Bone loss is best treated by correction of the underlying cause. [7] Patients should undergo evaluation of bone marrow density using a DEXA scan and started on Vitamin D and calcium supplementation. [7] If menstruation does not resume after 6 months with reasonable trial of non-pharmaceutical management, loss of bone mass becomes the main ...
At the age of 15 years, 5 months, her bone age was 11 or 12 years, and at the age of 17 years, 8 months, her bone age was 13.5 years. [9] Her bone mass was lower than expected for her age, and levels of osteocalcin and C-terminal telopeptide were both elevated, suggesting an increased rate of bone turnover. [ 9 ]

Delayed puberty means the lack of breast development by age 12.8 years for White girls, and by age 12.4 years for Black girls.

In response to the increased bone resorption, there is increased bone formation and a high-turnover state develops which leads to bone loss and perforation of the trabecular plates. [20] As osteoclasts break down bone, patients see a loss of bone mineral density (BMD). Low BMD renders bones more brittle and hence susceptible to fracture.
Polymenorrhea, also known as frequent periods, frequent menstruation, or frequent menstrual bleeding, is a menstrual disorder in which menstrual cycles are shorter than 21 days in length and hence where menstruation occurs more frequently than usual.
