B. Smoking contributes to hypercoagulability and vascular damage, both of which elevate the risk of clot formation in veins.
C. A history of stomach ulcers is not directly associated with an increased risk of blood clots; rather, it pertains more to gastrointestinal health.
D. Overhydration generally does not increase the risk of blood clots; rather, maintaining adequate hydration is important for circulation.
