Frequent urination is a condition in which the frequency of urination increases. The causes of frequent urination can be divided into physiological and pathological frequent urination. Physiological urinary frequency is mainly seen when drinking too much water, cold weather, or when there is tension or 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, timely relief of symptoms can be alleviated. Some male babies with prepuce or prepuce can also cause frequent urination, and need to go to pediatric surgery for treatment. Pathological frequent urination can be seen in diseases such as diabetes mellitus and urolithiasis. 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, and you should treat it with medication in a timely manner. Babies with bladder stones, congenital tumors or foreign bodies in the urinary system can cause frequent urination and need to undergo a urinary ultrasound. 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 is urinating frequently, they should not scold the baby and add to the baby’s psychological burden, but should look carefully for the causes of frequent urination, treat the symptoms, and seek medical attention from the hospital in a timely manner to avoid delaying the condition.
