Why does a newborn baby not urinate for 4 days?

Normal newborns will urinate immediately after delivery, and some newborns will urinate during the delivery process. However, some newborns also do not urinate two or three days after birth. This is actually normal and there is no need to worry. Why does a newborn baby not urinate after 4 days? This may be because the newborn was not fed after birth, the newborn took in too little fluid, or the newborn evaporated too much water through breathing or skin, so don't worry too much.

1.4 Reasons why newborns do not urinate

What causes anuria in newborns? Normal newborns tend to urinate immediately after delivery or during the delivery process. But some newborns do not produce urine in the first two to three days after birth. This may be because the newborn was not fed after birth, the amount of fluid intake was too little, or too much water was exhaled and evaporated from the skin. It may also be caused by uric acid infarction due to the presence of more urate crystals in the newborn's urine. Therefore, newborns should start breastfeeding within twelve hours after birth to ensure adequate water. If there is still no urine after the above time, you should check whether there is urine in the bladder and you can wait patiently. If anuria lasts too long, the newborn should be considered to have renal malformation or renal failure and should be sent to the hospital for further observation and examination.

What should I do if my child has no urine after birth? Normal newborns have very little urine output in the first few days after birth. Some children may not urinate for two days after urinating once during delivery or after birth. This is not abnormal. Because newborns drink very little water and milk in the first few days after birth, and after living independently away from the mother's body, their skin and breathing begin to emit moisture. Furthermore, the high urate content in the urine of newborns can block the renal tubules and cause temporary anuria, which is also the reason for oliguria in newborns in the early stage. After 1 week, as the amount of fluid intake from breastfeeding, drinking water, etc. increases, the blood circulation volume also increases, and the urine volume begins to increase. Generally, the urine volume is small within one week after birth, 3 to 4 times a day; after one week, it can increase to 20 to 30 times a day, and the amount also increases. After 6 months, the urine volume gradually decreases. Some parents become anxious when they find that their child has no urine within one day after birth, and immediately take the child to the hospital, which increases the newborn's chance of contact with patients. This is not good for the child and is unnecessary. You can first feed your child some glucose water and breastfeed as soon as possible, and the urine volume will increase. If the baby still has no urine within 48 hours after birth, you should ask a doctor to check for kidney malformations or other kidney diseases.
