Allergy and asthma are among the most common health problems. Many Americans have asthma, seasonal hay fever, or other allergy-related conditions.
Some allergies, such as a mild case of hay fever, may not require any treatment or may be controlled with the occasional use of over-the-counter medications.
Others may interfere with your day-to-day activities, lower your quality of life, or even become life-threatening. In these cases, you should see a health care provider to help you manage allergies and their symptoms.
