Key result
High-energy drink consumption and inadequate dietary intake over 6 months were associated with severe acquired vitamin K deficiency presenting as severe menorrhagia (INR 5.97).
Case Report (n=1)
Highlights the potential for severe menorrhagia due to acquired vitamin K deficiency associated with high-energy drink consumption and poor diet.
Prompts dietary inquiry in unexplained coagulopathy; case report leaves open energy drink contribution to vitamin K deficiency.
We report a rare case of acquired vitamin K deficiency presenting with severe menorrhagia and without any gynecological problem. Partial thromboplastin time (59.2 seconds) and prothrombin time (33.1 seconds, INR: 5.97) were considerably prolonged in laboratory evaluations. A complete coagulation factor assay test was performed for the patient: factor IX, 24%; factor II, 41%; factor VII, 3%; and factor X, 52%. She had been taking many high-energy drinks and she had inadequate dietary intake for the past 6 months. Given that she had vitamin K deficiency (VKD), a course of vitamin K therapy was started for her in the hospital. This case showed the potential for menorrhagia due to VKD with use of high-energy drinks and the value of a complete and detailed history in early diagnosis.

Zekavat et al. (2017) conducted a case report in Acquired vitamin K deficiency with severe menorrhagia (n=1). High-energy drinks and inadequate dietary intake was evaluated on Coagulation parameters and clinical presentation. High-energy drink consumption and inadequate dietary intake over 6 months were associated with severe acquired vitamin K deficiency presenting as severe menorrhagia (INR 5.97).
