Question 1

are allergic reactions hereditary?

Accepted Answer

Yes and No: Allergies to specific triggers, like peanuts, shrimp, dust mites, etc., are not inherited from one generation to the next. However, the general state of "being allergic" (atopy) can be hereditary, so children of parents with asthma or seasonal allergies may have increased risk to develop those or other allergic conditions. See an allergist for more information.

Question 2

are allergic reactions always immediate?

Accepted Answer

Depends: An allergic reaction usually occurs within 20 mins after exposure to an inhaled allergen but it may occur as late as 2 hrs with food allergy and 6-8 hrs with red meat allergy. For allergic skin reactions, it is usually from a different immune mechanism when the contact is on the skin. The reaction may not develop until 1-3 days after the exposure (poison ivy is one such example).

Question 3

what are symptoms of allergic reactions?

Accepted Answer

A range of symptoms: Allergic reactions can be non life threatening and only include hives and itching, or can include multiple organ systems and present with swelling, throat tightening, cough, wheeze, nausea, vomiting, diarrhea, and light-headedness. See an allergist for definitive allergy testing.

Question 8

are hypersensitivity and allergic reactions synonymous or different?

Accepted Answer

Question 9

i am getting normal reactions or allergic reactions to insect bites?

Accepted Answer

Probably normal: Allergic reactions to insects most commonly occur with stinging insects like bees, wasps and fire ants.  Local reactions to other insects are generally not allergic.  Allergic reactions usually cause symptoms away from the bite.  So, bitten on the toe and toe swells= not allergic.  Bitten on the toe and lip swells= allergic.

Question 10

is it possible to develop allergic reactions from having any type of worm?

Accepted Answer

Strongyloides: This is a roundworm called threadworm. Symptoms include dermatitis: swelling, itching, and mild hemorrhage at the site where the skin has been penetrated. If the parasite reaches the lungs, the chest may feel as if it is burning, and wheeze and cough may result, along with pneumonia-like symptoms (löffler's syndrome). If a person has traveled to tropics/subtropic especially rural areas get seen.
