Why does a newborn baby only pee but not poop?

Careful mothers will find that their babies will only wriggle for a period of time without excreting any stool. Many mothers think this is abnormal.

I am also worried that something might happen to the baby or I might get sick, so I often go to the hospital to see the doctor and listen to his advice. But generally speaking, as long as the baby does not defecate often, he is in a relatively healthy condition.

The baby's polyuria or oliguria is not determined by the mother's subjective idea, but is inferred by collecting the baby's urine volume for 24 hours a day. Generally speaking, medicine believes that if the baby's urine volume in 24 hours is more than 3000 ml/square meter of body surface area, it is polyuria, and if it is less than 250 ml, it is oliguria. This polyuria is physiological polyuria. In addition, babies will also have temporary polyuria during the recovery period of febrile diseases. However, if the baby's urine volume is particularly large, and he can eat and drink at the same time, but his weight is gradually decreasing, he may have diabetes. If blood sugar and urine sugar are tested, it can be seen that both are elevated.

The baby's frequent urination is caused by drinking less water or sweating more in hot weather, but this is usually a physiological phenomenon. Once the baby drinks more water and sweats less, the urine volume will soon return to normal; babies with severe diarrhea or kidney diseases, such as common acute glomerulonephritis, generally show oliguria or even anuria, but the former has a significant increase in the number of bowel movements, and the latter is accompanied by edema and high blood pressure symptoms; newborn babies with oliguria or anuria often indicate congenital urinary tract malformations.

The baby should be taken to the hospital for further examination as soon as possible. Of course, the mother should pay attention to exclude the frequent urination caused by mental factors. The baby's urine volume has not increased. As long as the mental factors causing frequent urination are eliminated, the symptoms of frequent urination will disappear immediately.

For babies who do not urinate but only defecate, mothers need to pay attention to distinguish whether this happens often. If so, it is best to go to the hospital for a check-up to see if there are any of the above symptoms. If not, then mothers can rest assured that this is just a transition period of the baby's physical development. There is no need to take the baby to the hospital for treatment. It is better to observe for a period of time first.
