Metabolic & Bone Health

This section covers symptoms related to bone and mineral metabolism rather than problems affecting only one joint or region. These conditions often require blood tests and bone-density assessment to identify the underlying cause.

English தமிழ் हिन्दी

Fragility Fracture

What you'll notice or feel

A fracture occurring after a low-energy event such as a fall from standing height, a minor bump or sometimes even a simple movement such as coughing or bending.
Pain, swelling or inability to use the affected area following the injury.
Spinal fragility fractures may sometimes cause gradual back pain or height loss without a clearly remembered injury.

Common causes

Reduced bone density and strength (osteoporosis), commonly associated with ageing, menopause or long-term steroid use.
Poor bone mineralisation, often related to vitamin D deficiency (osteomalacia).
An overactive parathyroid gland affecting calcium and bone metabolism.
Other endocrine, kidney or nutritional conditions affecting bone strength.

What it could be

Osteoporosis — reduced bone strength that increases the risk of fractures following relatively minor forces.
Osteomalacia — inadequate bone mineralisation, often associated with vitamin D deficiency.
Primary hyperparathyroidism, which can contribute to bone loss and sometimes kidney stones.
Rarely, a local bone lesion weakening the bone at the fracture site.

What you can do while arranging assessment

Have the acute fracture assessed and treated first.
Reduce falls risk at home by keeping walkways clear, improving lighting and securing loose rugs.
Avoid starting high-dose calcium or vitamin D supplements without medical advice, as treatment should depend on the results of appropriate investigations.

When to see a doctor urgently

Any suspected new fracture.
Severe pain, inability to bear weight or visible deformity.

When to see a doctor

You have previously sustained a fragility fracture but have not had a formal bone-health assessment.
You have risk factors for weak bones such as long-term steroid treatment, early menopause, low body weight or a strong family history.

Diffuse Bone or Joint Pain

What you'll notice or feel

Aching affecting several bones or joints rather than one clearly localised area.
Pain that may feel deep or bone-related rather than sharp or confined to a single joint.
Pain that may worsen with weight-bearing or direct pressure over the bone.
Symptoms developing gradually without a specific injury.

Common causes

Vitamin D deficiency affecting bone mineralisation.
Significant osteoporosis-related bone changes.
Overactivity of the parathyroid gland.
Less commonly, inflammatory, kidney or bone-marrow conditions.

What it could be

Osteomalacia, often associated with vitamin D deficiency, producing diffuse bone discomfort.
Discomfort related to significant osteoporosis, sometimes associated with unrecognised small spinal fractures.
An inflammatory condition affecting multiple joints.
Rarely, a bone-marrow or malignancy-related condition.

What you can do while arranging assessment

Note which areas are painful and whether the discomfort is constant or intermittent.
Maintain sensible sun exposure and a balanced diet while arranging assessment.
Avoid starting strenuous new exercise programmes until the cause is understood, particularly if osteoporosis is possible.

When to see a doctor urgently

Pain associated with unexplained weight loss, fever or feeling generally unwell.
Severe or worsening pain, particularly at night or at rest.
Significant pain following even a relatively minor fall.

When to see a doctor

Diffuse bone or joint aching lasting more than a few weeks without an obvious explanation.
Pain occurring alongside weakness, fatigue or height loss.
Known risk factors such as limited sun exposure, restricted diet, kidney disease or medications affecting bone health.

Height Loss or Increasing Kyphosis

What you'll notice or feel

A gradual reduction in height over months or years.
Increasing rounding or stooping of the upper back.
Clothes fitting differently, particularly around the collar or waist.
Associated back discomfort in some people, although pain may be absent.

Common causes

Compression of one or more spinal bones due to osteoporosis.
Age-related changes in spinal discs and alignment.
Long-term postural changes with reduced core and back-muscle strength.
Less commonly, an underlying spinal or metabolic bone condition.

What it could be

Osteoporotic vertebral compression fractures.
Age- and posture-related spinal changes without significant loss of bone density.
Degenerative disc-related height loss.
Rarely, a bone lesion or other spinal pathology, particularly if change is rapid or painful.

What you can do while arranging assessment

Compare current height with previous documented measurements if available.
Gentle posture and core-strengthening exercises may be reasonable if comfortable.
Avoid forceful spinal bending or heavy lifting if a compression fracture is suspected.

When to see a doctor urgently

Sudden or rapid loss of height.
New or severe back pain occurring with height loss.
Numbness, weakness or bladder/bowel changes associated with back symptoms.

When to see a doctor

Noticeable height loss developing over time.
Increasing stoop or rounding of the upper back.
Known osteoporosis risk factors without recent bone-health assessment.

Proximal Muscle Weakness

What you'll notice or feel

Difficulty getting up from a low chair or from the floor without using your hands.
Difficulty climbing stairs.
Difficulty lifting your arms above your head.
Weakness that is more noticeable around the hips, thighs or shoulders than in the hands or feet.
Weakness developing gradually rather than suddenly.

Common causes

Vitamin D deficiency affecting muscle function.
An underactive or overactive thyroid gland.
Certain medications, particularly prolonged steroid treatment.
Less commonly, a primary muscle or neurological condition.

What it could be

Muscle weakness related to significant vitamin D deficiency.
Thyroid-related muscle weakness.
Steroid-related muscle weakness.
Rarely, a primary muscle or neuromuscular disorder.

What you can do while arranging assessment

Note which movements are most difficult, such as climbing stairs, rising from a chair or raising your arms.
Take sensible precautions to reduce your risk of falling.
Do not assume progressive weakness is simply part of ageing.

When to see a doctor urgently

Weakness that is severe, rapidly worsening or affecting your ability to walk safely.
Weakness associated with difficulty swallowing or breathing.

When to see a doctor

Gradual weakness affecting daily activities such as standing from a chair or climbing stairs.
Weakness occurring with bone pain or fatigue.
Risk factors such as limited sun exposure, long-term steroid therapy or known thyroid disease.

Persistent Fatigue

What you'll notice or feel

Persistent tiredness that is not fully relieved by rest or sleep.
Reduced energy for activities you would normally manage comfortably.
Fatigue occurring together with bone pain, weakness or low mood.
A gradual onset over weeks or months.

Common causes

Vitamin D deficiency.
An underactive or overactive thyroid gland.
Abnormal calcium levels related to parathyroid or other metabolic conditions.
Non-bone-related causes such as anaemia, sleep disorders or psychological factors.

What it could be

Vitamin D deficiency-related fatigue, especially when accompanied by bone or muscle symptoms.
Thyroid-related fatigue.
Fatigue associated with abnormal calcium levels.
A condition unrelated to bone metabolism, which should also be considered during assessment.

What you can do while arranging assessment

Keep a simple record of energy levels, sleep and other associated symptoms.
Maintain reasonable sleep, hydration and dietary habits.
Avoid self-diagnosing and starting high-dose supplements before appropriate testing confirms the underlying problem.

When to see a doctor urgently

Fatigue associated with chest pain, breathlessness, fainting or significant confusion.
Fatigue occurring with unexplained weight loss or night sweats.

When to see a doctor

Fatigue persisting beyond a few weeks without a clear explanation.
Fatigue occurring alongside bone pain, weakness or other metabolic symptoms.
Fatigue significantly affecting normal daily activities.

YOUR CONSULTATION

What to Expect at Your Visit

The doctor will ask about your symptoms, diet, sun exposure, medications — particularly steroid use — family history and any previous fractures.
Blood tests are often central to the assessment and may include calcium, vitamin D, parathyroid hormone, thyroid function and kidney function, depending on the clinical picture.
A bone-density scan (DEXA) may be arranged if osteoporosis or fracture risk is a concern.
X-rays or other imaging may be requested when a specific fracture or bone lesion needs assessment.
Because these conditions often overlap orthopaedic and endocrine care, treatment may involve both specialties. Supplementation, medication and monitoring will depend on the results of the investigations.

* IMPORTANT: A Note Before You Go

Symptoms such as fatigue, bone pain and weakness can have many different causes and cannot reliably diagnose a metabolic bone disorder on their own.

This information is intended to help you recognise common patterns and understand when assessment may be appropriate. Please do not start high-dose vitamin D, calcium or other supplements solely on the basis of symptoms. Appropriate investigations help determine whether treatment is needed and, if so, which treatment is suitable.
