How Hay Fever Develops
When a person with hay fever is exposed to an allergen, their immune system identifies it as a threat. The body then produces antibodies called immunoglobulin E (IgE). These antibodies trigger the release of histamines and other chemicals from mast cells, leading to the symptoms associated with hay fever.
What is an Allergen?
An allergen is a typically harmless substance that triggers an allergic reaction in vulnerable people. Allergens can be found in various forms, including in the air, food, medications, and materials that come into contact with the skin. When a person with allergies is exposed to an allergen, their immune system mistakenly identifies it as a threat and reacts by producing antibodies called immunoglobulin E (IgE).
Examples of these substances are:
- Pollen from trees, grasses, and weeds is more prevalent in certain seasons (spring, summer, fall).
- Dust mites are found in household dust.
- Pet dander, e.g., skin flakes, saliva, and urine from pets.
- Mold Spores: Both indoor and outdoor molds can release spores that are inhaled.
- Airborne irritants such as smoke, strong odors, and pollution.
Diagnosis of Hay Fever
Hay fever is usually diagnosed based on a person’s medical history and symptoms. To identify specific allergens, doctors may recommend:
- Skin Prick Test where small amounts of allergens are applied to the skin with a tiny puncture to see if a reaction occurs.
- Blood Test to measures the level of IgE antibodies to specific allergens in the blood.
Symptoms of Hay Fever
Many things can indicate or announce the presence of hay fever. This makes the symptoms numerous, can range from mild to severe and typically:
- Frequent and uncontrollable sneezing, often in bouts.
- Clear, watery discharge or nasal congestion.
- Persistent itching sensation.
- Inflammation and tearing of the eyes.
- Mucus running down the back of the throat.
- General feeling of tiredness due to disrupted sleep or persistent symptoms.
Complications of Hay Fever
Hay fever, while often considered a minor condition, can lead to several complications if not properly managed. These complications can impact a person’s quality of life and may lead to more serious health issues. Although there are many such conditions, below are five potential complications of hay fever:
Sinusitis: The inflammation or swelling of the tissue lining the sinuses. When hay fever causes prolonged nasal congestion, it can block the sinuses and create an environment where bacteria and viruses can thrive. Symptoms include facial pain or pressure, thick nasal mucus, reduced sense of smell, cough, and congestion.
Asthma: Hay fever and asthma often occur together. If you have both conditions, hay fever can worsen asthma symptoms and make them more difficult to control. The symptoms are, but are not limited to, shortness of breath, chest tightness or pain, wheezing, and coughing. Hay fever can trigger or worsen these symptoms, especially during allergy seasons.
Ear Infections: Allergic reactions can cause inflammation and congestion in the Eustachian tubes, which connect the middle ear to the throat. This can lead to fluid buildup and infections.
The build up to this might include ear pain, fluid drainage from the ear, hearing loss, and a feeling of fullness in the ear.
Sleep Problems: The symptoms of hay fever, such as nasal congestion, itching, and sneezing, can significantly disrupt sleep. This can lead to daytime fatigue, difficulty concentrating, and overall reduced productivity. Chronic sleep deprivation can affect mood, increase the risk of accidents, and reduce overall well-being.
Decreased Quality of Life: Persistent hay fever symptoms can interfere with daily activities, work, and social interactions. The constant discomfort and need to manage symptoms can lead to stress, anxiety, and even depression. These may make individuals with severe hay fever avoid outdoor activities or certain environments, limiting their lifestyle and opportunities.
Effective Ways to Manage Hay Fever
As mentioned earlier, hay fever is an allergic reaction to airborne substances such as pollen, dust, or pet dander, and managing it effectively involves a combination of avoiding allergens, using medications, and adopting lifestyle changes.
Avoid Allergens: Pollen counts are usually highest in the early morning and late afternoon. Staying indoors during these times can help reduce exposure. Also, keeping windows and doors closed and using air conditioning with a clean filter to keep pollen from entering the home can be an effective way to stay safe. Encase mattresses and pillows in allergen-proof covers to reduce exposure to dust mites and pet dander. After spending time outdoors, shower and change clothes to remove pollen from your body and clothing.
Use Medications: Over-the-counter antihistamines such as cetirizine, loratadine, and fexofenadine can help reduce symptoms like sneezing, itching, and runny nose. Nasal corticosteroids, such as fluticasone and mometasone, reduce inflammation in the nasal passages and are very effective for treating nasal symptoms. Also, oral or nasal decongestants such as pseudoephedrine or oxymetazoline can relieve nasal congestion but should be used with caution and not for extended periods. For severe hay fever, allergy shots can help desensitize the immune system to specific allergens over time, and medications like montelukast can help with allergic symptoms, especially if asthma is also present.
Adopt Lifestyle Changes: This starts with a good and balanced diet and hydration: A healthy diet and adequate hydration can support your immune system. Some people find that reducing dairy intake helps with mucus production. Saline Nasal Irrigation, Use of HEPA Filters, and Wearing Sunglasses and Hats have been found to be effective.
Seek Professional Advice: If over-the-counter medications are not effective, consult an allergist who can offer a personalised treatment plan and prescribe stronger medications or treatments like immunotherapy. Keep track of your symptoms and any triggers you notice. This can help your healthcare provider adjust your treatment plan as needed.
