  • Dialysis disequilibrium syndrome (DDS)

    Dialysis disequilibrium syndrome is when a group of neurological symptoms occur to patients on hemodialysis due to the sudden and rapid removal of urea, a waste product, from your blood. These symptoms include nausea, headaches, vomiting and restlessness. More serious symptoms can result in seizures and comas.
