Understanding Subclinical Hypothyroidism
Subclinical hypothyroidism is a condition where your thyroid doesn't produce enough hormones, but it may not show obvious symptoms. It's diagnosed by elevated levels of thyroid-stimulating hormone (TSH) while having normal thyroid hormone levels. Many people with this condition might not realize they have it since symptoms can be vague or absent.
Who Is at Risk?
This condition is more common as people age and is more frequently seen in women than men. Studies also show that it is less prevalent in Black people compared to White people. Factors such as autoimmune diseases, previous thyroid surgeries, and certain medications can increase the likelihood of developing subclinical hypothyroidism.

Potential Health Impacts
Subclinical hypothyroidism can progress to overt hypothyroidism, which has more noticeable symptoms and requires treatment. It may also be linked to an increased risk of heart problems and other health issues. However, not everyone with subclinical hypothyroidism will experience these complications.
