Why is bone health important?
Your bones are continuously changing — new bone is made and old bone is broken down. When you're young, your body makes new bone faster than it breaks down old bone and your bone mass increases. Most people reach their peak bone mass around age 30. After that, bone remodeling continues, but you lose slightly more than you gain. How likely you are to develop osteoporosis — a condition that causes bones to become weak and brittle — depends on how much bone mass you attain by the time you reach age 30 and how rapidly you lose it later. The higher your peak bone mass, the more bone you have "in the bank" and the less likely you are to develop osteoporosis as you age.
What affects bone health?
A number of factors can affect bone health — some modifiable and some not. For example:
-The amount of calcium in your diet.
-Physical activity level.
- Tobacco use and excessive alcohol consumption. ---Being a woman.
-Race, frame size and family history.
-Eating disorders and other conditions and procedures that affect bone health.
-Long-term use of corticosteroid medications
What can I do to keep my bones healthy?
You can take steps to prevent or slow bone loss. For example:
Include plenty of calcium in your diet.
Pay attention to vitamin D.
Include physical activity in your daily routine.
. Avoid substance abuse.
Consider bone-boosting medications.
Osteoporosis makes your bones weak and more likely to break. Anyone can develop osteoporosis, but it is common in older women. As many as half of all women and a quarter of men older than 50 will break a bone due to osteoporosis.
Risk factors include
Being small and thin
Having a family history of osteoporosis
Taking certain medicines
Being a white or Asian woman
Having osteopenia, which is low bone mass
