Overview
Allergies are a type of immune system disorder in which the body reacts to a foreign substance, such as dust, pollen, or pet dander, as if it were a harmful invader. Allergies can range from mild to severe, and can become more severe over time. Many people find that their allergies become more severe each time they are exposed to the allergen, which can cause a range of uncomfortable and even dangerous symptoms.
Causes of Increasing Severity
There are several possible causes for why allergies become more severe each time a person is exposed to an allergen. One of the most common is called “allergic sensitization.” This occurs when a person is exposed to an allergen multiple times, and their body begins to recognize it as a foreign invader. As a result, their immune system responds more strongly each time they are exposed.
Another possible cause of increasing allergy severity is “allergic cross-reactivity.” This occurs when a person is allergic to one allergen, such as a pollen, but is then exposed to another allergen, such as a pet dander, which their body incorrectly identifies as the same allergen. As a result, their body responds with a stronger allergic reaction than it would have if they were just exposed to the first allergen.
Treatment and Prevention
The best way to prevent allergies from becoming more severe is to avoid exposure to allergens as much as possible. This can involve taking steps such as using air purifiers, keeping windows closed during high-pollen times, and using special covers on mattresses and pillows to reduce dust mite exposure.
If a person is already experiencing severe allergy symptoms, then they may need to take medication to manage their allergies. Antihistamines, corticosteroids, and other medications can be used to reduce the severity of allergic reactions. It is important to speak to a doctor before taking any medication, as some medications may have side effects.
Finally, allergy immunotherapy may be an option for people whose allergies are particularly severe. This involves exposing the person to small amounts of the allergen over a period of time, which can help the body to build up a tolerance and reduce the severity of allergic reactions.
Conclusion
Allergies can become more severe each time a person is exposed to an allergen, which can lead to uncomfortable and even dangerous symptoms. There are several possible causes for this, such as allergic sensitization and allergic cross-reactivity. The best way to prevent allergies from becoming more severe is to avoid exposure to allergens as much as possible, and if necessary, take medication to manage the symptoms. Allergy immunotherapy may also be an option for people whose allergies are particularly severe.
