Thyroid disease is a condition that affects the thyroid gland, which is responsible for producing hormones that regulate metabolism, growth, and development. Symptoms of thyroid disease can include fatigue, weight gain or loss, changes in appetite, difficulty sleeping, dry skin, and more. It is important to check for symptoms of thyroid disease and to understand your family history of the condition. Your doctor may recommend blood tests to check for thyroid hormone levels, as well as imaging tests to look for any abnormalities in the thyroid gland. Additionally, it is important to discuss any family history of thyroid disease with your doctor, as this can help them determine if you are at risk for developing the condition.
