Immune System and Allergy
Allergies occur when the immune system reacts excessively to otherwise harmless substances, resulting in a range of uncomfortable symptoms. To better grasp the nature of allergies, it’s essential to understand the immune system’s role, recognise common symptoms, identify potential causes, and explore available treatment options.
The Immune System and Allergic Reactions
The immune system is responsible for defending our bodies against harmful substances. However, in individuals with allergies, the immune system mistakenly identifies harmless substances, known as allergens, as potential threats. When exposed to an allergen, the immune system triggers an inflammatory response, releasing histamines and other chemicals that cause allergy symptoms.
Common Symptoms of Allergies
Allergies can manifest in various ways, and the specific symptoms can differ from person to person. Some common allergy symptoms include:
- Respiratory Symptoms: Sneezing, coughing, wheezing, nasal congestion, runny or itchy nose, and watery or itchy eyes.
- Skin Reactions: Itchy skin, hives (raised, itchy bumps on the skin), redness, and swelling.
- Gastrointestinal Symptoms: Abdominal pain, nausea, vomiting, diarrhea, or other digestive issues.
- Anaphylaxis: In severe cases, allergies can lead to a life-threatening reaction called anaphylaxis. Symptoms may include difficulty breathing, swelling of the throat or tongue, rapid heartbeat, dizziness, and loss of consciousness.
Causes of Allergies
Allergies can be triggered by a wide range of allergens. Some common allergens include:
- Pollen: Pollen from trees, grasses, and weeds can cause seasonal allergic rhinitis (hay fever).
- Dust Mites: Microscopic insects found in house dust.
- Animal Dander: Allergies to pet hair, saliva, or skin flakes.
- Foods: Common food allergens include peanuts, tree nuts, shellfish, eggs, milk, and wheat.
- Insect Stings: Allergic reactions to bee stings, wasp stings, or bites from other insects.
Treatment of Allergies
While allergies cannot be cured completely, various treatment options can help manage symptoms and improve quality of life. The treatment approach may include:
- Avoidance: Identifying and avoiding specific allergens can help prevent or reduce allergic reactions.
- Medications: Antihistamines, nasal sprays, eye drops, and decongestants can help alleviate symptoms. In some cases, corticosteroids or epinephrine may be prescribed for severe allergic reactions.
- Immunotherapy: Allergen immunotherapy, such as allergy shots or sublingual immunotherapy, can gradually desensitise the immune system to specific allergens, reducing the severity of allergic reactions.
