Halloween is often associated with skeletons, but how often do we think about the living skeleton that supports us every day?
Our bones are much more than a rigid framework. They are living tissue that continually renews itself, supports movement, protects vital organs and stores essential minerals. Alongside our joints and muscles, they help us maintain strength, mobility and independence throughout life. As we age, looking after bone health becomes increasingly important. The good news is that everyday habits, including nutrition, physical activity and appropriate healthcare, can all contribute to healthier bones and muscles.
Understanding Osteopenia, Osteoporosis and Osteoarthritis
These terms are often confused, but they describe different conditions.
Osteopenia: Lower Bone Density
Osteopenia describes bone mineral density that is lower than normal but not low enough to meet the diagnostic threshold for osteoporosis. It can indicate an increased risk of future bone loss and fractures, although not everyone with osteopenia will develop osteoporosis. A bone-density assessment can help identify reduced bone density and inform decisions about prevention and monitoring.
Osteoporosis: Weakened Bones
Osteoporosis is a condition in which bones become less strong and more vulnerable to fractures. It is often called a silent condition because bone loss can occur without noticeable symptoms. For some people, the first indication may be a fracture following a relatively minor fall or injury. Risk can be influenced by age, hormonal changes, family history, certain medical conditions, lifestyle factors and some medicines. Recognising risk factors and discussing them with a healthcare professional can help determine whether further assessment is appropriate.
Osteoarthritis: A Condition Affecting the Joints
Osteoarthritis is different from osteoporosis. It affects the whole joint, including cartilage, the underlying bone and surrounding tissues. Symptoms may include pain, stiffness, swelling and reduced movement. Although osteoarthritis becomes more common with age, symptoms and their impact vary between individuals. Appropriate exercise, strength-building activities, symptom management and professional guidance can help people maintain function and quality of life.
Don't Forget Your Muscles
Bone health is only one part of maintaining mobility as we age. Muscle strength and balance are equally important. Age-related loss of muscle mass and strength is known as sarcopenia. It can affect everyday activities such as climbing stairs, carrying shopping and getting up from a chair. Stronger muscles help support movement and stability, while balance training can help reduce the risk of falls. Maintaining muscle strength is therefore an important part of protecting independence as well as supporting overall musculoskeletal health.
Bone Health and Essential Nutrients
Bones need a range of nutrients to maintain their structure and function. A balanced, varied diet is a good starting point.
- Calcium is a major mineral component of bone and helps maintain its strength. Sources include dairy products, calcium-fortified alternatives, calcium-set tofu and certain leafy green vegetables.
- Vitamin D helps the body absorb calcium and supports normal muscle function. Dietary sources include oily fish, egg yolks and some fortified foods. In Ireland, vitamin D intake deserves particular attention, especially during the darker months. Ask your pharmacist or healthcare professional about appropriate supplementation for your circumstances.
- Phosphorus works with calcium to form the mineral structure of bone. It is found in foods such as dairy products, fish, meat, eggs, beans and nuts.
- Magnesium contributes to normal bone and muscle function. Sources include nuts, seeds, wholegrains, legumes and leafy green vegetables.
- Protein provides the building blocks needed to maintain muscle and contributes to the structure of bone. Useful sources include eggs, fish, dairy products, lean meat, beans, lentils, tofu and other pulses.
No single nutrient or food can guarantee strong bones. The overall pattern of eating, together with activity and other lifestyle factors, matters most.
Food Choices and Bone Health
Consistently eating too little or following a highly restrictive diet can make it harder to obtain the energy, protein, vitamins and minerals the body needs.
Factors that may affect bone and muscle health include:
-
Inadequate calorie or protein intake.
-
Low calcium or vitamin D intake.
-
Frequently skipping meals or following extreme diets.
-
Limited dietary variety.
-
Excessive alcohol consumption.
-
Replacing nourishing foods too frequently with foods that offer limited nutritional value.
This does not mean that any particular food needs to be avoided completely. Instead, aim for a sustainable eating pattern that includes a variety of nutrient-rich foods and provides enough energy to support your needs. Food should generally be the foundation of nutritional care. Supplements may be useful when intake is inadequate or a deficiency or increased need has been identified, but they are not automatically necessary for everyone.
Movement: Give Your Bones and Muscles a Reason to Stay Strong
Bones respond to the demands placed on them. Suitable physical activity helps support bone strength, muscle function and mobility. Helpful activities can include:
-
Weight-bearing exercise: Activities such as brisk walking, dancing and suitable forms of hiking.
-
Resistance training: Exercises using weights, resistance bands or body weight to help maintain muscle strength.
-
Balance exercises: Activities that improve stability and coordination.
-
Flexibility and mobility work: Movements that support comfortable movement and everyday function.
The right activities depend on your age, current fitness, medical history and any existing bone or joint conditions. If you have osteoporosis, a history of fractures, significant joint pain or concerns about falls, ask a healthcare professional or appropriately qualified exercise professional for advice before starting a new programme. Consistency is more useful than an occasional intense workout. Choose activities that are appropriate for your circumstances and that you can maintain over time.
Medicines and Your Bones
Some medicines can affect bone density or the risk of fractures. The potential effect depends on the medicine, dose, duration of use and individual risk factors. Examples include:
-
Certain corticosteroid medicines, particularly when taken orally at higher doses or over long periods.
-
Some anti-seizure medicines.
-
Certain breast and prostate cancer treatments.
-
Some medicines used for acid reflux, particularly with long-term use and other risk factors.
-
Certain antidepressants, although the reasons for the observed association with fractures are not always clear.
This does not mean that these medicines are unsuitable or should be avoided. They may be important for treating or managing other conditions, and their benefits may outweigh potential risks. Never stop or change prescribed medication without medical advice. If you are concerned, ask your GP or pharmacist whether your medication affects your bone health and whether any monitoring, nutritional support or further assessment is appropriate.
When Might a Bone-Health Assessment Be Appropriate?
A bone-density scan, commonly called a DXA scan, measures bone mineral density. It can help healthcare professionals assess bone health and inform decisions about fracture risk and treatment. Whether a scan is appropriate depends on individual circumstances. Factors such as age, previous fractures, family history, certain medical conditions, hormonal changes and some medicines may influence the decision. If you have concerns about bone health, have experienced a fracture following a minor injury or have noticed changes in mobility, discuss these with your GP or healthcare professional. They can advise whether further assessment is needed. Persistent joint pain, increasing stiffness or difficulty with everyday movement should also be discussed with an appropriate healthcare professional rather than simply attributed to ageing.
Looking After Your Skeleton: Small Steps Matter
Supporting bone, joint and muscle health does not depend on one supplement, one exercise or one superfood. It is the combination of habits over time that makes a difference. Consider these practical steps:
-
Include regular, appropriate weight-bearing activity.
-
Add resistance and strength exercises suited to your ability.
-
Work on balance and mobility.
-
Eat a varied diet with sufficient calcium, vitamin D, protein and other essential nutrients.
-
Avoid smoking and keep alcohol consumption within recommended limits.
-
Review concerns about medicines with your doctor or pharmacist.
-
Ask about bone-health assessment if you have relevant risk factors.
