A sluggish expression is one of the symptoms of hypothyroidism. The full name of hypothyroidism is hypothyroidism, which means that the thyroid gland cannot produce enough thyroid hormone to meet the normal needs of the body due to various reasons. The symptoms of hypothyroidism include fear of cold, decreased sweating, dry skin, sluggish expression, slowed heart rate, loss of appetite, dry stools, and fatigue. The prevalence of sluggish clinical expression is about 1%, more common in women than men, and increases with age. In severe cases, mucinous edema can be caused, and in more severe cases, mucinous edema coma can be caused. If pathological hyperplasia and hypertrophy of adenoids occur due to repeated stimulation of inflammation, it will affect the growth and development of children. As children’s nasopharynx is relatively small, when adenoid hypertrophy, due to nasal congestion affects breathing and mouth open breathing, long-term mouth breathing, airflow impact on the hard palate will make the hard palate deformation, high arch, over time, facial development will be deformed, the upper lip short thick cocking, lower jaw sagging, nasolabial groove disappeared, hard palate high arch, teeth alignment is not neat, upper incisors protrude, poor bite, nasal septum flat curvature, etc., facial muscles The facial muscles are not easy to move, lack of expression, and look like a piggyback or ugly duckling, which is called “adenoid face” in medical science. The recommended treatment for adenoid hypertrophy is surgery or a combination of Chinese and Western medicine. If the child is older (over five years old) and has heavy symptoms, especially respiratory symptoms and snoring, it is very unlikely that adenoid hypertrophy will heal on its own, so the sooner surgery is performed, the better, because conservative treatment is slow and the symptoms themselves have a great impact on the child’s development.
