Short Bowel Syndrome: The Complication Many IBD Patients May Not See Coming

For someone living with Crohn’s disease, surgery can feel like a necessary reset button. The diseased portion of your intestine is removed, you recover, and you hope your body and your life will settle into a new normal.

But what happens when too much intestine is removed, or the remaining intestine can no longer absorb what your body needs?

That’s where short bowel syndrome (SBS) comes in.

SBS occurs when the small intestine is too short or isn’t functioning well enough to adequately absorb the fluids, electrolytes, nutrients, and calories the body needs. For people with Crohn’s disease who have undergone multiple intestinal surgeries, SBS is a potential complication that deserves more attention.

When 18 inches of my small intestine were removed in 2015, SBS was never mentioned as something I might need to think about if future surgeries became necessary. And that got me wondering: How many other people living with IBD aren’t aware of this?

This week on Lights, Camera, Crohn’s, we’re taking a closer look at SBS: what it means for people with IBD, how it can affect quality of life, what treatment options are available, and what patients and caregivers should know so they can recognize the signs and advocate for the care they need.

What exactly is short bowel syndrome?

The small intestine plays a huge role in keeping us nourished and hydrated. It absorbs nutrients from the foods and liquids we consume and helps our bodies get the building blocks they need to function. When someone has SBS, there isn’t enough functional small intestine to adequately perform that job.

SBS can develop after surgical removal of the small intestine because of conditions including Crohn’s disease, other forms of IBD, cancer, blood clots, or traumatic injury. It can also occur in people who are born with a shortened or incompletely developed small intestine.

According to the Short Bowel Foundation, SBS is a rare condition affecting 20,000 people in the United States.

Much like IBD, A person with SBS may look completely healthy on the outside while dealing with fatigue, abdominal symptoms, frequent bathroom trips, diarrhea, difficulty maintaining weight and ongoing challenges with hydration and nutrition.

Dr. Sukanya Subramanian, MD, Medstar Georgetown University Hospital, is a small bowel adult transplant gastroenterologist and specializes in intestinal rehab. She says diagnosing SBS can be a challenge.

“For example, Crohn’s disease is much more recognizable with endoscopic, microscopic, and laboratory criteria. There isn’t an absolute unequivocal test that tells you that you do or don’t have short bowel syndrome. Sometimes people are in the ambiguous zone, and we have to estimate length of bowel, do testing of absorptive capacity, evaluate transit times of food through the remaining intestine and consider this in the context of symptoms and lab data to make inferences about the diagnosis.”

Short bowel doesn’t automatically mean short bowel syndrome

There isn’t a simple blood test, scan or single diagnostic test that says, You have SBS.

Short bowel is described as having fewer than approximately 180–200 centimeters of small intestine, but the number alone doesn’t tell the whole story.

Think about it this way: two people could have the same amount of intestine remaining but have very different experiences.

The amount of bowel someone started with can vary. A smaller person may naturally have less intestine than a much taller person. And someone may technically have more than 200 centimeters of intestine remaining but still experience significant problems if their bowel isn’t functioning properly.

That’s why length isn’t the only consideration. Function matters.

Healthcare providers need to consider whether the remaining intestine can absorb enough fluid, electrolytes, and nutrients to maintain adequate hydration and nutrition.

SBS should be on the radar for someone with a history of intestinal surgery who is experiencing ongoing loose stools, difficulty maintaining weight or challenges staying adequately hydrated.

Why Crohn’s patients should know about SBS

Life with Crohn’s is unpredictable and ongoing inflammation, strictures, fistulas, obstructions, and other complications can lead to surgery. While removing diseased bowel can be lifesaving and dramatically improves someone’s quality of life, every intestinal surgery can change the anatomy and function of the digestive system. For example, if someone has their ileum removed, they become vulnerable to fat malabsorption, meaning that bile salts can’t be recycled to the liver.

For patients who have had multiple resections, it’s important to understand that there can be consequences beyond the recovery period.

The question isn’t simply, “How much intestine do I have left?” It’s, “How well is the intestine I have left working?”

Dr. Subramanian says, “Length of remnant bowel is not the sole determining factor in the diagnosis of SBS. The quality of the remaining bowel is very important. Intestinal ischemia, active Crohn’s disease, Crohn’s fibrosis, and intestinal dysmotility are co-existing conditions that can impact the capacity of the bowel.”

This is a conversation worth having with your gastroenterologist, particularly if you’re experiencing persistent diarrhea, dehydration, nutritional deficiencies, or difficulty maintaining your weight after intestinal surgery.

Treatment starts with nutrition and hydration

When someone is first diagnosed with SBS, the immediate priority is getting the patient out of crisis and stabilized.

That can sometimes mean an escalation of care to make sure the person receives the fluids, electrolytes, and nutrition they need. Once someone is stable, the goal is to gradually optimize their intestinal absorption, and when possible, dial back the level of parenteral or intravenous support required.

“Dietary modifications are crucial to achieving enteral autonomy and far too often are treated as an afterthought during a clinical visit, explains Dr. Subramanian. “The dietary recommendation for each patient depends on their anatomy, mainly whether there is a colon present and if it is in continuity with the rest of the bowel. It is important that each patient with SBS work with their local care team to identify and address their unique needs.”

Some people can meet their nutritional needs by eating and drinking by mouth. Others may require nutritional support through a vein, known as parenteral nutrition.

Someone with SBS may assume that drinking more plain water is the obvious solution to frequent diarrhea or dehydration. But depending on the individual, simply increasing water intake may actually make symptoms worse.

That’s why some patients may need oral rehydration solutions specifically designed to help the body absorb fluids and electrolytes more effectively.

There is no “perfect SBS diet”

Nutrition counseling for SBS should be individualized and physician and patient priorities should be aligned.

A healthcare provider may consider:

  • What foods is the person eating now?
  • What foods do they tolerate?
  • What foods are important to them? Are there cultural considerations?
  • What are their nutritional needs?
  • What are their symptoms?
  • What changes are realistic?
  • What are the patient’s non-negotiables?

A treatment plan that completely ignores quality of life may look perfect on paper but may be challenging for a person to sustain. The goal should be to find an approach that supports nutrition and hydration while still honoring the person dealing with the diagnosis and setting them up for success.

Medications can help manage symptoms

Nutrition and hydration are the foundation of SBS care, but medications may also play an important role.

Antidiarrheal or antimotility medications can slow the movement of food through the intestine, which may help manage the diarrhea that frequently accompanies SBS.

Acid-reducing medications may also be used to decrease stomach acid that can contribute to damage of the intestinal lining and affect absorption.

And there is another important medication to know about: teduglutide, a GLP-2 analog.

Teduglutide is currently the only FDA-approved medication specifically for SBS. Unlike medications that primarily address symptoms, it is considered a disease-modifying treatment. It works by promoting structural and functional changes in the intestine, slowing intestinal transit, and improving nutrients and fluid absorption.

“Teduglutide has changed the paradigm of treatment of SBS because it is disease modifying; it structurally changes the bowel,” says Dr. Subramanian. “It doesn’t just slow transit; it enhances the capacity of the intestine to absorb. Patients have to be able to eat though in order for this treatment to be effective.”

Living with SBS can feel isolating

One of the most difficult parts of any invisible illness is explaining something that other people can’t see. People living with SBS and their caregivers and family members can benefit from connecting with others who understand the realities of the condition. SBS is not as dismal of a prognosis as it used to be. Support groups, advocacy organizations, and educational resources can help patients feel less alone and better equipped to advocate for their care.

If you or someone you love is living with short bowel syndrome, education and support can make a meaningful difference. The Med-IQ Short Bowel Syndrome Patient and Caregiver Education Resource Hub offers educational materials, links to patient advocacy and caregiver resources, and a clinical directory to help people find SBS care.

At 14, Crohn’s Made Her Question Motherhood. At 22, She’s Studying Why.

For women living with Crohn’s disease or ulcerative colitis, the question of whether to have children can carry a weight that goes far beyond the usual conversations about fertility and family planning.

Will my disease be controlled enough to have a healthy pregnancy? What happens if I flare while I’m pregnant? Will my medication affect my baby? What if I’m too sick to care for a child? What if breastfeeding means making another difficult medication decision? And the question that can be hardest to articulate: Will I be able to experience motherhood without IBD taking over the entire experience?

For Grace Hubbel, those questions aren’t simply academic. They are personal.

Diagnosed with Crohn’s disease at 14, Grace is now 22 and studying sociomedical sciences at the State University of New York at Geneseo. Her own experience with IBD and the stories she has heard from other women, led her to pursue an IRB-approved research study examining “The Impact of IBD on Decisions in Maternity and Emotional Wellbeing in Women.”

This week on Lights, Camera, Crohn’s a look at how her personal experience as a young woman with IBD inspired this incredible research and how you can get involved as a citizen scientist. Grace’s goal through her study, “The Impact of IBD on Decisions in Maternity and Emotional Wellbeing in Women” is to explore an area of IBD research that she believes has been overlooked: not simply what happens to a woman’s body during pregnancy, but what it feels like to make decisions about motherhood while living with an unpredictable chronic illness.

A Crohn’s diagnosis at 14

Grace grew up watching her older brother struggle with Crohn’s disease. He was diagnosed when he was starting college and nearly lost his life before his first surgery. When Grace began experiencing symptoms of her own at 14, she wasn’t completely surprised.

Her disease quickly became severe. She lost weight rapidly, her menstrual cycle stopped, and painful sores and ulcers made it difficult to swallow. She remembers feeling exhausted and unlike herself.

“I crawled into my mother’s bed once and told her it felt like I was disappearing with how I was losing pounds by the week,” Grace recalls.

At an age when many teenagers are focused on school, friends and figuring out who they are, Grace was learning a different vocabulary: tests, treatments, infusions, injections, and surgery.

“I was so young, I felt so different from my peers around me,” she says. “I spoke fluent in healthcare, in tests, I was forced to grow up so fast.”

Her Crohn’s journey has included steroids, infusions, injections, tests, a feeding tube, and surgery. At 22, Grace says she is still chasing total mucosal remission and continues to deal with hidden inflammation.

“Will I be able to become a mom someday?”

And almost immediately after her diagnosis, another question entered Grace’s mind.

Would she ever be able to become a mom?

Grace says motherhood was on her mind within months of being diagnosed.

Part of that fear came from watching someone she knew with Crohn’s experience a life-threatening postpartum flare and be unable to have more children. That story stayed with her and illustrates one of the most difficult aspects of IBD whether you’re a parent or not: uncertainty.

“The monstrous part about IBD is its uncertainty,” Grace says. “It never ceases to amaze me how for some individuals a round of medicine will get their body into remission, and another person will have unrelenting inflammation for years and years.”

For women with IBD, that uncertainty can intersect with some of life’s biggest decisions.

Grace knows this firsthand. Throughout various stages of her disease, she has wondered what a flare would look like during pregnancy or while caring for a young child.

What if severe diarrhea caused her to lose weight and made it difficult to get enough nutrients for a baby? What if medication affected her child’s immune system? What about breastfeeding and medication exposure?

Today, Grace takes Stelara, and she says she thinks about the fact that it can pass through breast milk. She has always dreamed of breastfeeding a baby but wonders how she would weigh that desire against the medical considerations.

And increasingly, another concern has emerged: the emotional experience of pregnancy itself.

“I worry most of all about having to work extra hard as a high-risk pregnancy and that I’d be obsessive about it all,” she says, “living outside of the special moments and experiences because of viewing it all through a clinical lens.”

That sentence captures something that statistics and clinical guidelines can’t always convey.

A pregnancy with IBD isn’t just a series of medical decisions. It can also be an emotional balancing act between wanting to enjoy a deeply meaningful life experience and being unable to completely turn off the part of your brain that is constantly monitoring your disease.

Seeing a gap in IBD research

As Grace learned more about IBD, she found comfort in understanding the disease from both scientific and sociological perspectives. She connected with other patients online and found women with IBD who had navigated motherhood and became role models for her.

That interest eventually led her to major in sociomedical sciences.

When it came time to develop an independent research project, she knew immediately that she wanted to study IBD and women’s health.

That project eventually grew into her current IRB-approved study. Grace noticed that while there is substantial scientific literature examining Crohn’s disease and ulcerative colitis during pregnancy and childbirth, there is far less research examining the qualitative experience of women living through motherhood with IBD.

In other words, researchers have studied many of the physical and medical questions. Grace wants to better understand the why behind women’s decisions, experiences, and emotions.

“This told me something was missing,” she says.

And the missing piece matters.

IBD is commonly diagnosed during reproductive years, meaning many women are forced to make decisions about fertility, pregnancy, breastfeeding, and family size while simultaneously navigating an unpredictable disease.

Could uncertainty itself be affecting women emotionally?

One of the findings that initially caught Grace’s attention was that women with IBD commonly report higher rates of psychological distress than men with IBD.

There are several explanations, but Grace wondered whether another factor deserved more attention.

Could the uncertainty surrounding fertility and motherhood contribute to that emotional burden?

“Could any of it have to do with how uncertain it can be for women to navigate a motherhood journey with an unpredictable illness such as IBD?” she asks.

That question became central to her research.

Rather than focusing solely on conception and pregnancy, Grace wants to understand the entire motherhood journey:

  • What does it mean to parent while living with IBD?
  • How do mothers explain their disease to their children?
  • Does becoming a parent change the way women cope with their illness?
  • How do women make decisions about breastfeeding or having additional children?
  • And perhaps most importantly, how do those decisions make women feel?

“These are the questions I want to explore,” Grace says.

Motherhood doesn’t end at delivery

One of the most compelling aspects of Grace’s research is her focus on what happens after pregnancy.

So much of the conversation around IBD and reproductive health centers on conception and pregnancy. But motherhood is a lifelong experience and IBD doesn’t disappear once a baby is born.

Grace says some of the women she has heard from have described waiting for their doctors to give them the “go-ahead” before trying to conceive.

Others have described delaying or avoiding medical care when they were very sick because they didn’t want to leave their children or frighten them.

But the stories aren’t exclusively difficult.

Grace says she has also heard about positive experiences, including mothers who have noticed their children developing deep empathy toward other people because they grew up with a mother living with IBD.

That is an important reminder: IBD can shape motherhood in challenging ways, but it can also shape families into beautiful ones. As an IBD mom of three kids (ages 9, 7, and 5) I can’t attest to this. Motherhood was the best decision I ever made and my kids are my constant motivation to push through, stay on top of managing my Crohn’s so I’m well for not only myself, but for them, and reminding me all my body is capable of despite my disease.

The decisions women make behind the scenes

One theme Grace has found particularly interesting is the way IBD can influence the timing of family planning. Some women wait for disease stability or medical approval before trying to conceive. Others make decisions about seeking medical care based on the needs of their children. These aren’t necessarily decisions that show up in a medical chart.

They’re the quiet calculations happening in the background of everyday life. And that’s exactly what Grace hopes her research will capture.

The study is designed to explore the experiences and emotional impacts behind these decisions, not simply whether a woman became pregnant or whether she experienced a flare. Because as we know, two women can have similar diagnoses and vastly different emotional experiences.

What Grace wants doctors to talk about earlier

Grace believes the conversation about fertility and family-building should begin much earlier in a woman’s IBD journey. She would like gastroenterologists to routinely ask young women at diagnosis whether they envision having children someday.

“I think it’s so important to get the conversation started and have it routine to discuss it,” she says.

Starting the conversation early can open the door to resources, questions, and appropriate reproductive counseling long before a woman is ready to have a baby. Grace also believes healthcare providers need to be honest about uncertainty.

“We need to be comfortable acknowledging what we don’t know,” she says, particularly when it comes to questions about the long-term effects of medications on children.

She also wants to see stronger communication between gastroenterologists and OB-GYNs.

She has heard women describe being confused about which physician to rely on during pregnancy and postpartum or receiving contradictory recommendations from their doctors.

“Greater communication between OB-GYN physicians, maternal fetal medicine doctors, and gastroenterologists on the topic of IBD and pregnancy is called for,” Grace says.

For patients, that kind of collaboration can mean the difference between feeling like they’re navigating pregnancy alone and feeling like they have a team.

Grace hopes her research changes the conversation

Grace hopes her research will expand how the IBD community thinks about women’s health. The physical side of IBD is important. But emotional wellbeing matters, too.

She points to the connection between psychological health and IBD outcomes, noting that emotional distress can influence disease activity. Her research suggests that the emotional stress of navigating motherhood alongside IBD may be one contributor to the psychological burden reported by women with the disease.

Her long-term goal is to highlight the need for more reproductive counseling and pregnancy programs specifically designed for women with IBD. Because women shouldn’t have to piece together this information on their own. And they shouldn’t have to wait until they’re ready to conceive to start asking questions.

“You will survive some of your biggest fears”

The most powerful part of Grace’s story isn’t the researcher speaking about the gaps in the literature. It’s the 14-year-old girl underneath it all.

If Grace could sit down with herself on the day she was diagnosed, she wouldn’t promise that IBD would become easy. Instead, she would tell her younger self that the disease would shape who she became and that some of that impact would become a source of purpose.

Her experiences would fuel her interest in healthcare and disability advocacy. She would meet healthcare workers who saw through her knowledgeable exterior and recognized the anxiety underneath. She would survive some of the things she feared most. And she would eventually find a partner who would make motherhood feel possible. But she’d also tell herself something many young people with chronic illness need to hear:

You don’t have to control everything.

“I’d tell her to enjoy being a young woman and let go of trying to control so much,” Grace says.

That’s easier said than done when your body has taught you from an early age that anything can change without warning. But that’s also why her message to other young women with IBD is so meaningful.

To the young woman with IBD dreaming about motherhood

Grace doesn’t know exactly what the future holds for her. She still has questions. She still has fears. She still lives with an unpredictable disease. But she isn’t letting uncertainty erase the possibility of motherhood. Her message to other young women with IBD is simple:

“Advocate for yourself and ask questions.”

She encourages women to establish an OB-GYN early and start talking about what pregnancy could look like in the future, even if motherhood is years away. And she wants women to know that they don’t have to abandon the dream simply because IBD may make the path more complicated.

“The reality is, it might be a little more sad and scary to manage,” Grace says. “But from what I’ve learned so far: no women have regretted the choice to pursue their dream, even if it looks different from what they expected.”

For a 22-year-old researcher who has spent much of her life learning to live with Crohn’s disease, Grace is asking a question that deserves far more attention:

What happens when we stop looking at motherhood with IBD solely through a medical lens and start listening to the women living it?

Her research is an important step toward answering it.
