Patient's question:
My child is only 14 days old and had blood drawn at the hospital, where they found small congenital hypokalemia. They haven't been treated yet. Could you please tell me what symptoms are associated with congenital hypokalemia and whether it can be cured?Doctor's answer:
Congenital hypokalemia is caused by defects in ion channels on the cell membrane, leading to an abnormally low concentration of extracellular potassium ions. It is a relatively severe condition, and before the onset, patients may experience abnormal limb pain or sensations. Gradually, symmetrical weakness or collapse of the limbs may occur, with the lower limbs being more affected than the upper limbs, and the proximal parts of the limbs more than the distal parts. The muscles of the affected limbs may have reduced tone, weakened or absent tendon reflexes, and may be accompanied by aching, tingling sensations in the limbs. In very rare cases, it can lead to respiratory paralysis, urinary and fecal retention, tachycardia or bradycardia, arrhythmia, hypotension, and even life-threatening conditions. The primary treatment measure is potassium supplementation, and congenital diseases are generally difficult to recover from on their own.
