Are eating disorders linked to lower basophil counts?
Yes—across a review of 38 studies, basophil counts were lower in people with anorexia or bulimia than in healthy people.
The review examined blood cell counts in people with eating disorders. Of the included studies, 27 compared people with anorexia with healthy people. Eight made that comparison for bulimia. Seven followed people with anorexia during recovery. Some studies covered more than one type of comparison.
For our Basophils % community, one distinction matters: counts are not percentages. This review measured cell counts, not their share of all white blood cells. Its basophil finding is therefore about Basophils (Absolute). It does not establish that the percentage was lower, too.
In anorexia, WBC (White Blood Cells) and several cell types were lower. In bulimia, most counts were unchanged, but basophil counts were lower. The source summary does not say how large that difference was.
Recovery findings added another piece. Total white blood cell counts did not change after shorter-term gains in Weight. They rose later, when BMI (Body Mass Index), a measure relating body size to height, approached 18.5 kg/m². This was not a finding about basophil recovery specifically. The authors suggested that too little nourishment likely explains the lower counts in anorexia.
For members tracking bloodwork, this supports looking beyond one percentage. Comparing percentages, absolute counts, and total counts keeps different measures separate. Test dates and recovery context can also make community comparisons more meaningful. These group findings cannot explain one person's result by themselves.
What have you noticed when comparing your Basophils % with your absolute counts across blood tests?
