Transient Hypothyroidism: Causes & Reasons

Possible Causes for Transient Hypothyroidism

Initial hyperthyroidism is common, sometimes followed by a transient period of hypothyroidism. Diagnosis is clinical and with thyroid function tests. [merckmanuals.com]

She was at first thyrotoxic, then transiently hypothyroid, and finally became euthyroid. [ncbi.nlm.nih.gov]

After several weeks, the thyroid is depleted of T4 and T3 stores, and transient hypothyroidism develops accompanied by a decrease in free T4 and T3, a rise in TSH, and recovery [merckmanuals.com]

Hashimoto Thyroiditis

Most patients go through a transient hyperthyroid phase, followed by a longer hypothyroid phase; most, but not all, recover spontaneously. [msdmanuals.com]

The thyrotoxicosis is usually mild to moderate and lasts for 1–4 weeks, followed by euthyroidism and transient hypothyroidism (,4). [pubs.rsna.org]

hypothyroidism due to depleted thyroid hormone stores but usually eventual recovery to the euthyroid state (as noted for painful subacute thyroiditis). [msdmanuals.com]

Thyroiditis

Initial hyperthyroidism is common, sometimes followed by a transient period of hypothyroidism. Diagnosis is clinical and with thyroid function tests. [msdmanuals.com]

Patients are initially hyperthyroid, with low TSH and elevated free T 4 ; they sometimes then become transiently hypothyroid, with high TSH and low free T 4. [merckmanuals.com]

In addition to TBG deficiency transient, secondary hypothyroidism occurred in approximately 40–50% of all patients treated with L-asparaginase. [link.springer.com]

Silent Thyroiditis

The patients were divided into 2 major groups: I) those who developed transient hypothyroidism and II) those who did not. [ncbi.nlm.nih.gov]

The thyrotoxic state spontaneously resolves in 2 to 12 weeks at which time the patient either returns to a euthyroid state or passes through a transient hypothyroid phase. [ncbi.nlm.nih.gov]

Of these, hyperthyroidism resolved spontaneously in 39 patients (76%), in whom transient hypothyroidism developed with substantial frequency. [ncbi.nlm.nih.gov]

Most of these women develop transient hypothyroidism and thyroid function usually returns to normal. [ncbi.nlm.nih.gov]
