KnowraCentral hypothyroidismLinked fromLinked fromThe 9 pages that link to Central hypothyroidism, each with the reason it gives.All 9Broader topic 4Related 2Compared with 3HypothyroidismBroader topic: This form disrupts regulation upstream, so thyroid-stimulating hormone may not rise appropriately.Thyroid-stimulating hormoneCompared with: TSH may be low or inappropriately normal, unlike the usual rise in primary thyroid failure.Thyroid function testsBroader topic: It shows why a normal or low TSH cannot always exclude hypothyroidism.Hypothalamic–pituitary–thyroid axisBroader topic: It demonstrates how upstream axis failure can mimic thyroid-gland disease.Hypothalamic-pituitary axisRelated: It demonstrates how upstream failure can impair a peripheral gland despite an intact thyroid.Hashimoto's thyroiditisCompared with: It contrasts with Hashimoto's, where the primary defect lies in the thyroid gland itself.HypopituitarismBroader topic: Low pituitary thyrotropin can reduce thyroid hormone despite an otherwise functional thyroid gland.Thyrotropin-releasing hormoneRelated: Impaired hypothalamic TRH signaling can contribute to deficient thyrotropin drive.ThyroidCompared with: It contrasts with primary thyroid failure because the defect lies upstream of the gland.
