Compression Fracture in Postpartum Osteoporosis [PDF]

Journal of Bone Metabolism, 2014
Dear Editor, I read with interest your article titled, "Compression fracture in postpartum osteoporosis".[1] I am a lactation consultant and I experienced a similar medical situation. I would like your readers to know that weaning is not necessarily indicated in the case of postpartum osteoporosis. Weaning was advised, but I was adamant to find a
