The answer to this question is yes. Allergies can develop at any age, even in your twenties. Allergies occur when your immune system mistakenly identifies a harmless substance, such as pollen, pet dander, or certain foods, as a threat. When this happens, your body releases chemicals, such as histamine, which cause unpleasant reactions, such as sneezing, itching, or a rash.
What Causes Allergies?
Allergies are caused by a combination of genetic and environmental factors. Your genes may make you more likely to develop allergies, but it is still unclear why some people develop allergies and others don't. Exposure to potential allergens, such as pet dander, dust mites, and pollen, can also cause allergies.
Symptoms of Allergies
Common symptoms of allergies include sneezing, nasal congestion, itchy eyes, and a rash. For some people, an allergic reaction can be more severe and result in anaphylaxis, which can be life-threatening.
Diagnosing Allergies in Your 20s
If you think you may be experiencing an allergic reaction, it is important to see your doctor. Your doctor can perform various tests to determine what is causing your reaction and recommend treatments to help alleviate your symptoms.
Treating Allergies in Your 20s
Treatment for allergies usually involves avoiding exposure to the allergen and taking medication to help relieve symptoms. If you are allergic to pollen, for example, it may be helpful to wear a mask when outdoors and to keep windows and doors closed. Your doctor may also recommend medications, such as antihistamines, decongestants, or corticosteroids, to help reduce symptoms.
