Gestational subclinical hypothyroidism...The prevalence of gestational subclinical hypothyroidism has been increasing with years, and it has become one of the common diseases happened to women during pregnancy in China. Gestational subclinical hypothyroidism can not only increase the incidence of adverse pregnancy outcomes, but also have a negative impact on the development of the offspring. Therefore, it is necessary to make an early detection, diagnosis and treatment.展开更多
