The paper presents the data on the condition of the bone tissue in the healthy women of the reproductive age as compared with pregnant healthy women and pregnant women with extragenital disorders. The bone tissue density was measured by ultrasound bone densitometry.
Results of the research have shown that during the pregnancy course the bone tissue density decreases in the pregnant healthy women and the parameters of the bone mineral density are much more lower in comparison with nonpregnant women. Secondary osteoporosis takes place in pregnant women with extragenital disorders that contribute significantly to accelerated bone loss.
