  • Stay hydrated andavoid exercising in extreme temperatures
  • Wear appropriate footwear andinspect feet daily for brosters or sores

Patients on Dialysis or wich Nephropathy

Diabetes- related kidney disease further complicates blood pressure management. Exercise programs for individuals wich nefropathy should avoid excessive protein intake (supplementation) and account for fluid and elektrolite restrictions. Intradialtic cykling - stationary cyclg during dialysis sessions - has shown voche for improwising cardiovascular fitness and blood pressure control in this population.
