Staying Strong: Preventing Osteoporosis During Menopause
As we age, maintaining bone health becomes increasingly important. Particularly after menopause, many people experience a decrease in bone density, which can lead to osteoporosis. This condition, characterized by brittle and fragile bones, significantly increases the risk of fractures. However, with proactive measures and informed choices, we can take steps to protect our bone health and prevent osteoporosis.
Osteoporosis is often called the "silent disease" because it progresses without noticeable symptoms until a fracture occurs. People who go through menopause are especially at risk due to the decline in estrogen levels, which play a vital role in maintaining bone density. Menopause affects not only women; it can impact all individuals with ovaries and a uterus regardless of their gender identity.
As people age, particularly after menopause, they experience a decrease in bone density, which can lead to osteoporosis.
The Importance of Early Prevention
Preventing osteoporosis should start early in life, ideally in childhood and adolescence when bone growth is at its peak. Building strong bones during these formative years can help reduce the risk of osteoporosis later in life. However, it's never too late to start taking measures to protect bone health.
Early prevention involves several key strategies:
Nutrition: ensure a diet rich in calcium and vitamin D from a young age. These nutrients are vital for bone development and strength.
Physical activity: regular physical activity, especially balance and muscle-strengthening exercises, stimulates bone growth and density.
Avoiding smoking and excessive alcohol: these habits can weaken bones.
As you approach your 50s – when menopause typically occurs – it's important to start thinking about bone mineral density (BMD) tests. These tests use x-rays to see how much light passes through bones in locations where fractures are likely to occur, such as your spine or hip. This tells your health care provider how thick or thin your bones are.
While most people start BMD testing as they reach their 50s, some people may start in earlier or later years, depending on their medical history. BMD tests are only one part of estimating your risk for bone fractures. Your health care provider will consider both your scan results as well as other details such as your lifestyle habits, family history, and if you have other medical conditions.

Calcium and vitamin D are critical nutrients for maintaining strong bones. Calcium is the primary building block of bone tissue, while vitamin D helps the body absorb calcium efficiently. Getting the right amounts of both calcium and vitamin D are an important part of preventing osteoporosis.
Calcium: the recommended daily intake of calcium varies by age.
For adults aged 50 and younger, 1,000 mg per day is generally sufficient, while those over 50 should aim for 1,200 mg per day. Ask your health care provider to see how much calcium you need if you are pregnant or breast-feeding.
Good dietary sources of calcium include dairy products like milk, cheese, and yogurt, as well as leafy green vegetables, nuts, and fortified foods.
Vitamin D: the recommended daily intake of vitamin D is 600 IU for adults up to age 70, and 800 IU for those over 70.
While sun exposure is a natural source of vitamin D, it can also be obtained from foods such as fatty fish, egg yolks, and fortified dairy products.
Because of limited sun exposure in Canada, reduced vitamin D production with age, and low amounts of vitamin D from our diet, it's recommended that most Canadian adults receive vitamin D supplements year-round.
Regular physical activity is another important part of osteoporosis prevention. Balance, muscle-strengthening, and functional exercises are particularly effective in building and maintaining bone density.
Balance exercises help us to stay steady when you're in unstable body positions, lowering your risk of falls and fractures. Different types of balance exercises can help to improve your balance in various situations, so be sure to try a mix of them.
Shifting your weight: within your limits, lean from side-to-side or from your toes to your heels while standing up. Be sure to have a support object nearby to keep you from falling.
Reacting to unpredictable movements: engage in activities that challenge your balance in unexpected ways. This could include playing catch with balls of different sizes and weights, which requires you to adjust your position quickly and unpredictably.
Engaging in dynamic balance activities: participate in activities that require you to maintain balance while moving. For example, Tai Chi or line dancing are excellent choices.
Reducing your base of support: practice exercises that involve standing on one foot or otherwise reducing your base of support. Try doing yoga poses or simply lifting one foot off the ground while brushing your teeth.
Muscle-strengthening exercises, also known as resistance training, involve lifting weights or using resistance bands to build muscle mass and strength. Strong muscles support and protect bones, reducing the risk of fractures.
Weight lifting: incorporating free weights, weight machines, or resistance bands into your fitness routine helps build strength. Aim for at least 2 days of resistance training per week, focusing on all major muscle groups.
Bodyweight exercises: exercises such as push-ups, squats, and lunges use your body weight to build strength and can be done anywhere without special equipment.
Lastly, functional exercises are those that help us to perform important activities in our day-to-day lives. These are as simple as doing chair stands to stand up from a chair more easily or climbing stairs to prepare for hikes.
Maintaining bone health is a lifelong commitment, especially for people going through menopause. By understanding your risk factors for osteoporosis and taking proactive steps such as ensuring adequate intake of calcium and vitamin D, engaging in regular balance and muscle-strengthening exercises, and undergoing regular bone health assessments, you can significantly reduce your risk of osteoporosis and enjoy a healthy, active life.
