How does estrogen affect calcium levels in bones?
Estrogen has multiple other effects that relate to the skeleton. For example, enhanced intestinal calcium absorption can be beneficial to bones. Estrogen protects the bone from the resorptive effects of PTH. Estrogens may interact with mechanical forces to build bone.
How does smoking cause osteoporosis?
Specifically, recent evidence demonstrates tobacco smoking causes an imbalance in the mechanisms of bone turnover, leading to lower bone mass and bone mineral density (BMD) making bone vulnerable to osteoporosis [4–8] and fracture [4, 5, 7–11].
Does smoking affect cartilage?

What are the 3 calcium regulating hormones?
Three calcium-regulating hormones play an important role in producing healthy bone: 1) parathyroid hormone or PTH, which maintains the level of calcium and stimulates both resorption and formation of bone; 2) calcitriol, the hormone derived from vitamin D, which stimulates the intestines to absorb enough calcium and …
Can smoking weaken your bones?
Smoking affects the body’s ability to absorb calcium, leading to lower bone density and weaker bones. Nicotine slows the production of the bone-forming cells that are so crucial to healing.
