Overview
Endemic goiter results from chronic iodine deficiency, leading to hypothyroidism and enlargement of the thyroid gland. This condition is particularly concerning in populations with inadequate iodine intake, such as pregnant women, where it can affect maternal and fetal health 1.Diagnosis
Measure serum thyrotropin (TSH) and free thyroxine (FT4) levels to assess thyroid function.
Assess urinary iodine concentration (UIC) to evaluate iodine status; <150 μg/L indicates inadequate intake 1.
Evaluate serum thyroglobulin (Tg) concentrations, which may be elevated in iodine deficiency 1.
Screen for anti-thyroid peroxidase (anti-TPO) antibodies to rule out autoimmune thyroid disease 1.Management
Implement iodine supplementation to correct deficiency; specific dosing not detailed in the abstract 1.
Monitor thyroid function tests (TSH, FT4) regularly to adjust iodine supplementation as needed 1.
Consider dietary counseling to increase iodine-rich foods intake 1.Special Populations
Pregnancy: Pregnant women in iodine-deficient areas exhibit elevated thyroglobulin levels and inadequate iodine intake, necessitating close monitoring and supplementation 1.Key Recommendations
Screen pregnant women for iodine deficiency using urinary iodine concentration (UIC) and serum thyroglobulin levels 1 (Evidence: Moderate).
Initiate iodine supplementation in pregnant women with UIC <150 μg/L to improve maternal and fetal thyroid health 1 (Evidence: Moderate).
Regularly monitor thyroid function tests in pregnant women with iodine deficiency to guide management 1 (Evidence: Moderate).References
