A lingering cough in kids is often blamed on a cold—but what if it doesn’t go away?
When a cough lasts for weeks or keeps coming back, asthma is one of the most common causes.
What Does an Asthma Cough Sound Like?
Asthma doesn’t always cause wheezing.
In many children, the main symptom is cough.
It often:
- Happens at night
- Gets worse with exercise
- Comes and goes over time
- Lingers after a cold
Common Signs Your Child’s Cough May Be Asthma
Watch for:
- Cough lasting more than 2–3 weeks
- Nighttime coughing
- Cough with running or playing
- Recurrent “bronchitis” or repeated cough illnesses
- Cough that improves with inhalers
When It’s Probably NOT Just a Cold
Most viral coughs improve within 1–2 weeks.
If your child:
- Keeps coughing after other symptoms are gone
- Seems fine during the day but coughs at night
- Has repeated episodes over months
…it’s worth looking deeper.
What Causes Asthma Cough?
Asthma causes inflammation and narrowing of the airways.
Triggers may include:
- Viral infections
- Allergies
- Exercise
- Weather changes
This leads to airway irritation—and cough.
How Is Asthma Diagnosed?
Diagnosis is based on:
- Symptom pattern
- Physical exam
- Response to treatment
- Breathing tests (in older children)
Sometimes, a trial of medication helps confirm the diagnosis.
What Happens If It Is Asthma?
The good news: asthma is very manageable.
Treatment may include:
- Inhalers (with spacer)
- Preventive medications
- Trigger control
The goal is simple:
👉 No nighttime symptoms, no activity limitations, and no frequent flare-ups
Bottom Line
Not every cough is asthma—but a persistent or recurring cough should not be ignored.
Early evaluation can make a big difference.
👉 If your child has a cough that won’t go away, schedule an evaluation at Texas Lung & Sleep.
