Is it Enteritis or IBS? How to Distinguish and Treat Intestinal Issues

When sudden abdominal pain and diarrhea start, many worry, "Is it enteritis?" Even after seeing a doctor, many feel frustrated hearing, "There's no specific abnormality, but it seems like Irritable Bowel Syndrome (IBS)." Although the symptoms are similar, the causes and treatments for enteritis and IBS are completely different. Today, we will clearly distinguish between these two common intestinal problems and look at the fundamental solutions offered by Dalimchae Clinic.

💡 [Key Answer] The 3 most common reasons for recurring abdominal pain and diarrhea: ① Enteritis is acute inflammation of the intestinal mucosa caused by viral or bacterial infection. ② IBS is a chronic functional abnormality of the intestine (gut-brain axis imbalance) with no signs of inflammation. ③ The two can be distinguished by the duration of symptoms and the presence of inflammation in tests. Dalimchae Clinic fundamentally resolves intestinal problems through gut detox and autonomic nervous system stabilization.

IBS and enteritis both have abdominal pain and diarrhea as primary symptoms, but they differ in cause, symptom patterns, and duration. Enteritis is an acute inflammatory disease mainly caused by viral or bacterial infections. Symptoms such as sudden pain, diarrhea, vomiting, and fever appear within hours or days of consuming contaminated food, and generally improve within a short period (days to 2 weeks).

On the other hand, IBS is a functional bowel disorder characterized by chronic abdominal pain, bloating, and changes in bowel habits like diarrhea or constipation, despite no inflammation or structural abnormalities in the gut. Often, no specific abnormalities are found in endoscopies or blood tests. If symptoms repeat for more than 3 months, IBS may be suspected. Symptoms tend to worsen with stress, certain foods, or fatigue, and are closely linked to autonomic nervous system imbalance or Gut-Brain Axis dysfunction.

If you suffer from ongoing pain, diarrhea, or constipation despite hearing "everything looks normal," it is highly likely to be IBS. IBS is not a structural problem of the intestine itself, but often stems from an imbalance in the 'Gut-Brain Axis,' the intestinal function control system. Our brain and gut are closely connected; when the brain is stressed, it affects gut function.

For example, when the brain feels excessive stress or anxiety, it can cause disturbances in the autonomic nervous system that regulates gut movement, leading to abnormal reactions where the gut moves too fast or too slow. This increases intestinal wall permeability, allowing toxins to enter easily, or causes gut microbial imbalance, leading to chronic abdominal discomfort. At Dalimchae Clinic, we focus on identifying these complex causes for fundamental improvement.

Yes, chronic intestinal problems can be significantly improved through fundamental gut detox treatment. Gut health is directly linked to overall health beyond simple digestion. When toxins accumulated in the intestinal wall enter the blood and spread throughout the body, they can lead to various systemic symptoms such as decreased immunity, chronic inflammation, skin issues, and chronic fatigue. In IBS patients, gut microbial imbalance and intestinal mucosal dysfunction are commonly observed.

Dalimchae Clinic's gut detox goes beyond just emptying the gut; it aims to help the intestinal mucosa recover and create a beneficial gut microbial environment to strengthen the gut's inherent detox function. This prevents toxin accumulation, reduces inflammatory responses, relieves pain and diarrhea, and helps regain gut health. Specifically, herbal treatments have been shown to be effective in improving gut microbial balance and regulating inflammation.

According to a study reported in Herald Economy in 2026, a research team demonstrated that Gwakjeong-tang-gami significantly improved symptoms in patients with diarrhea-predominant IBS. In a randomized clinical trial of 60 adults, the group taking Gwakjeong-tang-gami had a treatment response rate more than twice as high as the placebo group. The overall symptom improvement rate reached 55.2%, significantly higher than the 26.7% in the placebo group, proving a statistically significant effect. Researchers explained that this shows the herbal medicine can directly regulate intestinal inflammatory responses, the core cause of IBS.

Based on this data, Dalimchae Clinic provides customized herbal prescriptions to improve the gut environment and enhance the intestinal wall's recovery power to prevent recurrence.

Additionally, a multi-center study published in the Journal of Radiation Research in 2020 confirmed that TJ-14 (Banhasasim-tang) was effective in 86% of patients with acute radiation-induced enteritis, significantly reducing daily bowel movements (P=0.02).

As such, herbal medicine has scientific evidence for regulating inflammatory responses and helping repair damaged intestinal mucosa. At Dalimchae Clinic, we aim for fundamental recovery, not just symptom suppression.

Our gut detox treatment aims to build a body that can maintain its own health by regaining the balance of intestinal functions.

Toxins on the intestinal wall create systemic inflammation through the blood. These toxins arise from weakened intestinal wall function due to microbial imbalance, poor eating habits, and stress. A weakened barrier allows harmful substances to easily penetrate the blood, causing systemic inflammation, which can manifest as chronic intestinal diseases like IBS, as well as atopy, reflux esophagitis, headaches, and dizziness.

At Dalimchae Clinic, we prescribe customized gut detox herbal medicine after a thorough diagnosis of each patient's constitution and gut status. This medicine inhibits harmful bacteria, promotes the growth of beneficial ones, and regenerates damaged mucosa to strengthen barrier function. It also improves gut motility and promotes digestive enzyme secretion.

Gut detox restores gut health to increase overall immunity and helps the brain and gut communicate smoothly by regaining autonomic balance. This reduces the gut's sensitivity to stress and plays a key role in preventing recurrence. Through this, you can regain not just gut health but overall physical vitality and quality of life.

IBS Self-Diagnosis Checklist

If 3 or more items apply, IBS may be suspected. If 5 or more, consult with Dalimchae Clinic.

• Repeated abdominal pain for 3 or more days a month over the last 3 months.
• Pain tends to be relieved after a bowel movement.
• Accompanied by changes in frequency (diarrhea or constipation).
• Changes in stool form (watery, hard, etc.).
• Frequent gas, bloating, and abdominal fullness.
• Feeling the urge to go immediately after eating.
• Stomach pain and diarrhea when stressed or nervous.
• Frequent feeling of incomplete evacuation (residual stool).
• Uncomfortable stomach and frequent bathroom visits upon waking.
• Immediate intestinal trouble after eating specific foods.

[Criteria & Action]

• 3 or more: 'Suspected' stage → Review lifestyle and consider herbal complex treatment.
• 5 or more: 'Strongly suspected' stage → Recommended for immediate precision diagnosis and customized treatment.

Q. How long does IBS last? A. IBS is a chronic condition where symptoms can cycle through improvement and worsening. Proper treatment and management can control symptoms and prevent recurrence.

Q. Can enteritis become chronic? A. Most acute enteritis improves within 2 weeks, but it can become chronic if immunity is weak. Chronic enteritis can show similar symptoms to IBS, making accurate diagnosis and treatment important.

Q. Can IBS and reflux esophagitis be treated together? A. Yes. Both are often linked to Gut-Brain Axis imbalance and autonomic nervous system issues. We treat the common causes of both simultaneously.

Q. Does stress really affect gut problems that much? A. Yes. Stress directly affects the Gut-Brain Axis, disrupting gut motility and increasing permeability. We reduce the impact of stress through autonomic stabilization treatment.

IBS or chronic enteritis are not problems solved by enduring. You no longer have to ignore your body's signals. If approached correctly, the body responds faster than you think. Bring your symptoms as they are. At Dalimchae Clinic, we will find the cause together.
