While hyperthyroidism (as with Graves' disease) is a concern, so is hypothyroidism. There's some evidence of a higher risk of pregnancy loss, and increased risk of gestational hypertension (high blood pressure) andpreeclampsia(hypertension with high protein levels in urine), which can lead to pr...
TSH levels higher than 4.5 mU/L usually indicate an underactive thyroid (hypothyroidism), and low TSH levels—below 0.4 mU/L—indicate an overactive thyroid (hyperthyroidism).1 However, there are exceptions to these interpretations and variations as to what a "normal" TSH level is. This is be...
TSH levels below 0.003 mIU/L are considered abnormal and may require medical evaluation. A low TSH level can indicate an overactive thyroid gland (hyperthyroidism), which can cause symptoms such as weight loss, increased heart rate, and anxiety. Hyperthyroidism is often treated with medication or...
In a 51-year-old man with hyperthyroidism, elevated plasma TSH levels, and evidence of pituitary tumor, plasma TSH levels decreased from a mean basal value of 11 muU/ml to 6 mu/u/ml during the infusion of 200 mug of somatostatin in 60 min. Thyrotropin releasing factor failed to increase...
If hyperthyroidism coexists with non-suppressed TSH levels, a TSH-producing hypophyseal adenoma should be considered in the differential diagnosis despite its rarity. Octreotide administration is an effective and safe treatment and is the method of choice, especially when there are contraindications to ...
To present a new case of central hyperthyroidism caused by thyrotropin (TSH)-producing adenoma. Design. Case report. Setting. Departments of Internal Medicine, Diagnostic Radiology and Biochemistry, University of the Orange Free State, Bloemfontein. Subject and outcome measures. A 36-year-old woman ...
If the TSH level remains persistently low, usually in the presence of high thyroid hormone (T3 and/or T4) levels, the most common reason for hyperthyroidism isGraves disease, in which there are autoantibodies — measurable in the blood — that can stimulate the thyroid gland in the neck to ...
A TSH test is done to find out if your thyroid gland is working the way it should. It can tell you if your thyroid gland is overactive (hyperthyroidism) or underactive (hypothyroidism). This test can also detect a thyroid disorder before you have any symptoms. If untreated, a thyroid dis...
Inappropriate hypersecretion of TSH was investigated in a 25 year old man whose hyperthyroidism had relapsed 4 years after subtotal thyroidectomy. Serum TSH levels were further increased by both TRH and metoclopramide and were partially suppressed by triiodothyronine (120 micrograms/day). The serum alp...
Selenium supplementation for patients with Graves' hyperthyroidism (the GRASS trial): study protocol for a randomized controlled trial Background Graves??? hyperthyroidism is an autoimmune disease causing hyperfunction of the thyroid gland. The concentration of selenium is high in the thyr... T Watt...
