Hello Maya and welcome!

I have that occasionally. I assume it's just the body doing its thing. In any case if it is the first time it happened it surely is not reason to be terrified.

Maybe someone can be more helpful but know that changing to this woe is the single best thing you can do for your health.

From what I understand, when you first start keto your body produces too many ketones and your body excretes them through your urine. To flush them your body produces the oily stuff you see. Once you adapt it will make the right amount of ketones and it should clear up. As a borderline diabetic it is important to note whether your urine is milky along with oily. If it is, then it is a reason to see your doctor.
