what causes deep vein thrombosis - #26577
I am feeling a bit worried and need some insights. A few weeks ago, I had this really long flight and afterward my leg started swelling up and felt kind of achy. I honestly thought I just needed to stretch or something, but it didn’t go away. I went to my doc and they told me it might be deep vein thrombosis. What causes deep vein thrombosis, right? I mean, I’ve been pretty active, but sitting for hours without moving has me thinking. They mentioned things like blood clots but didn't really explain what causes deep vein thrombosis. It’s like, could it just be because of the flight? Or am I missing something bigger? My family has a history of circulation problems, so now I’m even more curious about what causes deep vein thrombosis, and if that runs in families or if it’s more common in certain situations. I heard about compression socks and elevating the leg but is that really enough? What causes deep vein thrombosis in people who don’t seem at high risk? I’m just trying to understand if I should be worried or take any extra steps to avoid this in the future. Any help would be super appreciated!

Doctors' responses
You’re right to look into this further—deep vein thrombosis (DVT) can indeed be serious. It’s essentially caused by a blood clot forming in a deep vein, typically in the legs. This can happen when blood flow is slowed or stopped, which is why extended periods of immobility, like during a long flight, are often implicated. When you’re sitting for a while without much movement, blood can pool in the legs, and if it doesn’t move along smoothly, it can form a clot. There are several factors that might increase the risk besides long flights. These include family history of blood clots, certain genetic disorders affecting clotting, prolonged bed rest (like after surgery or illness), and lifestyle factors like smoking or being overweight. Pregancy and the use of hormone replacement therapy or birth control pills can also elevate risk. It’s possible for active individuals to develop DVT if other risk factors are at play or in combination. You’ll often hear about preventative measures like staying hydrated, moving around regularly on flights, wearing compression stockings to encourage blood flow, and elevating your legs when possible. While these are good general practices, they are often part of a broader strategy to reduce risk. Given your family history and current symptoms, it’s crucial to follow up with your doctor to determine if further investigations or treatments, like anticoagulant medications, might be necessary. This is especially important if there’s any change in your symptoms, like increasing pain, warmth, or a change in color in the affected leg. If symptoms worsen quickly or if you develop new symptoms like chest pain or shortness of breath, these could be signs of a pulmonary embolism, which requires immediate medical attention. Consider discussing your personal and family medical history with your healthcare provider to get a comprehensive risk assessment and tailored advice on managing and reducing risk factors.
