Introduction
In general, the main causes of urinary leakage include aging, pregnancy and childbirth, stress urinary incontinence, urgency urinary incontinence, and neurogenic bladder. If symptoms of urinary leakage occur, it is recommended to seek timely diagnosis and treatment at a正规 hospital. In daily life, it is important to maintain a healthy weight to avoid increased abdominal pressure caused by obesity; reduce the intake of stimulant beverages such as coffee and strong tea, to avoid irritating the bladder.
Generally speaking, the main causes of urine leakage mainly include aging, pregnancy and childbirth, stress urinary incontinence, urgency urinary incontinence, neurogenic bladder, etc. If symptoms of urine leakage occur, it is recommended to seek timely diagnosis and treatment at a regular hospital. Detailed analysis is as follows:
1. Aging
With increasing age, the elasticity of the pelvic floor muscles gradually weakens and the function of the urethral sphincter declines, making it difficult to effectively control urine discharge, which may lead to urine leakage. Performing Kegel exercises regularly can help strengthen the pelvic floor muscles by actively contracting and relaxing them, thereby improving urinary control.
2. Pregnancy and Childbirth
During pregnancy, the enlarged uterus compresses the pelvic floor tissues, while during childbirth, the pelvic floor muscles may be excessively stretched or even injured, causing the pelvic floor support structures to become loose and leading to urine leakage. Pelvic floor muscle rehabilitation training should begin as early as possible postpartum, such as biofeedback therapy, which uses instruments to assist in sensing pelvic floor muscle activity and provides targeted training.
3. Stress Urinary Incontinence
When abdominal pressure suddenly increases, insufficient urethral closure pressure causes involuntary leakage of urine. This commonly occurs in individuals with pelvic floor muscle relaxation. In addition to consistently performing Kegel exercises, mid-urethral sling surgery may be considered to enhance urethral support through surgery and alleviate urine leakage.
4. Urgency Urinary Incontinence
Overactivity of the bladder causes a sudden strong urge to urinate that cannot be delayed, resulting in urine leakage. This condition is often related to unstable detrusor muscle of the bladder. Under a doctor's guidance, medications such as Tolterodine Tartrate Tablets or Solifenacin Succinate Tablets may be used to inhibit detrusor muscle contractions and relieve symptoms of urgency and urine leakage. At the same time, it is important to maintain scheduled urination to avoid excessive bladder fullness, which could worsen symptoms.
5. Neurogenic Bladder
Nervous system disorders affect the neural control of the bladder and urethra, leading to abnormal bladder urinary control and causing urine leakage. It is important to actively treat the underlying condition first—for example, controlling blood sugar levels with Insulin Injection. Additionally, under medical guidance, Mecobalamin Tablets may be used to nourish nerves and improve nerve function. When necessary, intermittent catheterization may be performed to help empty the bladder, reducing episodes of urine leakage.
In daily life, it is important to manage body weight to avoid increased abdominal pressure caused by obesity; reduce intake of stimulant beverages such as coffee and strong tea to avoid bladder irritation; maintain scheduled urination and avoid prolonged urine retention; and undergo regular pelvic floor function examinations to detect and address issues promptly, maintaining urinary system health.
