Ketone body 1+ generally refers to a certain amount of ketone bodies in the urine, reflecting the body’s metabolism of blood glucose, need to be combined with clinical symptoms to determine the overall. Generally speaking, urine does not contain ketone bodies, and the presence of ketone bodies 1+ suggests that the body’s metabolism of blood sugar is abnormal, accompanied by a certain amount of fat consumption. The main causes of this condition are starvation and unstable blood glucose control. Starvation with a small amount of fat metabolism can cause a positive urine ketone body, as can poor glycemic control, which results in fat depletion. Urinary ketone bodies 1 + need to monitor blood glucose levels, find abnormalities in a timely manner, and under the guidance of clinicians to regulate the condition, to avoid causing delays.
