Abstract
Background and Objectives
Vitamin K-dependent clotting factor deficiency (VKCFD) is usually an acquired problem due to liver disease, malabsorption, and overdose of warfarin.  In the present paper the significance and role of vitamin K-dependent coagulation factors in menorrhagia were evaluated.
 
Case
We present a rare case of 43 year woman with acquired vitamin K deficiency and severe menorrhagia without any gynecological problem. The level of all Vitamin-K dependent coagulation factors, Fctor II, Factor VII, Factor IX, and Factor X decreased. Furthermore, even after multiple administration of Vitamin K  and its oral consumption, still the level of coagulation factors and menorrhagia did not ameliorate.
 
Conclusions 
Acquired VKCFD is one of the rare situations that can be life-threatening.
