What are the different types of allergies?
Allergies are conditions where a hypersensitive immune system reacts to otherwise harmless substances in one’s environment. Its symptoms may include shortness of breath, sneezing, red eyes, itchy rashes, runny nose and swelling. A few common types of allergies are explained below: • Food Allergies: It is a condition where the immune system reacts soon after the intake of certain foods. The allergen food can trigger symptoms, such as swollen airways, hives and digestive issue. In some cases, food allergy can trigger a serious, life-threatening reaction called anaphylaxis. • Eye Allergies: It is a condition characterized by itchy, red and swollen eyes due to an overreaction from the immune system. The allergens can be dust mites, feathers, pollen, pet dander, mold and other indoor and outdoor objects. Eye allergies are collectively also called allergic conjunctivitis. The chemical chistamine is released by the body that causes inflammation and swelling of the blood vessels in the eyes. • Dust Allergies: It is an allergic reaction to the small bugs commonly found in household dust. Dust mite allergy shares some of its symptoms with hay fever, such as runny nose and sneezing. Some patients of dust mite allergy may also experience asthmatic signs like difficulty in breathing and wheezing. • Seasonal Allergies: Seasonal allergic rhinitis, also called hay fever is a condition where the allergic symptoms occur during specific times of the year. Usually, it is contracted when outdoor molds release spores or grasses or when trees and weeds release small pollen particles into the air to fertilize other plants. • Plant Allergies: Allergic rhinitis or plant allergy is an allergic reaction to certain plants and their pollen. Its symptoms include irritated, itchy and watery eyes, runny nose, sneezing, congestion and fatigue. The condition may occur only during certain seasons or times of the year, such as during the spring bloom. Alternatively, patients may suffer from permanent allergic rhinitis which is a chronic allergic condition that stays throughout the year and causes nasal congestion and runny nose. It may be triggered by dust mites or other allergens existing around you the whole year. The common triggers for plant allergies – temporary or permanent – are trees, grasses, ragweed, etc.
