Omega-3 fats function as an anticoagulant; what precaution is advised for individuals planning surgery?

• A. Increase fish oil intake before surgery
• B. Stop taking fish oil two weeks before surgery
• C. Double the fish oil dose one week before surgery
• D. Take vitamin C to counteract anticoagulation

Answer: (B)

Omega-3 fats can affect platelet function, acting to slow clot formation and potentially increase bleeding risk during and after surgery. Because their antiplatelet effects can persist for a while after stopping, a washout period of about one to two weeks before elective surgery helps allow platelet function to return toward normal. Stopping the supplement is the sensible precaution to reduce bleeding risk. Increasing intake or doubling the dose would raise anticoagulant effects and is not advised. Taking vitamin C does not counteract anticoagulation. Always coordinate with the surgical team and any other medications that affect bleeding.
