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.
Can hypothyroidism affect your bones?
This process of increased bone loss over time causes osteoporosis. Hypothyroidism, which slows your body’s metabolism, also slows down your bone’s metabolism. In people with hypothyroidism, the bone formation process is slowed 50 percent, and bone resorption 40 percent.
Can thyroid problems affect bone density?
What is the link between thyroid disease and osteoporosis? Thyroid hormone affects the rate of bone replacement. Too much thyroid hormone (i.e. thyroxine) in your body speeds the rate at which bone is lost. If this happens too fast the osteoblasts may not be able to replace the bone loss quickly enough.
Does thyroid medicine weaken your bones?
Most patients on thyroid medicine have Hashimoto’s thyroiditis and a smaller number take thyroid medicine because of thyroid cancer or Graves disease. Too much thyroid medicine increases the activity of the osteoclasts (the bones that break down bone) and put you at an increased risk for breaking a bone.
Can an underactive thyroid cause osteoporosis?
Underactive thyroid (hypothyroidism)
An underactive thyroid is not, in itself, a risk factor for osteoporosis, but if you are prescribed levothyroxine to increase your thyroid levels to the normal range you should have regular blood tests, at least once a year, to ensure your thyroid hormone levels are not too high.
Can thyroid cause bone pain?
People with advanced hypothyroidism may find that fluid builds in joints as their metabolism slows — and that causes swelling that, the Mayo Clinic points out, can lead to pain.
Is calcium good for hypothyroidism?
Answer From Todd B. Nippoldt, M.D. 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.
Does hypothyroidism cause vitamin D deficiency?
Some, but not all, observational studies have found low blood levels of vitamin D in patients with hypothyroidism (underactive thyroid) as well as hyperthyroidism (an overactive thyroid) due to Gravesʼ disease.
Does vitamin D affect thyroid medication?
No interactions were found between levothyroxine and Vitamin D3. This does not necessarily mean no interactions exist. Always consult your healthcare provider.
Is levothyroxine bad for the bones?
In this nationwide retrospective cohort study on the association between the levothyroxine dose and fracture risk among elderly women (aged ≥65 years), we found a significant association between a higher dose of levothyroxine (>150 µg/d) and fracture risk in the highly probable osteoporosis subgroup.
What are the long term side effects of levothyroxine?
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 problems cause osteoarthritis?
Hypothyroidism has been associated with osteoarthritis (OA) and inflammatory forms of arthritis and with several well defined connective tissue diseases, which in turn can cause arthritis. The presence of arthritis in patients with AITD with normal thyroid function is now being increasingly recognized.
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%.
