Question
A four-month-old baby has shown a urine glucose result of 4+ on multiple urine tests, with such results occurring four or five times since birth. Although blood tests indicate normal blood sugar and kidney function, the doctor points out that it may be related to renal tubular issues and recommends further detailed examinations in major cities such as Beijing or Shanghai. As a breastfeeding mother, what precautions should I take, what foods should I eat, and what foods should I avoid?
Answer
Normal urine glucose is very rare, and it is not detectable by general methods, so normal urine glucose should be negative, or in other words, there should not be sugar in the urine. In normal individuals, sugar is more likely to be excreted in the urine when blood sugar is below 160~180 mg/dl. When blood sugar is between 200~250 mg/dl, urine glucose should be present; and when blood sugar is between 250~300 mg/dl, urine glucose should be evident. Abnormal urine glucose in babies may require further investigation to determine the specific cause and to develop an appropriate diet adjustment plan. While waiting for further examination, the mother should follow the doctor’s advice and pay attention to maintaining a balanced diet for the baby, avoiding excessive sugar intake and certain foods to prevent exacerbating the abnormal urine glucose condition.
