What causes urinary incontinence in young girls?

Leakage of urine in young girls may be caused by factors such as excessive fluid intake, negative emotions, urinary tract infections, cystitis, or enuresis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. Specific analysis is as follows:

1. Excessive fluid intake: Drinking large amounts of water or consuming too many diuretic foods—such as watermelon, winter melon, and tomatoes—can quickly fill the bladder beyond the child’s ability to control urination, leading to urine leakage. As the child grows older, bladder capacity and urinary control gradually improve. No special treatment is required; simply managing daily fluid intake is sufficient.

2. Negative emotions: Prolonged tension or anxiety may unconsciously relax the urethral sphincter muscles in young girls, resulting in urinary leakage. Psychological counseling is recommended to relieve stress and anxiety, which can help alleviate these symptoms.

3. Urinary tract infection (UTI): This may be related to poor personal hygiene or low immunity. When bacteria invade the urinary system, they can trigger an inflammatory response that disrupts normal function of the bladder and urethral muscles, causing urine leakage. Symptoms may also include frequent urination and urgency. Girls should follow medical advice and take medications such as fosfomycin trometamol powder, cefuroxime axetil tablets, or nifuratel tablets as prescribed.

4. Cystitis: This may result from abnormalities in the urinary system or upper urinary tract infections. When the urinary system is compromised, bacteria can infect and inflame the bladder. Chronic or recurrent inflammation may irritate the bladder and impair urethral muscle function, leading to urine leakage. The child may also experience symptoms such as urgency and painful urination. Treatment should follow medical guidance and may include medications such as cefadroxil granules, amoxicillin granules, or erythromycin tablets.

5. Enuresis: This may be associated with genetic predisposition or psychological factors. Delayed development of the cerebral cortex can lead to immature bladder development, resulting in nighttime bedwetting and daytime urine leakage. Medications such as oxybutynin hydrochloride tablets, mirabegron sustained-release tablets, or traditional Chinese medicine formulas like Buzhong Yiqi Wan may be used as directed by a physician.

In daily life, parents are advised to guide their daughters in appropriate bladder training exercises to enhance urinary control. Additionally, regularly reminding children to change and wash underwear and maintain proper genital hygiene can support recovery and overall urinary health.
