Vitamin B12 deficiency: Symptoms include disturbed vision – ‘See a GP’


Vitamin B12 powers your body in important ways, ranging from supporting the nervous system to helping with the production of red blood cells. The lack of this vitamin can therefore prove insidious. However, your vision could break the news of a vitamin B12 deficiency.

A medical institute Medanta explains that disturbed of blurred vision appear once the lack of B12 targets your optic nerve.

Medanta shares: “This happens when the deficiency causes damage to the optic nerve that leads to your eyes.

“The nervous signal that travels from the eye to the brain is disturbed due to this damage, leading to impaired vision.

“This condition is called optic neuropathy and treatment involving B12 supplements usually reverses the impairment.”

As these are all animal-derived, vegan and plant-based diet followers might often struggle to reach the target for B12. But they can be aided by supplements, for example.
