Purpose: The purpose of this study was to examine Bone Marrow Density (BMD) of women suffering from general pain after childbirth. Methods: We studied 18 patients visiting $igcircigcirc$hospital from March 2007 to May 2010. The subjects were categorized in two groups, symptom group(n=12) and no symptom group(n=6). We measured BMD using Dual Energy X-ray Absorptiometry (DEXA) and studied the difference of BMD between two groups by Student T-test using SPSS for windows(version 13.0). Results: The general characteristics such as age, days of postpartum, primiparity, cesarean section, breast-feeding of two groups were not different statistically. BMD, T-score and Z-score of symptom group were statistically lower than no symptom group. Conclusion: The results suggest that women suffering from general pain after childbirth shows low BMD, T-score and Z-score. It seems to be due to the kidney deficiency after childbirth.
