Pregnant women with high urinary ketone bodies after controlling blood glucose, if blood glucose is normal and urine sugar negative consider insufficient intake caused; if blood glucose is elevated and urine sugar positive consider diabetic ketosis. 1. Pregnant women may experience severe vomiting and loss of appetite during pregnancy, which in turn affects glucose metabolism, leading to an increase in fat decomposition and an accumulation of ketone bodies in the body, resulting in positive urine ketones; at the same time, if excessive dieting is done to control blood glucose, it will also result in a positive urine ketone body in pregnant women. It is recommended to adjust the diet under the guidance of a nutritionist to ensure daily nutrition and calorie intake. 2. If the pregnant woman’s blood glucose control is not up to standard, with elevated blood glucose and positive urine glucose, diabetic ketosis should be considered. Excessive blood glucose and insulin deficiency or resistance result in glucose not being taken up and utilized by the tissues, leading to lipolysis, which produces ketone bodies and positive urine ketone bodies. Pregnant women must be guided by their doctors for proper sugar control and take regular pregnancy tests.
