Osteoporosis is a condition where bones become weak, porous, and brittle, making them much more likely to break from a fall or even minor stress. It is often called a “silent disease” because it typically has no symptoms until a fracture occurs. The fall in estrogen levels at menopause is the most common cause of osteoporosis, triggering a period of accelerated bone loss; some may lose up to 20% of their bone mass in the 5-7 years following menopause. This is why approximately one in two postmenopausal women will experience an osteoporosis-related fracture in their lifetime, most commonly of the hip, spine, or wrist.
