Your body constantly tears down and rebuilds bone, storing calcium. From birth until age 30, your body builds bone faster than it tears it down. This is when bones are the strongest. After that time, you begin to gradually lose bone. When you go through menopause and your ovaries decrease the amount of estrogen they produce, you will experience bone loss because estrogen is also important in maintaining bone.
Poor nutrition can also contribute to bone loss.
Treatments can help stop bone loss. Some treatments can even help you regain some bone. However, the key is to prevent bone loss. Bones become weak and may fracture easily. Fractures can be very painful.
