Patient experiencing persistent cough for more than three weeks

Coughing is the body's natural means of clearing the airways of infections, mucus, and irritants. While most coughs resolve in a few days or weeks, a persistent cough lasting more than 3 weeks should not be ignored. It may indicate an underlying medical condition that requires medical attention. A persistent cough is sometimes dismissed as a minor issue, but delaying diagnosis can lead to long-term pain and issues.

Dr Pravalika Reddy specialises in diagnosing and treating the underlying conditions responsible for chronic respiratory symptoms, helping patients achieve lasting relief and better health.

Take Control of Your Respiratory Health

Common Causes of a Persistent Cough

A persistent cough can be brought on by a number of medical issues. For long-term alleviation and effective therapy, the precise cause must be determined.

1. Post-Viral Cough

After recovering from a viral infection such as the flu or common cold, some individuals continue to experience a Persistent Cough for several weeks.

This occurs because:

  • Airways remain inflamed
  • The cough reflex becomes more sensitive.
  • Mucus production may continue temporarily.

Although symptoms usually improve over time, prolonged coughing should still be evaluated.

Don't let a lingering cough affect your life—consult Dr Pravalika Reddy today.

2. Asthma

Asthma is one of the most common causes of a Persistent Cough, particularly when coughing occurs at night or after exercise.

Symptoms may include:

  • Wheezing
  • Shortness of breath
  • Chest tightness
  • Recurrent coughing episodes

In some cases, coughing may be the only noticeable symptom of asthma.

3. Acid Reflux (GERD)

Many people are surprised to learn that digestive problems can cause a Persistent Cough.

When stomach acid flows back into the oesophagus, it can irritate the throat and trigger coughing.

Signs of reflux-related cough include:

  • Sour taste in the mouth
  • Heartburn
  • Throat irritation
  • Cough worsening after meals.

Treating acid reflux often helps reduce coughing symptoms.

4. Allergies and Postnasal Drip

Allergies can cause excess mucus production, leading to postnasal drip. This occurs when mucus drips down the back of the throat, triggering a Persistent Cough.

Common allergy triggers include:

  • Dust mites
  • Pollen
  • Pet dander
  • Mold

Patients often experience throat clearing, nasal congestion, and coughing that worsens at night.

5. Chronic Bronchitis

Chronic bronchitis is a long-term lung condition often associated with smoking or prolonged exposure to irritants.

Symptoms include:

  • Daily cough
  • Excess mucus production
  • Shortness of breath
  • Frequent respiratory infections

A Persistent Cough caused by chronic bronchitis requires professional management to prevent complications.

6. Respiratory Infections

Certain infections may cause coughing that continues long after the initial illness has resolved.

Examples include:

  • Pneumonia
  • Whooping cough
  • Tuberculosis
  • Chronic sinus infections

These conditions can result in a Persistent Cough and often require targeted treatment.

Early diagnosis leads to better outcomes—schedule your respiratory assessment today.
