3) Wheezing
Wheeze is a typical whistling sound that produces when air passes through congested, inflamed or blocked airways. The most common cause of wheeze is asthma or pneumonia followed by some other benign conditions of the lungs that are easily treatable.
However, wheezing can be due to the presence of cancer in the lungs as the cancerous mass can put pressure on the lung tissues and cause congestion or blockage of the airways. So don’t assume that your whistling sounds are due to allergies or asthma and let your doctor evaluate the root cause.
