This condition may or may not require treatment, depending on the individual’s age, symptoms, and other risk factors. Subclinical...
Low estrogen impairs the thyroid gland's ability to make thyroid hormones. So, TSH rises to get the thyroid to produce more. High estrogen leads to increased thyroid hormone production and lower TSH. In menopause, estrogen levels are lower, which sometimes triggers thyroid disease.4 TSH Levels ...
Does high TSH cause weight gain? In one of the studies that had data for a single point in time, blood TSH levels were related to waist size and the ratio of waist to height sizes. For example, high blood TSH levels in this study (indicating a more underactive thyroid gland) were rela...

Serum TSH level in this study was not always measured at the same interval because of more frequent measurements in patients with high or low serum TSH levels and clinician preference. To avoid potential bias, we used ...
High levels of thyroxine and triiodothyronine occur due to abnormal thyroid function. Excessive amounts of thyroxine in the blood plasma decreases the production of TSH, leading to low TSH levels. Causes Low TSH is caused by conditions that increase thyroxine production such as Graves' disease, thy...
