Which travelers face higher blood clot risk?

Travel risk is a personal question before it is a general one. The documented list is short, and checking yourself against it takes a minute you can spend before booking.

Which travelers are at higher risk?

In its travel guidance on deep vein thrombosis, wwwnc.cdc.gov lists these situations. Having had a previous blood clot, a family history of blood clots, a known clotting disorder, and recent surgery, hospitalization, or injury.

What the list does and does not tell you

The list names who to look at, not how much risk each item adds, so we give no percentages. It also does not decide whether you should travel. If more than one item applies to you, that is a reason to ask a clinician before booking and not after. If you have had a recent procedure, ask whether it counts as recent surgery for your travel dates, since a New Baltimore clinic can answer that against your own chart. For what a clot actually involves, a guide to deep vein thrombosis explains the condition and its treatment.

Next steps: raise it at the follow-up visit

Bring your itinerary to the next follow-up and ask whether your history changes the plan. Many travelers also ask about leg support, and what to know about compression stockings gives you questions to ask about it.

The upkeep note

A risk factor you know about is cheap to manage. The expensive version is the one discovered after the trip, so count a pre-travel check as part of the price of any plan that involves long hours seated.
