Yes, controlling allergies can play a crucial role in managing asthma symptoms. Strategies for controlling allergies may include avoiding exposure to known allergens, using allergen-proof bedding and air filters, regularly cleaning indoor environments to reduce dust and mold, and taking allergy medications such as antihistamines or nasal corticosteroids. For individuals with allergic asthma, allergen immunotherapy (allergy shots) may also be recommended to desensitize the immune system to specific allergens and reduce asthma symptoms.
