Bone mass generally peaks around the age of 30-35, and then starts to slowly decline at around age 50 in women (60 in men) when you start to lose bone mass faster than your body can grow it back. This happens to all adults, however critical loss of bone mass (osteoporosis) is much more common in women.
Men in their fifties do not experience the rapid loss of bone mass that women do in the years following menopause. By age 65 or 70, however, men and women are losing bone mass at the same rate, and the absorption of calcium, an essential nutrient for bone health throughout life, decreases in both sexes.Excessive bone loss causes bone to become fragile and more likely to fracture.t is increasingly common for women to be diagnosed with osteoporosis or low bone mass using a BMD test, often at midlife when doctors begin to watch for signs of bone loss. In men, however, the diagnosis is often not made until a fracture occurs or a man complains of back pain and sees his doctor.
