4 Common Symptoms of Asthma And It’s Diagnosis
What Is Asthma?
Asthma is a chronic lung disease that inflames and narrows the airways. It causes recurring periods of wheezing (a whistling sound when you breathe).
Overview : The airways are tubes that carry air into and out of your lungs. People who have asthma have inflamed airways. The inflammation makes the airways swollen and very sensitive. The airways tend to react strongly to certain inhaled substances. When the airways react, the muscles around them tighten. This narrows the airways, causing less air to flow into the lungs. The swelling also can worsen, making the airways even narrower. Cells in the airways might make more mucus than usual. Mucus is a sticky, thick liquid that can further narrow the airways. This chain reaction can result in symptoms. Symptoms can happen each time the airways are inflamed.When symptoms get more intense and/or more symptoms occur, you’re having an asthma attack. That attacks also are called flareups or exacerbation . Treating symptoms when you first notice them is important. This will help prevent the symptoms from worsening and causing a severe attack. Outlook Asthma has no cure. Even when you feel fine, you still have the disease and it can flare up at any time.
