My father has a urine infection since last 15 days. His creatinine is 4.8. The ultrasound report showed enlarged prostate and intact kidney size. He lost appetite since last one month. He is only taking a half glass of milk daily only. His fasting sugar was 113. He is a diabetes patient and taking Insulin 5 units during the day and night. Now, this has been stopped by his doctor due to low intact. Kindly suggest a further line of treatment.
