Questions about Hypothyroidism
Is levothyroxine approved for TSH suppression in hypothyroidism patients?
Levothyroxine is FDA-approved for TSH suppression only as an adjunct to surgery and radioiodine therapy for well-differentiated thyroid cancer, not for benign thyroid nodules or general hypothyroidism.
Full answer →What TSH cutoff values are used for preterm infants with hypothyroidism?
TSH cutoff values for preterm infants vary by gestational age, birth weight, and postnatal age; a 2024 study suggests a 97.5th percentile cutoff around 7.38 μIU/mL in the third postnatal week, while older studies use cutoffs like 6 mU/L.
Full answer →Does having hypothyroidism increase the risk of chronic kidney disease?
Yes, hypothyroidism is associated with a higher prevalence of chronic kidney disease, but the evidence on causing new CKD is less clear.
Full answer →Can levothyroxine tablets treat primary and secondary hypothyroidism?
Yes, levothyroxine tablets are FDA-approved to treat both primary and secondary hypothyroidism as replacement therapy.
