Hypothyroidism, Hypertension and Breast Cancer: Scientific Insights ACRCI - Iris Publishers
Subclinical hypothyroidism is an early stage of hypothyroidism and is usually manifested as elevated thyrotropin-stimulating hormone (TSH) and normal free thyroxine (T4) levels. In such cases, clinical symptoms are usually not manifested although some cases may have minor/subtle symptoms of hypothyroidism and may have mild abnormalities of serum lipoproteins and cardiac function. This condition may resolve, remain unchanged, or develop into overt hypothyroidism within few years, with low free T4levels as well as a raised TSH level. The likelihood that this will happen increases with greater TSH elevations and detectable antithyroid antibodies [1-5].
