Does constant allergies like sneezing, asthma etc. mean a weak immune system?
No, if it is a true allergy and not a cold/infection… your immune system is just confused. This is over simplified but basically what happens when a bacteria/virus enters your body the immune system recognizes it by markers or flags on the intruder. However in a true allergy the body incorrectly identifies normal inoccuous (not harmful) substances like pet dander/pollen/dust and tries to attack it as if it was a dangerous invader.
