Many cases probably result from a mix of factors including slower physical development, an overproduction of urine at night, a lack of ability to recognize bladder filling when asleep, and, in some cases, anxiety. A strong family history of bedwetting suggests an inherited factor. Incontinence in younger people can also be a complication of diabetes, stroke, multiple sclerosis, and Parkinson's disease. High impact exercise can cause incontinence, particularly in young women. Temporary Incontinence A number of conditions can cause temporary incontinence, including urinary tract infections, excess fluid intake, constipation, severe depression, and restricted mobility.
Drugs are most likely to be the cause of temporary incontinence.
Drugs that affect the adrenergic system, a nerve-cell and hormonal pathway that regulates the sphincter muscle, can cause incontinence. Diuretics, which are used for high blood pressure, often rapidly introduce high urine volumes into the bladder. Colchicine, a drug used for gout, can cause urge incontinence. Calcium-channel blockers can cause overflow incontinence by relaxing the bladder detrusor muscles. Other medications and substances that increase the risk for incontinence are caffeine, sedatives, antidepressants, antipsychotics, and antihistamines.
