10 Blood Clot in Lung Symptoms
Reviewed: Dr. Gromatzky
Symptom #7: Cough
A cough is a protective and repetitive reflex where it functions to clear the airways from foreign particles, irritants, and microbes. While a cough can occur in normal conditions, frequent coughing indicates that there is underlying disease. From an evolutionary perspective, viruses and bacteria may benefit from coughing as it helps to spread the disease to other potential hosts.
Some conditions that can cause frequent coughing include smoking, air pollution, choking, post-nasal drip, lung tumors, chronic bronchitis, heart failure, and pulmonary embolism (blood clot in the lung).
