Nosebleeds

Nosebleeds, also called epistaxis, have a variety of causes and occur more often in children under the age of 16. In most cases, nosebleeds are caused by minor trauma and stop bleeding within minutes, especially if ice is applied or the bridge of the nose is pinched. 

Vitamin deficiency nosebleeds in children and adults are more difficult to stop.

The blood vessels of the nose are relatively fragile and easily rupture with nasal trauma, either from a physical blow or from forcefully blowing the nose. They can also be a result of mucosal dryness and inflammation, aggressive nose picking that damages the mucosal linings or epithelium, a benign growth at the back of the nose or a blood-clotting disorder. 

A lack of certain vitamins, especially K and C, can contribute to the mechanisms of nosebleeds.

Vitamin C is necessary for the development of normal collagen, which is the main component in connective tissue. Collagen resides within skin and blood vessels.

A deficiency of vitamin C weakens blood vessels, which can lead to a condition called fragile capillaries. The fragile vessels and capillaries of the nose are especially reliant on healthy collagen to prevent rupture and leakage.

Severe vitamin C deficiency, known as scurvy, commonly leads to easily provoked bleeding from the nose and gums, as well as bruising of the skin and muscles.
