What Causes Late-Onset Allergies?
Allergies can develop at any time, but many people find that they experience their first allergic reactions as adults. Late-onset allergies can be caused by a variety of factors, including changes in the environment, exposure to new allergens, and genetic predisposition.
Environmental Factors: Allergens such as pollen, dust, and pet dander can cause allergic reactions, even when present in small amounts. People who move to a new city or area may be exposed to allergens that they had not encountered in their previous location. This may cause an allergic reaction, even if they had never experienced allergies before.
Exposure to New Allergens: Many people are exposed to new allergens as adults, either through travel or through contact with new people or animals. Even if a person has not been exposed to an allergen before, they may develop an allergic reaction if they are exposed to it for the first time.
Genetic Predisposition: Some people are simply more likely to develop allergies due to their genetics. Even if a person has not been exposed to a certain allergen, they may still develop an allergic reaction if their body is predisposed to it.
What Are the Symptoms of Late-Onset Allergies?
The symptoms of late-onset allergies are similar to those of any other type of allergic reaction. These may include sneezing, itching, runny nose, watery eyes, and hives. In some cases, more severe symptoms such as difficulty breathing, wheezing, and abdominal pain may occur.
Treatment for Late-Onset Allergies
The best way to treat late-onset allergies is to avoid the allergen that causes the reaction. If this is not possible, then over-the-counter or prescription medications may be used to reduce symptoms. Antihistamines, decongestants, and corticosteroids can all be used to treat allergies. In more severe cases, allergy shots may be recommended.
