An allergy is a reaction of your immune system to foreign substances, or allergens, that aren't ordinarily detrimental but are to some people. Certain foods, pollen, bee venom, or pet dander are examples.

Allergies occur frequently and vary in severity from person to person and can range from moderate annoyance to anaphylaxis, a potentially fatal emergency. While most allergies are incurable, some therapies can help alleviate allergy symptoms.

Causes of Allergies

Antibodies are chemicals produced by your immune system. When you have allergies, your immune system produces antibodies that mistakenly label a harmless allergen as hazardous. When your body comes into contact with something like pet dander, for example, it should recognize that it is innocuous. The immune system targets dander allergies because it views it as an outside invader posing a threat to the body. Your immune system's reaction to the allergen can inflame your skin, sinuses, airways, or digestive tract when you come into touch with it.

It is the mission of your immune system to keep you healthy by battling hazardous microorganisms. It accomplishes this by attacking anything that it believes poses a threat to your health. This reaction might include inflammation, sneezing, and various other symptoms, depending on the allergen.

Treatment for Allergies

If you experience symptoms that you believe are caused by an allergy and over-the-counter allergy drugs aren't providing adequate relief, you should consult a doctor. If you experience side effects after starting a new medicine, contact the doctor who recommended it as soon as possible.

Make an appointment with your doctor if you've ever had a severe allergic reaction or any signs and symptoms of anaphylaxis. Anaphylaxis is complicated, so you'll need to see a specialist specializing in allergies and immunology for evaluation, diagnosis, and long-term care.
