Symptoms – Asthma
What asthma can feel like, and how to know when to get help.
Asthma symptoms are different for everyone. They may not be there all the time. They often come in short episodes called asthma attacks, or during stretches when symptoms get worse.
What Asthma Can Feel Like
Symptoms can show up on their own or together.
Common Symptoms
- Coughing, often in fits or episodes.
- Wheezing, a whistling sound when breathing out.
- Shortness of breath or fast breathing (dyspnea).
- Chest tightness.
- Coughing, wheezing or breathlessness with exercise, or in the minutes after you stop.
Less Common Symptoms
- Feeling tired during the day, often from poor sleep caused by nighttime symptoms.
- Feeling weak or low on energy.
During An Asthma Attack
In an attack, symptoms get a lot worse. It can happen slowly or come on suddenly.
Signs Of An Attack
- Fast breathing (tachypnea).
- Wheezing.
- A long breath out, with trouble exhaling fully.
- Using extra muscles to breathe, like the shoulders or neck.
- Trouble speaking in full sentences.
- Tripod position, leaning forward with hands on the knees to help breathing.
When To Get Help
It is not always easy to know when to reach out. When in doubt, contact your doctor.
Knowing when to act can be tricky. You might not know you have asthma yet, your symptoms might feel like a long cold, or you might be unsure if your medication is still enough. Whenever you are uncertain, it is always best to contact your doctor.
Before An Asthma Diagnosis
- Coughing, shortness of breath, chest tightness, or wheezing that lasts longer than a usual cold.
- A long-lasting cold can sometimes be asthma, or another condition that needs medical attention.
After An Asthma Diagnosis
- Your doctor should tell you when to seek emergency care.
- Follow the asthma action plan your doctor gives you. It usually uses three zones to help you manage symptoms.
An Asthma Action Plan: A General Example
A simple way to picture how a plan can work.
This is only a general example, not personal medical advice. Every person’s asthma and history is different, so the zones, symptoms, and steps that are right for you can look different. Always follow the specific asthma action plan and instructions your own doctor gives you. If you are ever in doubt, treat it as an emergency.
Green Zone
- Symptoms are under control.
- If you keep slipping between green and yellow, your asthma may not be well controlled and should be reviewed by a doctor.
Yellow Zone
- Contact a doctor if symptoms get worse even when you follow your action plan.
- If you are not clearly better within one day, contact your doctor, and don’t wait if things are getting worse.
Red Zone (most serious)
- Seek emergency care right away, call 911 (or your local emergency number outside the US).
- Keep using your relief medication as your action plan says while you wait for help.
Severe Symptoms: When To Call 911
If your reliever inhaler is not helping, or any of these happen, get emergency help right away.
🚨 Call 911 if:
- Your reliever inhaler doesn’t help, or its effect wears off quickly.
- Severe shortness of breath, unable to speak in full sentences, with chest tightness.
- Shortness of breath even with very little activity.
- Lips or nails turning blue or gray.
- Nostrils flaring while breathing.
- Skin pulling in between the ribs with each breath (retractions).
- Symptoms getting worse quickly, including shortness of breath and wheezing.
- Extreme tiredness or feeling worn out.
If You Are With Someone Having an Attack
- If they become very drowsy, confused, or unresponsive, this is a medical emergency.
- If their reliever inhaler is not helping, treat it as an emergency too.
- Call 911 right away and stay with them until help arrives.
