When doing urine tests, if there are many ketone bodies, the following possibilities need to be considered: First, there is a relationship with poor blood sugar control, if there are ketone bodies inside the urine, because the patient has diabetes or gestational diabetes caused by. During the treatment of this disease, if the blood sugar control is unstable, particularly high blood sugar will lead to excessive consumption of ketone bodies, causing positive urine ketone bodies, which can easily lead to ketoacidosis, to actively deal with, and at the same time to regularly recheck urine ketone bodies, and blood sugar checks. Secondly, if there has been no food for a long time when the examination is done, it will also lead to ketosis, called starvation ketosis, which is a compensatory state of the body and can be recovered soon after eating something.
