Hypothyroidism in women can be detected by laboratory tests, thyroid imaging, etc. Consultation with a doctor is recommended. 1. Laboratory tests: thyroid function tests, including free triiodothyronine, total triiodothyronine, thyroid stimulating hormone, total thyroid hormone and free thyroxine, etc. Thyroid antibody tests, such as thyroid peroxidase antibody and thyroglobulin antibody, etc., can help to clarify the cause of primary hypothyroidism. 2. Thyroid imaging: thyroid ultrasound can determine whether the thyroid gland is enlarged or not, because some patients with hypothyroidism can be accompanied by goiter. Other tests such as magnetic resonance and thyroid nuclear imaging can also be performed for differential diagnosis. In addition, hypothyroidism can be assessed by the presence of hypothyroidism symptoms such as fatigue, chills, bradycardia, dry skin, and decreased concentration, as well as a history of thyroid surgery, autoimmune diseases, and other related medical conditions or treatments. Women suspected of having hypothyroidism are advised to go to the hospital and ask the doctor to make a judgment.
