Can levothyroxine cause bone loss?
Bone loss due to levothyroxine over-replacement frequently occurs in postmenopausal women [11,12]. However, evidence of an association between levothyroxine doses and fracture risk has been insufficient. A recent epidemiological study by Turner et al.
Does thyroid medication deplete calcium?
If the hyperthyroidism is treated early, bone loss can be minimized. In the same manner, excessive amounts of thyroid hormone replacement medication can also result in bone loss. In addition to osteoporosis, hyperthyroidism can cause blood calcium levels to rise (hypercalcemia) by as much as 25%.
What are the long term effects of taking thyroid medication?
If the levothyroxine dose is too high, serious side effects can occur, mainly affecting the heart, and include (DailyMed, 2019):…
- Irregular heartbeat (arrhythmia)
- High blood pressure.
- Heart failure.
- Chest pain (angina)
- Heart attack (myocardial infarction)
- Cardiac arrest (heart stops working)
Does levothyroxine reduce bone density?
The present study also showed that at the time of diagnosis of hypothyroidism, BMD was not significantly different from normal subjects. Interestingly, the patients that received 2 years of levothyroxine replacement therapy had lower bone density.
Can thyroid cause bone problems?
High levels of thyroid hormones, or hyperthyroidism, cause rapid bone loss, and new bone might not be as strong as the bone lost. This process of increased bone loss over time causes osteoporosis. Hypothyroidism, which slows your body’s metabolism, also slows down your bone’s metabolism.
Can hypothyroidism cause bone loss?
If your hypothyroidism treatment raises your thyroid levels too high for a sustained period, you may develop bone loss and osteoporosis. That is one reason why periodic blood tests to measure thyroid function are so important—thyroid hormone levels can be affected by different changes, such as diet and body weight.
How does hypothyroidism increase bone density?
Overt hypothyroidism is known to lower bone turnover by reducing both osteoclastic bone resorption and osteoblastic activity. These changes in bone metabolism would result in an increase in bone mineralization.
Is calcium good for hypothyroidism?
Yes. Calcium supplements — or antacids containing calcium — can interfere with the absorption of thyroid hormone replacement medications, such as synthetic thyroid hormones levothyroxine (Synthroid, Unithroid, others) and liothyronine (Cytomel), as well as thyroid extract supplements.
What causes rapid loss of bone density?
However, there are a number of medical conditions and medications that can cause more rapid bone loss — the most common conditions are hyperparathyroidism, hyperthyroidism, vitamin D deficiency and celiac disease, and the most common medications are steroids and aromatase inhibitors.
What is considered rapid bone loss?
Rapid bone loss was defined as an annualized bone loss rate of at least 1 standard deviation (SD) of the sex-specific loss rate at each skeletal site.
What diseases cause low bone density?
Not only do bones lose density with age, medications used to treat breast cancer, arthritis, asthma, Crohn’s disease and Addison’s disease can also lower bone density. Some illnesses such as hyperthyroidism, hypopituaritism and eating disorders also cause bones to lose strength.
What is normal bone density for a 50 year old female?
Analysis of the mean bone density scores showed a confidence interval (at level of significance 95%) of 1.159 g/cm2 to 1.185 g/cm2 for women aged 40-44 years and 1.105 g/cm2 to 1.141 g/cm2 for women aged 50-54 years.
Does bone density affect weight?
Confusion exists concerning the effects that weight loss has on bone health. Recent findings: Bone density is more closely associated with lean mass than total body mass and fat mass.
Does losing weight lower bone density?
Bone mineral density decreases with diet-induced weight loss [18–20], and at least in post-menopausal women, does not return to pre-weight loss levels with weight regain [20].
How long does it take to lose bone density?
Your entire skeleton is replaced about every 10 years, though this process slows as you get older. As long as your body has a good balance of new and old bone, your bones stay healthy and strong. Bone loss occurs when more old bone is reabsorbed than new bone is created.
