What is the reason for children to urinate frequently? How to judge

Some parents think that their children urinate frequently and worry that there is something wrong with their kidneys. First of all, parents need to understand what frequent urination means. For example, for children between six months and one year old, the normal urination frequency is about 15 times a day.

How much urine is normal for babies? The amount of urine for babies at different ages is different. In the first few days after birth, the baby's urine output may be very small, about 80 ml per day, due to the small amount of food intake; the daily urine output at 3 to 4 days is 80 to 300 ml; the daily urine output from 10 days to 2 months is about 400 to 500 ml; the daily urine output from 1 to 3 years old is about 500 to 600 ml.

1. Abnormal:

If your baby's urine volume is more than 800 ml a day, excluding the possibility of drinking too much water, he may be suffering from diabetes insipidus.

If the baby has oliguria or anuria, it is mainly seen in acute renal failure caused by various reasons, including prerenal, renal, and post-renal acute renal failure.

Tips: Due to factors such as physical constitution, daily water intake, temperature, etc., there may be certain differences in urine volume between different individuals.

2. How often your baby urinates

Babies of different ages urinate at different times a day. Generally speaking:

Newborns 4-5 days after birth: urinate 4-5 times a day;

After one week: Due to the high metabolism of children, 20-25 times a day is normal, and even up to 30-40 times;

6 months to 1 year old: With the increase of semi-liquid complementary food and the gradual improvement of kidney function, the number of urinations per day is reduced to 15 to 16 times;

2 to 3 years old: The average number of urinations per day is 10;

4-8 years: 6-7 times.
