Final answer:
A pregnant patient with hypothyroidism needs to take medication to ensure the proper development of the fetus, especially the brain, and to maintain her own health. Thyroid hormones regulate metabolism and other vital functions, and their levels must be carefully managed during pregnancy.
Step-by-step explanation:
When a pregnant patient is diagnosed with hypothyroidism, it is crucial that she takes medication for this condition because thyroid hormones are vital for the development of the fetus, particularly for brain maturation. Insufficient levels of these hormones may lead to serious consequences such as permanent deficits in cognitive abilities and possible deafness in the unborn child. In adults, hypothyroidism can lead to symptoms such as weight gain, tiredness, and cold intolerance. It is primarily treated with thyroid hormone replacement therapy, which might be needed for life depending on the cause of the disorder. However, in some cases, such as when hypothyroidism is pregnancy-induced, medication may not be required after childbirth once hormone levels return to normal.
Thyroid hormones, specifically thyroxine (T4) and triiodothyronine (T3), regulate metabolic rate and other vital body functions. Therefore, during pregnancy, adequate levels need to be maintained with medication to ensure the health of the mother and proper fetal development. Treatment must be carefully monitored to ensure proper dosing of the replacement hormones, as both underproduction and overproduction of thyroid hormones can cause complications.
