Understanding Subclinical Hyperthyroidism
Subclinical hyperthyroidism refers to a condition where the thyroid gland is overactive but doesn’t show obvious symptoms, characterized by normal levels of thyroid hormones T4 and T3 and a low thyroid-stimulating hormone (TSH) level. This condition is often identified through routine blood tests rather than noticeable symptoms. Despite its subtlety, it can lead to serious health issues if left unchecked.
Who is at Risk?
Subclinical hyperthyroidism is more prevalent in older adults, particularly those over 55 years. Women, smokers, and individuals residing in areas with iodine deficiency also have a higher risk of developing this condition. The condition can be persistent or transient, with causes ranging from excessive thyroid hormone therapy to autonomously functioning thyroid adenomas.
Consequences You Should Know
Even without symptoms, subclinical hyperthyroidism can lead to complications like atrial fibrillation and reduced bone mineral density, especially in postmenopausal women. It can also progress to overt hyperthyroidism, increasing the risk of more severe health problems. Cardiovascular issues and bone health are particularly at risk, necessitating regular monitoring.
