Does thyroid medicine cause bone loss?
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
.

The long-term effects of thyroid medication include
weight fluctuations, sensitivity to heat, joint pain, changes to your menstrual cycle, and possibly even autoimmune dysfunction

Does taking thyroxine cause osteoporosis?
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.
Can Synthroid affect your bones?
A study of Korean women over 65 looked at the relationship between a higher dose of levothyroxine and the risk of bone fractures. They found that
women who were already at an increased risk for osteoporosis experienced more bone fractures if they took higher doses of levothyroxine
(Ko, 2014).
Can levothyroxine affect bone density?
Interestingly,
the patients that received 2 years of levothyroxine replacement therapy had lower bone density
. Thus, simultaneous treatment of hypothyroidism and bone loss seems to be necessary.
Can levothyroxine worsen osteoporosis?
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.

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.
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%
.
Does low thyroid affect bone density?
Thyroid hormones play an important role in bone mineral homeostasis and bone density.
Both hyperthyroidism and, to some extent, hypothyroidism are associated with reduced BMD
leading to increased fracture risk.
Does low TSH cause bone loss?
There is also
some evidence that people with low TSH levels may lose bone at a faster rate than those with normal TSH levels
even when the blood thyroxine measurement is within the normal range, but this is still being studied.
How long can you take levothyroxine?

Can thyroid problems cause osteoporosis?
Thyroid hormones are essential for normal skeletal development and normal bone metabolism in adults but can have detrimental effects on bone structures in states of thyroid dysfunction.
Untreated severe hyperthyroidism influences the degree of bone mass and increases the probability of high bone turnover osteoporosis
.
What medication causes osteoporosis?
The medications most commonly associated with osteoporosis include
phenytoin, phenobarbital, carbamazepine, and primidone
. These antiepileptic drugs (AEDs) are all potent inducers of CYP-450 isoenzymes.
Do thyroid patients need 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.
Is 25 mcg levothyroxine a lot?
There are two strategies for initiating levothyroxine in healthy adults younger than 65 years: low-dose (50 mcg) and full-dose (1.6 to 1.7 mcg per kg). Traditionally,
lower starting doses of 25 to 50 mcg per day are recommended for patients 65 years and older or who have ischemic heart disease
.
What else can I take instead of levothyroxine?
Liothyronine (Cytomel, Tertroxin)
is a synthetic version of T3 and levothyroxine (Synthroid, Levothroid, Levoxyl) is a substitute for T4. If your hypothyroidism is caused by an iodine deficiency, your doctor may recommend an iodine supplement.

Can hypothyroidism cause arthritis?

people with the most common form of hypothyroidism have a higher risk of developing other autoimmune diseases, such as rheumatoid arthritis
. If pain, stiffness and swelling don't improve after adequate thyroid treatment, check with your doctor.
