How long after getting proper dose of synthroid (thyroxine) should I begin to feel less symptomatic? last tsh was 23.

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 free T4 is high 19.30 pmol/l and my TSH is also high 4.530 mlu/l. What does this mean?

My free T4 is high 19.30 pmol/l and my TSH is also high 4.530 mlu/l.  What does this mean?

Few possibilities: These labs seem at odds, with TSH suggesting overactive thyroid and ft4 underactive thyroid. Free T4 tests can be inaccurate in some people who have interfering substances present. Another possibility is a tumor in the pituitary secreting too much TSH resulting in thyroid overactivity, and high thyroid hormone levels. This is quite rare, however. Your doctor can help sort this out. ...Read more

Excessive hunger in the last few weeks. Thyroid TSH has been anywhere from .2 to 8 in the last four months. Why so hungry no matter how much i eat?

Excessive hunger in the last few weeks. Thyroid TSH has been anywhere from .2 to 8 in the last four months. Why so hungry no matter how much i eat?

A few reasons: Make sure your thyroid is in balance. Some believe that high carb/sugar content diets actually increase hunger, and that foods with more protein&fat content decrease hunger. Something else you might try is to take an increase in fiber content and filling your stomach with water to stimulate your sense of fullness. This is a constant struggle for many with many opinions. Search for which helps you. ...Read more

..what does a TSH of 4.84 mean?

Mildly high: A TSH of 4.84 means that your pituitary gland is not completely happy with your thyroid level, and is trying to get your thyroid to produce more thyroid hormone. Considering your history of RA, you may also have Hashimoto's thyroiditis, which can eventually cause your thyroid to fail. You should have a free T4 level, though it is likely to still be normal. Eventually you may need thyroid hormone ...Read more

What does it mean to have a TSH of 4.25?

Borderline: There is slight controversy about normal levels. Most doctors consider a level between 0.5 and 5.0 to be normal. Others prefer it to be below 2.5. Your level could be considered early sign of thyroid deficiency. Please discuss it with your doctor and look at the results of free t4.

Tsh .55,t-3 88, t-4 10 Is this optimal?

Tsh .55,t-3 88,  t-4 10 Is this optimal?

No problem: Hi. Those thyroid function tests are normal. However, a total T4 has only a fraction of the value of a free T4, so you might want to suggest to your old-timer doc to stop ordering total T4 and get a free T4. But it wouldn't change anything. You're toward the hyper end of normal, and that's OK. Are you taking l-thyroxine? Good luck! ...Read more
