Symptoms of high thyroid stimulating hormone need to be combined with other laboratory tests, if only high thyroid stimulating hormone is generally asymptomatic. 1. Only high thyroid stimulating hormone, T3, T4 is normal, for subclinical hypothyroidism, generally asymptomatic, a few patients may appear mild fatigue and other symptoms. 2. Increased thyroid stimulating hormone with decreased T3 and T4 may show symptoms of hypothyroidism, such as chills, slow heart rate, fatigue, constipation, weight gain, facial edema, and unresponsiveness. 3. Increased thyroid stimulating hormone with increased T3 and T4 can show symptoms of hyperthyroidism, such as fever, panic, insomnia, polyphagia, weight loss, etc. This situation is mostly seen in central hyperthyroidism, such as pituitary TSH tumor. High thyroid stimulating hormone needs timely medical treatment under the guidance of a doctor.
