What are the symptoms of low thyroid hormone?

Thyroid disease is directly related to the health of the body. Although there is no visible difference in a healthy thyroid gland at ordinary times, once the thyroid gland becomes diseased, it will obviously affect the whole body. The thyroid gland secretes thyroid hormones to control the balance in the body. If a disease occurs, the balance of hormone secretion will be disrupted. For example, low thyroid hormone is the most common example. So, what are the symptoms of low thyroid hormone?
