Vegetarian Diet and B12 Deficiency
Vitamin B12 Deficiency Seen in All Types of Vegetarians
Your Body and Vitamin B12
Vitamin B12 helps maintain healthy nerve and red blood cells and is also needed to make DNA, which is why it's especially important that pregnant and nursing women consume enough.
Vitamin B12 deficiency leads to anemia. Symptoms of vitamin B12 deficiency, which usually come on gradually, include fatigue, weakness, nausea, and constipation. Long-term and severe vitamin B12 deficiency can lead to nerve changes such as numbness, tingling in the hands and feet, balance and memory problems, and depression.
A blood test is the best way to test for vitamin B12 deficiency, and Herrmann recommends that all vegetarians get tested every year.
