In late pregnancy, if a pregnant woman experiences urinary ketone bodies 2+ suggests that it could be due to starvation ketosis or hyperglycemic ketosis. Late pregnancy ketone body 2+ is a positive ketone body in late pregnancy, which generally means that ketone bodies are present among the urine of a woman in late pregnancy. It can be caused by the following reasons. 1. If a pregnant woman in late pregnancy is in a state of hunger when checking her urine routine, she may break down fat metabolism in her body and have ketone bodies in her urine. The urine ketone body can be negative by reviewing after eating. 2. If pregnant women in late pregnancy with higher than normal blood sugar, and poor blood sugar control, there will be a relative lack of insulin, metabolic disorders, accelerated fat decomposition, so the production of ketone bodies. It is necessary to carry out further blood glucose-related examination and timely hypoglycemic treatment. Specifically should go to the hospital, under the guidance of the doctor examination and treatment.
