Buttermilk (chaas) is a moderate-potassium dairy drink with added salt. Early CKD: fine in a glass. Stage 4-5 and dialysis: limit it — the potassium, salt, and fluid add up quickly.
Buttermilk carries milk's potassium and a sodium load from added salt — the classic Indian chaas is saltier than plain yogurt drink.
For early-stage CKD, a glass is fine; for advanced CKD and dialysis, the potassium plus sodium plus fluid makes it a limited item.
Bottom line: unsalted buttermilk in small portions is the renal-safe version; count it as fluid on dialysis.
