Hypokalemic periodic paralysis is a condition that causes episodes of extreme muscle weakness typically beginning in childhood or adolescence. Most often, these episodes involve a temporary inability to move muscles in the arms and legs. Attacks cause severe weakness or paralysis that usually lasts from hours to days.
What causes Hypokalemic paralysis?
People who have hypoPP have mutations in their genes that change the way these protein channels work. As a result, they don’t have enough of the potassium needed for their muscles to contract. This is what causes the muscle weakness and paralysis. The condition is an autosomal disorder.
Is there a cure for Hypokalemic periodic paralysis?
Oral potassium administration, assuming normal renal function, is the mainstay for treating attacks of hypokalemic paralysis. Here too, most patients are grossly under-dosed with respect to potassium supplementation during an attack. Large bolus doses are favored over smaller, spaced out, incremental doses.
What is the most common cause of hypokalemia?
Low potassium (hypokalemia) has many causes. The most common cause is excessive potassium loss in urine due to prescription medications that increase urination.
