Is Your Cough a Sign of Altitude Sickness or Something Else? - Family Medicine

---

Based on your description, it sounds like you are experiencing a combination of symptoms that could potentially be related to altitude sickness, but there are also other possibilities to consider, such as a respiratory infection or even an allergic reaction. Let's break down your symptoms and explore the potential causes.


Symptoms Overview
1. Shortness of Breath and Chest Discomfort: These symptoms can be common at higher altitudes due to lower oxygen levels. When you exert yourself, such as climbing stairs, your body may struggle to get enough oxygen, leading to feelings of breathlessness and chest tightness. However, if these symptoms are severe or accompanied by pain, it could indicate a more serious issue.

2. Coughing: The dry cough you mentioned, especially if it produces white phlegm, could be a sign of irritation in your airways. This could be due to altitude, where the air is drier, or it could indicate a respiratory infection, especially if it persists after descending from the mountain.

3. Difficulty Breathing While Lying Down: This symptom can be concerning. It may suggest fluid in the lungs or other respiratory issues, which can be exacerbated by altitude.
4. Duration of Symptoms: Since your cough has persisted even after returning to a lower altitude, it raises the possibility of an underlying condition that may need medical attention.


Potential Causes
1. Altitude Sickness: Acute Mountain Sickness (AMS) can occur when you ascend to high altitudes too quickly. Symptoms include headache, nausea, dizziness, and shortness of breath. Coughing is less common but can occur due to the dry air and increased respiratory effort.

2. Respiratory Infection: If you have been exposed to cold air or other irritants, you might be developing a cold or another respiratory infection. The presence of phlegm can indicate that your body is trying to clear out mucus from your airways.

3. Allergic Reaction: If you have allergies, exposure to different environmental factors at a higher altitude could trigger symptoms like coughing and shortness of breath.


When to Seek Medical Attention
Given the combination of your symptoms—especially the chest discomfort, persistent cough, and difficulty breathing while lying down—it is advisable to seek medical attention. You should consider visiting a healthcare provider who specializes in respiratory issues, such as a pulmonologist. If you are unable to see a specialist, a general practitioner or an urgent care facility can also evaluate your symptoms.


What to Expect During a Medical Evaluation
During your visit, the healthcare provider will likely:
- Take a detailed history of your symptoms, including their onset, duration, and any associated factors (like recent travel to high altitudes).

- Perform a physical examination, focusing on your respiratory system.

- Possibly order diagnostic tests, such as a chest X-ray or pulmonary function tests, to assess your lung function and rule out other conditions.


Conclusion
While altitude sickness is a possibility, your ongoing symptoms after returning to a lower altitude suggest that there may be another underlying issue at play. It is essential to get a proper evaluation to determine the cause of your symptoms and receive appropriate treatment. In the meantime, try to stay hydrated, avoid strenuous activities, and monitor your symptoms closely. If you experience worsening symptoms, such as severe chest pain, difficulty breathing, or high fever, seek emergency medical care immediately.
