Why My Stomach Aches Softly and I Urgently Need the Restroom When Tense — There's a High Possibility of 'Irritable Bowel Syndrome'
Have you experienced stomach aches and urgency to use the restroom the night before a presentation, the morning of an important interview, or before going to an unfamiliar place? If you receive an endoscopy with no particularly abnormal findings but symptoms still repeat, Irritable Bowel Syndrome (IBS) should be prioritized for examination.
According to KDCA National Health Information Portal, irritable bowel syndrome is a chronic functional disorder "caused by the complex interaction of abnormal intestinal motility, visceral hypersensitivity, psychological factors, and changes in intestinal bacteria." Approximately 7-15% of the general population is reported to experience related symptoms. The key characteristic is repeated abdominal pain, diarrhea, constipation, and urgency of bowel movements without inflammation or structural abnormalities.
MSD Manual Korean Edition explains that according to the Rome Criteria, IBS is classified when abdominal pain repeats at least once per week for three months or more with association to bowel movements.
However, if bloody stools, unintended weight loss, or nocturnal abdominal pain disturbing sleep appear together, tests to first exclude organic disease should be performed. Carefully examining the pattern of symptoms and accompanying signs is the first step.
Why Does the Intestine React When Tense — The Gut-Brain Axis's Excessive Signals
Many people wonder "why specifically the intestine," but the brain and intestine are connected as a single communication system through the autonomic nervous system in real time. When the brain activates a stress response in a tense or anxious state, that signal can travel down the vagus nerve and sympathetic nervous system pathways to the intestine, making intestinal movement excessively fast or conversely slow.
Mayo Clinic explicitly states that "failed signal regulation between the brain and intestine can trigger pain, diarrhea, or constipation." PubMed Central's latest research (2023) summarizes that chronic stress and anxiety can upregulate cortisol secretion, disrupting intestinal microbiota balance and increasing visceral sensitivity through this mechanism. KDCA National Health Information Portal also explains that stress and psychological factors act as major mechanisms triggering or worsening IBS symptoms.
What this mechanism means is clear: dietary management alone may have limitations in producing fundamental change, and more systematic management becomes possible when approaches considering autonomic nervous system balance and psychological factors are pursued together.
Summary of Gut-Brain Axis Signal Flow
• Tension/anxiety → Brain secretes stress hormones (cortisol) • Via autonomic nervous system (sympathetic/vagal nerves) → Excessive signal transmission to intestine • Abnormal intestinal motility (acceleration or delay) → Abdominal pain, diarrhea, constipation, urgency of bowel movement • Upon chronification → Intestinal microbiota imbalance, increased visceral hypersensitivity
Gangbuk Anjeong Korean Medicine Clinic's Approach — Reading the 'Root Cause' of Sensitized Intestines by Constitution
Even when the same irritable bowel syndrome appears, it does not manifest the same way in everyone. Some experience explosive diarrhea whenever tense, others have cold and heavy abdomens, and still others have weak digestive capacity itself, feeling uncomfortable after eating just a little. Korean medicine distinguishes these differences through pattern differentiation (辨證) to change the direction of treatment.
According to NIKOM Korean Medicine Standard Clinical Practice Guidelines, combined treatment of acupuncture, moxibustion, and herbal medicine is recommended for irritable colon syndrome, with herbal formulas such as Yuk-gun-ja-tang, Soyou-san, and Tongsa-yobang utilized for symptom relief. Treatment prescription composition differs according to types such as liver qi constraint type (tension/nervousness-focused), spleen-kidney yang deficiency type (abdominal cold/diarrhea-focused), and spleen-stomach deficiency type (digestive capacity decline-focused).
Gangbuk Anjeong Korean Medicine Clinic bases constitutional diagnosis on 8-constitution medicine to distinguish whether the cause of tension-related intestinal response is autonomic nervous system imbalance or digestive capacity decline by constitution, then adjusts prescriptions on a weekly basis. Instead of uniform prescriptions in 2-4 week units, checking progress each week and reflecting it in prescriptions allows for detailed responses according to symptom changes. If there are accompanying symptoms such as abdominal stagnation, reflux esophagitis, or chronic indigestion, these are also examined together, with the goal of restoring the rhythm of the entire intestine.
Korean Medicine Approach Stages
• Constitutional diagnosis → Pattern differentiation classification based on 8-constitution medicine • Prescription design → Herbal composition matching the differentiated pattern type (utilizing Yuk-gun-ja-tang, Soyou-san, Tongsa-yobang, etc.) • Weekly progress check → Weekly prescription adjustment according to symptom changes • Lifestyle guidance → Constitution-specific customized dietary habits and autonomic nervous system stabilization living guidelines • Accompanying symptom management → Examining abdominal stagnation, reflux esophagitis, indigestion, etc. together
The Signal Your Stomach Sends — Do I Need Testing Right Now?
A considerable number of people whose stomachs react every time they feel tense fall within the IBS category. However, some symptoms may not be simply functional problems but rather signals requiring differentiation of organic diseases such as colorectal cancer or inflammatory bowel disease. Please carefully check the items below.
Warning Signals That Require Immediate Internal Medicine/Gastroenterology Testing
• Bloody or black stools appear • There has been recent unintended weight loss • You have woken from sleep due to abdominal pain during sleep • Your bowel habits suddenly changed after age 50 • There is a family history of colorectal cancer or inflammatory bowel disease • Anemia symptoms (dizziness, paleness) appear together
Wikipedia Irritable Bowel Syndrome specifies the above items as warning symptoms according to Rome Criteria IV differential diagnosis standards, and clinical literature recommends priority testing for organic disease exclusion such as colonoscopy for IBS-like symptoms that suddenly began after age 40. While irritable bowel syndrome itself does not directly progress to colorectal cancer or inflammatory bowel disease, differentiation is absolutely necessary because symptoms are similar.
If chronic and recurrent abdominal pain and bowel irregularities appear without the above warning signals, you can consider combined Korean medicine treatment after excluding organic disease through organ testing.

If Your Daily Life Is Narrowing Because of Your Stomach, Now Is the Time to Reconsider Your Body's Rhythm
An intestine that reacts every time you feel tense is not due to a 'sensitive personality.' It is more accurate to understand it as your body's signal that the balance of the brain-gut nervous system is being shaken. If going out feels reluctant, meal gatherings feel burdensome, and your stomach feels tense before important schedules, that narrowing of daily life itself becomes the starting point for treatment.
Gangbuk Anjeong Korean Medicine Clinic carefully examines the cause of tension-related abdominal pain you have endured long for on two axes — constitution and autonomic nervous system — so that the intestine can regain its own stability. The longer symptoms persist, the more the vicious cycle of anxiety and intestinal hypersensitivity tends to be reinforced. Identifying the cause type early and approaching systematically is advantageous for daily life recovery.
Located near Exit 3 of Suyu Station, with elevators fully equipped, and free use of large parking lots in the nearby Garden Tower (Dobong-ro 328), visiting by car is also convenient. Consultations begin at 8 AM every weekday, weekend, and holiday, and you can visit without waiting through Naver reservations.

We will work together to gradually widen your daily life that has shrunk because of your stomach.
Most Frequently Asked Questions at the Clinic from Those Whose Stomachs React Whenever They Feel Tense
Q1. I heard that irritable bowel syndrome shows normal results even with endoscopy testing, why is that?
Irritable bowel syndrome is a state where intestinal function itself becomes sensitized without inflammation or structural abnormalities. The fact that endoscopy and blood tests detect no abnormalities is actually a characteristic of IBS. Rather than neglecting symptoms because test results are normal, it is important to continue appropriate management as a functional disorder.
Q2. My stomach only hurts when tense or on presentation days, is this really a disease or am I just sensitive?
It is not a matter of personality. The brain and intestine are connected by the autonomic nervous system, so psychological tension can actually trigger abnormal intestinal motility. This is called the gut-brain axis (Gut-Brain Axis) mechanism and is a medically recognized pathogenesis of functional disease. Self-blame should be replaced with understanding and managing the cause.
Q3. Whether I have diarrhea or constipation changes daily, how should I manage this?
Alternating diarrhea and constipation is commonly observed in mixed-type IBS (IBS-M). The more inconsistent bowel patterns are, the more likely they are affected by complex influences of diet, stress, and sleep. Recording the pattern itself — diarrhea one day, constipation another — helps identify the cause during consultations.
Q4. I go to the restroom immediately when I consume caffeine or spicy food, do I just need to be careful with food?
Dietary management is an important management tool but may not be sufficient alone. It is true that caffeine and irritating foods irritate the intestine, but if symptoms are more severe during stress despite eating the same food, the autonomic nervous system and constitutional digestive capacity must also be examined together. If daily life recovery is difficult with food restriction alone, a root cause approach is necessary.
Q5. Can irritable bowel syndrome improve with Korean medicine treatment? Can I take it together with Western medicine?
Korean medicine standard clinical practice guidelines recommend acupuncture and herbal medicine treatment for irritable colon syndrome, with customized approaches possible according to constitution and pattern differentiation. If you are currently taking Western medicine, please inform this during consultation. After confirming whether there are drug interactions, the decision to combine treatments should be made together for safety.
