Overactive bladder disorder (OAB) literally explains the problem of this disease. Because of the overactive bladder, the bladder suddenly contracts abnormally when the urine is not stored in sufficient volume to urinate, and the pressure in the bladder suddenly increases, causing sudden urgency. In addition, some patients may have symptoms of frequent urination and nocturia at the same time.
What are the symptoms of overactive bladder (OAB)?
Symptoms in a typical case include urgency, frequency, nocturia and possible incontinence during urgency, with urgency being the most common symptom. Urge to urinate is a sudden, strong urge to urinate and is difficult to delay by subjective suppression. The urge to urinate is accompanied by, or immediately follows, urge incontinence, and in severe cases, all of the urine is relieved without feeling it. Frequent urination, on the other hand, is when patients feel that they are urinating too often each day. On the basis of subjective feeling, the number of times an adult urinates: ≥8 times during the day, ≥2 times at night, and <200ml per urine volume is considered as frequent urination. Nocturia is the complaint of getting up to urinate after going to sleep due to the urge to urinate, and generally ≥2 times at night is considered nocturia. Patients may present with any one or several of these symptoms. Less common symptoms include bedwetting. What causes overactive bladder (OAB)? The causes of OAB symptoms are varied. Overactive bladder (involuntary contraction of the detrusor muscle during filling) is thought to be the underlying cause of most cases of OAB. Secondly, forced urinary muscle overactivity can be neurogenic or myogenic, but in most cases the cause is unknown.
