Question 1

What are allergies and how do they develop?

Accepted Answer

Allergies are immune system reactions to normally harmless substances (allergens) such as pollen, dust mites, mold, pet dander, or certain foods. They develop when the immune system becomes sensitized-producing IgE antibodies upon first exposure. On re?exposure, allergens cross?link IgE on mast cells and basophils, triggering release of histamine and other mediators that cause symptoms?NCBI InformedHealth: Allergies, 2023.

Question 2

Are allergies genetic or hereditary?

Yes, allergies often run in families. If one or both parents have allergies, their children are more likely to develop them. However, the specific type of allergy may vary among family members.

Question 3

Are allergies contagious?

Can allergies cause flu-like symptoms or fatigue?

When do allergies tend to get worse and why?

Accepted Answer

Allergies may worsen in the morning, at night, or after it rains due to pollen release, indoor exposure, or mold growth. Symptoms may also intensify during pregnancy, springtime, or in high-pollen regions.

Question 8

How do allergies affect the body, including eyes, ears, and skin?

Accepted Answer

Allergies can cause itchy or watery eyes, ear pressure or popping, and skin reactions like hives or eczema. These symptoms occur as the body’s immune system responds to allergens in different areas.
