“Patients who took PPI medications for more than two years had a 65 percent increase in their risk of B12 deficiency,” said Douglas A. Corley, a gastroenterologist and research scientist with the Kaiser Permanente Division of Research in a news release.
The risk also increases with higher doses of the drugs compared with lower doses.
There’s an easy fix though, according to Corley, who says a relatively simple blood test can determine whether it’s happening. If so, the issue can be resolved easily by taking vitamin supplements, he says.
Vitamin B12 deficiency left untreated can have dire consequences including dementia, nerve damage, and anemia.
