In about one-quarter of women, this deterioration eventually results in the porous, brittle bones characteristic of osteoporosis...
...disrupted. The upset was caused either by a failure to ovulate (or produce an egg) or by a shortened "luteal phase," a critical stage of the menstrual cycle during which the hormone progesterone is produced. More important the researchers found that these disturbances were directly related to dramatic bone loss: the 20% who missed ovulation at least once, for example, suffered as much as a 4% reduction in bone density in one year...
...might menstrual problems hurt bones? Lead researcher Jerilynn Prior believes that reduced levels of the hormone progesterone -- which was suppressed in women with cycle disruptions -- may explain the damage. Some studies have indicated that this hormone helps with bone formation. Prior is not certain what causes the menstrual disturbances. The most likely candidate, she says, is stress...
