Weak Bone is a disease that weakens bones and can cause them to break more easily. It is a disorder of decreased mineralization, which results in bone breaking down faster than it can re-form. It is a condition that occurs in adults. In children, inadequate concentrations of vitamin D may cause rickets.
It is a disease that weakens bones, and if you have it, you are at a greater risk for sudden and unexpected bone fractures. Osteoporosis means that you have less bone mass and strength. The disease often develops without any symptoms or pain, and it is usually not discovered until the weakened bones cause painful fractures. Most of these are fractures of the hip, wrist and spine.
Your bones are alive and constantly growing — not static, like you see them drawn in books. Bones continually change throughout your life, with some bone cells dissolving and new bone cells growing back in a process called remodeling. With this lifelong turnover of bone cells, you replace most of your skeleton every 10 years.
Bone density is greatest in your early 20s. But as you age, you can lose bone mass from a variety of factors. Osteoporosis or its early warning sign, osteopenia, signals an imbalance in the remodeling process: Too much bone is broken down, and too little new bone is built back up. Brittle bones result, prone to fracture.
You probably know that you need calcium to build strong bones, but a low-calcium diet isn’t the only culprit. There are lesser-known causes of osteoporosis. The experts now believe that a combination of causes is often to blame for bone loss.
Your bones are made of living, growing tissue. The inside of healthy bone looks like a sponge. This area is called trabecular bone. An outer shell of dense bone wraps around the spongy bone. This hard shell is called cortical bone.
When osteoporosis occurs, the “holes” in the “sponge” grow larger and more numerous, which weakens the inside of the bone. Bones support the body and protect vital organs. Bones also store calcium and other minerals. When the body needs calcium, it breaks down and rebuilds bone. This process, called bone remodeling, supplies the body with needed calcium while keeping the bones strong.
Up until about age 30, you normally build more bone than you lose. After age 35, bone breakdown occurs faster than bone buildup, which causes a gradual loss of bone mass. If you have osteoporosis, you lose bone mass at a greater rate. After menopause, the rate of Weak Bone / breakdown occurs even more quickly.
Most new bone is added during childhood and teenage years. As a result, bones become larger, heavier, and stronger (denser). Bone formation continues until the peak bone mass (maximum solidness and strength) is reached. Peak bone mass (or bone density) is reached around age 30. After age 30, bone resorption slowly begins to exceed new bone formation. This leads to bone loss. Bone loss in women occurs fastest in the first few years after menopause, but bone loss continues into old age.
Factors that can contribute to bone loss include having a diet low in calcium, not exercising, smoking, and taking certain medications such as corticosteroids.
Corticosteroids are medications prescribed for a wide range of diseases, including arthritis, asthma, inflammatory bowel disease, lupus, and other diseases. Corticosteroids may cause osteoporosis when used chronically.
