Allergies are reactions of the immune system to foreign substances, which are usually not harmful to the body. They can be caused by certain foods, pollen, or pet dander.
The immune system is tasked with protecting the body from pathogens by attacking any substance it perceives as harmful. In people with allergies, this reaction can cause symptoms such as inflammation, sneezing, or other symptoms.
Allergies are common and can affect health and quality of life. Their treatment may vary based on the type and severity of the allergy.
Symptoms of allergies include:
- Swelling
- Urticaria
- Nausea
- Fatigue
The types of allergies can be different such as food allergies, seasonal allergies, or severe allergies that can cause anaphylaxis.
Allergy treatment includes:
- Medicines to control symptoms such as antihistamines and corticosteroids
- Immunotherapy to help the body get used to the allergy
- Epinephrine for severe allergic reactions
Preventing allergies can be difficult, but avoiding potential allergens can help reduce symptoms. Allergy tests can help identify specific allergens for an individual and help design an effective treatment plan.
