Symptoms I experienced during 2 years of B12 deficiency
- Periods of extreme dizziness (I could not stand up)
- Brain fog
- Fatigue
- Visual auras, scotomas (blind spots in your vision)
- Migraines (a migraine is not “just a headache”)
- Warts
- Hair loss
- Gall bladder inflammation (specific cause not determined but B12 deficiency is a known factor)
- Non A/Non B/Non C hepatitis (B12 deficiency can be either a cause or an effect of hepatitis)
My doctor has me taking 1,000 mcg of vitamin B12, every day and the above issues cleared up.
You are at risk of B12 deficiency if you are vegan, vegetarian (even if you are an accidental vegetarian who still eats meat occasionally but rarely), are an older adult, or have certain diseases that reduce B12 absorption.
