Osteoporosis is a disease with a major sign of reduced bone mass density. As a result, bone fragility and fracture risk will increase. Often this osteoporosis is identified with bone loss or bone disease. As we get older, our bone mass will decrease. Actually the condition is natural. Bone mass in women is relatively reduced faster than men. This is due to menopause, where the function of ovaries decreases dramatically which affects the production deficiency of estrogen and progesterone.
When the hormone estrogen drops because of advanced age, there is a decrease in the activity of osteoblast cells that contribute to the formation of new bone. The cause of osteoporosis is generally divided into two categories, namely the cause of primary and secondary osteoporosis. The cause of primary osteoporosis is due to menopause and old age. While some secondary causes include: the use of corticosteroid drugs, metabolic disorders, poor nutrition, poor absorption, bone marrow disease, impaired renal function, liver disease, chronic lung disease, spinal cord injuries, rheumatism, and organ transplants.
Osteoporosis usually occurs gradually. Starting from a normal bone condition, then bone loss begins until it becomes a severe osteoporosis.
