Secondary hyperthyroidism is characterized by elevated levels of TSH, freeT4 and/or free T3 levels. If the free T4 level is normal but symptoms of hyperthyroidism are present along with a suppressed TSH, T3 toxicosis should be considered and a serum free T3 level should be determined if not ordered initially.
The symptoms for low thyroid function (hypothyroidism) are varied and mostly mimic symptoms of perimenopause. Common symptoms of hypothyroidism are weight gain, low basal body temperature, brittle fingernails, cold sensitivity and cold hands and/or feet.erimenopause symptoms versus hypothyroidism symptoms. Hypothyroidism, perimenopause / menopause and weight gain-both hypothyroidism and perimenopause / menopause are associated with weight gain. Too little thyroid will slow down the metabolism, and in many cases, lead to unintended weight gain.
