Can Medication Shrink Thyroid Nodules
Usually not: In the distant past, thyroid hormone was used to 'shrink' nodules. More recent studies with ultrasound monitoring has shown that most nodules do not shrink with thyroid hormone treatment. Because thyroid cancer is the fastest increasing cancer in women, it is important to follow most thyroid nodules with ultrasound. With hashimoto's thyroiditis, there can be false or pseudonodules. ...Read moreSee 1 more doctor answer
Nodules hypothyroid: The most common cause of low thyroid is autoimmune Hashimoto's thyroiditis. The lumps in the thyroid can and do exist with the Hashimoto's but don't cause the underlying problem. It is possible that a thyroid gland can become so full of thyroid nodules that it becomes unfunctional, but this is unusual. ...Read moreSee 1 more doctor answer
To some extent: If a goiter is due to primary hypothyroidism then levothyroxine allows TSH to come down thereby removing one source of goiter. However, patients with hashimoto's also have lymphocytic infiltration of the gland which contributes to goiter development also. That takes time to go down. We see this in patients with nl thyroid function also. Grave's antibodies stimulate thyroid growth mimicking tsh. ...Read more
In some cases: Talk to your doctor before doing this and come up with a plan to monitor you and make sure that your hypothyroidism is still subclinical, meaning that it is causing no ill effects. Many times, though, subclinical hypothyroidism will progress to overt hypothyroidism, so you and your doctor will need to monitor this for many years. ...Read more
Need further eval: The low TSH needs to be addressed as it can cause problems for you. In the presence of thyroid nodules, you will need a thyroid uptake and scan to make sure the nodules are not producing too much thyroid hormones. Treatment then would be antithyroid drugs, radioactive iodine, or surgery. You should not be doing nothing with a low tsh. ...Read moreSee 1 more doctor answer
Will thyroid hormones or antithyroid medications interfere with a tc99m pertechnetate thyroid scan?
Not usually: Technetium is usually trapped by thyroid gland and used to determine in young children and infants the configuration of thyroid gland, hypoplasia, absence, or increased size or hyperplasia, or abnormal location. Radioactive iodine is used in older patients for determine function of thyroid gland, increased function or hyperthyroiidism or decreased function, hypothyroidism. ...Read moreSee 2 more doctor answers
Usually none.: If the follicular adenoma is causing hyperthyroidism (too much thyroid hormone), treatment is usually either surgery or radioactive iodine to kill the tumor. Thyroid-blocking meds such as Methimazole or ptu (propylthiouracil) may be used to lower thyroid levels before one of these other treatments. If thyroid levels are normal, no treatment is needed, but surgery is sometimes done to make sure the tumor is benign. ...Read moreSee 1 more doctor answer
Maybe: If you treat with levothyroxine, lowering the tsh, the goiter may shrink. But often it does not, at least not much. There is also a risk of inducing hyperthyroidism. If there is a cyst, aspiration of the cyst may shrink the gland, but the fluid in the cyst often comes back. If the goiter is big and compressing airway or esophagus, surgery may be needed. ...Read more
Have thyroid goiter and inflammation. No nodules. Feel lump in throat. On Synthroid (thyroxine) 75mcg for hashimotos. Can you have thyroid cancer with no nodules?
Some are caused: By iodine deficiency, which is a reason for iodinized table salt...Those lacking seafood in the midwest and near west used to be so afflicted. Taking exogenous thyroid hormone (thyrolar, synthroid) may turn off TSH stimulation and reduce/diminish growth, but that is treatment rather than prevention. ...Read moreSee 1 more doctor answer
