3. Long-Term Corticosteroid Use
Long-term use of corticosteroids like prednisone can cause significant bone loss, often leading to secondary osteoporosis. These medications suppress bone formation and increase bone resorption, disrupting the delicate balance that maintains bone strength. The risk escalates with the dose and duration, particularly when steroids are taken for months or years.
People on long-term corticosteroids for conditions such as asthma, rheumatoid arthritis, or autoimmune diseases should be closely monitored for bone health. Preventative measures might include calcium and vitamin D supplementation, lifestyle changes, and possibly prescription medications to protect bones.
Importantly, patients should never stop corticosteroids without consulting their prescriber, as abrupt discontinuation can have serious health consequences.
4. Bone-Impacting Medications
Several medications not commonly associated with bone health can contribute to bone loss when used long-term. These include:
- Proton pump inhibitors (acid reflux drugs) that may reduce calcium absorption.
- Selective serotonin reuptake inhibitors (SSRIs) used for depression.
- Aromatase inhibitors prescribed for breast cancer, which lower estrogen levels.
- Certain diabetes medications that may affect bone remodeling.
Patients taking these medications should inform their healthcare providers about their bone health, especially if other risk factors are present. Bone density screening can help detect early bone loss and guide any necessary interventions.
5. Smoking and Low Body Weight
Smoking is a well-established risk factor for osteoporosis. It impairs blood supply to bones, reduces calcium absorption, and can interfere with the production of bone-forming cells. Additionally, smoking accelerates estrogen loss in women, compounding bone loss after menopause.
Low body weight also increases fracture risk because less mechanical load on bones results in less stimulus for bone maintenance. Furthermore, people with low body fat often have lower estrogen levels, which hastens bone loss.
For those who smoke or have low body weight, bone density testing is especially important to identify early osteoporosis. Lifestyle changes such as smoking cessation and maintaining a healthy weight can support better bone health alongside medical management.
