Bone Health Impacts and Maintaining Bone Mass During Menopause

During menopause, reduced oestrogen levels accelerate bone resorption while diminishing bone formation, leading to a net loss in bone mass. This process heightens the risk of osteoporosis, fractures, and long-term skeletal complications, making proactive bone health management essential during this stage of life.

Impacts of Menopause on Bone Health

Bone density begins to decrease naturally with age, but menopause accelerates this process. Women can lose up to 20% of their bone mass in the first five to seven years following menopause (Riggs et al., 2002). Osteopenia, a precursor to osteoporosis, is often diagnosed during this time. The most commonly affected sites are the hip, spine, and wrist, where fractures are more likely to occur.

Fractures can lead to significant morbidity, including chronic pain, reduced mobility, and increased dependence on caregivers. Vertebral fractures, in particular, can cause height loss, kyphosis (a hunched back), and impaired respiratory function. The economic and social burden of osteoporosis and related fractures is substantial, highlighting the importance of preventive strategies.

Strategies to Maintain Bone Mass During Menopause

1. Adequate Calcium and Vitamin D Intake
Calcium and vitamin D are vital for bone health. Postmenopausal women are advised to consume 1,200 mg of calcium daily from dietary sources such as dairy products, fortified plant-based milk, almonds, broccoli, and leafy greens (Ross et al., 2011). Vitamin D enhances calcium absorption and supports bone remodelling. The recommended daily intake for vitamin D is 600–800 IU, though higher doses may be necessary in individuals with vitamin D deficiency or limited sun exposure. Fatty fish, egg yolks, and fortified foods are good dietary sources.

2. Weight-Bearing and Resistance Exercises
Physical activity is essential for maintaining bone density. Weight-bearing exercises, such as walking, jogging, and dancing, stimulate bone remodelling by increasing mechanical stress on bones. Resistance training, including lifting weights or using resistance bands, strengthens both muscles and bones, reducing the risk of falls and fractures (Howe et al., 2011). Incorporating balance and flexibility exercises, like yoga or tai chi, can further improve stability and prevent falls.

3. Lifestyle Modifications
Avoiding smoking and excessive alcohol consumption is critical for bone health. Smoking accelerates bone loss, while excessive alcohol intake disrupts calcium absorption and bone remodelling. Maintaining a healthy body weight is also important, as both underweight and obesity are associated with poor bone health.

4. Menopause Hormone Therapy (MHT)
Hormone therapy can help maintain bone density by supplementing estrogen levels. Studies show that HT effectively reduces bone loss and fracture risk in postmenopausal women (Manson et al., 2015). However, MHT should be considered on an individual basis.

5. Bone-Supportive Medications
For women at high risk of osteoporosis, medications such as bisphosphonates, selective oestrogen receptor modulators (SERMs), or denosumab may be recommended to slow bone loss and improve bone density.

6. Nutritional Support
Adequate protein intake is necessary for bone and muscle health. Protein-rich foods such as lean meats, fish, eggs, and legumes support the bone matrix. Additionally, magnesium, zinc, and vitamin K contribute to bone strength and should be included in a balanced diet.

Conclusion

Menopause is a critical time to focus on bone health due to the accelerated loss of bone mass associated with estrogen deficiency. A comprehensive approach combining proper nutrition, regular exercise, lifestyle modifications, and, if necessary, medical interventions can help maintain bone density and reduce the risk of osteoporosis and fractures. Proactive management of bone health ensures improved quality of life and independence during and after the menopausal transition.
