Can you have both a thyroid disorder and an underactive thyroid?

Yes, a thyroid disorder can include an underactive thyroid, also known as hypothyroidism. However, it is important to note that not all thyroid disorders involve an underactive thyroid.

The thyroid gland is a small butterfly-shaped gland located in the neck that produces hormones that regulate various bodily functions, such as metabolism, heart rate, and body temperature. There are two main types of thyroid disorders: hypothyroidism and hyperthyroidism.

Hypothyroidism occurs when the thyroid gland does not produce enough thyroid hormone. This can happen due to a variety of reasons, including autoimmune disorders (such as Hashimoto's thyroiditis), radiation therapy, surgery to remove the thyroid gland, or iodine deficiency. Symptoms of hypothyroidism can include fatigue, weight gain, constipation, dry skin, hair loss, and depression.

Hyperthyroidism, on the other hand, occurs when the thyroid gland produces too much thyroid hormone. This can be caused by conditions such as Graves' disease or a toxic nodule. Symptoms of hyperthyroidism can include weight loss, rapid heartbeat, tremors, anxiety, and sweating.

It is also possible to have other types of thyroid disorders, such as thyroid nodules or thyroid cancer. These conditions may or may not affect the production of thyroid hormone.

In summary, while hypothyroidism is a type of thyroid disorder that involves an underactive thyroid, there are other types of thyroid disorders that can affect the thyroid gland in different ways. It is important to consult with a healthcare professional if you suspect you have a thyroid disorder, as early diagnosis and treatment can help manage symptoms and prevent complications.
