
They serve to lighten the skull and give resonance to the voice. These sinuses are lined with the same helpful of tissue that lines the inside of the nose. The same things that can cause swelling in the nose – such as allergies or infection – can also affect the sinuses. When the tissue inside the sinuses becomes inflamed, mucus discharge is increased. Over time, air trapped inside the swollen sinuses can create painful pressure inside the head. This is a sinus headache.
