Vitamin K deficiency: 9 symptoms and consequences

4. Blood in the urine

If blood clotting is disturbed due to a vitamin K deficiency, in severe cases even red blood cells can enter the urine of those affected. At the so-called hematuria urine may therefore turn slightly red under certain circumstances. The phenomenon also occurs in some kidney diseases such as kidney stones or kidney cancer.

5. Stomach bleeding with vomiting

The increased tendency to bleed due to a vitamin K deficiency can also be felt inside the body. In addition to the intestine, the stomach can also be affected by bleeding. More profuse stomach bleeding can also lead to bloody vomiting, a clear warning sign that should prompt you to see a doctor right away. Because in addition to a lack of vitamin K, ulcers, inflammation of the gastric mucosa or foreign bodies can also be triggered.

6. Increased risk of cardiovascular disease

Several animal and human studies have already shown that vitamin K is important for blood vessel health. As part of the Rotterdam Heart Study, the researchers found that test subjects who consumed many foods with a high vitamin K2 content over the ten-year observation period had significantly less deposits in the vessel walls and therefore were less likely to develop arteriosclerosis. compared to those low in vitamin K. With a good intake of vitamin K, the risk of coronary heart disease (CHD) also decreased and the participants’ overall cardiovascular health improved.

7. Pitch black stool

Due to the increased tendency to bleed and possible stomach bleeding with vitamin K deficiency, stool can also become discolored. While traces of bright red blood on the anus or stool indicate there is bleeding in the posterior sections of the intestine, hemorrhoids or anal fissures, for example, it also speaks of a dark to pitch-black discoloration tar feces called – due to the fact that bleeding already occurs in the stomach or even in the esophagus. Because the bright red pigment in the blood is in contact with stomach acid hematin chloride converted and discolored thereby from dark to black. If so, contact your doctor immediately unless you are sure the discoloration is due to excessive consumption of beets, blueberries or iron tablets.

8. Difficulty concentrating and tiredness

A vitamin K deficiency is not always evident through typical symptoms such as a tendency to bleed. Unfortunately, in case of vitamin K deficiency, widespread symptoms such as lack of concentration, constant fatigue or headache can also occur. In particular, mild deficiencies are difficult to identify with such general symptoms, as general malaise occurs with most vitamin and mineral deficiencies. Therefore, consult your doctor for clarification if you have recently been unusually tired and unable to concentrate.

9. Increased susceptibility to infections

Are you constantly sick or do you catch a cold more often than usual? In the beginning, there is a slight shortage of supply due to an increased susceptibility to infections. This rather nonspecific symptom also makes it difficult to directly infer a vitamin K deficiency. Additionally, increased susceptibility to infections is also a common sign of other nutritional deficiencies or diseases. If you are often sick or have a cold, you should definitely get a blood test from your family doctor.
