# Acute flaccid paralysis secondary to severe hyperkalaemia

## TL;DR

A patient experienced sudden muscle weakness and facial nerve issues due to dangerously high potassium levels, which was successfully treated.

## Contribution

This case highlights flaccid paralysis as a rare but critical sign of severe hyperkalaemia.

## Key findings

- Flaccid paralysis with cranial nerve involvement was linked to severe hyperkalaemia.
- ECG and lab results confirmed the diagnosis of life-threatening hyperkalaemia.
- Symptoms resolved completely after treatment for hyperkalaemia.

## Abstract

Acute Flaccid paralysis is a rare presentation of severe hyperkalaemia, described rarely in the literature. We report a case of flaccid paralysis, including cranial nerve involvement, secondary to hyperkalaemia in a patient presenting to A&E. Initial ECG showed signs of severe hyperkalaemia and lab results confirmed. The patient was started on hyperkalaemia treatment which reversed his symptoms completely, thus confirming the diagnosis. Flaccid paralysis is a rare presentation of life threatening hyperkalaemia and its recognition is essential in initiating life-saving antihyperkalaemic treatment.
