Bones form the body’s structural framework, giving it shape, protecting vital organs, and enabling movement. Made of hard, calcified tissue, proteins, and minerals, bones have a rigid outer layer and a spongy marrow core that produces blood cells. The adult skeleton has 206 bones that also store essential minerals. Bone density, which measures mineral content, determines bone strength. It peaks around age 25 and gradually declines after 35, raising the risk of fractures and osteoporosis particularly in postmenopausal women due to reduced estrogen levels.
Keeping bones healthy involves building strong bone mass early in life and protecting it as you age. Strength training, weight-bearing exercises, and regular physical activity help maintain bone strength. A diet rich in calcium (from dairy or leafy greens) and vitamin D (with safe sun exposure) supports bone health. It’s also important to limit carbonated beverages, as excess phosphorus can weaken bones. Older adults should remove trip hazards at home and consider assistive devices if balance is an issue. Regular bone density checks after age 50 can detect early signs of osteoporosis so that preventive steps, including supplements or medications, can be taken to reduce fracture risk and support healthy aging.
The bones are the structural support system of the body. They provide rigidity and give the body its shape. The bones are made of hard calcified tissue, proteins and minerals. They have a hard outer layer which provides structure and rigidity, and a spongy inner core (bone marrow) that produces new blood cells. The bones also have subhondral tissue on the smooth ends – This is covered in cartilage which is a rubbery connective tissue in the joints. The adult body has 206 bones that make up the skeletal system. The skeletal system is a remarkably efficient design – It protects the delicate internal organs, makes movement possible, produces blood cells in the bone marrow and functions as a storage site for minerals within a very minimal space.
The human skeleton performs many functions, and bones in different places have different shapes to perform their specific function. The bones in the human body are classified into 5 types:
Flat Bones – The flat bones can be described as thin, flat “plates” made of bone tissue. The flat bones follow the contours of the body. Their main function is to protect the delicate internal organs, like the brain. The flat bones make up the skull, the rib cage and the pelvis. Flat bones also provide a large surface area, that multiple muscles can attach to.
Long Bones – The long bones are probably the shape you immediately associate with bones – a long shaft with 2 expanded ends. They are significantly longer in length compared to width. The long bones are like the pillars of your body, and their primary role is to support the weight of the body and facilitate movement. The expanded ends of the long bones are shaped that way to support the joints. Examples of long bones include the tibia, fibula, femur, humerus, radius, metatarsals and phalanges.
Short Bones – The short bones are roughly “cube-shaped”. They are as long as they are wide. The short bones provide stability and support movement. They are mostly located in the wrist (carpals) and ankle joints (tarsals).
Sesamoid Bones – The sesamoid bones are small, bone-like structures embedded within tendons, usually near joints where they cross long bones. They act as spacers to change the angle of the tendons before they reach the point of attachment to the bone. Their main function is to protect the tendons from excessive wear and tear.
Irregular Bones – The irregular bones have unique, complex shapes suited to their individual function. They are highly specialized, and don’t fall into any of the other 4 categories. The vertebrae that make up the spinal cord are examples of irregular bones.
Bone density is a measure of the calcium, phosphorus and other minerals contained in a specific volume of bone. Bone density accounts for about 60% of bone strength. Normally, bone density increases from childhood and peaks at about 25 years of age. This is when your bones are at their strongest. After 35, bone density begins to decline steadily, usually at the rate of about 0.3 to 0.5% per year.
Bones are not totally solid – They have a honey-comb structure in the middle. This helps them achieve optimal strength, while still staying lightweight. When bone density reduces, the honeycomb structure becomes more hollow. This compromises bone strength and increases the risk of fracture.
Low bone density is a global problem. Osteoporosis is a degenerative condition that weakens your bones, reducing density and thickness. This makes bones prone to fracturing, even under small forces. Osteoporosis is a silent disease, and often people don’t realize they have it until it causes a fracture. If you are above the age of 50 or have a family history of osteoporosis, it is recommended that you speak to your family doctor about bone density. Experts estimate that 1 in 2 women and 1 in 4 men above the age of 50 have some degree of osteoporosis. People with endocrine disorders (like thyroid disease and diabetes), gastrointestinal disorders (like IBD or celiac disease), arthritis or cancers are more likely to have osteoporosis. People who smoke also face a higher risk.
Older women have an elevated risk of osteoporosis. Estrogen plays an important role in keeping your bones strong. Estrogen production reduces significantly after menopause, making post-menopausal women more vulnerable to fractures. They also tend to have poorer joint health, often experiencing knee pain, hip pain or shoulder pain. Older women can, however, take steps to strengthen their bones using a combination of diet, exercise and lifestyle choices. Calcium (and vitamin D that assists in calcium absorption) can help bone building and maintenance. It is recommended to include dairy products, leafy greens, in your diet. You should also get about 10 to 15 mins of sunlight exposure, for vitamin D. Bone health also benefits from getting at least 30 minutes of exercise every day.

Bone fractures, basically broken bones, are a common injury and can happen to you at any age. Fractures are usually caused by accidents, falls, overuse or repetitive force, and need urgent medical attention. If you fall down or sustain a traumatic injury, you should visit the emergency room immediately. Fractures are of different types and are classified according to:
Bone fractures are diagnosed using imaging tests, usually X-ray scans. Broken bones usually need to heal on their own. This is a process that typically takes 6 to 8 weeks. However, before the bone heals, the broken segments of bone need to be realigned properly and set into place. This is to ensure that the healed bone is aligned correctly, for proper function. The fracture is also usually protected by an external cast during the entire healing period, to protect the fracture from any further damage, and to hold the broken bones in correct alignment. Sometimes, complex fractures need surgical intervention. The broken bones have to be re-aligned in an open procedure and fixed into place with a combination of titanium rods, plates, pins and screws. If a bone isn’t healing well on its own, a bone graft surgery may also be performed. This is when healthy bone tissue is transplanted to the site of injury, to speed up healing.
Clearly, good bone health is critical to aging well. A person’s bone density must be built up when they are young and then maintained throughout their adult life. This is a long-term process and there are no quick fixes if it is neglected early in life. However, there are lifestyle changes and good practices you can follow to minimize further depletion of bone density, and safeguard your bones:
Strength Training – Putting your bones through a healthy amount of load will strengthen them over time. This is why strength training is recommended for everyone, within supervised limits. People above the age of 45 are recommended 3 moderate-intensity strength training sessions per week. You could opt to use free weights or resistance bands, but form is very important. The focus is not on how much weight you can move, but how you do it with proper alignment. If you are a novice, a coach or personal trainer is recommended, so you can stay safe while you work out.
Avoid Carbonated Beverages – Carbonated beverages have phosphorus in them. This leeches calcium out of the bones, weakening them and making them vulnerable to cracks and fractures. Diet sodas may not have sugar, but they’re still bad for your bones. Try not to drink more than 1 can of carbonated beverages per week.
Adequate Calcium Intake – Make sure you’re getting enough calcium by including more dairy and leafy greens in your diet. If you are allergic to dairy, we suggest speaking to your family doctor about it – They will prescribe supplements if needed. Make sure you also get enough vitamin D and sunlight exposure, so your body actually absorbs the calcium you are eating. Menopausal and post-menopausal women need calcium supplements, because the reduction in estrogen production diminishes their body’s capacity to absorb it from food.
Remove Trip Hazards in Daily Environments – If you are above the age of 50, you are more likely to experience a fall that results in a fracture. Reduce this risk by performing a risk assessment of your home, workplace, and any other spaces you regularly spend time in. Walk around and check for trip hazards. Rugs, loose power cords along the floor and dimly lit spaces can be risky. Make sure wet areas, like the bathroom, have rough tile installed for grip.
Use assistive device if you need them – If you have difficulty with balance or mobility, there is no shame in using an assistive device. This could be a cane, a crutch, a walker or a wheelchair – Whatever makes you feel stable and comfortable while you move around. There is a bit of a learning curve while you get used to the device, but it will keep you safe in the long run.
Exercise Caution – Be careful! Avoid risky behaviour, and do not try to do too much by yourself. Always watch where you are going, being present in the moment. Don’t carry heavy objects on your own, and don’t try to do physically demanding tasks beyond your capability. It’s ok to acknowledge your limits and ask for help.
Check your Bone Density – At your next routine health check-up, speak to your doctor about bone density. They will perform a bone density scan and advise you accordingly. Depending on the results, you may be given supplements or medication to help you maintain or improve bone density. This is a pre-emptive strategy.
Strong bones are the foundation of an active and healthy life.

At what age should I start worrying about bone health?
Bone health actually starts early. Peak bone strength is reached by around 25, and after 35 it slowly declines. Building strong bones early and maintaining them with diet and exercise is key to preventing future problems.
How do I know if I have low bone density or osteoporosis?
Most people don’t feel symptoms until a fracture occurs. The safest way is a bone density scan (DEXA), especially after age 50 or if you have risk factors like menopause, diabetes, or family history.
What are the early warning signs of weak bones?
There are usually no clear early signs. However, frequent fractures, loss of height, back pain, or poor posture can indicate weakened bones and should be evaluated by a doctor.
What is the best way to strengthen bones naturally?
Regular weight-bearing exercises like walking, strength training, and a diet rich in calcium and vitamin D are the most effective. Consistency over time is more important than quick fixes.
Do calcium supplements really help improve bone health?
They can help if your dietary intake is low, especially in older adults and postmenopausal women. However, supplements should be taken under medical guidance to ensure proper dosage and absorption.
Are women at higher risk of osteoporosis than men?
Yes, especially after menopause. The drop in estrogen levels reduces bone density faster, making women more prone to fractures compared to men of the same age.
Can lifestyle habits like soda consumption affect bone strength?
Yes, excessive intake of carbonated drinks can interfere with calcium balance and weaken bones over time. Limiting such habits plays a role in long-term bone health.
When should I consult a doctor for bone health concerns?
If you are over 50, have frequent joint pain, a history of fractures, or risk factors like menopause or chronic illness, it’s best to consult a specialist for evaluation and preventive care.
