what is allergies - #24245
I am really confused about what is allergies, and I feel like I’ve been dealing with this for a while now. It started last summer when I noticed I was sneezing a lot, like, every time I stepped outside. My eyes would get super itchy too. I thought I was just catching a cold or something, but it never really went away. Fast forward to spring this year, and it's like the symptoms are back with a vengeance! My doctor said I might have seasonal allergies, but honestly, I’m just trying to understand what is allergies and why it’s affecting me this way. I did some tests, and they said I might be allergic to pollen, but why would I just suddenly get this? I mean, I never had this before, right?! Also, I heard a friend mention food allergies can be a thing too, and now I'm wondering like how are these connected? Like, what is allergies really? Is there anything I can do to lessen these insane symptoms? It's driving me bonkers, and I can't even enjoy a day outside without feeling like I'm going to sneeze my head off! Any advice or insights from you guys would be super helpful, thanks!

Doctors' responses
Allergies are basically an exaggerated response by your immune system to certain substances that it sees as a threat, even though they’re harmless to most people. When you come in contact with an allergen, like pollen in your case, your body releases chemicals such as histamine, which leads to symptoms like sneezing, eye itching, and a runny nose. It’s not unusual for people to develop allergies later in life, even if they haven’t had them before. These can be influenced by genetic predisposition and environmental exposures over time. Seasonal allergies are common, especially with pollen during spring and early fall, and your symptoms aligning with spring would support that diagnosis. Food allergies involve the same immune response but to different allergens found in foods, and they don’t necessarily correlate with seasonal allergies—you can have one without the other. To manage your symptoms, over-the-counter antihistamines can be effective, but make sure they’re non-drowsy if you’re taking them during the day. Nasal corticosteroid sprays can also be helpful to reduce inflammation. It’s wise to keep your windows closed and use air conditioning during high pollen seasons, and regularly clean your home to minimize exposure. Showering after being outside can be particularly beneficial since it removes pollen from your skin and hair. A more specific approach might include seeing an allergist for further testing or considering allergy shots (immunotherapy) if your symptoms are severe. If you ever develop difficulty breathing, swelling in the throat, or experience a severe headache during an allergic reaction, it’s vital to get medical attention immediately, as these can be signs of a more serious reaction.
