Why overactive bladder is so common in people with diabetes

Overactive bladder is a condition that many people find embarrassing or difficult to talk about, yet it affects millions of adults around the world.

People with overactive bladder often feel a sudden and strong need to urinate, may go to the bathroom very often during the day and night, and sometimes experience urine leakage.

These symptoms can disrupt sleep, limit social activities, and reduce quality of life. New research now shows that this problem is especially common among people living with diabetes.

A recent scientific review published in the journal Neurology and Urodynamics brings new attention to this issue. The study shows that adults with diabetes are much more likely to develop overactive bladder than people without diabetes.

This finding is important because diabetes already places a heavy burden on daily life, and bladder problems can make managing the disease even more challenging.

Diabetes affects how the body handles sugar in the blood. Over time, high blood sugar can damage blood vessels and nerves throughout the body. This damage does not only affect the heart, eyes, or kidneys.

It can also affect the nerves that control the bladder. When these nerves are damaged, the bladder may become overly sensitive or unable to hold urine properly, leading to overactive bladder symptoms.

To better understand how common overactive bladder is in people with diabetes, researchers from Shaoxing People’s Hospital in China reviewed past studies on this topic. Led by Xiaolong Zhang, the research team examined results from 14 studies published between 2010 and 2024.

Together, these studies included more than 82,000 adults with diabetes, making this one of the largest reviews ever done on this issue.

The results were striking. The researchers found that about 30 percent of adults with diabetes have overactive bladder. This means nearly one in three people with diabetes may experience bladder problems.

Even more concerning, people with diabetes were more than three times as likely to have overactive bladder compared with people without diabetes. This shows that diabetes is a major risk factor for bladder control problems.

The study also identified several factors that increase the risk of overactive bladder in people with diabetes. Age played an important role, with older adults facing higher risk. This is not surprising, as both diabetes complications and bladder problems become more common with age.

The length of time a person has had diabetes also mattered. People who had lived with diabetes for many years were more likely to develop overactive bladder, suggesting that long-term damage from high blood sugar plays a key role.

High blood pressure was another strong risk factor. Many people with diabetes also have hypertension, and this combination may further damage blood vessels and nerves, including those that support normal bladder function. The strongest link, however, was seen with diabetic neuropathy.

Neuropathy is nerve damage caused by diabetes and often leads to numbness, pain, or weakness in the hands and feet. This study shows that when diabetes damages nerves, it can also affect the bladder, making overactive bladder much more likely.

These findings matter for both patients and healthcare providers. Overactive bladder is often underreported because people may feel ashamed or think symptoms are a normal part of aging.

This study makes it clear that bladder symptoms in people with diabetes should not be ignored. They may be a sign of underlying nerve damage or poor blood sugar control.

From a public health point of view, this research highlights the need for early screening and prevention. Doctors treating people with diabetes should ask about bladder symptoms, especially in older patients, those with long-standing diabetes, high blood pressure, or nerve problems. Early treatment may help reduce symptoms and improve quality of life.

When reviewing and analyzing these findings, it becomes clear that overactive bladder is not just a separate problem but part of the broader impact of diabetes on the body.

The study strengthens the idea that good diabetes management is essential not only for preventing heart disease and kidney failure but also for protecting bladder health. Keeping blood sugar and blood pressure under control may help reduce the risk of bladder problems over time.

The large number of patients included in this review adds strength to the results, but it is also important to note that most of the studies were observational. This means they can show strong links but cannot fully prove cause and effect.

Still, the consistency of the findings across many studies suggests that the connection between diabetes and overactive bladder is real and significant.

Overall, this research sends a clear message. Overactive bladder is common in people with diabetes, and certain groups are at especially high risk. Recognizing this early can lead to better care, fewer complications, and improved daily life for millions of people living with diabetes.
