Vitamin K deficiency is a medical condition that can occur when the body does not get enough vitamin K, a nutrient that is essential for blood clotting and bone health.

Causes

Vitamin K deficiency can be caused by a variety of factors. These include poor dietary intake, certain medical conditions that affect the absorption of vitamin K in the digestive system, and the use of certain medications, such as antibiotics, that can interfere with vitamin K absorption.

Symptoms

The symptoms of vitamin K deficiency can vary depending on the severity of the deficiency. Common symptoms include easy bruising, excessive bleeding, and blood in the urine or stool. In severe cases, vitamin K deficiency can lead to life-threatening bleeding disorders.

Diagnosis

Diagnosis of vitamin K deficiency is typically made through blood tests that measure the level of vitamin K in the body. Other tests may be used to assess the body's ability to clot blood, as this can be affected by vitamin K levels.

Treatment

Treatment for vitamin K deficiency typically involves increasing dietary intake of vitamin K and, in severe cases, may include vitamin K supplements or injections. It is important to treat vitamin K deficiency promptly to prevent serious complications.

Prevention

Prevention of vitamin K deficiency involves consuming a balanced diet that includes foods rich in vitamin K, such as green leafy vegetables, broccoli, and certain types of meat and dairy products. Individuals with medical conditions that affect vitamin K absorption may need to take vitamin K supplements to prevent deficiency.
