What are the Risk Factors for Vitamin B12 Deficiency?
Certain groups are at higher risk for B12 deficiency. These include the elderly, individuals with pernicious anemia, those with gastrointestinal disorders like celiac disease or Crohn's disease, and people who have undergone gastrointestinal surgery, which may affect absorption. Vegetarians and vegans are also at risk, as B12 is primarily found in animal products. Infants born to or breastfed by mothers who are vegetarians or vegans may also be at risk.
