What kind of exercise should people with ion channel diseases undertake?
HYPOKALEMIC PERIODIC PARALYSIS There are no specific guidelines as to what level of exercise is appropriate for HypoKPP. What we do know is that most people with HypoKPP note that if they undertake strenuous exercise which is atypical for them, followed by rest or sleep, they will precipitate an attack. Factors that increase the likelihood of an attack after exercise include a meal rich in carbohydrates and sodium, alcohol consumption, exposure to cold and emotional stress. The severity of the episode may vary from mild weakness to severe generalized paralysis. The facial, respiratory and sphincter muscles are generally spared.
