Expecting and experiencing pelvic pain? It could be symphysis pubis dysfunction. Here's what you need to know about this uncomfortable pregnancy condition, including potential risks and treatments.

What is symphysis pubis dysfunction?

Symphysis pubis dysfunction (SPD), or pelvic girdle pain (PGP), happens when the ligaments that normally keep your pelvic bone aligned during pregnancy become too relaxed and stretchy too soon before birth (as delivery nears, things are supposed to start loosening up). This, in turn, can make the pelvic joint — a.k.a. the symphysis pubis — unstable, causing some pretty strange sensations, including pelvic pain.

How common is SPD in pregnancy?

The incidence of diagnosed SPD is about 1 in 300 pregnancies, though some experts think that up to 25 percent of all pregnant women will experience SPD (though not all have it diagnosed).

What are the signs and symptoms of SPD?

The most common symptoms are difficulty when walking and wrenching pain (as though your pelvis is tearing apart). Typically, the pain is focused on the pubic area, but in some women it radiates to the upper thighs and perineum.

The pain can worsen when you're walking and doing weight-bearing activities, particularly those that involves lifting one leg like climbing stairs, getting dressed, getting in and out of a car, or even turning over in bed.

What causes symphysis pubis dysfunction?

The culprit behind SPD is the aptly named hormone relaxin, which makes your ligaments stretchy so your baby can ease his way into the world. Sometimes relaxin does its job too well, loosening the ligaments around your pelvic bone way before baby is ready to come out, which causes instability (and unfortunately, pain) in the pelvic joint.

What you need to know about SPD

In very rare cases, the joint may gape apart, a condition called diastasis symphysis pubis or symphyseal separation, which can cause more serious pain in your pelvis, groin, hips and buttocks.

Very rarely, SPD can rule out a vaginal delivery, and your practitioner may opt for a C-section instead. And in even rarer cases, SPD can worsen after delivery, requiring medical intervention. But for most moms, once your baby is born and relaxin production ceases, your ligaments (and dance moves) will return to normal.
