Cough leakage is generally referred to as urinary incontinence and may be associated with various reasons such as age, vaginal delivery, obesity, prostate enlargement and cystitis. 1. Age: This condition is mostly seen in women, especially middle-aged and elderly women. With age, the decrease of estrogen level after menopause will lead to the relaxation of pelvic floor muscles, and the change of urethra angle and bladder angle, which may cause urinary incontinence after coughing. 2. Vaginal delivery: women who have given birth to a woman and women who have given birth to many women are also prone to similar phenomena. After a woman gives birth to a woman vaginally, due to the relaxation of the sphincter muscles or pelvic floor muscle prolapse, which can cause urinary incontinence. 3. Obesity: excessive obesity increases the pressure on the bladder and surrounding muscles, and urine leakage may occur when coughing. 4. Cystitis: Infection irritates the bladder, causing a strong urge to urinate, which may lead to urinary incontinence, and can usually be accompanied by symptoms such as urinary urgency, urinary pain, and urinary frequency. 5. Prostatic hyperplasia: Prostatic hyperplasia presses on the bladder, leading to coughing and urine leakage. It can usually be accompanied by urinary retention, dysuria, abdominal enlargement, frequent urination and other symptoms. There are many causes of urinary incontinence after coughing, and it is recommended that patients go to the hospital in time to clarify the cause of the disease.
