7 Lesser-known Ways Vitamin B12 Deficiency Can Be Harmful
Memory loss
You might be surprised to learn that a vitamin B12 deficiency can cause forgetfulness, confusion, and difficulty concentrating. Incorporating vitamin B12-rich foods such as eggs, fish, and dairy products can help increase levels.
Eye health
Optic nerve damage is another significant effect of a vitamin B12 deficiency. This eye disease can cause blurred, double, or even permanent vision loss.
Depression
You might also feel depressed due to a lack of vitamin B12. Low B12 levels are linked to mood disorders, making you feel depressed, sad, and anxious.
Muscle weakness
B12 produces red blood cells and nerve function. Hence, B12 deficiency can lead to coordination problems and may cause inflammation and pain in joints.
Digestive disorders
Lower B12 levels may cause gastrointestinal symptoms such as diarrhea and constipation or make you feel bloated.
Heart palpitations
If your body is vitamin B12 deficient, it will affect red blood cell production, and may also lead to heart palpitations, dizziness, and shortness of breath.
Pale skin
Pale or jaundiced skin is an observable sign due to anemia. When your body lacks sufficient B12 and can’t form healthy blood cells, this can result in oxygenated blood, which may cause pale skin.
