According to the data you reported (frequent urge to urinate almost to degree of urine incontinence), it seems likely that you might be experiencing overactive bladder syndrome. Overactive bladder syndrome is a condition in which the detrusor (the muscle that contracts in order to expel the urine from the bladder) contracts involuntarily without any control. This causes the urge to urinate and combined with a weak bladder sphincter might lead to urine incontinence.


In this condition there is no actual shrinking of the bladder. Shrinking of the bladder is often mistaken for this condition.


The causes for hyperactivity bladder syndrome are not quite well understood. However, there are several pieces of advice that might help you at least improve the condition. Avoiding caffeine, which acts as a diuretic, and alcohol in various people might reduce the quantity of urine filled over time. Training the bladder to keep more urine over time might “teach” the detrusor muscle to keep the increased quantity of urine inside the bladder. If there is also stress incontinence present it might be solved with pelvic floor exercises.


Medications called anticholinergics might be used to try to control the detrusor. Consult with a doctor before taking any of these medications because they might have serious side-effects if given in larger doses and if given when other specific health conditions are present.


In the end, there are also surgery procedures (sacral nerve stimulation, augmentation cystoplasty, and urinary diversion), which are recommended in very severe cases of overactive bladder syndrome.


You might want to visit a urologist to talk about the treatment options and pelvic floor exercises, if needed.
