Can you have a normal thyroid ultrasound result but still hypothyroidism?

Yes, it is possible to have a normal thyroid ultrasound result but still have hypothyroidism.

Hypothyroidism is a condition in which the thyroid gland does not produce enough thyroid hormone. This can be caused by a variety of factors, including autoimmune disorders, iodine deficiency, and certain medications.

A thyroid ultrasound is a imaging test that can be used to evaluate the size, shape, and structure of the thyroid gland. It can also be used to identify any abnormalities in the thyroid gland, such as nodules or cysts.

In some cases, a person may have a normal thyroid ultrasound result but still have hypothyroidism. This may be due to the fact that the ultrasound is not able to detect all types of thyroid abnormalities. For example, a thyroid ultrasound may not be able to detect small nodules or cysts, or abnormalities that are located deep within the thyroid gland.

In addition, a thyroid ultrasound may not be able to detect functional abnormalities of the thyroid gland. For example, a person may have a normal thyroid ultrasound result but still have hypothyroidism if they have a problem with the way their thyroid gland produces or uses thyroid hormone.

If you are concerned about your thyroid health, it is important to see your doctor even if you have a normal thyroid ultrasound result. Your doctor may order additional tests, such as thyroid function tests, to evaluate your thyroid function and determine if you have hypothyroidism.
