Symptoms of hypothyroidism include fatigue, high cholesterol, weight gain, memory loss and depression, Mayo Clinic states. The condition primarily affects women, mostly over the age of 60. Autoimmune disease, recent pregnancy and radiation treatment are additional risk factors. Some medications, including lithium, can contribute to the condition.

Hypothyroidism, when untreated, can contribute to a wide variety of health problems, including heart disease, nerve damage, infertility, birth defects and mental health issues, Mayo Clinic says. It is important to have the thyroid checked if symptoms are present.
