Question

how to diagnose B12 defficiancy ​

Answer 1

B12 can lead to anemia, which means your body does not have enough red blood cells to do the job. This can make you feel weak and tired. Vitamin B12 deficiency can cause damage to your nerves and can affect memory and thinking.

So if u feel weak or tired & cant remember things more often u might have vitamin B12 deficiency.
