1. What Are Blood Clots and Why Are They a Concern When Flying?
Blood clots, also known as thrombi, are clumps of blood that form in blood vessels. While clotting is a normal and necessary process to stop bleeding, clots can become dangerous when they form in the deep veins of the body, leading to a condition called deep vein thrombosis (DVT). When part of a DVT breaks off and travels to the lungs, it can cause a pulmonary embolism (PE), a potentially fatal condition. Flying increases the risk of blood clots due to prolonged immobility, low cabin pressure, and dehydration. Understanding these risks and knowing how to prevent them is crucial for frequent flyers and those with pre-existing risk factors.
1.1. What is Deep Vein Thrombosis (DVT)?
Deep vein thrombosis (DVT) is a condition where a blood clot forms in a deep vein, usually in the legs. The primary concern with DVT is that the clot can dislodge and travel through the bloodstream to the lungs, causing a pulmonary embolism (PE). According to the Centers for Disease Control and Prevention (CDC), approximately 900,000 people in the United States are affected by DVT each year.
1.2. What is Pulmonary Embolism (PE)?
Pulmonary embolism (PE) occurs when a blood clot travels to the lungs and blocks one or more pulmonary arteries. This blockage can reduce oxygen levels in the blood and damage the lungs, heart, and other organs. A severe PE can be life-threatening. Symptoms include shortness of breath, chest pain, coughing up blood, and a rapid or irregular heartbeat.
1.3. How Does Flying Increase the Risk of Blood Clots?
Flying can increase the risk of blood clots due to several factors:
- Prolonged Immobility: Sitting for long periods, especially in cramped conditions, reduces blood flow in the legs, making it easier for clots to form.
- Low Cabin Pressure: The lower air pressure in airplane cabins can decrease oxygen levels in the blood, potentially contributing to clot formation.
- Dehydration: The dry air in airplane cabins can lead to dehydration, thickening the blood and increasing the risk of clotting.
Research from the World Health Organization (WHO) indicates that the risk of DVT increases twofold or threefold after a long-haul flight.
2. Who Is Most at Risk of Developing Blood Clots While Flying?
Several factors can increase your risk of developing blood clots while flying. Recognizing these risk factors can help you take appropriate preventative measures. Those most at risk include individuals with a history of blood clots, genetic clotting disorders, recent surgeries, hormone therapy users, pregnant women, older adults, obese individuals, and those with certain medical conditions.
