Can Fasting Help With Kidney Disease?

A recent study has sought to explore the effects of an 11-day complete water fasting and regeneration diet on renal function, body weight, blood pressure and oxidative stress.

Therapeutic WF is considered a healing method.

Ten participants drank water for 11 days, followed by adopting the  Regeneration Diet for the subsequent 11 days. Data on body weight, kidney functions, antioxidants, blood pressure, lipid peroxidation, triacylglycerols, cholesterol and selected biochemical parameters were obtained.

Here were a few of the study’s most interesting findings:

  • WF (Water Fasting) increased uric acid and creatinine and decreased glomerular filtration rate. After RD, the parameters were comparable to baseline values. Urea was not affected.
  • Lipid peroxidation (TBARS) decreased and maintained stable after RD.
  • Fasting decreased α-tocopherol and increased γ-tocopherol, no significant changes were found after RD.
  • Coenzyme Q10 decreased after RD.
  • HDL-cholesterol decreased in WF.
  • Total- and LDL-cholesterol decreased after RD.
  • Other biochemical parameters were within the range of reference values.

In conclusion, effects of fasting on the kidneys were manifested by hyperuricemia. Renal function was slightly decreased, however it was maintained within the reference values. After RD, it returned to baseline values. The positive effect of complete water fasting was the reduction of  body weight, oxidative stress and blood pressure.

Warning: Fasting in this study provided some interesting results. However, before fasting with kidney disease or any other medical condition please consult your physician.
