Vitamin K is a fat-soluble vitamin stored in your liver, as well as in the fat cells of your body. Asparagus, romaine lettuce, kale, spinach, broccoli, cabbage and beef liver are abundant sources of this vitamin, according to the University of Maryland Medical Center. Vitamin K is necessary for blood clotting and bone health. Several symptoms may indicate a deficiency of this vitamin.
Excessive Bleeding
Excessive bleeding and prolonged clotting time are common symptoms of vitamin K deficiency, according to the Linus Pauling Institute at Oregon State University. Cuts, scrapes and surgical wounds may bleed for prolonged periods of time. Bleeding from the gums and frequent nosebleeds may also indicate vitamin K deficiency. This condition may also cause heavy menstrual bleeding.
Bone Fractures
Vitamin K helps your body use calcium to manufacture healthy bone cells, according to the University of Maryland Medical Center. Deficiency of vitamin K may therefore lead to osteoporosis, a condition that reduces the density of bone mass. This may cause frequent bone fractures and poor fracture healing.
Bruising
Increased bruising may indicate a deficiency of vitamin K, according to the Linus Pauling Institute at Oregon State University. Bruising occurs when blunt impact causes the capillaries of your skin to burst, causing blood to pool beneath the surface of your skin. If you have a vitamin K deficiency, even miner bumps may cause pronounced bruising. Bruises may also take longer to fade.
Blood in Urine and Stool
A vitamin K deficiency may cause bleeding of your liver, kidneys, intestines and urinary tract. You may notice blood in your urine or stools, according to the Linus Pauling Institute at Oregon State University.
