Dear Miss Yu-Juan,
There are many reasons for a persistent cough.
According to statistics, common causes include side effects from medications, post-nasal drip, gastroesophageal reflux disease (GERD), and asthma.
For example, angiotensin-converting enzyme inhibitors (ACEIs), which are used for blood pressure management, can cause a cough as a side effect in some patients.
Another potential cause—post-nasal drip—often presents with the patient feeling mucus running down the throat, such as frequent throat clearing or worsening cough when lying down, which may suggest that post-nasal drip is the reason for the persistent cough.
In patients with gastroesophageal reflux disease, there is usually a burning sensation in the chest, a sour taste in the mouth, and worsening cough when lying down.
Additionally, if the patient experiences stomach pain when hungry that improves after eating, this may indicate gastrointestinal issues.
If the patient has a history of asthma, the cough may indicate poor control of asthma symptoms.
Conversely, if there is no history of asthma but the patient has allergic rhinitis, a family history of asthma, or a good response to corticosteroid treatment, we may suspect that the patient could be asthmatic.
In such cases, the physician would focus on treating the asthma.
Moreover, long-term smoking, lung tumors, or tuberculosis are also major causes of chronic cough.
In the outpatient management process, aside from inquiring about potential medication-related side effects, a chest X-ray should be arranged.
If there are any abnormal findings on the X-ray, further specialized tests will be scheduled to determine the cause and initiate treatment.
If the chest X-ray shows no significant abnormalities, the physician will often conduct detailed examinations for other potential causes.
At this point, the patient should also reflect on the environments that may trigger the cough, such as the workplace or riding a motorcycle without a mask.
Avoiding these irritants can effectively treat the cough, which cannot be achieved merely by taking medications.
Given the high prevalence of tuberculosis in Taiwan, chronic cough caused by Mycobacterium tuberculosis infection is another condition that requires special attention beyond the aforementioned four causes.
There are many other potential causes of chronic cough that cannot all be listed here.
Please consider the possible causes mentioned in this article along with your own symptoms, and consult an experienced pulmonologist for a thorough examination.
Sincerely,
Dr.

More Info

Persistent cough can be a frustrating and debilitating condition, especially when it lingers for weeks or even months. Understanding the underlying causes and exploring effective treatment options is crucial for relief. Here’s a comprehensive overview of potential causes, treatment strategies, and lifestyle modifications that can help alleviate your symptoms.

Understanding Persistent Cough
A persistent cough can arise from various factors, including:
1. Infections: Viral infections, such as the common cold or COVID-19, can lead to lingering coughs even after other symptoms have resolved. Bacterial infections, like bronchitis or pneumonia, may also be responsible.

2. Allergies and Asthma: Allergens such as pollen, dust mites, or pet dander can trigger coughing. Asthma, characterized by airway inflammation, can lead to chronic cough, especially at night or during physical activity.

3. Gastroesophageal Reflux Disease (GERD): Acid reflux can irritate the throat and lead to a chronic cough, particularly when lying down.

4. Chronic Bronchitis: This condition, often associated with smoking or long-term exposure to irritants, can cause a persistent cough with mucus production.

5. Postnasal Drip: Conditions like sinusitis can lead to mucus dripping down the back of the throat, triggering a cough.

Effective Treatment Strategies
1. Medications:
- Cough Suppressants: Over-the-counter medications like dextromethorphan can help reduce the urge to cough.

- Expectorants: Guaifenesin helps thin mucus, making it easier to expel.

- Antihistamines: If allergies are the cause, medications like cetirizine or loratadine can alleviate symptoms.

- Inhalers: For asthma-related coughs, bronchodilators or corticosteroid inhalers may be prescribed.

2. Antibiotics: If a bacterial infection is suspected, a healthcare provider may prescribe antibiotics. However, they are ineffective against viral infections.

3. Corticosteroids: In cases of severe inflammation, oral or inhaled corticosteroids may be recommended to reduce airway swelling.

4. Lifestyle Modifications:
- Hydration: Staying well-hydrated helps thin mucus and soothe the throat.

- Humidifiers: Using a humidifier can add moisture to the air, which may ease coughing, especially in dry environments.

- Avoid Irritants: Steering clear of smoke, strong odors, and allergens can help reduce coughing episodes.

- Dietary Changes: If GERD is a factor, avoiding spicy foods, caffeine, and large meals before bedtime can be beneficial.

5. Home Remedies:
- Honey: A spoonful of honey can soothe the throat and reduce coughing, especially in children over one year old.

- Warm Liquids: Herbal teas or warm broths can provide relief and comfort.

When to Seek Medical Attention
If your cough persists for more than three weeks, is accompanied by severe symptoms (such as high fever, difficulty breathing, or coughing up blood), or if you experience significant changes in your health, it’s essential to consult a healthcare professional. They may recommend further diagnostic tests, such as chest X-rays or pulmonary function tests, to determine the underlying cause.

Conclusion
Persistent cough can significantly impact your quality of life, but understanding its causes and exploring effective treatment options can lead to relief. It’s essential to work closely with a healthcare provider to identify the underlying issue and develop a tailored treatment plan. By combining medical interventions with lifestyle modifications, you can take proactive steps toward managing your symptoms and improving your overall health.
