Question
Symptom Description: My child suddenly felt the need to urinate frequently last night, unable to fully empty the bladder, leading to difficulty in sleeping. The child is 6 years old and has been learning to swim recently; could this be a cause?
Answer
Based on the description, it is medically believed that children, due to their vigorous metabolism, often consume more water daily and have smaller bladders, leading to increased frequency of urination. Possible causes may include urinary tract inflammation, diet-induced polyuria, special diseases such as diabetes or diabetes insipidus, urethral and seasonal factors, as well as nervous urinary frequency. If there is a lot of urination accompanied by thirst and weight loss, a urine test is necessary to determine if it is diabetes or diabetes insipidus. If there is not much urination and no other symptoms, it may be due to regional factors such as urethral inflammation or pinworm irritation in the genital area. Frequent urination during winter is also a normal phenomenon. If frequent urination is painless and no other symptoms are present, consider regional factors first, such as urethral inflammation, phimosis, or pinworm irritation in the genital area. Additionally, seasonal factors, such as frequent urination during winter, are normal. If there is not much urination and no other symptoms, it may be due to regional factors such as urethral inflammation or pinworm irritation in the genital area.
