Causes of Overactive Bladder
The bladder is more complicated than you might imagine, which can make it difficult to find the root causes of overactive bladder (OAB). A variety of blood vessels, nerves, and muscles must work together to keep everything flowing smoothly, so when something malfunctions (often, it’s the detrusor muscle), the whole system could collapse – leaving you with an embarrassing and frustrating problem.
Sometimes there isn’t any clear reason for your frequent trips to the toilet, sudden urgency, or small sporadic leaks, but in many cases, OAB can be traced to an underlying condition. Learn about the most common triggers so you can get the right diagnosis, and the right treatment.
1. Neurological Disorders
Conditions that affect the central nervous system, like multiple sclerosis and Parkinson’s disease, can interfere with nerves that pass signals between the brain and bladder. In the case of MS, the myelin coating of nerve cells degrades, and depending on where in the body that occurs, various automatic processes (like urination) may malfunction.
Parkinson’s disease involves a different nerve degradation process, but the results on the bladder can be the same: urge incontinence, stress incontinence, or conversely, urine retention. If you notice any other signs of central nervous system damage – tingling, weakness, vertigo, spasticity, or numbness – see your doctor right away about investigating your bladder issues further.
