Low vitamin B12: Vitamin B12 deficiency is a low blood level of vitamin b12. It can cause permanent damage to nerves if left untreated long enough. Vitamin B12 was discovered through investigation of pernicious anemia, which is an autoimmune disease that leads to inadequate intestinal absorption of B12 from foods. Symptoms may include anemia and paresthesias (from nerve damage).

Agree with Dr. K: B12 deficiency can be treated with oral or sublingual B12 tablets or B12 injections.
