Pregnancy and EDS: What Nobody Told Me Before I Got Pregnant
Why Pregnancy Is Different With EDS
Pregnancy affects connective tissue in every woman. The body produces a hormone called relaxin during pregnancy, which loosens ligaments and joints to prepare for childbirth. In a typical pregnancy this is controlled and temporary. In EDS, where connective tissue is already structurally different, the effect of relaxin can be significantly amplified and harder to reverse — setting off a cascade of complications that can persist and worsen for decades.
The Hip Cascade — A Two-Decade Story
In EDS specifically, pregnancy can trigger structural changes that initiate a long-term cascade. Pelvic misalignment during pregnancy, when connective tissue is at its most lax, can alter load distribution through the hip joints in ways that drive progressive arthritis. Over years and decades, what began as postpartum instability can progress to serious structural damage.
Protrusio acetabuli — a condition in which the hip socket migrates further into the pelvic cavity than normal — is one such progression. Sacroiliac joint instability and pubic symphysis dysfunction can accompany it. Eventually, bone spur formation and mechanical locking of the joint may make normal function impossible and surgery unavoidable.
Medical Misattribution — When EDS Pain Gets the Wrong Label
One of the most significant risks for people with undiagnosed or poorly understood EDS is having their pain misattributed to other causes. Pelvic and hip pain in women is frequently investigated through a gynecological lens — and when an ovarian cyst is found, it becomes the convenient explanation even when it may not be the actual source of pain.
For people with EDS, pelvic pain is often driven by connective tissue instability — the sacroiliac joints, the pubic symphysis, the hip capsule. These structural sources of pain can persist or worsen after gynecological interventions because the actual cause was never addressed. Procedures performed based on misattribution cannot resolve pain they didn't cause.
Postpartum Challenges — The Period Nobody Talks About
The postpartum period can be equally or more challenging than pregnancy itself. The hormonal shift after delivery is rapid and dramatic, and for people with EDS the connective tissue loosening does not always normalize quickly. Pelvic floor dysfunction, continued joint instability, and fatigue are common. Wound healing may also be significantly affected — particularly in classical EDS where MCAS compounds the impairment of tissue and nerve regeneration.
The psychological dimension of postpartum complications in EDS deserves acknowledgment. When physical limitations prevent a new mother from caring for her baby in the ways she expected — holding, feeding, basic caregiving tasks — the impact on bonding and mental health can be profound. Postpartum depression in this context is not simply a hormonal event. It is a response to physical incapacity, loss of expectation, and the devastating combination of a body that isn't working and a system that doesn't understand why.
Over the following two decades my hip arthritis progressed dramatically. What began as postpartum misalignment became protrusio acetabuli — my hip socket moved further into my pelvic cavity. SIJ instability and pubic dysfunction followed. A bone spur grew almost as large as the ball of the hip joint itself, eventually causing the joint to lock completely. Surgery became unavoidable.
Along the way, pain that was EDS-driven pelvic instability was attributed to an ovarian cyst. My left ovary was removed. In retrospect, that surgery was unnecessary — the pain had nothing to do with my ovary. It was EDS the whole time.
