Question
The child has recently been experiencing symptoms of frequent urination and incomplete voiding, especially at night, which affects their sleep and makes it difficult for them to fall asleep. The description mentions that the child is learning to swim, and the question is whether this could be related to the symptoms. There is no history of treatment, and the individual hopes to understand the cause and obtain a solution.
Answer
Based on the description, the child may be experiencing an increased frequency of urination due to drinking more water and having a smaller bladder capacity. This is quite common in children in development. The main reasons include: ① Urinary tract infections, such as frequent urination, urgency, dysuria accompanied by fever, which may indicate cystitis or pyelonephritis, and can be detected through urinalysis for microscopic pus cells or a large number of white blood cells. In severe cases, systemic infection and intoxication symptoms may occur, requiring antibiotic treatment. ② Diet-induced polyuria, if there is frequent urination with a large volume of urine each time without other symptoms, it is first considered whether too much water is being consumed, especially for children who like sugary drinks. ③ Special diseases, if frequent urination is accompanied by polyuria and excessive thirst with weight loss, check the urine; if it contains sugar, it may be diabetes; if the urine specific gravity is low, it may be diabetes insipidus. ④ Urethral and seasonal factors, if there is frequent urination but little urine each time without discomfort, consider regional factors first, such as urethral inflammation, phimosis, or pinworm irritation in the genital area. Increased urination in winter is also a normal phenomenon. ⑤ Neurogenic frequent urination, if a child’s detrusor muscle in the bladder is underdeveloped, it may also cause frequent urination.
