3- You get pins and needles often
Everyone gets pins and needles from time to time, but when it becomes a near-constant sensation, it is a common sign of nerve damage.
Nerve damage is one of the most serious consequences of B12 deficiency.
This is because B12 helps your body to produce a substance called myelin, which is a fatty insulation to protect your nerves.
4 – You feel off-balance
Because of the damage B12 deficiency can do to your nervous system, it can affect your balance and coordination, making you more likely to fall over.
5 – You suffer poor oral hygiene
Low levels of vitamin B12 can lead you to suffer frequent mouth ulcers and bleeding gums.
Bleeding gums are a symptom of serious gum diseases, so before jumping to a B12 deficiency diagnosis, go and see your dentist to rule out any dental causes.
You can also develop glossitis, a condition where your tongue becomes inflamed.
Glossitis can make your tongue painful, and even change the way you speak.
