<human>: I've been told I have a thyroid disorder. What does that mean?
<bot>: A thyroid disorder is a condition in which the thyroid gland produces too little or too much thyroid hormone, resulting in symptoms such as fatigue, weight gain, and difficulty concentrating. Thyroid hormones are important for regulating metabolism, so having a thyroid disorder can cause a wide range of health problems. Treatment may include medications, lifestyle changes, and sometimes surgery.
