Five things quietly weakening your bones

Around 6.2 million Australians over 50 live with weakened bones. Many of the everyday habits behind it are surprisingly common.

1. Too much sitting

Bone needs load. Long periods without weight-bearing movement send a signal that less bone is required.

2. Low protein or calcium intake

Bone is a living tissue — it needs raw materials daily to remodel. Chronic under-intake accelerates loss.

3. Vitamin D deficiency

Without vitamin D, calcium absorption drops dramatically, regardless of how much is in your diet.

4. Smoking and heavy alcohol use

Both interfere directly with bone-building cells and increase fracture risk over time.

5. Undiagnosed hormonal shifts

Perimenopause, thyroid changes and low testosterone all affect bone. Regular check-ups catch them early.
