Why do you have to wear compression socks?

Compression socks are used to help diminish the risk of a clot in the legs.  This is one method of diminishing the risk.

Thank you for your question.  I appreciate your concern.
The not so obvious reason for wearing compression stockings after tummy tucks, liposuction, BBL and other surgeries not directly involving the lower extremity is to limit the risk for DVT (deep venous thrombosis or blood clot) that begins typically in your calves and may wind up in your lungs as a PE (pulmonary embolus) or elsewhere.  It happens when there is increased pressure in the veins in your pelvis or legs, such as from being overweight, smoking, BCP, pregnancy, varicose veins, or even from long surgeries. Any event that slows the flow of blood in a deep vein due to lack of movement can produce a DVT and that portends serious consequences.  Prophylaxis against lower extremity thrombosis starts with a preoperative assessment of the patient's risk for DVT and assignment of an assessment score, then compression socks but more likely sequential compression devices are attached to the calves in the operating room. Postoperatively, in addition to compression hosiery, walking and pointing toes away from and back to your nose while in bed, hydration, and even anticoagulants may be recommended.
