Regarding the issue of persistent coughing?

Hello Dr.
Zhou, I would like to ask you about a problem related to the thoracic cavity.
Here’s the situation: my father has been coughing for almost four months now.
However, he has not been able to get better despite visiting several hospitals.
The condition seems to improve significantly for a few days when he changes medications, but then the same medication becomes ineffective.
We have been traveling between northern and southern Taiwan without any improvement.
About three months ago, my father had an X-ray, which showed no abnormalities.
We also asked the doctors if it could be whooping cough or tuberculosis, but they ruled those out since they are contagious and no family members have shown any signs of infection.
Previous doctors prescribed regular cold medications, and the most recent doctor speculated that my father's long-term use of antihypertensive medication might have led to throat irritation.
We switched to another medication, but after two days, there was no improvement.
Continuing to cough like this could cause significant damage to his lungs.
Recently, I started looking for medical articles because I am very worried that my father might have an incurable disease.
However, there is no relevant family history; everyone is very healthy.
I don’t want to jump to conclusions.
Today seems to be the worst day for my father; he coughed so much that he vomited his lunch.
We feel utterly helpless.
What can we do to alleviate his suffering? Is it common for patients to cough for more than four months? Here are some related symptoms: 1.
My father is about 62 years old, 165 cm tall, and weighs 70 kg, with obesity.
2.
He has been taking antihypertensive medication for a long time.
3.
His cough is mostly dry, with occasional phlegm.
As you know, we have nowhere else to turn for help.
Could you please provide some advice? I am very concerned...
Thank you very much for your assistance.

Hello: There are many causes of chronic cough that require differential diagnosis; common ones include chronic bronchitis, bronchiectasis, tuberculosis, and cancer.
Additionally, non-pulmonary diseases may also be responsible, such as rhinitis with post-nasal drip, side effects from specific antihypertensive medications, and heart failure.
It is recommended to bring your antihypertensive medication (preferably with the medication name) to a pulmonologist for evaluation to clarify the cause.
Sincerely, Dr.
Chou Tzu-Kuang, Attending Physician, Department of Internal Medicine, Chest Hospital, Department of Health.

More Info

Persistent cough lasting for four months can be a challenging and concerning issue, especially when it is accompanied by symptoms such as vomiting due to coughing. It is understandable that you feel anxious about your father's health, particularly given the lack of a clear diagnosis despite multiple consultations. Here are some insights and recommendations based on medical knowledge that may help you navigate this situation.

Possible Causes of Persistent Cough
1. Chronic Bronchitis: This condition is characterized by a persistent cough that produces mucus. It is often caused by smoking or long-term exposure to irritants. Given your father's age and medical history, this could be a possibility.

2. Asthma: Asthma can cause a chronic cough, especially if it is triggered by allergens or irritants. If your father has a history of allergies or respiratory issues, this might be worth considering.

3. Gastroesophageal Reflux Disease (GERD): GERD can lead to a chronic cough due to acid irritating the throat. If your father experiences heartburn or regurgitation, this could be a contributing factor.

4. Postnasal Drip: Allergies or sinus infections can lead to postnasal drip, which can cause a persistent cough. If your father has any nasal congestion or sinus issues, this could be relevant.

5. Medication Side Effects: Some medications, particularly those for high blood pressure like ACE inhibitors, can cause a chronic cough as a side effect. If your father is on such medication, it may be worth discussing alternatives with his doctor.

6. Infections: While initial tests may have ruled out conditions like tuberculosis or whooping cough, other infections (viral or bacterial) could still be at play, especially if the cough has persisted despite treatment.

7. Lung Conditions: More serious conditions, such as chronic obstructive pulmonary disease (COPD) or even lung cancer, could present with a persistent cough. Given your father's age and symptoms, it is crucial to rule these out.

Recommendations
1. Seek a Specialist: If you haven't already, consider consulting a pulmonologist (lung specialist) who can perform more specialized tests, such as a CT scan of the chest, pulmonary function tests, or even a bronchoscopy if necessary.

2. Review Medications: Discuss with your father's primary care physician the possibility that his blood pressure medication could be contributing to his cough. If he is on an ACE inhibitor, switching to a different class of medication might alleviate the cough.

3. Consider Allergy Testing: If allergies are suspected, an allergist can perform tests to identify potential triggers that could be causing the cough.

4. Lifestyle Modifications: Encourage your father to avoid known irritants such as smoke, strong odors, and allergens. Staying hydrated and using a humidifier may also help soothe his throat.

5. Monitor Symptoms: Keep a detailed record of your father's symptoms, including when the cough worsens, any associated symptoms (like fever or weight loss), and how it affects his daily life. This information can be invaluable for healthcare providers.

6. Emergency Care: If your father experiences severe symptoms such as difficulty breathing, chest pain, or significant vomiting, seek emergency medical attention immediately.

Conclusion
A persistent cough lasting four months warrants thorough investigation, especially given the distressing symptoms you described. While it is natural to worry about serious conditions, many causes of chronic cough are treatable. By seeking specialized care and exploring all potential avenues, you can help your father find relief and improve his quality of life. Remember, open communication with healthcare providers is key to navigating this challenging situation.
