MS: When the bladder malfunctions - A symptom that isn't discussed enough

MS: A disease that disrupts nerve communication

Multiple sclerosis is an autoimmune disease that affects the central nervous system, specifically the brain and spinal cord.

It causes lesions that disrupt the transmission of nerve signals. These messages are essential for coordinating many bodily functions, including those we do not consciously control, such as bladder function.

When these signals are disrupted, the information exchange between the brain and the bladder becomes less reliable. This can lead to a delay between when the bladder is full and when the brain becomes aware of it, or to difficulty coordinating the muscles needed for urination.

Why is the bladder affected in MS?

Bladder function relies on a precise balance between several nervous and muscular mechanisms.

Under normal circumstances, the bladder fills gradually without triggering an immediate urge. When the volume becomes sufficient, a signal is sent to the brain, which decides the appropriate time to urinate. This process requires precise coordination between the nerves, the bladder muscles, and the sphincters.

In MS, lesions can disrupt this coordination. The bladder may then contract too early, not contract enough, or function unpredictably. This disruption explains the variety of symptoms observed.

A variety of symptoms, sometimes difficult to identify

An “overactive” bladder

In some people, the bladder becomes overactive. It sends frequent signals of the urge to urinate, sometimes even when the volume is low.

These urges can be sudden, difficult to delay, and sometimes associated with leakage. This can create anticipatory anxiety, particularly in situations where access to a toilet is not immediate.

A bladder that does not empty properly

Conversely, some people have difficulty completely emptying their bladder.

This can result in a sensation of retention, a prolonged urge to urinate, or the need to return to the toilet shortly afterward. This situation can be uncomfortable and sometimes a source of concern.

A combination of both

In some cases, these two types of disorders can coexist.

The bladder may both contract inappropriately and fail to empty effectively. This combination makes the symptoms harder to anticipate and manage on a daily basis.

A real impact on daily life

Constant adjustments

Urinary problems can force patients to constantly adjust their daily routines.

Leaving the house often involves locating toilets in advance, limiting certain beverages, or planning trips around these constraints. This constant vigilance can be exhausting in the long run.

A negative impact on quality of life

Beyond the practical aspects, these symptoms can have a significant emotional impact.

The fear of the unexpected, the stares of others, or the feeling of losing control can affect self-confidence. Some people may avoid certain social or professional situations, which can lead to gradual isolation.

A topic that remains taboo

A reluctance to talk about it

Urinary disorders touch on an intimate sphere, often associated with modesty.

Even when they are common, they remain difficult to discuss. This discomfort can be exacerbated by the fear of being judged or misunderstood.

A lack of visibility

Because they are invisible, these symptoms are often less recognised than other manifestations of MS.

They may be downplayed or even ignored, even though they have a tangible, day-to-day impact. This invisibility helps perpetuate the stigma.

The link to emotions

Bladder function is also influenced by the autonomic nervous system, which is sensitive to stress and emotions.

In certain situations, stress can intensify urgent urges or make symptoms harder to manage.

Conversely, living with these issues can generate emotional tension, creating a cycle where symptoms and emotions influence each other.

Why it’s important to talk about it

Addressing these symptoms allows them to be recognised as part of the disease.

It can also help in better understanding how they work and alleviate some of the feeling of isolation. Knowing that these issues are common in MS can already be a relief for some patients.

Living with it: finding your bearings

Over time, patients often develop a better understanding of their bodies and their rhythms.

They learn to identify risky situations, adapt their habits, and anticipate certain times of the day.

These adjustments, though sometimes restrictive, gradually allow them to regain a certain balance and live better with these symptoms.
