Clinical Information

Overactive bladder is a common condition that can significantly impact quality of life. It is characterized by symptoms such as urinary urgency, frequency, and nocturia (waking up at night to urinate). OAB can be caused by a variety of factors, including nerve damage, bladder inflammation, and muscle dysfunction.


The exact cause of overactive bladder is not always clear, but several factors may contribute to the development of this condition. These include age-related changes in bladder function, neurological disorders, urinary tract infections, and certain medications.


Individuals with overactive bladder may experience a range of symptoms, including a sudden and strong urge to urinate, frequent urination (more than eight times a day), and urge incontinence (leaking urine before reaching the restroom). Other symptoms may include nocturia, or waking up at night to urinate, and difficulty emptying the bladder completely.


Diagnosing overactive bladder typically involves a thorough medical history, physical examination, and possibly additional tests such as a urinalysis, bladder diary, or urodynamic testing. Healthcare providers may also use questionnaires to assess OAB symptoms and severity.


Treatment for overactive bladder may include lifestyle modifications, such as bladder training, pelvic floor exercises, and dietary changes. Medications, such as anticholinergics or beta-3 agonists, may also be prescribed to help control OAB symptoms. In some cases, advanced treatments such as botulinum toxin injections or sacral neuromodulation may be recommended.


Overactive bladder is a common and bothersome condition that can significantly impact quality of life. Proper diagnosis and treatment are essential for managing OAB symptoms and improving overall well-being. By understanding the ICD-10 code for overactive bladder and its clinical implications, healthcare providers can better track and address this condition in clinical practice.
