During dialysis, what muscle groups are most commonly affected by cramping?

Muscle cramping during dialysis is most commonly associated with the extremities, which include the arms and legs. This phenomenon can occur for various reasons, such as changes in electrolyte balance, fluid shifts, or prolonged immobility during treatment. The extremities are particularly vulnerable because they are often more distanced from the core circulation and can experience changes in blood flow and muscle perfusion during the procedure.

While cramping can theoretically happen in other muscle groups, it is the extremities that frequently report the most incidents of cramping, likely due to the factors previously mentioned. Understanding this can help in anticipating potential complications and preparing appropriate interventions, such as stretching, repositioning, or administering electrolytes, to alleviate discomfort for patients undergoing dialysis.
