Does Pelvic Floor Dysfunction Affect Pregnancy? | Better Health Osteopathy

Pelvic Floor Dysfunction In Pregnancy

Pelvic floor muscles are at risk of becoming weakened both during pregnancy and when a traumatic or prolonged delivery takes place. It is estimated injuries to the levator ani muscle (LAM) which is fundamental in pelvic organ support occur in 13-36% of pregnant women who have a vaginal delivery.

In some cases, this can lead to issues with urinary incontinence (leakage of urine) anal incontinence (leakage of faeces), overactive bladder, painful intercourse, or organ prolapse where the bladder, uterine, or rectum can slip into the vagina. These conditions can occur post-delivery, or some years later.

Too often these conditions are left untreated, as women are too embarrassed to discuss this issue of pelvic floor dysfunction, which can have devastating impacts on their quality of life. Often women think that it is a natural part of pregnancy, when in fact in many instances treatment is available.

Why Do Pelvic Floor Injuries Occur?

Many studies have linked a traumatic birth, instrumental delivery, prolonged second stage of delivery, and increased birth weight with pelvic floor injuries. Research supports the importance of pelvic floor exercises during pregnancy and early post-partum, aiding in a decreased risk of future urinary and faecal incontinence.

Pelvic floor injuries are common and often overlooked, and can be a major risk factor in pelvic organ prolapse. MRI and 3D/4D ultrasound are used to accurately diagnose such trauma, most commonly in the form of a tear of the levator ani muscle.

In recent years, requests for caesarean sections without medical indication have increased, as patients believe that it will reduce the impact of vaginal childbirth on the pelvic floor, and reduce the risk of urinary incontinence. However, given the lack of scientific evidence, the current viewpoint is that a caesarean section (which also carries its own serious risk factors) should not be chosen over a vaginal delivery with the view to specifically preventing pelvic floor dysfunction.

3 Things That Help Prevent Pelvic Floor Injury

While it is difficult to generalise as each person’s circumstances differ, there are some things that can be done to help prevent pelvic floor injuries.

1. Pelvic Floor Exercises

Research supports the importance of pelvic floor exercises during pregnancy and early post-partum, with a decreased risk of pelvic floor injury and therefore a decreased risk of future urinary and faecal incontinence.

It is theorised that when the muscles of the pelvic floor are routinely exercised, they are more able to stretch and contract at the time of birth, which may lead to a lower rate of prolonged second-stage labour, and less impact on the pelvic floor. (See exercises below).

2. Modifying Obstetric Practices

Focus should also be on modifying obstetric practices which predispose women to pelvic floor injury. These factors include: the promotion of spontaneous vaginal births without forced or early pushing, avoidance of instrumental assistance, or use of episiotomy. If assistance is needed, vacuum extraction over forceps delivery is recommended.

Warm compresses to the perineum and perineal massage with a lubricant both antepartum and during delivery could also help. These methods have the potential to reduce perineal damage – by increasing vasodilation to the area, which can help with tissue stretching, increasing muscle relaxation and altering pain perception.

3. Adjusting Delivery Position

In contrast to the traditional position of lying on back with legs in stirrups, upright and side lying birthing positions have been found to be beneficial.

Shorter second-stage delivery times, the reduction in the need for instrumental intervention, fewer episiotomies and reduced muscle tearing are just some of the benefits to altering delivery positions.

Treatment Of Pelvic Floor Dysfunction

Pelvic floor dysfunction can most definitely be treated. Treatments normally include a combination of physical therapy, lifestyle changes, treatment of underlying medical issues, relaxation techniques, and hormone treatment. For more serious dysfunction such as prolapses, the use of pessaries (non-surgical) and reconstructive surgery is common.

The best treatment however is prevention – it is important that women of all ages learn how to strengthen their pelvic floor muscles. This preparation will assist women during child birth and also post menopause where oestrogen levels drop which can lead to further weakening of the pelvic floor muscles, leaving women at a greater risk of urinary incontinence and prolapse.

How Can Osteopathy Help Me Strengthen My Pelvic Floor?

During pregnancy Osteopathic treatment will address any strains and dysfunction in your spine and pelvis, to ensure that the pelvic bones and muscles are aligned and balanced, providing optimum conditions for positioning, descent, and passage of the baby through the birth canal during delivery.

Post-delivery Osteopathic treatment will focus on any strains and trauma that may have occurred during labour and work to re-align your pelvis and spine. A well aligned pelvis can provide the optimum environment for the pelvic floor muscles to heal. Throughout labour and post-pregnancy we teach strengthening exercises of the pelvic floor and gentle core exercises to strengthen the body during these demanding times.
