How Does Thyroxine Inhibit Tsh
Depends: Hi. Those labs could reflect transitioning phases of a subacute thyroiditis from hyper- to hypothyroidism. You could also see those labs if you are taking Cytomel (T3, liothyronine); I see that you are. The most likely in your case is that your T3 is suppressing your TSH, and that drops endogenous T4 production by withdrawing endogenous stimulation to your thyroid gland. Why are you on T3? ...Read moreSee 1 more doctor answer
Your endocrinologist: You should consult your endocrinologist and let her/him suggest the dose, depending on the current dose, any symptoms and any changes in your TSH level. ...Read more
Depends: Most old reference ranges allow TSH upper limits up to 5.0. neew guidelines say thee upper limit should be no higher than 2.5. o by the new norms your TSH level would be considered abnormal , and medication adjustment may be needed. i personally use the old norms still, so i would not change anything at this point. ...Read moreSee 1 more doctor answer
Thyroid misjudged: Thyroid is the most poorly managed endocrine gland today. Synthetic thyroid (synthroid) cannot convert to active thyroid if your liver is not healthy. Thyroid patients never feel right because a pill never fixes this. You have to completely revamp your lifestyle to get the liver/gut to convert the thyroid medication. So the following need to be checked: TSH,T4 and T3 (liothyronine) and also antibodies. ...Read moreSee 1 more doctor answer
Is it true that during fall and winters, TSH rises again. Do I need a higher dose of Synthroid (thyroxine) from Oct?
Unlikely: I have never heard of this occurring and have not noticed it in my patients despite 30+ years of practicing. If your TSH level has been fluctuating, the most likely cause is that you should be taking a brand name form of thyroid hormone (Synthroid, Levoxyl, (thyroxine) Unithroid, etc), take it on an empty stomach and wait 60 min before eating. No vitamins or supplements until at least 4 hrs later. ...Read more
How long after getting proper dose of synthroid (thyroxine) should I begin to feel less symptomatic? last tsh was 23.
Usually on the order: Of two to three weeks. But I should warn you there are some patients that some neuromuscular and psychiatric symptoms can take months to resolve. It's also possible that some symptoms thought to be related to hypothroidism like fatigue or weight, may in fact be related to other factors/issues, even when the hypothyroidism is corrected. ...Read more
My TSH is 94.47, I am 58, i did not realize that anything was wrong, Synthroid (thyroxine) of 75 mcg making me feel worse.
Hypothyroid: The high TSH looks like hypothyroidism. You need to get your thyroid levels normal. You may have been hypo for a long time, and have become used to it. There may be some temporary symptoms while your blood levels change. You may eventually need more than 75 mcg/day to get thyroid normal. ...Read more
I starded to take thyroxine few weeks ago, i m at 50 by day but see no benefit. Tsh was 3.2 before beginning, can I slowly stop thyroxine ?
Discuss this with ur: Dr. U usually don't expect any significant body function change with (low) dose thyroid replacement in few weeks.It may take 2-3 months to notice a difference in ur energy/metabolism. If u r expecting ur libido to improve with thyroid hormone therapy, don't count on it. The testosterone meds ur taking should do it. Take care! http://www.M.Webmd.Com/a-to-z-guides/tc/hypothyroidism-topic-overview. ...Read moreSee 1 more doctor answer
Three weeks ago TSH was .007 and Synthroid (thyroxine) was lowered. Tsh now .02 should it be lowered again? I am having terrible symptoms..
Yes, your synthroid (thyroxine): Dose should be adjusted until TSH is in normal range, high normal if you need to suppress thyroid function for cancer. Because half life of thyroid hormone is two weeks, any TSH measurements and dose adjustments should be done gradually. Consult with your doctor for specific advice. ...Read more
