Definition
Thyrotoxic periodic paralysis is a condition in which there are episodes of muscle weakness in people with high levels of thyroid hormone (hyperthyroidism, thyrotoxicosis).
Overview, Causes, & Risk Factors
Thyrotoxic periodic paralysis is a rare condition that occurs only in people with high thyroid hormone levels (thyrotoxicosis). It is seen most commonly in Asian men.
There is a similar disorder, hypokalemic periodic paralysis (familial periodic paralysis). This is an inherited condition and does not have high thyroid levels.
Risk factors include a family history of periodic paralysis and hyperthyroidism.
