Whether or not it is normal for a child to urinate a lot depends on how much water he or she consumes each day. It is normal for children to urinate more if they drink more water, but it may be abnormal if they do not drink much water or if they urinate more often immediately after drinking water.
When a child does not drink much water, and the room temperature is not high and sweating is low, he or she may drink and urinate more because the bladder sphincter is not well developed and the bladder capacity is small.
If the intake is not much, but there is more urination and even swollen eyes, we should be highly alert to whether there is kidney function abnormality, may need to go to the hospital to do urine routine as well as kidney function test, early detection and early treatment.
If you drink more water and immediately excreted, and more urine, to be alert to the existence of uremia, to carry out routine urinalysis, to see whether the osmolality of urine is normal, if there is uremia should be given in a timely manner to the symptomatic drugs, as well as to identify the cause of uremia symptomatic treatment.
