Abstract:
Hypothyroid patients on stable long-term oral levothyroxine (T4) dosage are at risk of developing overt hypothyroidism after small bowel (SB) resection. This can happen despite equivalent peri-operative intravenous (IV) supplementation and resumption of preoperative oral T4 dosage when post-operative oral medication is tolerated. This situation is not specifically addressed in any of the major guidelines for T4 oral replacement in this setting and may be underrecognized, leading to diagnostic and management challenges.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
