Published: Apr 03, 2024
Being aware of the risk factors for subclinical hyperthyroidism can help you take preventive measures. Discover if you fall into the high-risk category and what you can do about it.
Contents
Common Risk Factors
Subclinical hyperthyroidism is more prevalent in certain populations, particularly older adults over 55 years. Women and smokers are also at increased risk, as well as those living in regions with mild to moderate iodine deficiency. Understanding these risk factors can aid in early detection and prevention.
Thyroid Hormone Therapy and Its Risks
Excessive thyroid hormone therapy is a significant risk factor for subclinical hyperthyroidism. Patients undergoing treatment for hypothyroidism or thyroid cancer are often at risk due to intentional TSH suppression. It's crucial to monitor thyroid hormone levels regularly to avoid unintended subclinical hyperthyroidism.

The Impact of Iodine
Iodine intake plays a crucial role in thyroid health. Areas with mild to moderate iodine deficiency tend to have higher rates of subclinical hyperthyroidism. Additionally, exposure to iodine-containing medications and supplements can affect thyroid function, highlighting the importance of balanced iodine consumption.
