PELVIC FLOOR DYSFUNCTION: SYMPTOMS, CAUSES AND TREATMENT

Your pelvic floor is part of your core foundation, helping you stay stable, supported and in control. But over time, factors such as pregnancy, ageing, hormonal changes and even long hours of sitting (a common part of life in Singapore) can weaken these muscles. When the pelvic floor loses its strength or coordination, it may lead to bladder leaks, pelvic discomfort or difficulty with bowel control.

The good news is that with proper diagnosis and evidence-based treatments, pelvic floor dysfunction can be effectively treated and managed. Understanding the symptoms, causes and treatment options is the first step toward restoring strength and confidence in your daily life.

What Is Pelvic Floor Dysfunction?

Pelvic floor dysfunction (PFD) occurs when the muscles, ligaments and connective tissues that support your bladder, uterus (or prostate) and bowel are unable to coordinate and function properly. Instead of contracting and relaxing in harmony, these muscles may become too weak, too tight or fail to activate at the right time. This imbalance can lead to problems such as urinary or bowel leakage, pelvic pain or discomfort during physical activity or sexual intercourse.

What Are the Symptoms of Pelvic Floor Dysfunction?

Pelvic floor dysfunction can show up in different ways depending on which muscles are affected and how severe the condition is. Some people experience discomfort or inconvenience, while others may notice more significant changes in bladder, bowel or sexual function. Common symptoms include:

• Urinary issues such as leaking, difficulty starting urination or feeling like the bladder doesn’t fully empty.
• Bowel problems including constipation, straining or involuntary leakage.
• Pelvic pain or pressure, especially when sitting, standing for long periods or during physical activity.
• Pain or discomfort during sexual intercourse (for both men and women).
• A feeling of heaviness or bulging in the pelvic area, which may indicate pelvic organ prolapse.
• Lower back, hip or groin pain that doesn’t seem linked to posture or movement alone.

What Are the Causes and Risk Factors of Pelvic Floor Dysfunction?

Pelvic floor dysfunction can develop from a combination of lifestyle habits, physical strain and natural changes that occur throughout a woman’s life. Over time, these factors can weaken or tighten the pelvic muscles, affecting how well they support the bladder, uterus and bowel.

Common causes and contributing factors include:

• Pregnancy, Childbirth and Gynaecological Surgery

  Pregnancy and delivery place significant pressure on the pelvic floor, especially during prolonged or difficult labour. Similarly, previous surgeries involving the uterus, bladder or anal region (such as a hysterectomy) can affect muscle strength or nerve control.

• Muscle and Nerve-Related Factors

  Injury or trauma to the pelvic area (e.g., from a fall or accident) can damage the muscles or nerves that control pelvic function. Neurological conditions, such as multiple sclerosis or spinal cord injury, may also interfere with muscle coordination.

• Chronic Strain and Overuse

  Repeated straining during bowel movements, chronic coughing or overuse of the pelvic muscles can lead to fatigue and dysfunction. Conditions such as constipation, inflammatory bowel disease (IBD) or irritable bowel syndrome (IBS) can contribute to excessive pelvic strain.

• Ageing and Connective Tissue Changes

  As women age, the natural decline in muscle mass and elasticity, together with lower oestrogen levels after menopause, can weaken the pelvic floor. Some women may also have connective tissue disorders that make them more prone to pelvic organ prolapse or muscle laxity.

• Lifestyle Factors

  Prolonged sitting, obesity and a sedentary lifestyle increase pressure on the pelvic floor. High levels of stress or anxiety can cause chronic muscle tension, affecting the ability of the pelvic muscles to relax and function normally.

How Is Pelvic Floor Dysfunction Diagnosed?

Because pelvic floor dysfunction can affect multiple organs and systems, an accurate diagnosis involves a thorough assessment of your symptoms, medical history and pelvic muscle function. These evaluations help identify the underlying cause and guide the most effective treatment plan.

• Medical History Assessment

  Your doctor will begin by discussing your symptoms, including when they started, how severe they are and what may trigger or relieve them. A detailed obstetric and gynaecological history covering pregnancies, deliveries and any complications during labour also provides important insights into possible contributing factors.

• Pelvic Examination

  A physical exam allows the doctor to assess the strength, tone and coordination of the pelvic floor muscles. This may include a visual inspection and gentle internal palpation to detect muscle weakness, tension, pain or signs of pelvic organ prolapse.

• Urodynamic Studies

  This test measures how well the bladder and urethra are working. During the procedure, sterile water is introduced into the bladder through a thin catheter while bladder and abdominal pressures are monitored. The results help identify issues such as bladder overactivity or incomplete emptying related to pelvic floor dysfunction.

• Electromyography (EMG)

  EMG testing evaluates the electrical activity of the pelvic floor muscles to assess how well they contract and relax. Surface electrodes are placed around the vaginal or anal area or fine needle electrodes may be used for more precise readings. This helps detect muscle weakness, overactivity or poor coordination.

• Imaging Tests

  Ultrasound and magnetic resonance imaging (MRI) can provide detailed images of the pelvic structures. In some cases, a specialised X-ray called defaecography may be performed while passing stool to evaluate how the pelvic floor muscles move and to identify structural changes such as rectoceles or prolapse.

What Are the Treatment Options for Pelvic Floor Dysfunction?

Treatment for pelvic floor dysfunction requires a personalised approach that addresses the individual's specific symptoms and severity. The treatment strategy typically begins with conservative approaches and may progress to more invasive interventions if symptoms persist or worsen.

Frequently Asked Questions About Pelvic Floor Dysfunction

• Is pelvic floor dysfunction reversible?

  In many cases, pelvic floor dysfunction can be significantly improved or effectively managed with proper treatment. The extent of recovery depends on the underlying cause and severity of the condition, but early diagnosis and intervention often lead to the best outcomes.

• How long does it take to recover after pelvic floor dysfunction treatment?

  Recovery time depends on the type of treatment. Conservative methods, such as physiotherapy and lifestyle changes, may show improvement within a few weeks to a few months. For surgical treatments, recovery usually takes around 6 to 12 weeks, depending on the specific procedure and individual healing response.

• Can pregnancy worsen pelvic floor dysfunction?

  Yes. Pregnancy can worsen pelvic floor dysfunction as the growing uterus increases pressure on the pelvic muscles, while hormonal changes reduce muscle strength and elasticity. Women with existing pelvic floor issues should work closely with their healthcare provider during pregnancy to manage symptoms and minimise further strain.

• Could my symptoms be caused by pelvic floor dysfunction or something else?

  Pelvic floor dysfunction can resemble other conditions such as urinary tract infections, irritable bowel syndrome or endometriosis. Because symptoms often overlap, it’s best to see a gynaecologist for a proper assessment. They can identify the underlying cause and recommend the most appropriate treatment.
