When you live with Inflammatory Bowel Disease (IBD), you become an expert in knowing life can throw you curveballs at any given moment. Those curveballs are especially worrisome and scary during pregnancy and after you become a mom.

For one IBD mom who wishes to remain anonymous, that curveball came in the form of a rare and dangerous vitamin K deficiency that caused life-threatening complications for both her and her newborn son after delivery. Now, two years later, a published medical case study based on their experience is helping raise awareness of this rare issue, offering hope that future pregnancies in the IBD community might benefit from earlier detection and intervention.

Diagnosed Young, Navigating the Unknown

This mom was diagnosed with Crohn’s disease at age 13, and now at 34, she’s lived with IBD for more than 20 years. Her journey has included numerous medications, including a long stretch on Humira, which she remained on during her pregnancy, and four partial small bowel resections. She’s also undergone several exams under anesthesia due to complications like abscesses and fistulas.

Thankfully, during her pregnancy, her Crohn’s was well-controlled with no active disease, making the post-delivery complications much more shocking.

A Sudden Turn After Delivery

After giving birth to her son (we’ll call him “B”), what should have been a joyful moment quickly turned traumatic.

She spent 16 days in the hospital, including three in the ICU, while her newborn faced a 23-day NICU stay. The cause? A severe, undiagnosed vitamin K deficiency, which led to hemorrhaging in both mom and baby. The medical team was blindsided—none of them expected this.

Understanding Vitamin K Deficiency & IBD

Let’s get one important thing straight first. This situation is not about skipping the vitamin K shot that newborns typically receive. The mom explains:

“It’s imperative that newborns receive a vitamin K shot after they are born to prevent vitamin K deficiency bleeding. The American Academy of Pediatrics recommends that all newborns receive a single dose of vitamin K, because babies are naturally born with very little in their bodies. In our case, my son did get the shot—but because I was unknowingly severely deficient in vitamin K during pregnancy, his vitamin K levels in utero were dangerously low, leading to a brain hemorrhage before he was even born. The bleeding he experienced was similar to what some babies experience when they don’t receive the shot, but in our case, it happened earlier—and was not caused by withholding care. In fact, he needed far more vitamin K after birth to restore safe blood clotting levels.”

This vital distinction can prevent confusion and reinforce just how important that standard vitamin K shot is for all newborns.

What She Wants Other IBD Moms to Know

“Knowing what I know now,” she says, “I want fellow IBD women to understand a few key things about vitamin K deficiency during pregnancy:”

This is rare. Most pregnant people with IBD will never encounter this issue. “I hope that offers peace of mind. But as we all know, knowledge is power—especially when you live with IBD.”

If you’ve had bowel resections or are deficient in other fat-soluble vitamins (like A, D, or E), consider bringing this case study to your GI and OB/Maternal Fetal Medicine (MFM) doctors. Ask about checking vitamin K levels, as well as PT/INR and PTT, which monitor blood clotting.

You can develop a deficiency during pregnancy even if you’ve never had one before. “Outside of pregnancy, I had no clotting issues. But between my history of resections and my baby’s increasing demand for nutrients, my levels dropped—and no one knew.”

Looking Back: What She Wishes Had Been Done

“If we had been monitoring my vitamin K levels, PT/INR, and PTT throughout my pregnancy, we likely would have seen early warning signs,” she says. “These aren’t standard tests, but I hope someday they will be for IBD moms with similar risk factors.”

A Silver Lining in the Study

Despite the trauma, having their experience turned into a published medical case study brought a sense of closure.

“When they told us they wanted to publish it, I felt incredibly validated. This wasn’t just something we lived through—it’s now out in the world to potentially save lives. That’s the best-case scenario for us.”

The comprehensive care team—consisting of her OB, MFM, GI, hematologist, and PCP—remained closely connected throughout the experience. After both mother and baby were stabilized, Ohio State’s hematology team and Nationwide Children’s Hospital worked together to identify the deficiency as the root cause for both patients.

“They didn’t miss anything—they acted on the knowledge they had at the time, and when things went south, they sprang into action. I’ll always be grateful for that.”

“B” Today: A Story of Resilience

Despite a traumatic start, B is now a thriving, happy, and a miraculously healthy two-year-old.

“We were so worried about long-term impacts due to the hemorrhage in his brain, but he is now meeting and exceeding all his developmental milestones. He doesn’t need any additional support. It’s truly a miracle.”

His early care included close monitoring from neurology and the Early Development Clinic at Nationwide Children’s Hospital, along with early intervention specialists. Today, all those appointments are in the rearview mirror.

What About Future Pregnancies?

The reality is that this situation may recur if she decides to grow her family.

“My doctors believe I’d face similar risks, so we would monitor everything very closely: vitamin K levels, PT/INR, PTT and I’d likely receive IV vitamin K infusions throughout pregnancy to stay ahead of any deficiencies.”

Lifting the Tide for Others

After two decades of managing Crohn’s, she knows how isolating chronic illness can be.

“It’s hard. It’s lonely. It’s easy to feel invisible. But finding others who share their stories and who get it has been a game-changer for me. That’s why I’m sharing this now. Even if this specific challenge never affects you (and I truly hope it doesn’t), I hope you feel a sense of solidarity. A rising tide lifts all ships and if sharing our story lifts someone else’s experience just a little, it’s worth every word.”
