Case: bruises for no reason<\/h2>\n

Anna, 43 years old, went to the doctor with complaints of frequent bruising on the legs and arms<\/strong>, which appear without strokes. She was also worried about bleeding gums<\/strong> while brushing teeth. Complete blood count \u2014 no changes. Clotting time is prolonged. The doctor prescribed blood test for vitamin K levels<\/strong>.<\/p>\n

What did the analysis show?<\/h2>\n

Vitamin K1 (phylloquinone) level \u2014 0.08 ng\/ml<\/strong>, that below the lower limit of normal<\/strong>. Additionally, it turned out that Anna does not eat green vegetables and has been taking a tetracycline antibiotic for several months after chronic sinusitis.<\/p>\n

What does this mean?<\/h2>\n

Vitamin K is key for synthesis of blood clotting factors<\/strong>. Its deficiency may remain unnoticed for years<\/strong>, but with a combination of diet, medication, and gut condition leads to bleeding and the threat of hemorrhage<\/strong>.<\/p>\n

What do you need to know about vitamin K?<\/h2>\n
