The silent syndrome
Chronically low iron stores can also be caused by untreated coeliac disease. I see more and more silent coeliac disease, where people don’t present with the typical bowel symptoms. Sometimes iron, and often vitamin B12 deficiency, are the only signs of what is later diagnosed on biopsy as coeliac disease. Once gluten is removed from the diet, iron levels return to normal. If you suspect that this could be the case, the first step is to see your GP for a blood test to screen for coeliac disease. For this initial test to be valid, it needs to be done before gluten is eliminated.
