There is no clinical statement that hypothyroid patients have a survival period of only 5-10 years, because hypothyroidism is curable. Patients with hypothyroidism can be treated with medications such as levothyroxine sodium tablets to maintain thyroid function at normal levels and their life expectancy will not be affected. Patients with hypothyroidism may have symptoms such as slowed thinking activity, fear of cold, slowed heart rate, weight gain, elevated blood lipids, edema, etc. Female patients may suffer from menstrual disorders, and in severe cases, plasma cavity effusion, such as pericardial effusion, mucus edema, coma, etc. Hypothyroidism symptoms need to be seen immediately after discovery, and symptomatic treatment should be followed by hypothyroidism medication to maintain thyroid function at normal levels. Most hypothyroid patients are lifelong hypothyroid, so they need to take medication for life to maintain normal thyroid function, but a small percentage of patients can be cured by treatment. If a patient has recently developed the above symptoms with no obvious cause, it is recommended to visit the endocrinology department as a priority to improve thyroid function tests. If the patient has been diagnosed, he or she should insist on taking medication to improve the symptoms, which usually will not affect the patient’s normal life and work. Female patients can also adjust the dosage and usage of medication under the guidance of the doctor before preparing for pregnancy or becoming pregnant.
