Urine ketone bodies (++++) is a strong positive for urine ketone bodies, indicating a more severe elevation of ketone bodies in the body’s blood. The most common disease is ketoacidosis in diabetes, and some patients have severe vomiting and diarrhea. In times of hunger in the body, ketone bodies can replace glucose as a source of tissue energy. If the concentration of insulin in the plasma decreases, or if endocrine insulin is not secreted enough, the production of ketone bodies cannot be controlled by the body itself and will lead to an elevation of ketone bodies in the body. When ketone bodies are elevated in the plasma, urinary ketone bodies will also be shown as elevated ketone bodies in the urine along with a large amount of ketone bodies excreted in the urine. The treatment is to actively search for the cause of the disease, remove the cause as soon as possible, and then give rehydration and volume expansion to try to restore blood volume and correct the state of water loss and dehydration. In addition, insulin can be applied to lower blood sugar and blood ketone bodies. If the ketosis is caused by repeated vomiting and diarrhea, you need to give rehydration fluids quickly and also drink a lot of water to eliminate ketosis.
