Seasonal Allergy

Seasonal allergy, also known as hay fever or allergic rhinitis, is a common medical condition that occurs when the body's immune system overreacts to particles in the air that are typically harmless to most people.

Causes and Triggers

The primary causes of seasonal allergies are the release of pollen from trees, grasses, and weeds during different times of the year. The specific allergens that trigger symptoms vary by region and season:

• Trees: Pollen from trees such as oak, maple, and birch is typically released in early spring.
• Grasses: Grass pollen is usually released in late spring and early summer.
• Weeds: Weed pollen, including ragweed, is commonly released in late summer and early fall.

Symptoms

The symptoms of seasonal allergies can vary in severity but often include:

• Runny or stuffy nose
• Sneezing
• Coughing
• Itchy, watery eyes
• Postnasal drip (a sensation of mucus running down the back of the throat)
• Headaches and fatigue

Diagnosis

Diagnosing seasonal allergies typically involves a combination of medical history, physical examination, and diagnostic tests:

• Allergy testing: Skin prick tests or blood tests can help identify specific allergens.
• Medical history: A detailed history of symptoms and when they occur can provide clues about the type of allergy.

Treatment and Management

Treatment for seasonal allergies focuses on relieving symptoms and may include:

• Medications: Antihistamines, decongestants, and corticosteroids can help alleviate symptoms.
• Immunotherapy (allergy shots): Regular injections of small amounts of the allergen can help desensitize the body over time.
• Avoidance: Staying indoors when pollen counts are high, using air conditioning to filter the air, and avoiding outdoor activities during peak pollen times can help reduce exposure.

Prevention

While it's not possible to completely prevent seasonal allergies, there are steps that can be taken to minimize symptoms:

• Monitor pollen counts: Checking local pollen forecasts can help plan outdoor activities accordingly.
• Use HEPA filters: High-efficiency particulate air (HEPA) filters in homes and vehicles can reduce exposure to allergens.
