Vitamin B12 deficiency impairs the production of healthy red blood cells and the function of nerves. Symptoms range from fatigue and pallor to numbness, tingling, balance problems, memory changes, and a sore tongue. It is most common in older adults, vegans, those on long-term acid suppression or metformin, and patients with autoimmune pernicious anemia or prior gastric surgery. Diagnosis combines a serum B12, sometimes with methylmalonic acid. Treatment is oral high-dose B12 for mild cases and intramuscular cyanocobalamin or hydroxocobalamin when absorption is impaired.
