Cyclic Progesterone Therapy

Progesterone is one of two important hormones for women (estrogen is the one we usually hear about). Menstrual cycle hormone levels can be disturbed, even during regular cycles. The most common disturbance is of ovulation causing progesterone levels to become too low or absent.

The ABCs of Osteoporosis Prevention for Teenage Women

The teen years are a time of major change occurring before and after the first menstrual period.

Building and maintaining our bones is not just about getting enough calcium—it is a "whole meal deal." Following these ABC's will help you prevent later fractures and osteoporosis.

Bone loss is more rapid from the start of irregular flow until a year after the final period compared to the first years of menopause.

Below are the many practical things you can do (with the help of your health care provider) to prevent or treat osteoporosis, the problem of weak or fragile bones. Bone health is influenced by how we live our lives
