Asthma (Az-muh) is a chronic disease that affects your airways in lungs. Common asthma symptoms include:

  1. Coughing. Coughing from asthma is often worse at night or early in the morning, making it hard to sleep.
  2. Wheezing. Wheezing is a whistling or squeaky sound when you breathe.
  3. Chest tightness. This can feel like something is squeezing or sitting on your chest.
  4. Shortness of breath. Some people say they can't catch their breath, or they feel breathless or out of breath. You may feel like you can't get enough air in or out of your lungs.
  5. Faster breathing or noisy breathing
