Seasonal Allergies: Causes, Symptoms, and Relief Tips

Allergies arise when the immune system responds abnormally to otherwise harmless allergens. These can include some foods, medications, pollen, pet dander, and bee venom. When exposed to an allergen, an allergic person’s immune system incorrectly treats it as harmful and generates Immunoglobulin E (IgE) antibodies.

Histamine is released when IgE binds to mast cells in the gastrointestinal tract, skin, and airways. This substance causes inflammation and allergic symptoms that can range from modest discomfort to severe, perhaps lethal, anaphylaxis.

While there is no cure for allergies, treatments such as immunotherapy, antihistamines, decongestants, nasal steroids, and asthma medications can help manage symptoms and improve quality of life.

Common Allergy Symptoms

Allergy symptoms differ based on the specific allergen and how the individual’s immune system reacts. Some of the most common symptoms include:

1. Respiratory Symptoms include sneezing, runny or stuffy nose, coughing, wheezing, shortness of breath, and itchy, watery eyes.
2. Skin Reactions can include rashes or hives, redness, itching, swelling
3. Digestive Issues like nausea, vomiting, diarrhoea, and stomach cramps are common with food allergies.
4. Severe allergic reactions, like anaphylaxis, can cause breathing difficulties, throat and tongue swelling, low blood pressure, and unconsciousness.

If you experience anaphylaxis symptoms, seek emergency medical care immediately, as it can be life-threatening.

Causes

Allergic reactions are triggered by allergens, substances that provoke an immune system response. Common allergens include:

1. Airborne allergens consist of pollen (from trees, grass, and weeds), mold spores, dust mites, and pet dander.
2. Food allergens include peanuts, tree nuts, dairy products, shellfish, eggs, and wheat.
3. Insect stings from bees, wasps, and fire ants.
4. Certain medications like NSAIDs
5. Contact allergens such as latex, certain metals (nickel), and chemicals in cosmetics and detergents

Diagnosis

If you suspect you have allergies, consult an allergist, a specialist in diagnosing and treating allergies. A proper diagnosis involves:

Skin Prick Test:

A healthcare provider pricks your skin with small amounts of various allergens to observe any reaction.

Blood Test (IgE Test):

This test detects allergy-related antibodies in your bloodstream. While not as sensitive as skin tests, it helps identify allergic reactions.

Treatment

 This section explores various methods to manage and alleviate allergy symptoms, including avoidance strategies, medications, and long-term therapies.

Avoiding Allergens

The most reliable method to prevent allergy symptoms is to steer clear of known triggers. This includes staying indoors during high pollen seasons, using hypoallergenic bedding, and avoiding specific foods if you have food allergies.

Medications

Several medications can help manage allergy symptoms, including:

• Antihistamines block histamine, reducing sneezing, itching, and a runny nose.
• Nasal Sprays
• Decongestants provide temporary relief from nasal congestion but are not recommended for prolonged use due to possible side effects.
• Immunotherapy (Allergy Shots or Drops)

Immunotherapy offers long-term relief by gradually desensitizing the body to allergens through controlled exposure. This is especially helpful for severe seasonal allergies and insect venom allergies.

Managing Food Allergies

Individuals with food allergies should meticulously read food labels and prevent cross-contamination. In the U.S., food packaging must list common allergens. However, hidden allergens in processed foods or nonfood items (e.g., cosmetics) can still pose a risk.

Prevention Strategies

While allergies cannot always be prevented, taking proactive steps can reduce symptoms and reactions.

For Environmental Allergies

• Use high-efficiency particulate (HEPA) air filters.
• Keep pets out of the bedroom if you are allergic to animal dander.
• Wash bedding frequently in hot water.
• Vacuum and dust regularly to remove allergens.

For Insect Allergies

• Wear protective clothing when outdoors.
• Avoid wearing floral perfumes that attract insects.
• Keep insect repellent handy.

Complications

Having allergies increases the risk of developing other conditions, such as:

• Anaphylaxis: Severe allergic reactions that require immediate medical attention.
• Asthma: Many people with allergies also suffer from asthma, which leads to breathing difficulties.
• Sinus and Ear Infections: Chronic allergies can increase the risk of infections.

Conclusion

Although allergies are common, they can be managed with the right approaches. Recognising triggers, receiving the appropriate diagnosis, and following a treatment plan can help you live a pleasant, symptom-free life. If you think you have allergies, consult a healthcare professional for customized advice and treatment options. Being aware of allergies and taking preventative measures can significantly reduce the discomfort and risks connected with them.
