HEALTH TIPS - OSTEOPOROSIS & CALCIUM REQUIREMENT |
|
Osteoporosis is a condition in which the bones become fragile and brittle, leading to a higher risk of fractures (breaks or cracks) than in normal bone. |
|
Osteoporosis occurs when bones lose minerals, such as calcium, more quickly than the body can replace them, leading to a loss of bone thickness (bone mass or density). As a result, bones become thinner and less dense, so that even a minor bump or accident can cause serious fractures. These are known as fragility or minimal trauma fractures. |
|
Any bone can be affected by osteoporosis, but the most common sites are bones in the hip, spine, wrist, ribs, pelvis and upper arm. Osteoporosis usually has no signs or symptoms until a fracture happens - this is why osteoporosis is often called the 'silent disease'. |
|
Fractures due to osteoporosis (osteoporotic fractures) can lead to changes in posture (eg developing a stoop or Dowager's hump in your back), muscle weakness, loss of height and bone deformity of the spine. Fractures can lead to chronic pain, disability, loss of independence and even premature death. |

To Prevent Osteoporosis : |

1. Exercise Regularly
2. Avoid Smoking or Eating Tobacco
3. Avoid Drinking Alcohol
4. Take a diet rich in Calcium and Vitamin D |

Fifteen minutes of sun each day is enough to make and store all the Vitamin D you need. However in old age, the ability of the skin to make Vitamin D decreases. Such persons will need to fulfill their daily requirement from diet or Vitamin D supplement. |

Exercises To Prevent Osteoporosis : |
What are the best exercises for strong bones? |
|
Exercises which mean your body has to carry its own weight (e.g. walking, but not
swimming), and which involve running, jumping or skipping, help new bone to
grow and prevent bone loss. Walking, jogging, dancing, tennis, volleyball, lifting
weights, and netball, are all good.
|
|
Tips for a good bone-health exercise program |
|
• to have an effect on bone, exercise needs to be REGULAR and FAIRLY
VIGOROUS. Doing a VARIETY of different exercises is best because it exercises
bone in different ways. SHORT, INTENSE BURSTS of exercise
(e.g. 15 minutes lifting weights or very brisk walking) is probably better for
bones than a leisurely one hour walk. |
|
• 2 short exercise sessions (20 minutes) separated by 8 hours is better for
bone, than one long session |
|
• Start slowly and progress gradually |
|
• Activities that promote muscle strength, balance and co-ordination, help to
prevent falls. Pilates, gentle yoga and Tai Chi are all good activities to help
prevent falls. |
|
Exercise for managing osteoporosis |
|
If you already have osteoporosis and have had fractures, it’s good to ask a
doctor or physiotherapist before starting an exercise program. |
|
• start with a basic strengthening program
• join a falls prevention class
• if you have had a fracture |
|
- avoid jarring, twisting or jumping movements
- avoid abrupt or sudden high impact movements
- avoid abdominal (stomach) curl ups
- avoid forward bending from the waist
- avoid heavy lifting |
