10 Vitamin B12 Deficiency Symptoms
Symptom #6: Skin Paleness or Jaundice
People that have B12 deficiency are usually pale or have a slight yellow tinge to their skin and the white part of their eyes. This condition is called jaundice and happens when a lack of B12 brings about problems in your body’s production of red blood cells. Vitamin B12 plays an essential role in the production of red blood cells.
There is a type of anemia known as megaloblastic anemia that causes the red blood cells located in your bone marrow to be large and fragile such that they cannot pass out of your bone marrow and into circulation. This denies blood the supply of these red blood cells. The shortage causes the skin to appear pale in color. Because of their fragility, many of these cells break down and cause excess bilirubin and yellowing of the skin and the white parts of the eyes.
