“What causes creatinine levels to be high?”

The causes of high levels of creatinine are quite a few. However, some of them are kidney infection, impairment of kidney function, strenuous exercise, drug use, certain medication (any medication that is metabolized in. the liver), alcohol, consumption of protein, consumption of meat, last but no least, specific food supplements and vitamins. A great natural way to reduce your creatinine level is to by reducing you protein intake. Eating fiber-rich foods. Also fruits with high content ox antioxidants like cranberries, kiwi, applet, and blueberries. Thank you.

Almost always it is a sign of kidney failure. It would be prudent to see a neurologist.

There are many things including medications and diseases of the kidney, much too long to elaborate in a blog. You need advice and diagnosis by an Internist.
