Vitamin K Deficiency Causes Blood Non-Clotting

Non-clotting of blood is primarily linked to a deficiency in a specific vitamin essential for the coagulation process.

Role of Vitamin K in Blood Coagulation

  • Vitamin K plays a critical role in synthesizing several blood clotting factors (specifically factors II, VII, IX, and X) in the liver.
  • These factors are crucial for the coagulation cascade, the process that leads to blood clot formation.
  • A deficiency in Vitamin K impairs the liver's ability to produce these factors, leading to insufficient clotting ability.
  • This condition can result in prolonged bleeding (hemorrhage) even from minor injuries.

Other Vitamins and Blood Clotting

  • Vitamin D: Primarily involved in calcium absorption and bone health. It does not directly affect blood clotting.
  • Vitamin A: Important for vision, immune function, and skin health. It does not play a direct role in blood clotting.
  • Vitamin B (complex): Involved in various metabolic processes, energy production, and nerve function. Specific B vitamins like B12 and folate are related to red blood cell formation but not directly to the clotting mechanism itself.

Therefore, the deficiency directly causing non-clotting of blood is Vitamin K deficiency.
