What is a T-score and what number means osteoporosis?

A T-score compares your bone density to that of a healthy young adult. A score of -1.0 or above is normal, between -1.0 and -2.5 is osteopenia (low bone mass), and -2.5 or below indicates osteoporosis. If you also have a fragility fracture, it is called severe or established osteoporosis. The T-score comes from a DEXA scan and is one part of assessing your risk — your doctor also considers your age, fracture history, and other factors using fracture-risk calculators.

Is osteoporosis reversible?

Osteoporosis can usually be managed and fracture risk reduced, even if bone density is not fully 'reversed'. Bone-strengthening medications, adequate calcium and vitamin D, weight-bearing and muscle-strengthening exercise, stopping smoking, limiting alcohol, and reducing fall risks all help protect your bones. Some treatments can increase bone density over time. The goal of care is to prevent fractures, so ask your doctor about the combination of medication and lifestyle steps best suited to your risk level.

What are the main risk factors for osteoporosis?

Key risk factors include increasing age, being female (especially after menopause), a family history of osteoporosis or hip fracture, early menopause, low body weight, smoking, excess alcohol, and long-term use of steroid medications. Some medical conditions and treatments also weaken bones. Because many people have no symptoms until a fracture, knowing your risk factors helps decide whether you need a DEXA scan and preventive treatment, which is a central part of an osteoporosis appointment.

Should I take calcium and vitamin D supplements for my bones?

Adequate calcium and vitamin D are important for bone health, but the best source of calcium is usually diet, and supplements are advised selectively rather than for everyone. Vitamin D supplements are more commonly recommended, particularly if your level is low or your sun exposure is limited. Because the right approach depends on your blood levels, diet, and overall risk, ask your doctor what you specifically need rather than starting high-dose supplements on your own.

Preparing for Appointments with Osteoporosis

Quick answer: Bring your DEXA (bone density) scan result if you have one, a list of any previous fractures (especially from minor falls), and your full medication and supplement list including vitamin D and calcium. Osteoporosis means bones are more fragile and break more easily — it is silent until a fracture, so the appointment is about assessing risk and protecting your bones before that happens.

Osteoporosis thins and weakens bones so they break more easily, often with little or no warning until a fracture occurs. Because it is silent, the appointment is really about risk: your bone density (DEXA) score, your fracture history, and the factors — including vitamin D, calcium, and certain medicines — that influence bone strength.

What to Bring and Track

Your DEXA result: the T-score, if you have had a scan
Fracture history: any broken bones, especially from a standing-height fall or minor knock
Height: loss of height can suggest spinal fractures
Risk factors: family history, early menopause, smoking, alcohol, long-term steroid use
Medications and supplements: including calcium and vitamin D. A appointment notebook keeps it together.

Understanding Your Bone Density (T-score)

T-score	Category
-1.0 and above	Normal bone density
-1.0 to -2.5	Osteopenia (low bone mass)
-2.5 and below	Osteoporosis
-2.5 or below + a fracture	Severe (established) osteoporosis

The T-score compares your bone density to a healthy young adult. It is one part of the picture — your doctor also uses fracture-risk tools that combine age, history, and other factors. See our DEXA scan guide for a full explanation.
