Question
An elderly patient with diabetes for 15 years and declining renal function has a creatinine level of 221., seeking advice on lowering the creatinine.
Answer
For elderly patients with diabetes for 15 years and renal function decline, the focus of treatment for high creatinine levels (221.) should be on blood sugar control. Controlling blood sugar is crucial for preventing further renal function damage. Medications to protect renal function are mainly symptomatic treatments and cannot truly lower creatinine levels. Insulin therapy, which controls blood sugar at its source, can effectively protect the kidneys and reduce the side effects of hypoglycemic medications.
