I take 75 Synthroid (thyroxine) after a thyroidectomy. Would an iodine supplement help? How would I know if I were iodine deficient?

Iodine not needed: The primary organ that uses iodine is the thyroid. If your thyroid is removed, then an iodine supplement will not be of use. In addition, there is a lot of iodine in a normal diet. It is very hard to become iodine deficient in all but a handful of remote regions of the world. Read more

How long after a thyroidectomy should one wait before beginning synthroid (thyroxine)?

How long after a thyroidectomy should one wait before beginning synthroid (thyroxine)?

Need path results.: Start it ASAP after surgery, as long as you won't have post-op radioiodine therapy (RAI) used for some thyroid cancers-- in which case start AFTER RAI.

Usually you don't know if you need RAI for sure until final pathology results come in about a week post-op. Some surgeons start Synthroid (thyroxine) right after surgery and stop if path determines need for RAI. Others will wait for path first, then Read more

How long can you live without thyroxine after a thyroidectomy? How long does it take to become unwell?

How long can you live without thyroxine after a thyroidectomy? How long does it take to become unwell?

Hypothyroidism: That is complex. A baby born without a thyroid can have life long severe consequences if treatment is delayed or discontinued. An elderly or compromised person might die because their body can't withstand the additional problem of hypothyroidism. If it is you, otherwise healthy, thyroid was removed you might go a while feeling hypothyroid before you were severely ill. Monitor! Take medicine! Read more

Total thyroidectomy more than a year ago due to hashimotos disease. How long could I live without taking my thyroxine 150mcg?

Does not add up: Hashimoto is not a reason for thyroidectomy. Why would you not not take replacement medication? You may live for a variable length of time but would not be healthy. Stay on the medication and do not change the dose without consulting your doctor. Read more

Having a total thyroidectomy. History hypo, multiple nodules, on Synthroid (thyroxine) 100mcg. Had horrible wt gain over yr. Will I likely gain lots of wt after?

No: You do not need a thyroid, you just need thyroid hormone in the correct dose to maintain a normal TSH level. If your thyroid level remains normal, it should not affect your weight. I assume that you are having a total thyroidectomy because you had a thyroid biopsy that was suspicious for thyroid cancer. If this is not the case, you should get a second opinion from an endocrinologist. Read more

I had total thyroidectomy but surgeon left a very small piece in. Do I still need synthroid (thyroxine). And if so would I go hyper?

I had total thyroidectomy but surgeon left a very small piece in. Do I still need synthroid (thyroxine). And if so would I go hyper?

Depends on amount: Small fragments are often left for various reasons. If half is left you have a good chance that is enough. Less remnant means higher likelihood of hypothyroidism. If your thyroid was removed for cancer, you should probably be made hyperthyroid to suppress your TSH and subsequently your thyroid and thyroid cancer from growing. Read more

Haven't had much appetite and had little nausea and lost a few lbs since total thyroidectomy 1 wk ago. Can this happen. On synthroid (thyroxine).?

Haven't had much appetite and had little nausea and lost a few lbs since total thyroidectomy 1 wk ago. Can this happen. On synthroid (thyroxine).?

Synthroid (thyroxine): Synthroid (thyroxine) could cause this; however, it is unlikely since you've only been taking it for a week -- with the exception of the nausea. The anesthesia used for surgery may have some effect. In addition, your body is healing from the surgery and the release of certain hormones may be involve in this as well. Other medication may also contribute (ie: post surgery antibiotics). Read more

Total thyroidectomy 2003 taking thyroxine 125mg daily. Had a prolactin blood test yesterday what does this show please?

Prolactin: Is a pituitary hormone that prepares the breast for nursing an infant. It can be increased in some pituitary tumors, some medications, hypothyroidism not on sufficient replacement, breast stimulation, other causes. Can't tell you the significance since I don't know your result. Check w/your doctor. Read more

If your thyroid: Level is normal, and your hair loss was due to thyroid problems, it will grow back -- but hair growth is very slow and can take months and months to return to normal. Make sure there are no other causes. Read more

Had partial thyroidectomy in '96. Since 2002 have continued to lose weight. Diagnosed with hypo, but I have all symptoms of hyper tried Synthroid but it sped up the weight loss and I never stop losing, adds to my severe insomnia. Once I stopped taking syn

It: It sounds like you have had a very complicated course since your thyroidectomy. Your symptoms really concern me (high cholesterol, anxiety, rapid pulse), and I would suggest that you should have a complete endocrinology evaluation, but you may also have other issues going on. You can't be both hypo- and hyper-thyroid, but there could be co-existing conditions. Please notify your doctor and have a complete evaluation of your symptoms. Read more

THYROID EXHAUSTION: You can expect not to feel yourself, particularly energy wise, until and after the supplement being used to replace your thyroid is enough and plenty, and has been in your system for several weeks. Every patient is different but it may take months before you start feeling yourself. Read more

I take cytomel (t3) 10mg daily with synthroid 50mg daily for a thyroidectomy in 2010. Does T3 (liothyronine) cause a increase in creatinine? Microabumin/creat is 59h

I take cytomel (t3) 10mg daily with synthroid 50mg daily for a thyroidectomy in 2010. Does T3 (liothyronine) cause a increase in creatinine? Microabumin/creat is 59h

No: Cytomel (liothyronine) is a synthetic form of triiodothyronine which is one of the hormones normally made in the thyroid. There is no evidence that it should affect renal function; this abnormality should be evaluated separately from your hypothyroidism. Read more

Partial thyroidectomy in 2006 for nodule, result was benign. Been on 100mcg Synthroid (thyroxine) but a new small nodule has appeared. Had ultrasound and told to not worry and come back in 1 yr. Do you agree?

Partial thyroidectomy in 2006 for nodule, result was benign. Been on 100mcg Synthroid (thyroxine) but a new small nodule has appeared. Had ultrasound and told to not worry and come back in 1 yr. Do you agree?

Yes: Nodules are common in the thyroid. As long as you have thyroid tissues, there is always a chance of a new nodule popping up. If the past surgery was benign, and the new nodule is small, you can follow it with regular ultrasound and act on it (biopsy) only if there are significant changes on the ultrasound. Read more

My mom had a full thyroidectomy. She is taking synthroid (thyroxine). Where is she getting T3 from if at all?

My mom had a full thyroidectomy. She is taking synthroid (thyroxine). Where is she getting T3 from if at all?

Converted from T4: The body has enzymes that convert the T4 to t3 (liothyronine). T3 (liothyronine) is the actual workhorse of the thyroid hormones and there is less of it in the body. Read more

I have TSH 4.910 High and T4 12.1 High - why are both high? I have had thyroidectomy and take synthroid (thyroxine).

I have TSH 4.910 High and T4 12.1 High - why are both high? I have had thyroidectomy and take synthroid (thyroxine).

Need more info: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, your TSH is borderline high, T4 may be normal especially if you are taking birth control pills. It would be prudent to discuss this with your doctor at the next visit.
