The rare neurological disorder of familial hypokalemic periodic paralysis (hypoPP) causes intermittent muscle paralysis that might lead to hospitalization with acute intensive care and sudden cardiac arrest. Reported lifestyle triggers include carbohydrate rich meals and hard physical activity, and may include salt intake, over-eating, alcohol consumption, dehydration, and rest after exercise. However, effective lifestyle treatments are lacking in the scientific literature and current knowledge rely on expert opinions, case-reports, and retrospective case studies. To our knowledge, this is the first case-report to describe modifications of lifestyle with positive impact on prevention of paralytic attacks despite strenuous physical activity. The case has prevented paralytic attacks by securing regular meals, a diet low in carbohydrate and high in potassium, avoiding fast-food, securing large fluid intake, and a less stressful every-day life. To prevent paralytic attacks in relation to strenuous physical activity, the patient uses oral potassium chloride supplements, pre-workout carbohydrate rich meal, followed by a post-workout potassium rich protein shake and an additional 2 L water.
