Common signs and symptoms of asthma include:
Not all people who have asthma have these symptoms. Likewise, having these symptoms doesn't always mean that you have asthma. The best way doctors have to diagnose asthma is to use a lung function test, ask about medical history (including type and frequency of symptoms), and do a physical exam.
The type of asthma symptoms you have, how often they occur, and how severe they are may vary over time. Sometimes your symptoms may just annoy you. Other times, they may be troublesome enough to limit your daily routine.
Severe symptoms can be fatal. Thus, treating symptoms when you first notice them is important, so they don’t become severe.
With proper treatment, most people who have asthma can expect to have few, if any, symptoms either during the day or at night.
Many things can trigger or worsen asthma symptoms. Your doctor will help you find out which things (called triggers) may cause your asthma to flare up if you come in contact with them. Triggers can include:
Other health conditions can make asthma harder to manage. Examples of these conditions include a runny nose, sinus infections, reflux disease, psychological stress, and sleep apnea. These conditions should be treated as part of an overall asthma care plan.
Asthma is different for each person. Some of the triggers listed above may not affect you. Other triggers that do affect you might not be on the list. Talk with your doctor about the things that seem to make your asthma worse.
Hard to breathe: NHLBI researchers seek treatments for severe asthma
May is Asthma Awareness Month. Together we can help control asthma. During Asthma Awareness Month the National Asthma Education and Prevention Program (NAEPP) encourages you to discover how. Visit the NACI’s WAD Web page for more asthma related info.
Join the NHLBI's Asthma Awareness Twitter Chat with U.S. News on May 14 from 2:00-3:00 p.m. EDT. Other participants include representatives from the Office of the Surgeon General, the Centers of Disease Control and Prevention, the University of Wisconsin, and the American Thoracic Society. Follow the chat using the #AsthmaChat hashtag.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. To find clinical trials that are currently underway for Asthma, visit www.clinicaltrials.gov.
Visit Children and Clinical Studies to hear experts, parents, and children talk about their experiences with clinical research.

NHLBI Media Availability: Vitamin D supplementation does not reduce asthma treatment failure in people with low Vitamin D, but some benefits suggested.
Supplementing inhaled corticosteroids (ICS) with vitamin D does not reduce the rate of treatment failure in patients with asthma and vitamin D insufficiency, finds a new NIH-funded study. The Vitamin D Add-on Therapy Enhances Corticosteroid Responsiveness in Asthma (VIDA) trial randomized 408 adults with low vitamin D and mild/moderate asthma to receive the ICS ciclesonide supplemented with either high-dose vitamin D3 or placebo.
The NHLBI updates Health Topics articles on a biennial cycle based on a thorough review of research findings and new literature. The articles also are updated as needed if important new research is published. The date on each Health Topics article reflects when the content was originally posted or last revised.
