Description
Eva Greibe and colleagues report a 2026 pilot study on blood levels of intrinsic factor, the stomach protein that lets the body absorb vitamin B12. Tiny amounts leak into the blood, and the team asked whether the level reflects the state of the stomach lining. They tested three groups: patients before and after weight-loss surgery, patients with portal hypertension, and patients checked for suspected pernicious anemia.
After weight-loss surgery, blood levels fell within two months, and over a third of patients dropped below the normal band, matching the known fall in B12 uptake. The other groups gave mixed pictures, with a few strikingly high values in liver-pressure patients and low values in most antibody-positive anemia cases. Larger, longer studies must judge the test's worth.
