Hi, I had gone through your question and understand your concerns. You should not be worried since complications are rare and usually not serious. More complications may occur if blood urea and creatinine grow above critical value. These values are significantly high and I consider that dialysis should be planned soon in consultation with your nephrologist. Complication are usually related to some changes in blood picture but this is usually handles by doctor on dyalsis and this should not worry you. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. Wishing you good health.
