[|Human|] my father has undergone CABG last week. He is now under CAPD for last 1 month. After the surgery there is lot of swelling in legs and hands. The swelling in the hands has come down after the CAPD but the legs are still showing the swelling and from yesterday we are observing some red patches in his toe and foot. Please tell me the cause of it.
[|AI|]  Swelling is because of kidney dysfunction. Kidney is not able to excrete water so need to consume fewer fluids. As it is resolving with card, it will resolve within some time. If not consult your nephrologist to increase dose if Chat Doctor. Red patches may be because he must be taking blood thinners together with kidney dysfunction lead to excessive blood thinning lead to red patches. Still you need to show those patches to your doctor.
