Dr. Francisco Pernas, Otolaryngologist with Baptist Health South Florida, says allergies tend to run in families, because the immune system is something you inherit genetically. "If your parents had asthma, allergies, you're likely to maybe develop those as well." The most common allergens are pollen, mold, household dust, animal dander, food, medicine, feathers, and bug stings.
Dr. Francisco Pernas, Otolaryngologist with Baptist Health South Florida, says there are many ways of doing skin testing: they can do a scratch test, in which they scratch you with the antigen that they are testing, and they also can do the subcutaneous injection, using a small needle to inject some of that antigen underneath your skin. He says there is also the multi-test. "They have this extent that they roll over your skin, and then they can tell based on what you react to."
Dr. Francisco Pernas, Otolaryngologist with Baptist Health South Florida, says doctors have recommended not giving your kids peanuts for the first three years of life. "Then we rescinded that, because we found out that if you waited until three years of age and then you presented them with peanuts, they might have even higher reactions." "You have all these vaccines that you get as a child and you are so protected that your body picks a fight with the peanuts, or whatever food that you're eating that really you should not be reacting to."
Dr. Francisco Pernas, Otolaryngologist with Baptist Health South Florida, explains the difference between an allergy and a cold. "There is a time difference. An allergy tends to be prolonged, it tends to last a lot more time. A cold tends to last a couple of weeks, you can get over it with some hydration." Regarding diagnosis, he says doctors can often tell right away that someone has allergies. "You do not need a test right away to diagnose allergies. Some people want to know what they have allergies to, and we can do blood test or skin test."
Dr. Francisco Pernas, Otolaryngologist with Baptist Health South Florida, explains you are not necessarily born with allergies, you can develop them as young child. "In the first year of life, kids typically do not have allergies. It's this immune system component that we haven't really identified yet, why some people are so pretty supposed to react into things that they should not be reacting to." He also says there are some people that treat allergies for a number of months, or a number of years, with medications, and the body can stop reacting to the antigen.
