Quick Answer. Symptoms of low thyroid-stimulating hormone, or TSH, levels due to hyperthyroidism include rapid heartbeat, sudden weight loss, nervousness, tremors and increased appetite, notes Mayo Clinic. Some symptoms of low TSH levels due to secondary hypothyroidism are fatigue, depression, weight gain and cold intolerance, states UCLA Endocrine Surgery.
