What is Persistent cough?

Persistent cough is a cough that lasts for an extended period of time, usually lasting for more than eight weeks in adults or more than four weeks in children. It is a symptom of an underlying condition or respiratory disorder, rather than a standalone illness. Some common causes of persistent cough include asthma, allergies, chronic bronchitis, gastroesophageal reflux disease (GERD), postnasal drip, and respiratory infections such as the common cold or pneumonia. It is important to identify and treat the underlying cause of the cough to alleviate symptoms and prevent any potential complications.

Understanding Persistent cough

A persistent cough is a cough that lasts for an extended period of time, typically for more than two to three weeks. It is often characterized by coughing spells that occur frequently throughout the day and night.

There are several causes of a persistent cough, including:

1. Respiratory infections: Coughing can be a symptom of various respiratory infections, such as the common cold, flu, bronchitis, or pneumonia.

2. Allergies: Allergic reactions to triggers such as dust, pollen, pet dander, or certain foods can lead to a persistent cough.

3. Asthma: In people with asthma, a persistent cough may be a sign of airway inflammation and bronchial constriction.

4. Gastroesophageal reflux disease (GERD): Acid reflux can cause irritation in the throat and lead to a chronic cough.

5. Postnasal drip: When mucus drips down the back of the throat, it can cause irritation and trigger a persistent cough.

6. Chronic obstructive pulmonary disease (COPD): This condition, which includes chronic bronchitis and emphysema, can cause a persistent cough along with other respiratory symptoms.

7. Smoking: Cigarette smoke can irritate the airways and cause a persistent cough in smokers.

It is important to seek medical attention if you have a persistent cough, as it could be a symptom of an underlying condition that needs to be treated. A healthcare professional can help diagnose the cause of your cough and develop an appropriate treatment plan.

Causes of Persistent cough

A persistent cough can have various causes, including:

1. Respiratory Infections: Viral or bacterial infections such as the common cold, bronchitis, or pneumonia can lead to a cough that persists even after other symptoms have resolved.

2. Allergies: Allergic reactions to substances like pollen, dust mites, pet dander, or certain foods can trigger a chronic cough.

3. Asthma: Chronic inflammation of the airways can cause coughing, wheezing, and difficulty breathing.

4. Gastroesophageal Reflux Disease (GERD): Acid reflux can irritate the throat and cause a persistent cough, particularly at night.

5. Postnasal Drip: Excessive mucus production due to allergies, sinus infections, or colds can cause a cough as the mucus drips down the back of the throat.

6. Chronic Obstructive Pulmonary Disease (COPD): Conditions like emphysema or chronic bronchitis can lead to a persistent cough and difficulty breathing.

7. Medications: Certain medications, such as angiotensin-converting enzyme (ACE) inhibitors used for high blood pressure, can cause a persistent cough as a side effect.

8. Smoking: Long-term smoking can damage the lungs and contribute to a chronic cough.

9. Environmental Factors: Exposure to irritants like pollution, smoke, chemicals, or strong odors can trigger a persistent cough.

10. Lung Cancer: While it is a less common cause, persistent cough can be a symptom of lung cancer. If the persistent cough is accompanied by other concerning symptoms, such as weight loss, chest pain, or difficulty breathing, it is important to seek medical evaluation.

It is important to consult a healthcare professional for proper diagnosis and treatment if experiencing a persistent cough.
