In the spring, as flowers bloom, pollen begins to drift. Pollen allergies are becoming more common, which usually indicates an immune dysfunction in the allergic person.

The body's immune system incorrectly recognizes the initially harmless pollen as a 'harmful substance' and produces a series of abnormal immune responses to remove the 'harmful substance'.

The main symptoms of pollen allergy are an itchy nose, nasal congestion, sneezing, and a watery, runny nose; some patients may be accompanied by itchy eyes, itchy ears, itchy palate, itchy pharynx, itchy skin, hives, etc., and severe cases, coughing, tightness in the chest, shortness of breath and difficulty in breathing.

Pollen allergies are distinctly seasonal and temporal and can last for months. The severity of symptoms is closely related to the type and amount of pollen exposure.

Pollen allergy sufferers must go to the hospital for formal diagnosis and treatment.

First, you must go to the relevant department to check for allergens. After clarifying the allergens, the doctor will provide different diagnoses and treatment programs for specific conditions.

During the peak period of pollen, the symptoms are usually more apparent, and the symptomatic treatment is mainly based on drugs supplemented by immunomodulatory treatment.

After clarifying the patient's allergen, the doctor can use a subcutaneous injection or sublingual method to gradually increase the allergen extract in small amounts to improve the patient's tolerance to that allergen. So that when the patient is exposed to the allergen again, the symptoms are reduced or no longer develop.

The best specific immunotherapy period for spring pollen allergy is from June to February; the best specific immunotherapy period for fall pollen allergy is from October to July.

To prevent pollen allergy, you should not only go to the hospital to determine which pollen is causing your allergy but also to clarify whether you are allergic to single pollen or multiple pollen, and the period of prevention and treatment is different for different pollen.

Depending on the type and number of pollen allergies, the doctor will suggest reasonable preventive measures and treatments and decide on the timing of the medication.

Preventive medication 1-2 weeks before the peak pollen season can reduce the severe symptoms of the peak pollen season. For example, topical nasal sprays can be used in advance, and eye drops can be used for those with eye symptoms.

Pollen allergy sufferers should avoid going out to parks, fields, and other areas with high levels of allergenic pollen during the peak pollen season. If you must go out, it is recommended that you wear a protective mask.

In addition, developing good habits, a healthy diet, regular work and rest, early to bed and early rise, and not staying up late can also reduce pollen allergy symptoms to a certain extent.
