Either way, allergies are on the rise. Read more

I have an allergy to nuts and I was wondering if my children would also be allergic?

I have an allergy to nuts and I was wondering if my children would also be allergic?

Nut allergy: Maybe. Your children may have inherited genes from you that make them more likely to develop an allergy, but they do not inherit a specific allergy to a food e.g. Nuts. The children have to be exposed to food proteins in the diet, before an allergy can develop. Once one develops an allergy then they are always allergic and need proper medical attention to prevent severe problems. Read more

Can a parents allergies be passed on to their children?

Can a parents allergies be passed on to their children?

Not exactly: The ability to react to certain proteins in an allergic way is passed on from parents to their children, but a specific allergy is not. So if a mom is allergic to pollen and the dad is allergic to fire ants, their child may develop allergies but it may be to a food instead. If 1 parent has allergies, the child is 50% likely to develop allergies, but it's a 75% chance if both parents are allergic. Read more

Can a parents' allergies to various foods be passed on to their children?

No: The condition of being allergic is certainly an inherited property. Often, that tendancy is greater in children whose biological mother has allergies.

Is Zantac (ranitidine) (histamine blocker) used for children for allergies.?

Add-on for hives: Ranitidine (zantac), although it's a different kind of histamine blocker (h2 for acid vs h1 for allergies), has been shown to have some anti-allergy properties, especially when used with an h1 blocker like Benadryl (diphenhydramine) for hives. There was actually one study that showed benefit in nasal allergies, but I don't know anyone that prescribes it for that purpose. Read more
