Common Causes of An Overactive Bladder (OAB)

When your bladder is unable to hold urine as it is supposed to, you’re most likely suffering from OAB (Overactive Bladder). Many people who have this condition get depressed and feel stigmatized because it is often associated with leaking urine. Because of this, many people choose to suffer in silence but the truth of the matter is there are many such similar case so you’re not alone.

Statistics have shown that approximately 33 million Americans suffer from OAB. In order to understand this condition, it is important to understand what causes an overactive bladder. There are different causes of OAB and it is critical to urgently deal with the symptoms in good time and get medication. Individuals with OAB usually have to urinate over eight times in a single day and multiple times at night. It’s worth noting that this condition can either exist on its own or be caused by other underlying health conditions. When you seek treatment early, you can be able to prevent the condition from becoming worse. The good news is aside from conventional medicines, there are effective home treatment remedies for OAB.

So, what are the causes of an overactive bladder?


As you become older, your chances having an overactive bladder significantly increase. Both men and women get OAB due to age with statistics showing many cases beginning after the age of 60. Young people with OAB are less than 10 percent which in this case, the trigger is often not age but an underlying health condition.

Weak Pelvic Muscles

When your pelvic muscles are weak, bladder control complications begin to emerge. In women, the pelvic muscles can become weak due to pregnancy and childbirth which causes stretching and weakening of the pelvic floor muscles. If these muscles are compromised in any way, the bladder hangs out of the position making it easy for urine to leak out.

Damaged Nerves

When your bladder is functioning normally, it comfortably holds urine until it gets full and nerve signals guide the bladder when it is time to urinate. When nerves are damaged, the muscles around the urethra weaken causing incontinence. Nerves can be damaged due to a number of causes such as diabetes, herniated disc, Parkinson’s disease, back or pelvis surgery, stroke and multiple sclerosis among other medical conditions.


Having excess body weight causes a number of health conditions including having an overactive bladder. Too much weight puts excess weight on the bladder and so it’s always important to watch your weight and exercise regularly.


After women attain menopause, changes that occur in the body can cause an overactive bladder. During menopause, estrogen which is an important component of the bladder tissue is lost leading to OAB. Menopause is closely related to aging and both can cause OAB.

Diuretic Medications

Diuretic medications also known as water pills are commonly prescribed for individuals suffering from high blood pressure. When you take these medicines, your body gets rid of water and salt faster which can cause the bladder to full causing urine leakage.
