Recommended Actions
Move every hour. Ankle pumps and short walks actively counter slow venous flow.
Check urine colour: pale yellow means adequate hydration; dark yellow means drink now.
Discuss your risk profile with a doctor. Compression stockings may be appropriate.
Elevated risk: anticoagulant medicines may be indicated. Do not adjust dose independently.
Seek emergency care if you experience: sudden leg swelling, chest pain, or unexplained breathlessness.
