Overview
- Hay fever, also called allergic rhinitis, causes cold-like symptoms. These may include a runny nose, itchy eyes, congestion, sneezing and sinus pressure. But unlike a cold, hay fever isn't caused by a virus. Hay fever is caused by an allergic response to a harmless outdoor or indoor substance the body identifies as harmful (allergen). Common allerg...
Symptoms
- Hay fever symptoms can include: 1. Runny nose and nasal stuffiness (congestion) 2. Watery, itchy, red eyes (allergic conjunctivitis) 3. Sneezing 4. Cough 5. Itchy nose, roof of mouth or throat 6. Mucus that runs down the back of your throat (postnasal drip) 7. Swollen, bruised-appearing skin under the eyes (allergic shiners) 8. Extreme tiredness (fatigue), often due to poor sleep
Causes
- When you have hay fever, your immune system identifies a harmless airborne substance as being harmful. This substance is called an allergen. Your immune system is how your body protects itself, so it produces immunoglobulin E (IgE) antibodies to protect against this allergen. The next time you come in contact with the allergen, these antibodies signal your immune system to relea…
Risk Factors
- The following can increase your risk of developing hay fever: 1. Having other allergies or asthma 2. Having a condition called atopic dermatitis or eczema, which makes your skin irritated and itchy 3. Having a blood relative, such as a parent or sibling, with allergies or asthma 4. Living or working in an environment that constantly exposes you to allergens — such as animal dander or dust mit…

Cardiovascular Risk
- If you have a poorly-controlled cardiovascular disease you are more at risk of death if you have an episode of anaphylaxis.12People with cardiovascular disease who are taking beta-blockers or alpha-adrenergic blockers are at further risk if they develop anaphylaxis because those medications reduce the effects of epinephrine, which is given to stop the anaphylactic reaction.
