The Signs and Symptoms of Asthma: Everything You Should Know

There are different types of asthma. Some types are defined by their causes, while others are defined by their symptoms. Also, asthma may often be categorized based on its severity or the age at which it first shows up. In some people, asthma is so mild and situation-specific that it doesn’t require medication. In others, it can be severely debilitating most or all the time.
“We sometimes call asthma a syndrome, not a disease, because it’s so complex,” explains Chitra Dinakar, MD, a clinical professor of medicine at Stanford University and the clinical chief of allergy, asthma, and immunodeficiency at Stanford Health Care.
Asthma can show up in many forms and for different reasons, Dr. Dinakar says. And it’s sometimes hard for doctors to predict how asthma will progress or evolve as a patient grows older. In some people, it gets worse over time. In others, it goes away. “It’s not an easily defined disease,” she says.
In understanding where your or someone else’s asthma fits on the spectrum of diagnoses, it’s helpful to know more about the common symptoms of asthma and asthma attacks — and when you can expect both to show up.
Common Symptoms of Asthma May Be Present Some or All of the Time in People With the Condition
- Shortness of breath or trouble breathing
- Coughing
- Chest tightness or pain
- A wheezing or whistling sound while breathing
Asthma symptoms develop when the lining of the bronchial tubes (airways) becomes inflamed, which is often in response to an environmental trigger, rather than symptoms that are continuously present.

Some Asthma Symptoms Are Only Present During an Asthma Attack
Wheezing This refers to a whistling or squeaky, almost musical sound during breathing.
Shortness of Breath This simply means feeling like you can’t get enough air into your lungs.
Rapid Breathing In response to not getting enough air in each breath, your body may speed up your rate of breathing.
Coughing A cough during an asthma attack may contain phlegm or may be dry.
Chest Tightness This can take the form of pain, pressure, or feeling like something is squeezing or sitting on your chest.
Severe Asthma Attacks Are Defined by These Symptoms
- Extreme breathing difficulties and heavy wheezing — the kind that makes it hard for you to finish a sentence
- The need to strain your chest muscles in order to breathe
- Symptoms that don’t get any better after you use an inhaler
- Uncontrollable coughing
- Sweating
- Rapid nostril movement
- Low peak flow readings when you use a peak flow meter
- Cyanosis (a condition in which the skin of your face, lips, or fingers turn blue)
- Your ribs or stomach suck in and push out dramatically as you breathe
- Your chest expanding, but not fully deflating as you exhale (a sign that air isn’t able to escape your lungs)

5 Foods That May Trigger Asthma Flares
Disrupted Sleep, Difficulty Exercising, and Other Signs You Might Have Asthma
Along with its short-term symptoms, asthma can cause other problems or disruptions.
Because symptoms often become worse at night, asthma can disrupt sleep or cause insomnia. Poor sleep, along with daytime asthma symptoms, can make it hard to complete work or school tasks, as well as day-to-day chores.

And remember, asthma symptoms do not look the same in everyone. “Each person with asthma is unique and so are their symptoms,” Dr. Dinakar says.
In some people with asthma, symptoms are very mild and seldom show up. In others, symptoms may be severe but situational, for example, after running hard or while going to bed. In others, symptoms are always around and may make everyday life difficult.
The important takeaway is that good management of symptoms and the right asthma treatment plan can help improve anyone’s asthma. Ask your doctor about an asthma action plan and follow it when symptoms flare up. Whatever your symptoms, it’s important to consult with a doctor to ensure that asthma is not disrupting your sleep, your health, or your life.
