<human>: My doctor has told me that I have a problem with my thyroid. What does this mean?
<bot>: Thyroid problems can cause a variety of symptoms, including fatigue, weight gain, depression, hair loss, dry skin and constipation. Your doctor may recommend tests to determine if you have an underactive or overactive thyroid. Treatment options include medication, lifestyle changes such as eating healthy foods and exercising regularly, and sometimes radioactive iodine treatment.
