Can kidney deficiency cause high blood sugar?

Kidney deficiency does not cause high blood sugar. Kidney deficiency and high blood sugar are two distinct conditions. Kidney deficiency is a concept in traditional Chinese medicine, while high blood sugar is a Western medical diagnosis. If you have kidney deficiency, it can be treated with kidney-tonifying medications. Elevated blood sugar is primarily caused by excessive sugar intake and obesity. If you have abnormal blood sugar levels, you should visit the internal medicine department at a hospital and undergo a fasting blood glucose test.
