The thyroid is like a speed control or accelerator for the body. An overactive thyroid can leave a person feeling 'revved up', even when they should be getting ready to sleep at bedtime. An underactive thyroid slows a person down, and may cause symptoms of depression, fatigue, and weight gain. Thyroid conditions are relatively common, and can be treated.
When the thyroid gland does not produce enough hormone, the body uses energy at a slower pace than it should. This condition, underactive thyroid, is called hypothyroidism. Some of these symptoms -- fatigue, irritability, weight changes, and sleep problems -- are symptoms that may also indicate depression. Your doctor may order blood tests to determine levels of certain hormones, including: 1  thyroid stimulating hormone (TSH, which is released by the pituitary gland)  triiodothyronine (T3)
