6. Pins-and-needles sensations
This tingly sensation that may appear in the hands and feet is called paresthesia. Lots of patients with diagnosed B12 deficiency noticed this symptom.
Paresthesia is a very common symptom in people with diabetes who are prescribed metformin to lower blood sugar levels. This is because metformin can reduce B12 absorption in the body. So, if you regularly take this drug, you should get checked your vitamin B12 levels regularly.
7. Twitching eye
The first thing you probably think about when your eyes start to twitch is: “Well, there’s another nervous tic.” In some cases, such an unpleasant symptom can indeed indicate that there is too much stress in your life.
However, a twitchy eye can also be a sign of a vitamin B12 deficiency. The fact is that there are a lot of nerves around the eyeballs that react to a lack of this vitamin. You may feel both a twitching of the eyelid and a squeezing pain in the eyes.
