What is Osteoporosis?
It is a metabolic bone condition characterized by low bone mass and reduced bone strength. Bones are the major reservoir of calcium in the body and are subjected to constant bone turnover. Like a house of bricks, bone cells are removed (by osteoclasts) then replaced by new bone (osteoblasts) all the time. In osteoporosis, more bone is removed than replaced by the body. As its microarchitecture is affected, bones becoming more brittle and prone to fractures.
Who gets it?
Men are also affected by osteoporosis, but this is far less common. Men’s bone health is controlled by both the oestrogen and testosterone hormones. Osteoporosis in men is mostly affected by lifestyle factors and medication.
• Sedentary lifestyle
• Low body weight
• Positive family history
Medication causing osteoporosis
• Long term steroids
• Chemotherapy medication
• Chronic renal failure
• Liver disease
• Rheumatoid arthritis
• Type 1 Diabetes Mellitus (DM)
Is osteoporosis dangerous?
Over the last 30 years in Singapore, the cases of hip fractures have increased 5 times in women aged 50 and above, and only less than double in men of the same age group.

Medication for osteoporosis
There are several types of medication to treat osteoporosis, ranging from weekly oral medication to daily or 6-monthly subcutaneous injections. Each type has its advantages and disadvantages but are designed to build stronger bones and prevent fractures and other complications.
Some medications include:
- Hormone replacement therapy (HRT)
- Selective oestrogen receptor modulators (SERMs)
- RANK ligand (RANKL) inhibitor
