Persistent Cough: Is It Asthma or Something Else?

Q: Persistent Cough: Is It Asthma or Something Else?

Hello： Although the current symptoms do not resemble an asthma attack, having been previously diagnosed with asthma, it is still necessary to have regular follow-ups and treatment with a pulmonologist!

Persistent cough that does not resolve?

Hello, doctor.
Last year, I experienced severe coughing that made me feel like vomiting, and I sought medical attention in the pulmonary department, where I was diagnosed with cough-variant asthma.
After using the medication prescribed by the doctor for a month, I did not have any recurrence.
Recently, for the past month, after meals, I have been feeling phlegm in my throat and have been coughing to clear it, but I cannot seem to expel it.
This lasts for 1-2 hours, and sometimes I cough so much that I feel like vomiting.
I would like to ask the doctor: Is this a recurrence of asthma? Can I continue using the asthma medication? Can cough-variant asthma be cured? Do I need to pay special attention during exercise like other asthma patients?

More Info

Persistent cough can be a frustrating and concerning symptom, especially when it disrupts daily life and sleep. Given your history of cough variant asthma, it is important to consider whether your current symptoms are related to that condition or if they are indicative of another underlying issue.

Cough variant asthma is a form of asthma where the primary symptom is a chronic cough, rather than wheezing or shortness of breath. This type of asthma can be triggered by various factors, including allergens, respiratory infections, cold air, and even exercise. The fact that you experienced a significant cough that led you to seek medical attention previously suggests that your airways may be sensitive or reactive.

Your recent symptoms of feeling like you have phlegm in your throat after eating, accompanied by a persistent cough that can lead to gagging, could indeed be related to your history of asthma. It is not uncommon for individuals with asthma to experience increased mucus production, especially if they have underlying allergies or if they are exposed to irritants. Additionally, gastroesophageal reflux disease (GERD) can also cause similar symptoms, where stomach acid irritates the throat and triggers a cough reflex.

In terms of management, it is advisable to continue using your prescribed asthma medication, such as the inhaler you mentioned (治喘樂), as long as it is effective and you are not experiencing any adverse effects. Asthma is a chronic condition, and while some individuals may experience periods of remission, it is not typically considered "curable." Instead, it is managed through medication and lifestyle adjustments.
Regarding exercise, individuals with cough variant asthma should indeed take precautions similar to those with classic asthma. This includes warming up before exercise, avoiding triggers such as cold air or allergens, and having a rescue inhaler on hand during physical activity. Regular exercise is beneficial for overall health and can improve lung function, but it is important to listen to your body and modify activities if you experience symptoms.

It is also essential to monitor your symptoms closely. If your cough persists or worsens, or if you experience new symptoms such as wheezing or shortness of breath, it would be prudent to consult your healthcare provider. They may recommend further evaluation, such as pulmonary function tests or allergy testing, to better understand your condition and tailor your treatment plan accordingly.

In summary, your current symptoms could be related to your history of cough variant asthma, but other factors such as allergies or GERD may also play a role. Continuing your asthma medication, being mindful of triggers, and maintaining open communication with your healthcare provider will be key in managing your symptoms effectively. If you have any concerns or if your symptoms change, do not hesitate to seek medical advice.
