The addition or subtraction of urinary ketone bodies is clinically called urinary ketone body trace, which is more than negative and not yet at a plus level. Most often, two conditions can lead to an increase in urinary ketone bodies, the most common being diabetic ketosis, mainly seen in patients with diabetes who have higher average blood glucose, and stressful conditions such as infections, which can lead to high urinary ketone bodies. It may also cause the patient to eat poorly and be in a chronic state of hunger, which can also produce urinary ketone bodies. The urinary ketone body plus or minus is not a big problem, we should drink more water and excrete the excess ketone body from the body appropriately, it may turn negative when we recheck the ketone body, and clinically it does not need much treatment. If it is caused by high blood sugar, give appropriate treatment to control the blood sugar, the abnormal ketone body condition will disappear.
