Frequently Asked Questions (FAQs)

What are allergies?

• Allergies are exaggerated immune responses to substances that are generally harmless to most people. These substances, known as allergens, can trigger symptoms such as sneezing, itching, and swelling.

What are common allergens?

• Common allergens include pollen, dust mites, pet dander, mold spores, certain foods (such as nuts, shellfish, and dairy), insect stings, and certain medications.

How are allergies diagnosed?

• Allergies are diagnosed through a combination of medical history, physical examination, and allergy testing, which may include skin prick tests, blood tests, or patch tests.

What is anaphylaxis?

• Anaphylaxis is a severe allergic reaction that can be life-threatening. It typically involves multiple organ systems and can cause symptoms such as difficulty breathing, rapid heartbeat, swelling of the throat, and loss of consciousness. It requires immediate medical attention.

Can allergies develop at any age?

• Yes, allergies can develop at any age. While some allergies may develop in childhood, others may not become apparent until adulthood.

What is immunotherapy?

• Immunotherapy, also known as allergy shots or allergy immunotherapy, is a treatment that involves gradually introducing small amounts of allergens to a patient's immune system to decrease sensitivity over time. It is often used to treat allergic rhinitis, allergic asthma, and insect sting allergies.

Are there any side effects of allergy shots?

• While allergy shots are generally safe, they can cause side effects such as redness or swelling at the injection site, itching, or worsening of allergy symptoms. Serious reactions are rare but can occur.

Can allergies be prevented?

• While allergies cannot always be prevented, there are steps that can be taken to reduce exposure to allergens and minimize symptoms. These may include using air purifiers, regularly cleaning the home to reduce dust and mold, avoiding known allergens, and taking medications as prescribed.

What is the difference between allergies and intolerances?

• Allergies involve the immune system's reaction to specific substances, while intolerances typically involve difficulty digesting certain foods or substances. Allergies often trigger immune responses that can affect multiple organ systems, while intolerances primarily affect the digestive system.

When should I see an allergist?

• You should consider seeing an allergist if you experience persistent or severe allergy symptoms, have a history of anaphylaxis, need help managing allergies or asthma, or require allergy testing to identify specific triggers. An allergist can provide personalized treatment and management strategies tailored to your needs.
