Causes, Symptoms, Diagnosis, and Treatment

Allergies are a common affliction affecting millions worldwide. Understanding the basics can help in effective management and treatment. This guide is tailored for laypeople and patients seeking a deeper grasp on this prevalent condition.

Etiology (Causes) of Allergies

Allergies occur when the body's immune system reacts to a substance (allergen) as though it was a harmful pathogen, like a virus or bacterium. Common allergens include:

• Pollen
• Dust mites
• Mold spores
• Pet dander
• Food items such as peanuts, milk, and shellfish

Symptoms of Allergies

When exposed to an allergen, individuals may experience a variety of symptoms, including:

• Runny or stuffy nose
• Sneezing
• Itchy or watery eyes
• Rash or hives
• Shortness of breath or wheezing
• Swelling of the face or lips

Diagnosis of Allergies

If you suspect you have an allergy, it is vital to see a healthcare professional. Diagnosis typically involves:

1. Medical History: Discussing your symptoms and potential allergen exposures.
2. Skin Test: Small amounts of suspected allergens are applied to the skin using a tiny needle.
3. Blood Test: To measure the amount of allergy-causing antibodies in your system.

Treatment of Allergies

While allergies cannot be cured, they can be managed. Treatment options include:

• Antihistamines to reduce symptoms
• Nasal corticosteroids for nasal congestion
• Decongestants for congestion and swelling
• Allergy shots (immunotherapy) for long-term relief
• Avoidance of known allergens

It's essential to work with a healthcare professional to determine the best treatment approach for your specific allergies.
