The human thyroid. (Redrawn with permission from Ganong WF. Review of Medical Physiology. 22nd ed. McGraw-Hill; 2005.)


Thyroid cell. Left: normal pattern. Right: after TSH stimulation. The arrows on the right show the secretion of thyroglobulin into the colloid. On the right, endocytosis of the colloid and merging of a colloid-containing vacuole with a lysosome are also shown. The cell rests on a capillary with gaps (fenestrations) in the endothelial wall.

A 46-year-old female has been referred to PT for sarcopenia and fatigue. She is a high school teacher, and describes barely being able to get through a day. She complains of generalized achiness and has been treated for depression over the past 3 months but has not seen any improvement. Up until about a year ago she was an avid walker, and walked with colleagues at least three to four times a week. Her history indicates weight gain without change in diet. During postural assessment, the PT notes what appears to be a swelling in her neck, which she attributes to the weight gain. There is a nontender palpable mass in her neck. When tested, her muscle performance demonstrated extremity and core weakness, with easy fatigability.



  • Autoimmune disease

  • Thyroid gland is gradually destroyed

  • Results in hypothyroidism

  • Enlargement of the thyroid

Essentials of Diagnosis

  • Thyroid gland becomes lobulated

  • Decreased activity tolerance

  • Sensitivity to cold
