What Are the Symptoms of Pollen Allergy?

Pollen allergy inherently exhibits seasonal patterns—typically occurring from March to May, when many plants bloom, and again from June to September. It primarily manifests as catarrhal inflammation of the respiratory tract and conjunctiva, often accompanied by skin lesions and involvement of other organ systems. Pollen allergy is a common condition in allergy clinics, with incidence rates rising annually, posing significant threats to human health. So, what are the symptoms of pollen allergy? Below, we address this question.

What Are the Symptoms of Pollen Allergy?

1. Allergic Rhinitis

Pollen allergy frequently presents as allergic rhinitis, characterized by sneezing, rhinorrhea (runny nose), lacrimation (tearing), and intense itching of the nose, eyes, and external auditory canals. In severe cases, it may trigger tracheitis, bronchial asthma, or cor pulmonale. Pollen induces allergic reactions due to its rich protein content; certain proteins act as primary allergens responsible for sensitization. It is recommended to consume light, vitamin-rich foods regularly.

2. Allergic Asthma

Pollen allergy commonly manifests as allergic asthma, whose hallmark symptoms include paroxysmal coughing, dyspnea (shortness of breath), acute asthmatic attacks, and production of white, frothy, mucoid sputum during coughing. Individuals of all age groups may develop pollen-induced allergic asthma. To mitigate risk, maintain good hygiene: wash hands frequently, change clothes and bed linens regularly, dry laundry indoors whenever possible, and ensure adequate indoor ventilation. When outdoors, avoid prolonged sun exposure and consider wearing a scarf or protective goggles to minimize direct contact between pollen and the eyes or respiratory tract.

3. Allergic Conjunctivitis

Pollen allergy often presents as allergic conjunctivitis, whose typical symptoms include tearing, ocular pruritus (itching), eyelid swelling, and photophobia. Additionally, patients may experience purulent mucoid discharge and conjunctival hyperemia (congestion). Furthermore, pollen allergy may also manifest as allergic urticaria—characterized by variable-sized, bright or pale red wheals on the skin—and may be associated with decreased appetite, abdominal pain, diarrhea, and fever.

The above outlines the major symptoms associated with pollen allergy. We hope this information proves helpful to you.
