A lesser-known but significant symptom of vitamin B12 deficiency is jaundice, or icteris. This manifests as a yellow or green discoloration of the skin and whites of the eyes. This symptom is caused by elevated levels of bilirubin, a breakdown product of red blood cells. When the production of healthy red blood cells is disrupted due to a B12 deficiency, bilirubin accumulates in the blood, giving the skin and eyes a yellowish tint. Typically, the skin appears pale with a yellowish hue.

A severe vitamin B12 deficiency can also affect vision.
This deficiency can damage the optic nerve, resulting in blurred vision. People may think they need glasses when the problem actually lies in a vitamin B12 deficiency. Before changing glasses, it is recommended to have vitamin B12 levels checked. Appropriate supplementation can help restore normal vision if a B12 deficiency is the underlying cause of the problem.
