Incontinence: A Muscle Problem Or Something More?

is incontinence a muscle problem

Incontinence is the loss of bladder control, which causes uncontrollable urine leakage. It is more common in women and the elderly. Incontinence can be caused by weakened pelvic floor muscles, which can occur due to muscle loss, especially in older individuals. Weakened pelvic floor muscles can lead to a lack of support for internal organs, resulting in difficulty controlling the release of urine. To treat incontinence, pelvic floor exercises can be effective in strengthening these muscles and reducing leaks. Additionally, certain medications can help by stabilizing muscle contractions or relaxing muscles to empty the bladder completely.

Weak pelvic floor muscles

Pelvic floor muscles can weaken over time due to various factors, such as injury, pregnancy, childbirth, prostate cancer treatment, obesity, and the ageing process. Certain conditions like diabetes may also contribute to muscle weakness. Additionally, high-impact exercises, smoking, and lifting heavy objects can put extra strain on the pelvic floor, increasing the likelihood of leaks.

To strengthen the pelvic floor muscles and alleviate incontinence symptoms, specific exercises, such as Kegels or pelvic floor exercises, can be performed. These exercises involve squeezing and relaxing the pelvic floor muscles to improve muscle tone and enhance brain connections to these muscles. It is important to do these exercises correctly, including both short and long squeezes, without engaging the abdomen, buttocks, or thighs.

Other treatments for incontinence due to weak pelvic floor muscles include physical therapy, medical devices like a vaginal pessary, and, in severe cases, reconstructive surgery to secure the pelvic organs. Lifestyle changes, such as losing excess weight and switching to low-impact exercises like Pilates, can also help reduce symptoms.

Bladder and bowel control

Bladder incontinence can be caused by changes in food or drink, constipation, or an overactive bladder. Increasing fibre and fluid intake can help manage these issues. Pelvic floor exercises, such as Kegel exercises, can strengthen the pelvic floor and sphincter muscles, improving bladder control. For those who smoke, coughs can put strain on the pelvic floor muscles, so quitting smoking may help. High-impact exercises and sit-ups can also increase leaks, so replacing them with strengthening exercises like pilates is recommended. Being overweight can also weaken the pelvic floor muscles, so losing excess weight may relieve symptoms.

Bowel incontinence can be caused by weaker muscles around the bottom, which can be a result of ageing, hormonal changes, or childbirth. It can also be caused by health conditions affecting the digestive system, such as constipation, irritable bowel syndrome (IBS), or Crohn's disease. Additionally, certain health conditions can make individuals less aware of when they need to defecate, such as dementia, learning disabilities, stroke, or nerve damage in the spine.

Treatments for bladder and bowel incontinence can range from dietary changes, exercises, and medications to electrical stimulation and surgery. It is important to talk to a healthcare provider about these issues, as they can help manage and treat the problem.

Pelvic floor exercises

Incontinence is the loss of bladder control, which often leads to uncontrollable urine leakage. It is more common in females and people over 50. Pelvic floor exercises can be an effective way of reducing leaks associated with incontinence. These exercises help to strengthen the pelvic floor muscles, which support the bladder and prevent leakage.

To perform pelvic floor exercises, it is important to first identify the correct muscles. One way to do this is to try to imagine stopping yourself from urinating and passing gas. Once you have identified these muscles, you can start with quick squeezes. Squeeze your pelvic floor muscles without pulling in your tummy, hold the squeeze for 2 seconds, and then relax. Repeat this 10 times. It is important to breathe normally and relax while doing these exercises.

Gradually work your way up to longer squeezes, aiming for 10 seconds each. You can also incorporate different types of exercises to strengthen your pelvic floor, such as pilates, which is a form of strengthening exercise that benefits stress incontinence. The bird-dog exercise is another example that activates multiple muscle groups, including the pelvic floor. To perform this exercise, start on your hands and knees, keeping your back straight and engaging your core muscles. Simultaneously extend and raise your left leg and right arm, holding this position for a few seconds.

Pelvic tilts are another effective exercise to strengthen the lower back and abdominal muscles, contributing to pelvic floor stability. Lie on your back with your knees bent and feet flat on the floor. Tighten your abdominal muscles and press your lower back into the floor, holding this position for a few seconds before releasing. Repeat this movement 10-15 times, increasing the number of repetitions as your muscles get stronger. Consistency is key when it comes to pelvic floor exercises, so aim to perform these exercises 2-3 times a week for optimal results.

Muscle mass loss

Urinary incontinence is the loss of bladder control, which causes uncontrollable pee leakage. It is more common in females and people over 50. While incontinence is not exclusively a muscle problem, muscle mass loss can be a contributing factor.

A study on elderly Korean women found no association between urinary incontinence and appendicular, truncal, and total muscle loss. However, other studies have shown that a higher percentage of lean muscle mass in women is associated with lower odds of stress incontinence. Similarly, a 5% or greater decrease in grip strength was associated with a 60% higher likelihood of developing or continuing to experience stress incontinence.

The pelvic floor muscles play a crucial role in bladder control. When these muscles are weak, they can lead to leaks during activities such as coughing, sneezing, or exercising. Pelvic floor exercises can help strengthen these muscles and reduce leaks. Additionally, maintaining a healthy weight is important, as obesity can put extra pressure on the bladder and worsen incontinence.

To summarise, while muscle mass loss alone may not be the sole cause of incontinence, having stronger muscles and maintaining a healthy weight can help reduce the risk and improve symptoms of stress urinary incontinence. Further research is needed to fully understand the relationship between muscle mass loss and incontinence, especially considering the aging population in countries like Korea.

Detrusor muscle dysfunction

Incontinence is the loss of bladder control, which leads to uncontrollable urine leakage. It is more common in females and people over 50. While incontinence can be caused by a variety of factors, one of the causes is detrusor muscle dysfunction.

The detrusor muscle is the primary muscle of the bladder, forming its walls. It is under autonomic control, specifically the parasympathetic nervous system, which stimulates the bladder through the pelvic nerve fibres. When the bladder is filled with urine, the M3 receptors in the bladder are stretched and stimulated, leading to the contraction of the detrusor muscle for urination. Simultaneously, the parasympathetic fibres inhibit the internal urethral sphincter, causing it to relax and allowing the bladder to empty.

Detrusor muscle pathology or dysfunction can lead to urinary retention, incontinence, or both. Detrusor underactivity, or an underactive bladder, is characterised by a contraction of reduced strength and/or duration, resulting in slow or incomplete bladder emptying. This can be caused by myogenic factors, i.e., problems with the detrusor muscle itself, or neurogenic factors, i.e., injuries to the nerves supplying the bladder. Neurogenic detrusor overactivity, previously known as hyperreflexia, is a neurological condition causing involuntary contractions of the detrusor muscle, leading to urinary incontinence. It can be caused by damage or disruption to the nerves supplying the detrusor muscle, which may be due to a more serious neurological condition such as multiple sclerosis, stroke, or spinal cord injury.

Physiotherapy can be an effective treatment for neurogenic detrusor overactivity, helping to retrain the bladder and reduce symptoms. Additionally, there are medications that can help with an overactive bladder, such as beta-3 agonists, which utilise the adenylyl cyclase-cAMP pathway to treat bladder overactivity. For an underactive bladder, there is currently no drug that consistently improves the bladder muscle's contraction. However, timed voiding, or peeing according to a schedule, can be a helpful technique to manage an underactive bladder.
