[Osteoporosis in pregnancy and lactation]

In the second half of the twentieth century different patterns of bone mass changes in young women were described in association with pregnancy and lactation. Pregnancy-associated osteoporosis may present as predominant bone loss from the hip; there is a second form with vertebral involvement; and it may present with fractures at atypical sites such as the sacrum. Long-term lactation is also associated with increased bone loss. In our work we describe a clinical case of a 34-year old lactating woman, presenting at the fourth month after unremarkable childbearing with vertebral fractures and overt osteoporosis. We described the diagnostic procedures and therapeutic interventions. A literature review is also presented. In conclusion, osteoporosis of pregnancy and lactation should not stay out of the clinician's focus and requires a multi-disciplinary approach.
