Diabetic ketoacidosis, nondiabetic ketosis, and other factors can cause increased urinary ketone bodies, and measures can be taken to counteract this depending on the cause. Ketone bodies are intermediate metabolites in the oxidative metabolism of fats, and elevated ketone bodies in the urine occur when the rate of ketone body production in the liver exceeds the rate of utilization by extrahepatic tissues, and excess ketone bodies are excreted in the urine. Targeted treatment is needed depending on the cause. 1. Diabetic ketoacidosis: it is necessary to replenish fluids as soon as possible in order to restore blood volume, correct the state of water loss, lower blood glucose, correct the electrolyte and acid-base balance imbalance. When acidosis or even coma occurs, immediate resuscitation is needed. Prevention is the mainstay of this disease. 2. Non-diabetic ketosis: such as infectious diseases (pneumonia, typhoid fever, sepsis, tuberculosis, etc.), severe vomiting, diarrhea, prolonged starvation, fasting, etc. can also appear in the urine ketone body elevation. Treatment can be taken according to the cause of the disease, such as active anti-infection, looking for the original cause of vomiting, diarrhea, active treatment, food supplementation. There are many reasons for elevated ketone bodies in urine, it is recommended to go to the hospital in time to identify the cause and timely treatment.
