What happens when you have thyroid problems?
Thyroid hormone imbalances
When your thyroid produces too many or too few hormones, it can cause imbalances that are associated with a host of symptoms.Hypothyroidism is the term for an underactive thyroid, one that produces too few hormones, and hyperthyroidism describes an overactive thyroid, one that produces too many hormones.Hypothyroidism is much more common — the National Institutes of Health reports that nearly 1 in 20 Americans over the age of 12 have the condition — whereas hyperthyroidism is reported to affect only 1 in 100.
