When you have asthma, it's important to know the symptoms of trouble breathing, such as breathing faster than normal or using your chest and belly muscles to breathe. Follow your asthma action plan to know what to do.

When you have trouble breathing, your symptoms may be mild, moderate, or severe.

• Symptoms of mild trouble breathing include:
  • Breathing slightly faster than normal.
  • Normal skin color.
  • Breathlessness while walking.
• Symptoms of moderate trouble breathing include:
  • Breathing faster than normal.
  • Tiring quickly when you talk or eat. You may have to catch your breath during eating.
  • Using your belly muscles to help you breathe. Your belly moves in instead of out when you breathe in.
  • Skin color—especially on your face, hands, and feet—is pale to slightly gray or is a lace-like purple and pale pattern (mottled). But your tongue, gums, and lips remain pink.
  • Taking breaths after speaking in short phrases.
• Symptoms of severe trouble breathing include:
  • Breathing very fast. Children usually grunt with each breath. When you're short of breath, it can make it hard to speak smoothly. Speaking requires taking a breath after each word.
  • Appearing anxious and being unable to eat because it's too hard to breathe.
  • Using your neck, chest, and belly muscles to breathe. The skin between your ribs pulls in with each breath. You also may open your nostrils wide when you breathe in.
  • Taking longer than usual to breathe out and sometimes having a high-pitched, musical sound when you breathe in.
  • Sitting up, leaning forward, or sitting with your nose tilted up as if sniffing the air.
  • Skin color that is persistently pale, gray, bluish, or mottled, including the tongue, lips, earlobes, and nail beds.
