Frequent urination refers to the increase in the number of urination, which is relatively common in children. The causes of frequent urination can be divided into physiological frequent urination and pathological frequent urination. Physiological frequent urination is mainly seen in excessive drinking, cold weather, or when there is tension and anxiety, there will be more frequent urination, but not accompanied by painful urination and other symptoms, generally by reducing the amount of water, avoiding tension and anxiety, and timely relief of symptoms can be relieved. Some male babies have long foreskin, or prepuce can also lead to frequent urination, this need to pay attention to the surgery to see if surgery is needed. Pathological frequent urination, such as diabetes and urolithiasis and other diseases caused by excessive drinking, polyuria. In addition, it can also be caused by medications, such as increased urine output after the use of medications such as diuretics and dehydrating agents in children with edema and ascites. This kind of frequent urination caused by increased urine volume is characterized by frequent urination but a large volume of urine at a time. If your baby also has symptoms such as urinary urgency and painful urination, you should be alert to the presence of urinary tract infections and have a routine urine test or urine culture to see if there is an infection or what type of bacterial infection is present. If your baby has bladder stones, a congenital tumor or foreign body in the urinary system, it can cause frequent urination, and you need to have an ultrasound of the urinary tract to see if there are any abnormalities. Another possible cause of frequent urination in children is neurogenic frequency. Neurogenic dysuria is mainly characterized by an increase in the number of urinations per day without an increase in urine volume, and a normal routine urine examination. The frequency of urination increases from the normal 6-8 times per day to 20-30 times per day, or even more than 10 times per hour, but the volume of urination is very small, sometimes only a few drops per time. After falling asleep, the frequency of urination disappears completely. During the day, when playing with beloved toys or watching favorite TV, the frequency of urination is significantly reduced. Often, before going to bed or when eating, the frequency of urination increases significantly. When parents find that their baby urinates frequently, they should not reprimand the baby to make him anxious and add to his psychological burden, but should look carefully for the cause of frequent urination and deal with it symptomatically.
