Signs and Causes of Allergic Cough

A cough is a natural reflex that helps clear your airway when foreign particles, mucus, or irritants enter your respiratory tract. Occasional coughing is normal, but persistent coughs lasting over three weeks may indicate underlying health issues, such as allergies, infections, or other conditions.

An allergy-induced cough differs from a cold and results from an allergic reaction. It often presents with symptoms similar to cold symptoms, including nasal congestion, runny nose, and sore throat, yet it lacks body aches and fever.

Allergic cough involves three main phases: inhaling, increased pressure in the throat, and a forceful exhale with open vocal cords. Allergic cough occurs due to hypersensitivity triggered by specific allergens. Identifying these triggers is crucial before initiating treatment. Common allergy symptoms include nasal runoff, itchy eyes, and sore throat, but they do not involve fever or body aches. Sinus and ear infections may also develop as one-off effects of allergies, potentially leading to sinusitis due to nasal swelling.

Many individuals experience improvement over time, especially as they age, since immune system responses may weaken. However, allergies to foods, latex, or insect stings often persist. Treatment options vary based on allergy causes, including allergen avoidance, medications like antihistamines and decongestants, nasal steroids, and immunotherapy to build immunity. Prevention emphasizes maintaining cleanliness, avoiding dust and scented products, and minimizing exposure to pollutants. Seeking medical help early ensures proper management and reduces the risk of progression to conditions like asthma.
