If urinary ketone bodies (++) are present, it is likely that the symptoms are caused by diabetes, because diabetic patients are prone to acute complications of ketoacidosis, which can cause an increase in the level of ketone bodies in the urine. Patients with ketoacidosis may also have thirst, weakness, rotten apple taste in the mouth, and some may have mental symptoms such as irritability, and in severe cases, coma, which need to be checked and clarified as soon as possible and then given timely treatment intervention to avoid serious consequences. This condition generally requires first strict control of blood sugar, and then a large amount of fluids to improve the metabolism of the body.
