Weighting and Expecting: Pelvic Girdle Pain During Pregnancy

Pregnancy is full of joy, wonder, and excitement. While it’s a beautiful journey, it’s common to experience challenges like exhaustion, anxiety, and pain. Let’s talk about one of the physical changes you may experience as a mum-to-be — Pelvic Girdle Pain (PGP), more specifically related to your pregnancy.


Pregnancy-related pelvic girdle pain (PrPGP) is defined as any pain between the iliac crests and the gluteal fold, particularly in the vicinity of the sacroiliac joints. The pain can radiate down the posterior thigh and may also occur in conjunction with or separately in the pubic symphysis. The endurance capacity for standing, walking, and sitting is diminished (Vleeming et al. 2008). Up to 50% of women will experience PrPGP, and it is strongly associated with a negative impact on psychological and emotional well-being (Acharya et al. 2019). Unfortunately, women with PrPGP are three times more likely to experience postpartum depressive symptoms (Gutke et al. 2007).


Women experiencing PrPGP may describe a sharp stabbing pain, and their leg may feel like it could give way. Some may also report a grinding or clicking sensation in the affected area. The following tasks aggravate their symptoms:

  • Turning over in bed
  • The first few steps in the morning
  • Getting in and out of the car
  • Climbing stairs
  • Getting dressed


It’s more than an issue in the tissues…

1. Hormonal

The increased levels of relaxin, progesterone, and oestrogen during pregnancy work together to soften the strong ligaments surrounding the pelvis. These ligaments absorb more water and become more elastic, allowing the pelvis to open up during childbirth to create space. Relaxin starts to peak at 10-12 weeks gestation, which may contribute to the early onset of PrPGP, but this hormonal influence does not make the pelvis unstable.

2. Biomechanics and load

Pregnancy is a phase of big change. Muscles and fascia, including the abdominal wall and linea alba (diastasis), undergo increased stretching. The pelvic floor muscles are also affected. Changes in posture are necessary to accommodate the growing foetus. These combined alterations contribute to the “pregnancy wobble” that some individuals may experience.

3. Poor movement patterns

During pregnancy, you may load your pelvis asymmetrically—such as when holding a toddler or carrying a heavy handbag on one arm. This can result in an asymmetry between the pelvis. No two sides are the same, but pregnancy introduces a unique dynamic where one side becomes stiffer and the other more mobile with each step you take.

4. The pregnancy factor

The Palsson et al. (2015) study showed that pregnant women experienced lower pain sensitivity thresholds compared to non-pregnant women. This phenomenon was attributed to the physical transformations, as well as changes in emotional well-being.


  • Previous history of lower back pain
  • Previous PGP
  • History of trauma such as fall, motor vehicle accident or sports injury
  • BMI > 25
  • Strenuous work during pregnancy
  • Depression
  • Hypermobile joints (no evidence for this one)
  • Multiparity (no evidence for this one either)


A study by Owe et al (2015) found that women who performed high-impact exercise three times a week were 14% less likely to suffer from severe PrPGP. Addressing other factors such as reducing BMI, improving mental health, and providing education to empower women may also have a positive impact.


Research indicates that up to 50% of women with PGP often report changes to their bladder, bowel, or sexual function. Pregnancy-related weight gain can lead to the stretching of pelvic floor muscles and sphincter relaxation, resulting in weakness. This may cause stress urinary incontinence. However, women with PrPGP often present with increased pelvic floor muscle tone (overactivity), so traditional pelvic floor exercises may not always be suitable.


There is a greater than 90% chance that you will be better in the postnatal period, and the “strongest predictor of PrPGP not becoming chronic after pregnancy is the belief that it won’t” (Vollestad and Stuge 2009).


“It is no longer acceptable to consider musculoskeletal pain solely as a peripheral phenomenon” (Pool-Goudzwaard et al 2020). Addressing the following factors is crucial to achieve your goals:

  • Biological: Hormones, central and/or peripheral sensitization, neuro-immune response, inflammation
  • Psychological: Sleep, stress, depression/anxiety, beliefs, active vs. passive coping strategies
  • Social: Work support, family support, life transitions, relationshipsThere is so much you can do, but the first step is education and understanding what is going on with your pelvis.


Here are some take-home points from today’s blog:

Schedule an appointment with a women’s health physiotherapist for an individual assessment and physiotherapy treatment, considering symmetry, biomechanics, and motor control.

Exercise is beneficial for all women, regardless of pain, to provide support for the pelvis. Focus on strengthening the glutes, pelvic floor, and deep core muscles. After the pain settles, continue exercising to maintain optimal muscle function and prevent future issues.

I had a great experience at Embrace physiotherapy with Dr Preet. I started my journey the last trimester of my pregnancy to assess my pelvic floor strength and relaxation level. Dr Preet helped me go through until the end of my pregnancy with exercise plan for the pelvic floor, my hips and quads. My delivery went very smoothly and I am lucky to not have tear or abs separation. I went back after delivery to strengthen back my pelvic floor and got discharge with the chance to fully get back to my usual sport practice. Dr Preet has been wonderful. She listens to your needs carefully and take the time to evaluate your body range of movement. It was also nice to feel understood and share experience as a new mother.
