Hypothyroidism visits should generally be made to an endocrinologist for appropriate treatment as prescribed by the doctor. Hypothyroidism, or hypothyroidism, is a generalized low metabolic syndrome caused by thyroid hormone resistance or hypothyroid hormonemia due to various reasons, such as autoimmune damage, thyroid destruction, iodine excess or deficiency, pituitary gland or hypothalamus lesions, etc. Hypothyroidism belongs to the category of endocrine diseases, and therefore needs to be seen by endocrinologists. Hypothyroidism generally requires lifelong thyroid hormone replacement therapy, i.e., taking drugs such as levothyroxine to maintain the serum thyroid stimulating hormone (TSH), total thyroxine (TT4), and free thyroxine (FT4) at normal levels, so as to eliminate the symptoms and signs of hypothyroidism. Patients with hypothyroidism should consult a doctor in time and have a reasonable treatment plan formulated by a professional doctor, and avoid blindly using medication on their own to avoid affecting their condition.
