What Is a PFT Test, and What Can It Tell Me About My Lung Health?

Question

My doctor recently recommended that I get a PFT test (Pulmonary Function Test) because I’ve been experiencing shortness of breath and occasional wheezing. I had never heard of this test before, so I’m trying to understand what it actually measures and what the results mean.

From what I’ve read, a PFT test checks how well the lungs are working by measuring airflow, lung volume, and oxygen exchange. But how do I know if my lung function is normal or if there’s a problem? What are the common conditions that a PFT test can diagnose—does it only detect asthma and COPD, or can it also find issues like lung infections or fibrosis?

Another thing I’m curious about is whether the test is uncomfortable. I read that you have to blow into a machine multiple times—does it make you feel lightheaded or short of breath? Also, do I need to do anything special to prepare for the test, like avoiding certain medications or foods?

Since I prefer a natural approach, I also started looking into Ayurveda’s perspective on lung health. Are there Ayurvedic treatments or breathing exercises (Pranayama) that can improve lung function before or after a PFT test? I found that Vasaka, Tulsi, and Mulethi are used for respiratory health—do these actually help strengthen the lungs?

For those who have had a PFT test, what was your experience? Did it help diagnose your symptoms accurately, and did you need further tests? I’d love to hear what to expect and how to support lung health naturally.

A Pulmonary Function Test (PFT) is a diagnostic tool that measures how well your lungs are functioning by assessing airflow, lung volume, and gas exchange. It can help detect conditions like asthma, chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, and other lung disorders. The test involves blowing into a machine multiple times, and although it can feel a bit strenuous, it generally doesn't cause significant discomfort. Some people might feel lightheaded or short of breath during the test, but this is temporary. Preparation typically involves avoiding heavy meals, certain medications, or smoking before the test, but your doctor will provide specific instructions. In Ayurveda, herbs like Vasaka, Tulsi, and Mulethi are often recommended for respiratory health due to their anti-inflammatory and bronchodilatory effects, which may help strengthen lung function. Additionally, Pranayama (breathing exercises) can improve lung capacity and overall respiratory function. For those who have had a PFT, the test is generally straightforward and helps provide insight into lung health, but it may be followed by additional testing if necessary. Supporting lung health with natural remedies, along with the results from the PFT, can help you manage your symptoms and improve overall function.
