Background:

Pregnancy-associated osteoporosis (PAO) is a rare condition characterized by vertebral fractures during late pregnancy or postpartum.
The exact clinical features, metabolic abnormalities, and pathological mechanisms of PAO remain incompletely understood.
Existing literature suggests a potential link between physiological changes during pregnancy and the development of bone fragility.

Purpose of the Study:

To review current data on osteoporosis in pregnant women.
To discuss the relationship between pregnancy, bone mass, and calcium homeostasis.
To explore the role of systemic skeletal hormones and local factors in the pathophysiology of PAO.

Main Methods:

Literature review of existing studies on osteoporosis and pregnancy.
Analysis of data concerning calcium homeostasis and hormonal changes during gestation.
Discussion of local factors potentially influencing bone metabolism during pregnancy.

Main Results:

PAO is a rare but recognized complication of pregnancy.
Pregnancy significantly impacts calcium homeostasis and bone turnover.
Systemic and local factors during pregnancy may contribute to bone loss and fracture risk.

Conclusions:

Understanding the interplay between pregnancy physiology and bone metabolism is crucial for explaining PAO.
Further research is needed to fully elucidate the pathological mechanisms underlying this disorder.
This review provides a framework for understanding the pathophysiology of pregnancy-associated osteoporosis.
