What You Need to Know About the Risk of Blood Clots on Long Flights
Briefly

Long flights can heighten the risk of developing deep vein thrombosis (DVT), with reports indicating a low overall probability but higher risk for certain individuals. Specifically, those with conditions like lupus or Crohn's disease have a significantly increased chance of clot formation. Precautions, including flexibility in travel plans and addressing personal health factors, are essential. Experts suggest that understanding one's medical history can help mitigate risks during long air travel, particularly for those with inflammatory conditions that may predispose them to complications like pulmonary embolism.
One study found that most people are at risk for developing DVT on one out of every 4,656 long flights, which is a relatively low likelihood.
Patients with UC and Crohn's disease are two to three times more likely to get blood clots than the general population, highlighting the need for precautions.
