Does taking cortisone long-term weaken your bones?
Long-term cortisone use demonstrably weakens your bones; if you use it long-term, it is wise to discuss with your doctor whether you are a candidate for bisphosphonates as a protective measure.
Yes, taking cortisone long-term weakens your bones. With prolonged use, up to 50% of patients face an increased risk of vertebral fractures. The effect works in two directions: the cells that build new bone are suppressed, while the cells that break bone down become more active. This has been recognised for decades as one of the most serious side effects of long-term corticosteroid therapy.
Cortisone also disrupts calcium balance. Your intestines absorb less calcium from food, and your kidneys let more calcium wash out through urine. In response, your body produces more parathyroid hormone, and that hormone further accelerates bone breakdown.
Not everyone faces the same level of risk. People who have taken more than 10 grams of cortisone in total, are older than 50, or already had low bone density before treatment are the most vulnerable. Smoking, excessive alcohol use, low levels of physical activity, and low sex hormone production increase the risk further. Notably, in cortisone-related bone loss, fractures occur mainly in the spine and ribs rather than the hip, which distinguishes it from other forms of osteoporosis.
There are medications that can slow bone loss. Bisphosphonates are the best supported for both prevention and treatment. Calcitonin (nasal spray) and active vitamin D can improve bone density in the spine, but the evidence for this is less robust. Calcium and vitamin D alone are insufficient. They work best as a supplement to other medications.
An important caveat: although bisphosphonates and other medications measurably improve bone density, studies to date have not shown that they also reduce the number of actual fractures in people who use cortisone long-term. Whether improved bone density truly translates to fewer fractures has therefore not yet been proven in this specific context.
All sources are reviews; no randomised trials or meta-analyses are included in the supplied set. However, the causal relationship between corticosteroid use and bone loss is broadly recognised across multiple independent reviews.
Does drinking a lot of alcohol weaken your bones?
Chronic heavy drinking demonstrably weakens your bones and substantially raises the risk of a hip fracture; for your bones there is no safe level above two drinks per day.
Does a vegetarian diet weaken your bones?
A vegetarian diet does not automatically weaken your bones, but as a vegan you need to pay extra attention to calcium and vitamin B12. Ensure adequate supplementation of both and the increased fracture risk can largely be prevented.
Can statins (cholesterol-lowering medications) affect your bones?
Statins show positive effects on bone in laboratory and animal research, but randomised trials in humans do not confirm this. There is therefore no need to reconsider your cholesterol medication for the sake of your bones, but do not expect any bone protection from it either.
Do carbonated drinks damage your bones?
Regularly drinking large amounts of sugary carbonated drinks is associated with lower bone density, especially in women and during puberty. Moderate consumption appears less harmful, but it is preferable to replace soft drinks with beverages that support bone development.
Do you really need calcium supplements for strong bones?
Whether you need calcium supplements depends strongly on your age and circumstances: for young, healthy women there is no evidence of benefit, while people over 50 may benefit from calcium plus vitamin D, provided the increased risk of kidney stones is taken into account.
What happens to your bones when you lie in bed for a long time?
Prolonged bed rest demonstrably leads to substantial bone loss, particularly in the hip, spine and heel bone. Recovery takes much longer than the period of bed rest itself, so resuming movement as soon as possible is the best thing you can do.
