Hypokalemic periodic paralysis cannot be completely cured. This disease, also known as hypokalemic periodic paralysis, is an autosomal dominant genetic disease or sporadic disease, with sporadic being more common in China. The pathogenesis is still not completely clear, and it is considered to be related to the fluctuation of potassium ion concentration inside and outside the cell membrane of skeletal muscle. Under normal circumstances, the potassium ion concentration remains high inside the cell membrane and low outside the cell membrane, and when potassium ions move, it causes the potassium ions inside the serum to fall and the potassium ions inside the cell membrane to rise, leading to the production of tardive palsy in the muscles of the limbs. After treatment with potassium supplementation, the patient’s symptoms can be relieved in a short period of time, with a complete return to normal in as little as a few hours. However, this disease can recur, not because of one treatment and then no more attacks. In general, patients should be careful to avoid triggers, such as fever, infections, overeating and consuming large amounts of sugary drinks.
