“Hypothyroidism happens when the thyroid gland doesn’t make enough thyroid hormone. This condition also is called underactive thyroid. Hypothyroidism may not cause noticeable symptoms in its early stages. Over time, hypothyroidism that isn’t treated can lead to other health problems, such as high cholesterol and heart problems.”

MAYO CLINIC (Hypothyroidism (underactive thyroid) – Symptoms and causes – Mayo Clinic)
