Hypothyroidism is a condition in which your thyroid does not make enough of the thyroid hormone.
Some more common symptoms of hypothyroidism include the following:
Hypothyroidism occurs when the thyroid gland doesn't produce enough of the thyroxine hormone (T-4). Hypothyroidism may be the result of a number of conditions including autoimmune disease, inflammation, nutritional deficiencies such as iodine, selenium and zinc, Pituitary dysfunction, stress and elevated cortisol levels, and imbalanced hormones.
If left untreated, hypothyroidism can lead to myxedema, a condition that causes tissues to retain fluid with swelling under the eyes and around the heart and lungs. A myxedema coma may cause you to lose consciousness, experience trouble breathing, and can potentially lead to heart failure. Hypothyroidism can also cause mental health issues like depression and slowed mental functioning.
Hypothyroidism is usually treated with thyroid hormone medicine. Most symptoms of hypothyroidism start to improve within the first week after you start treatment. All symptoms usually disappear within a few months.
