"I have found that those patients who have gone to the Internet and obtained accurate medical information come to their appointment with me very well informed, and the discussions regarding the evaluation and management of their condition are very productive and satisfying," he says.
"The key, however, is obtaining accurate medical information. As a medical editor, I hope to be able to ensure that accurate, relevant and up-to-date information is available for patients and their families."
Thyroid disease: Can it affect a person's mood?
Can thyroid disease affect my mood?
from Todd B. Nippoldt, M.D.
Yes, thyroid disease can affect your mood — primarily causing either anxiety or depression. Generally, the more severe the thyroid disease, the more severe the mood changes.
If you have an overactive thyroid (hyperthyroidism), you may experience unusual nervousness, restlessness, anxiety and irritability. On the opposite end of the spectrum, if you have an underactive thyroid (hypothyroidism), you may experience mild to severe fatigue and depression.
Still, it's unlikely that emotional symptoms such as anxiety or depression would be the only evidence of thyroid disease. Thyroid disease is usually associated with signs and symptoms such as weight gain or loss, sensitivity to hot or cold, bowel movement changes, and menstrual irregularities.
Appropriate treatment — such as medication that blocks your body's ability to produce new thyroid hormone or replaces missing thyroid hormone — usually improves both emotional and physical symptoms caused by thyroid disease.
