You can experience symptoms of hypothyroidism with normal TSH levels. Learn more about when and how this can occur.
A case of a 66-year-old woman with clinical myxoedema and positive thyroid autoantibodies is reported. An unusual feature was the discrepancy between normal total and free T, and T. levels and high TSH values, in the absence of a pituitary adenoma. This clinical picture can be explained by...

If you have symptoms of hypothyroidism, your doctor will order blood tests to check hormone levels. These may include: Thyroid-stimulating hormone (TSH) T4 (thyroxine) Lower-than-normal T4 levels usually mean you have hypothyroidism. However, some people may have increased TSH levels while having...

All were considered to have hypothalamic hypothyroidism on the basis of low thyroxine (T 4) concentrations, inappropriately low thyrotropin (TSH) levels, with a normal TSH response to thyrotropin-releasing hormone (TRH, 500 μg intravenously) in three, and absence of a pituitary lesion. ...
Subclinical hypothyroidism is defined as having normal serum levels of the thyroid hormones thyroxine (T4) and triiodothyronine (T3), in conjunction with an elevated serum TSH level. From: Pharmacology and Therapeutics, 2009 About this pageAdd to MendeleySet alert Also in subject areas: M...
Based on their initial serum-free thyroxine (fT4) and thyroid-stimulating hormone (TSH) levels, they were classified into control, subclinical hypothyroidism (TSH >4.2 mIU/L, normal fT4), and overt hypothyroidism (TSH >4.2 mIU/L, fT4 <0.97 ng/dL) groups. NAFLD was diagnosed on the basis ...
In people with short-term hypothyroidism caused by certain types of thyroid inflammation or viral thyroid infections, levels of thyroid hormones often return to normal after several months. In other people with hypothyroidism, the disorder is a lifelong problem....
However, our sample is comparable to similar questionnaire studies on PROMs in treated hypothyroidism, which include data on non-responders according to age, sex ratio, cause of hypothyroidism, percentage normal TSH levels, and disease duration. Moreover, comparison of responders to non-responders in...
