Can the condition thrombosis occur in someone who is immobile?

Yes, thrombosis can occur in someone who is immobile. Prolonged immobility, such as during long flights, bed rest, or after surgery, can lead to reduced blood flow and increased clotting risk in the veins, particularly in the legs, resulting in deep vein thrombosis (DVT). Factors such as age, obesity, and certain medical conditions can further elevate this risk. Regular movement or the use of compression devices can help mitigate this risk.
