A persistent cough can be a frustrating and sometimes overlooked symptom for people living with Sjögren’s. While dry eyes and dry mouth are among the most recognized features of the disease, Sjögren’s can also affect the respiratory system and airways. In some cases, a chronic cough may be one of the earliest signs of respiratory involvement.
Why does Sjögren’s cause a persistent cough?
Sjögren’s can affect the moisture-producing glands and tissues throughout the body, including those of the respiratory tract. Dryness of the airways, sometimes referred to as xerotrachea, may contribute to a persistent dry cough. However, not every cough in someone with Sjögren’s is caused by airway dryness alone.
Respiratory symptoms may also be related to conditions affecting the larger or smaller airways, including:
- Airway dryness and irritation
- Bronchitis or bronchiolitis
- Bronchiectasis
- Asthma or asthma-like airway disease
- Chronic obstructive pulmonary disease (COPD)
- Interstitial lung disease
- Pulmonary hypertension
- Respiratory infections
For this reason, a persistent cough should not automatically be assumed to be “just part of Sjögren’s.” A proper assessment is important to determine the underlying cause.
How common is cough in Sjögren’s?
Chronic cough is a common complaint among people with Sjögren’s. It may occur even when there is no obvious lung disease and can sometimes be the symptom that leads to further investigation of respiratory involvement.
A cough that continues for weeks or months, particularly when accompanied by shortness of breath, wheezing, repeated chest infections, fatigue, or a change in exercise tolerance, should be discussed with a healthcare professional.
Investigating a persistent cough
Because there are many possible causes, healthcare providers may consider a number of investigations. These can include a review of symptoms and medical history, pulmonary function tests, chest imaging such as a CT scan, and other testing when appropriate.
It is also important to consider causes of chronic cough that may not be directly related to Sjögren’s, such as asthma, reflux, upper airway conditions, infections, or medication side effects.
Treatment depends on the cause
There is no single treatment for chronic cough in Sjögren’s. Management depends on what is causing the cough.
For some people, improving airway hydration and addressing dryness may provide some relief. Others may require treatment for an underlying airway or lung condition. Bronchodilators, inhaled therapies, treatment for infections, airway clearance techniques, or other medications may be considered depending on the diagnosis.
People with bronchiectasis may experience a persistent productive cough and can be more susceptible to respiratory infections. Management may include obtaining sputum samples to identify specific infections and using strategies to help clear excess mucus from the airways. These approaches may include airway clearance devices, nebulized saline, bronchodilators, or other treatments recommended by a healthcare provider.
When small airway disease such as bronchiolitis is suspected, further assessment may be necessary to determine the extent of lung involvement and the most appropriate treatment.
Don’t ignore a cough that persists
A chronic cough can have a significant impact on daily life, affecting sleep, conversations, work, social activities, and overall quality of life. It can also be a sign of an underlying respiratory condition that deserves attention.
If you have Sjögren’s and develop a cough that does not go away, speak with your healthcare provider. Persistent or worsening symptoms should be evaluated, particularly if you experience shortness of breath, chest discomfort, wheezing, repeated respiratory infections, coughing up blood, or a noticeable decline in your ability to be active.
While a persistent cough may sometimes be related to dryness of the airways, it is important to investigate other possible causes. Understanding what is behind the cough is the first step toward finding the most appropriate treatment and protecting your respiratory health.
