甲狀腺機能低下症

Also known as underactive thyroid, low thyroid, hypothyreosis, thyroid insufficiency

Hypothyroidism is an endocrine disease in which the thyroid gland does not produce enough thyroid hormones. It can cause a number of symptoms, such as poor ability to tolerate cold, extreme fatigue, muscle aches, constipation, slow heart rate, depression, and weight gain. Occasionally, there may be swelling of the front part of the neck due to goiter. Untreated cases of hypothyroidism during pregnancy can lead to delays in growth and intellectual development in the baby or congenital iodine deficiency syndrome.

AI overview

Hypothyroidism occurs when the thyroid gland fails to produce enough thyroid hormones, leading to symptoms like fatigue, cold intolerance, muscle aches, constipation, and weight gain. It matters because left untreated—especially during pregnancy—it can cause serious complications including goiter (neck swelling) and developmental delays in infants.
