This complex process means that conditions affecting the stomach or intestines can significantly impair B12 absorption, including pernicious anaemia, atrophic gastritis, previous gastric surgery, coeliac disease, Crohn's disease, and long-term use of certain medications (such as metformin, proton pump inhibitors, and H2 antagonists)
Where serum B12 results are borderline or do not fit the clinical picture, further tests such as active B12 (holotranscobalamin), methylmalonic acid, or homocysteine may be helpful
