By Mayo Clinic staffIf you experience unexplained weight loss, a rapid heartbeat, unusual sweating, swelling at the base of your neck, or other signs and symptoms associated with hyperthyroidism, see your doctor. It's important to completely describe the changes you've observed, because many signs and symptoms of hyperthyroidism may be associated with a number of other conditions.
If you've been treated for hyperthyroidism or currently are being treated, see your doctor regularly so that he or she can monitor your condition.
