3.Causes
Estrogen is a hormone that helps you build and protect bone. When estrogen levels are low you lose bone. You also lose bone during and after menopause when your ovaries stop making estrogen. Your risk of getting osteoporosis goes up if you didn’t build enough bone as a child from an eating disorder, lack of vitamin D or calcium, lack of exercise, or another health problem.
4.Risk Factors
Osteoporosis can happen at any age, but it’s most common in adults over 50. Women are four times more likely to get it than men. Your chance of bone loss goes up if you’re Asian or white, have a small body frame, and if you have a family member with osteoporosis — especially if that family member fractured a bone.
