Coughing is usually associated with common respiratory problems, but in rare and serious cases it can signal a pulmonary embolism (PE)—a blood clot that has traveled to the lungs. This condition often develops after deep vein thrombosis (DVT), when a clot forms in the deep veins of the legs. Factors such as long flights, prolonged inactivity, or the use of birth control pills and hormone treatments can increase the likelihood of clot formation. When the clot reaches the lungs, it blocks blood flow and creates a potentially life-threatening emergency.
The symptoms of pulmonary embolism can appear suddenly and may include persistent coughing, shortness of breath, sharp chest pain, and a rapid heartbeat. In some cases, the person may cough up blood, which is a strong warning sign. These symptoms can be mistaken for other illnesses, making it especially important to take them seriously.
If these signs occur alongside swelling, redness, or pain in one leg, DVT is a strong possibility and immediate medical attention is crucial. Pulmonary embolism requires urgent diagnosis and treatment to prevent severe complications. Quick action can save lives, making awareness of these symptoms essential for anyone at risk.
