Lesson on Vitamin B12 Deficiency Causes, including dietary intake issues, medication use, gastrointestinal disease (ex. crohn’s disease, celiac disease), GI infections, pancreatic disease and autoimmune conditions (ex. pernicious anemia). Vitamin B12 (cobalamin) is essential in our diet as we are not able to synthesize it ourselves, and it is necessary for healthy red blood cell production, DNA synthesis and central nervous system functioning. Vitamin b12 deficiency can be due to a variety of causes within 2 major categories: reduced dietary intake and compromised absorption. Compromised absorption entails a wide variety of causes including certain medications, and issues within the gastrointestinal tract.

In this lesson, we discuss a detailed overview of causes of Vitamin b12 deficiency, including discussing pernicious anemia, crohn’s disease, celiac disease and We also discuss the physiology of normal B12 metabolism and absorption and discuss where in this physiological pathway many disease states interfere with B12 absorption.
