What is osteoporosis?
“Osteoporosis is a bone disease that develops when bone mineral density and bone mass decreases, or when the structure and strength of bone changes. This can lead to a decrease in bone strength that can increase the risk of fractures (broken bones)”. (National Institute of Arthritis and Musculoskeletal and Skin Diseases: https://www.niams.nih.gov/health-topics/osteoporosis).
Recommendations to prevent osteoporosis: these recommendations may slow, but not do prevent, bone loss:
- Sufficient calcium, magnesium, Vitamin K, and Vitamin D, preferably from food. (There is very little benefit to taking Vitamin D doses greater than 600-800 IU/day).
- Weight-bearing exercise: 150 minutes/week.
- Nutrient rich diet with at least 1.2g protein/kg of body weight, plenty of green leafy vegetables, legumes/beans, fruits, grains, and fermented, low fat, dairy.
- Estrogen and estrogen plus progestin prevented both vertebral and hip fracture in women with an average age of 63-years and did not have osteoporosis in the Women’s Health Initiative study (See reference below).
Risk factors for osteoporosis:
- Personal or family history of fracture.
- Certain medical conditions: Rheumatoid arthritis, Cushing syndrome, chronic renal disease, anorexia nervosa, hyperthyroidism, Type 1 Diabetes mellitus, Hemochromatosis, and chronic liver disease, among others.
- Certain medications: Aromatase inhibitors (used in the treatment of breast cancer), immunosuppressants, excessive thyroxine doses, and phenytoin, among others.
-
- Caucasian, thin, petite build, advanced age, sedentary lifestyle, excessive alcohol intake, and genetics.
Medications often prescribed to treat or manage osteoporosis: these should be prescribed/managed by a specialist:
- Estrogens (if not otherwise, contraindicated).
- Bisphosphonates (Raloxifene, Risedronate, Alendronate, Etidronate, and Ibandronate orally).
- Estrogen agonists/antagonists (SERMs) (Bazedoxifene/conjugated estrogen combo).
- RANK ligand inhibitor (Denosumab subcutaneously).
- Salmon calcitonin (subcutaneously or nasal).
- PTH-receptor agonists (Teriparatide, Abaloparatide subcutaneously).
What is osteopenia?
Osteopenia is bone density loss. It can progress to osteoporosis if the bone density loss worsens.
