Hyperkalemic Periodic Paralysis is a disorder causing occasional episodes of muscle weakness and high level of potassium in blood. It is an autosomal dominant disorder that is passed down through families. The paralysis is triggered by exercises, exposure to cold or by eating potassium-rich foods. The paralysis commonly occurs at shoulders and hips and usually lasts for 1 to 2 hours. Mutations in SCN4A gene is responsible for this condition.
