Vitamin B12 Deficiency
A lack of vitamin B12 that can cause anemia, nerve damage, and cognitive problems if untreated.
Overview
Vitamin B12 deficiency occurs when the body doesn't have enough of this essential nutrient, which is needed for red blood cell production, nerve function, and DNA synthesis. It is common in older adults, vegans and vegetarians, and people with gastrointestinal conditions that impair absorption (like celiac disease or pernicious anemia). If untreated, it can cause irreversible nerve damage and cognitive impairment. B12 deficiency is easily treated with supplements or injections.
