Allergy symptoms: what you need to know about treating and preventing allergies.

Allergies are the result of an immune system response to a substance that is normally harmless, such as pollen, dust mites, specific foods, pet dander, insect stings, and other environmental factors. Symptoms of allergies may be different based on the kind of allergy and the sensitivity of the person. A correct diagnosis and professional advice can aid in the treatment and management of allergies.

Common Allergy Symptoms

Depending on the type of allergy and the allergen involved, common allergy symptoms may include:

• Nasal allergies: Sneezing, stuffy nose, runny nose, and an itchy and irritated nose.

• Allergic conjunctivitis: An allergic reaction of the eyes that causes eye itchiness, watering, redness, and irritation.

• Skin allergy symptoms: Hives, itching, redness, swelling or skin irritation.

• Allergic asthma: Coughing, wheezing, chest tightness or difficulty breathing.

• Food allergies: Nausea, vomiting, abdominal discomfort or diarrhoea.

A severe allergic reaction (anaphylaxis) may occur in some cases. Symptoms include difficulty breathing, swelling of the throat or tongue, dizziness, or a sudden drop in blood pressure. Anaphylaxis is a medical emergency that must be treated immediately.

Allergy Treatment Options

The treatment for an allergy is dependent on the type of allergy and the severity of it. Treatment can be aimed at symptom control, avoidance of triggers, and the control of allergic responses.

• Antihistamines: These drugs may be used to alleviate symptoms like itching, hives, runny nose, and sneezing.

• Nasal corticosteroids (corticosteroids): These can be used to decrease inflammation and congestion in the nose due to allergic rhinitis.

• Decongestants: These can temporarily relieve nasal congestion if used correctly.

• Mast cell stabilizers: Some drugs can help keep inflammatory substances from being released, which are related to allergies.

• Allergen immunotherapy: Immunotherapy (shots) or sublingual immunotherapy (under the tongue) may be recommended for certain allergies such as some pollen, dust mite, mould, and insect allergies.

• Epinephrine: Epinephrine should be used as directed by a health care professional and is the first-line treatment for anaphylaxis.

Allergy Prevention and Management

It is important to recognize and steer clear of known allergy causes when managing allergies. Preventive actions will vary based on the allergy, such as using dust-mite resistant mattresses, avoiding certain food allergens, minimizing exposure to pet allergens, keeping indoor environment clean, and taking care to prevent insect stings.

People at risk of severe allergic reactions may be advised by their healthcare professional to carry an epinephrine auto-injector and have an emergency action plan.

If you experience any of the following symptoms, it is time to seek advice from an allergy specialist:

Allergic reactions that return or happen without warning can interfere with being able to do everyday activities or sleep, as well as make it difficult to work and enjoy life. An allergy specialist can help determine if there are triggers and a management plan if symptoms persist or are hard to control.

Conclusion

Allergies are very common diseases that affect the nose, eyes, skin, breathing system, or even the stomach. Many people can control their allergic symptoms with the proper diagnosis, avoiding triggers, medication, and, when appropriate, immunotherapy.

Proper allergy evaluation by a healthcare professional is crucial if you have a severe or persistent reaction to allergens, to decide upon the correct allergy treatment and management.
