Experiencing stomach pain right before you need to have a bowel movement is a surprisingly common issue. Many people find themselves wondering, “Why does my stomach hurt when I have to poop?” While it might seem counterintuitive, this discomfort can be a key indicator of underlying conditions related to how your gut and brain communicate. Michigan Medicine’s Disorders of Gut-Brain Interaction Clinic specializes in diagnosing and treating these conditions, offering comprehensive care for those experiencing these often-puzzling symptoms.
What are Disorders of Gut-Brain Interaction (DGBIs)?
Disorders of Gut-Brain Interaction, or DGBIs, are conditions that arise from miscommunication between your digestive system and your brain. This intricate network, often referred to as the gut-brain axis, is crucial for regulating digestion, sensation, and overall gut function. When this communication is disrupted, it can lead to a variety of symptoms throughout the gastrointestinal (GI) tract, from the mouth to the rectum, even though the organs themselves might appear structurally normal.

Two of the most common types of DGBIs are Irritable Bowel Syndrome (IBS) and Functional Dyspepsia (FD). Understanding these conditions is crucial to addressing the question of why your stomach might hurt when you need to poop.
Irritable Bowel Syndrome (IBS) Explained
Irritable Bowel Syndrome (IBS) is a condition characterized by a group of symptoms that significantly impact the large intestine. A hallmark symptom of IBS is lower stomach pain that can actually lessen after a bowel movement. Alongside this pain, individuals with IBS often experience bloating, constipation, and/or diarrhea. It’s estimated that a significant portion of the American population, around 20%, lives with IBS.
Diagnosing IBS isn’t as straightforward as an X-ray or blood test. Instead, it relies heavily on the symptoms a person reports to their doctor, after other potential causes have been ruled out. The link between stomach pain and bowel movements is a key factor in identifying IBS.
Functional Dyspepsia (FD) Described
Functional Dyspepsia (FD), sometimes referred to as “nonulcer dyspepsia” or “nervous stomach,” is another common DGBI. FD primarily affects the upper digestive system, and symptoms can include pain above the belly button, bloating, and nausea, often without vomiting. A persistent feeling of fullness can make it difficult for those with FD to eat normal-sized meals, and pain or bloating can linger for hours after eating. Importantly, unlike IBS, the pain associated with FD typically does not improve after a bowel movement.
Why Does Your Stomach Hurt Specifically When You Have To Poop?
The sensation of stomach pain intensifying when you feel the urge to poop, particularly if it’s relieved after a bowel movement, is strongly associated with Irritable Bowel Syndrome (IBS). Here’s why this happens:
-
Increased Sensitivity in the Gut: In individuals with IBS, the nerves in the gut can become hypersensitive. This means they react more strongly to normal processes like the movement of stool through the intestines or the stretching of the bowel walls. The anticipation of a bowel movement can trigger these sensitive nerves, leading to pain.
-
Muscle Spasms: The colon muscles contract to move stool towards the rectum for elimination. In IBS, these muscle contractions can be irregular or spastic, leading to pain and cramping. The urge to poop might coincide with these spasms, causing discomfort.
-
Gas and Bloating: Bloating is a common symptom of IBS. As gas accumulates in the intestines, it can cause pressure and pain. The need to defecate can sometimes exacerbate this pressure, leading to increased pain before relief is achieved through bowel movement.
-
The Gut-Brain Connection: The communication between the gut and brain plays a significant role in pain perception. Stress, anxiety, and even the anticipation of bowel movements can influence how the brain interprets signals from the gut, potentially amplifying pain sensations.
It’s important to remember that while pain before pooping can be a hallmark of IBS, it’s crucial to consult with a healthcare professional to rule out other potential causes and receive an accurate diagnosis.
Recognizing the Symptoms of DGBIs and IBS
Beyond the specific pain associated with the urge to poop, DGBIs and IBS present with a range of symptoms, including:
- Nausea
- Bloating
- Cramping below the belly button
- General stomach pain
- Constipation
- Diarrhea
These symptoms can vary in intensity and frequency, significantly impacting daily life for some individuals. DGBIs are surprisingly prevalent, affecting more than a third of the U.S. population.
Getting a Comprehensive Diagnosis for Gut-Brain Disorders
If you are experiencing persistent stomach pain related to bowel movements or other digestive symptoms, seeking a comprehensive diagnosis is essential. Clinics like the Disorders of Gut-Brain Interaction Clinic at Michigan Medicine employ a multidisciplinary approach to ensure accurate diagnosis and rule out other conditions, such as inflammatory bowel diseases like Crohn’s disease or ulcerative colitis.

Diagnosis often involves:
- Thorough Medical History and Physical Examination: Doctors will collect detailed information about your symptoms, medical history, and lifestyle.
- Rome III Criteria Assessment: These standardized criteria, developed by experts, help define DGBIs like IBS and FD based on symptom patterns. For IBS, this includes the criteria that pain is related to bowel movements or changes in stool frequency or appearance.
- Diagnostic Tests: To exclude other conditions, doctors may order various tests, including:
- Colonoscopy and flexible sigmoidoscopy: To examine the colon and rectum for abnormalities.
- Upper endoscopy: To visualize the esophagus, stomach, and upper small intestine.
- Esophageal and anorectal manometry: To assess muscle function in the esophagus and rectum.
- Laboratory tests: Blood and stool samples to check for infections or bleeding.
- Imaging tests: X-rays, CT scans, or MRIs to visualize the digestive system.
Treatment Options for IBS and Functional Dyspepsia
While there is no cure for DGBIs like IBS and FD, effective treatments are available to manage symptoms and improve quality of life. Treatment plans are often individualized and may include:
- Diet and Lifestyle Modifications: For many, changes to diet and lifestyle, such as stress reduction and exercise, can significantly alleviate symptoms. Registered dietitians can create personalized dietary plans.
- Medications: Over-the-counter or prescription medications can help manage specific symptoms like pain, diarrhea, or constipation.
- Physical Therapy and Biofeedback: These therapies can help retrain pelvic floor and anal sphincter muscles, improving bowel function.
- Clinical Trials: For some individuals, participation in clinical trials may offer access to cutting-edge treatments and contribute to advancing DGBI research.
Michigan Medicine’s multidisciplinary team, including GI physicians, dietitians, physical therapists, and behavioral therapists, works collaboratively to develop personalized treatment plans that address the unique needs of each patient.
