Does dialysis invalidate fasting?

Question

The inquirer says, "I suffer from renal failure which necessitates undergoing dialysis three times a week. Blood is pumped through a device that filters waste from the blood and replaces lost minerals and vitamins. Please note that the procedure is performed via arteries and veins. My question is whether dialysis invalidates fasting or must only be performed after I break my fast."

Answer


There is no harm in undergoing dialysis while fasting provided the procedure is performed via veins and arteries. Based on this, dialysis does not invalidate fasting.

The answer is known from the above and Allah the Almighty knows best.
