The disease caused by lack of all vitamins, including vitamin K, is called malnutrition. Malnutrition can have serious consequences on the body, including impaired growth and development, weakened immune system, and reduced cognitive function. Vitamin K deficiency specifically can lead to bleeding disorders, as it is required for proper blood clotting. Severe vitamin K deficiency can result in hemorrhaging or excessive bleeding, which can be life-threatening if not treated promptly.
