Osteoarthritis is a joint disease that mostly affects cartilage. Cartilage is the slippery tissue that covers the ends of bones in a joint. Healthy cartilage allows bones to glide over each other. It also helps absorb shock of movement.
Of the estimated 8.9 million Americans affected by osteoporosis, at least 80% are women. Experts believe women are more susceptible because their bones tend to be lighter and less dense and because women's bodies experience hormonal changes after menopause that accelerate the loss of bone mass.steoporosis, which means porous bones, is a condition that causes bones to gradually thin and weaken, leaving them susceptible to fractures. About 2 million fractures occur each year due to osteoporosis.
