What is the prevalence of Hypothyroidism?

Hypothyroidism is a common endocrine disorder characterized by an underactive thyroid gland, resulting in insufficient production of thyroid hormones. It affects individuals of all ages, but is more prevalent in women and older adults. The prevalence of hypothyroidism varies across different populations and geographical regions.

According to various studies and estimates, the global prevalence of hypothyroidism ranges from 1% to 2%. However, it is important to note that the prevalence may be higher in specific subgroups, such as individuals with certain autoimmune conditions like Hashimoto's thyroiditis.

In the United States, it is estimated that around 4.6% of the population aged 12 and older has hypothyroidism. This translates to approximately 11 million people. The prevalence tends to increase with age, with older adults being more affected.

Undiagnosed cases of hypothyroidism are also a concern. It is believed that a significant number of individuals may have the condition but remain undiagnosed due to mild or nonspecific symptoms. Regular thyroid function testing is crucial for accurate diagnosis and appropriate management.

Early detection and proper treatment of hypothyroidism are essential to prevent complications and improve quality of life. If you suspect you may have hypothyroidism, it is important to consult with a healthcare professional for evaluation and guidance.
