Epigastric Pain Syndrome (EPS): Read in the order of your curiosity
Before using the term 'functional' lightly
Analyzing whether epigastric pain occurs during fasting, after meals, or at night
Epigastric Pain Syndrome(EPS) is a pattern of functional dyspepsia centered on pain or burning in the epigastric region. It does not only occur after meals and may overlap with postprandial distress syndrome. If you experience black stools, vomiting blood, weight loss, difficulty swallowing, persistent vomiting, or if pain suddenly worsens, you must undergo a causal evaluation first rather than dismissing it as a functional symptom.
Symptom patterns and next steps
Distinguishing between postprandial distress, epigastric pain, and symptoms that should not be ignored
The amount eaten, relationship to meals, location, and functional impairment, rather than the name of the symptom, determine the next evaluation.
| Current scenario | Clues for interpretation | Next action |
|---|---|---|
| Feeling full for a long time after eating a small amount and difficulty finishing a meal | PDS pattern centered on postprandial fullness or early satiety | Medical evaluation after recording the amount eaten and recovery time |
| Pain or burning sensation in the epigastric area (upper center of the abdomen) that varies in relation to meals | EPS pattern, may overlap with PDS | Record the location, intensity, and timing relative to meals |
| Centered on burning sensation behind the sternum or acid reflux | Accompanied by GERD or a separate condition | Evaluate by distinguishing the reflux scenarios |
| Pain in the upper right abdomen, jaundice, or persistent severe abdominal pain | Possible other causes such as biliary tract or pancreas | Prompt gastrointestinal evaluation |
| Hematemesis, melena, difficulty swallowing, weight loss, or chest pain spreading to the jaw or arms | Possible bleeding, obstruction, or cardiac emergency | Immediate emergency or gastroenterological evaluation |
When to seek medical attention first
Symptoms that should not be dismissed as functional dyspepsia
The following symptoms require a priority evaluation for acute bleeding, obstruction, biliary/pancreatic, or cardiac causes.
- Hematemesis, coffee-ground vomiting, or black and sticky stools
- Difficulty or pain when swallowing, or frequent or persistent vomiting
- Unintentional weight loss, loss of appetite, or jaundice
- New and persistent severe pain in the epigastrium or upper abdomen
- Chest pain spreading to the jaw, neck, or arms, or accompanied by shortness of breath
Epigastric pain that persists after tests
When burning sensations cannot be explained by stomach acid alone
If epigastric pain recurs even after suppressing stomach acid, we set the goals for Korean herbal medicine treatment by distinguishing between stomach sensation/motility and stomach heat, cold sensations, tension, and chronic dryness or poor recovery.
Distinguishing between heat sensations and cold-induced pain
The direction of prescription differs between stomach heat, characterized by burning and thirst, and Spleen-Stomach Deficiency-Cold, where the digestive system contracts after consuming cold foods.
Examining the relationship between tension and the timing of pain
Distinguishing Liver-Stomach Disharmony, where the epigastric region feels tight after presentations, meetings, or insomnia.
Aiming for pain-free meals and sleep
The goal is not just to lower a pain score, but to reach a point where you do not avoid meals and do not wake up during the night.
Treatment GoalsWe aim to increase the number of meals and nights without epigastric pain, and to ensure that if pain does occur, it lasts for a shorter duration.
Consultation for Epigastric Pain Syndrome (EPS) using meal and bowel movement records
For early satiety and epigastric discomfort, we examine the amount eaten, the start time, and how long it lasted after the meal together.
The illustrations showing the processes occurring in the body are simplified explanations to help understand the location and changes of symptoms; they do not represent an individual's test results or treatment outcomes.If you have had these experiences
For those who experience burning and pain in the epigastric region both while fasting and after meals
If epigastric pain recurs even after acid suppression, we set the goals for Korean herbal medicine treatment by categorizing gastric sensation and motility along with gastric heat, cold sensations, tension, chronic dryness, and decreased recovery.
For those who experience recurring epigastric pain despite endoscopy showing no major abnormalities that explain the symptoms
When epigastric pain and burning sensations persist for a long time even after tests
For those who still experience burning and pressure even after taking acid suppressants
acid suppressants When the response is insufficient or symptoms return quickly after discontinuing medication
For those who wish to examine the relationship between pain and tension, sleep, and cold foods
When you want to simultaneously manage pain along with heat/cold sensations, tension, and sleep
In functional dyspepsia, even without mucosal damage, differences in how the upper stomach adapts to and senses food after a meal can lead to early satiety and epigastric pressure.

Epigastric Pain Syndrome (EPS): Why we look at both test results and mealtime discomfort
Epigastric Pain Syndrome (EPS) is Functional Dyspepsia a condition centered on pain or burning sensations in the epigastric region. It does not only occur after meals and may overlap with postprandial distress syndrome. If you experience black stools, vomiting blood, weight loss, difficulty swallowing, persistent vomiting, or if pain suddenly worsens, you must undergo a causal evaluation first rather than dismissing it as a functional symptom.
We first rule out risks of bleeding, obstruction, biliary/pancreatic, or cardiac issues
Black stools,vomitingswallowing difficulties, weight loss, jaundice, the location of pain, and chest symptoms are checked to prioritize necessary gastrointestinal or emergency evaluations.
Distinguishing between the post-meal discomfort type and the solar plexus pain type
early satiationWe analyze the amount of food consumed, the recovery time after meals, and the relationship between meals and solar plexus pain or burning sensations.
Checking how much easier eating, dining out, and working have become
Rather than looking only at pain scores, we track the actual recovery of meal portions, the interval between meals, and the ability to dine out or go to work.
Reasons why it may not heal well
Epigastric Pain Syndrome (EPS): Why meals may remain uncomfortable even after tests
If epigastric pain recurs even after acid suppression, we set the goals for Korean herbal medicine treatment by categorizing gastric sensation and motility along with gastric heat, cold sensations, tension, chronic dryness, and decreased recovery.
Distinguishing between heat sensations and cold-induced pain
The prescription direction differs between gastric heat, characterized by burning and thirst, and Spleen-Stomach Deficiency-Cold, where the stomach shrinks after consuming cold foods.
Examining the temporal relationship between tension and pain
We distinguish Liver-Stomach Disharmony, where the epigastric region feels tight after presentations, meetings, or insomnia.
Aiming for meals and sleep without pain
The goal is not simply to lower a pain score, but to reach a point where you do not avoid meals and do not wake up during the night.
How to keep a symptom timetable
Epigastric Pain Syndrome (EPS): Meal schedules are more important than the names of foods
Please prepare photos or notes pointing to the painful area, the start time (whether fasting, after meals, or at night), duration, changes in acid reflux, vomiting, or bowel movements, endoscopy and Helicobacter results, and a list of current medications.
Pain in the center of the epigastrium
Observe whether the pain can be pointed to with a finger or if it is a broad feeling of fullness and pressure.
Burning sensation
Distinguish whether it is reflux rising toward the chest or a heat sensation remaining in the epigastrium.
Fasting and post-meal
Note when the symptoms start, whether on an empty stomach, at night, or immediately after a meal, and how long they last.
Along with gastritis symptoms, mucosal changes, potential causative medications, and the presence of infection are confirmed through necessary tests.

Why EPS prescriptions differ based on cold sensations, stagnation, heat, or tension
Prescription priorities vary depending on whether the epigastric pain is burning, cold and contracting, or tightening after tension.
When there is burning, dry mouth, and soreness
Observe if the heat sensation in the epigastrium, acid reflux, and soreness increase after meals or at night. Check for overlapping symptoms such as thirst, dry mouth, or heat in the upper body.constipationThe focus is on clearing the stomach and descending rebellious qi to lower the heat in the stomach and the energy surging upward.
When there is a dull pain while cold or on an empty stomach
Observe if the pain eases with warmth or eating a little, and worsens after cold foods. Ask if there are cold hands and feet, loose stools, or decreased energy. The focus is on warming the center and strengthening the spleen and stomach functions.
When the epigastrium tightens and burping is blocked after tension
Observe if pain and chest tightness increase immediately after stress and if they change after sighing.burping Check if insomnia, palpitations, or a foreign body sensation in the throat occur together. The focus is on soothing the liver and harmonizing the stomach to resolve qi stagnation and restore stomach motility.
Changes to monitor during treatment
Recovery to observe in the next meal
The goal is to increase the number of meals and nights without epigastric pain and to ensure that if pain occurs, it lasts for a shorter duration.
Pain location and intensity (0-10)
By recording the 'pain location and intensity (0-10)' along with the time before and after meals, we observe if the amount of food intake and the time it takes to feel comfortable actually change.
Start time during fasting, post-meal, or at night
By recording the 'start time during fasting, after meals, or at night' along with the times before and after meals, we observe whether the amount of food consumed and the time it takes to feel comfortable actually differ.
Before and after taking medication, tension, sleep, or consuming cold foods
By recording 'before and after taking medication, tension, sleep, or consuming cold foods' along with the times before and after meals, we observe whether the amount of food consumed and the time it takes to feel comfortable actually differ.
Even if tests show no significant structural abnormalities, the regulation of the autonomic and enteric nervous systems, sensory sensitivity, and motility rhythms can vary depending on meals, sleep, and stress.
Conceptual reference · NIDDK: Disorders of Gut-Brain InteractionAt the crossroads of gastrointestinal motility, sensation, and the gut-brain response
Epigastric Pain Syndrome is categorized into stomach heat, spleen and stomach deficiency-cold, and liver-stomach disharmony
The priority of the prescription varies depending on whether the epigastric pain is burning, cold and contracting, or tightening after tension.
Pattern identification is not about arbitrarily adding a disease name to test results. A single person may experience a combination of decreased gastric motility, hypersensitivity, body heat, cold sensations, and tension; if the primary symptoms change based on diet, bowel movements, or sleep, the proportions of the prescription are adjusted accordingly.
When there is a burning sensation, dry mouth, and soreness
- Changes to observe in digestive symptoms
- We observe whether the heat sensation in the epigastric area, acid reflux, and soreness increase after meals or at night.
- Changes to observe in the rest of the body
- We check for overlapping symptoms such as thirst, dry mouth, heat in the upper body, and constipation.
- Prescription priority
- The focus is on clearing stomach heat and descending reflux to lower the heat in the stomach and the energy surging upward.
When there is a dull pain when cold or on an empty stomach
- Changes to observe in digestive symptoms
- We observe whether the pain decreases with warmth or eating a small amount, and whether it worsens after consuming cold foods.
- Changes to observe in the rest of the body
- We ask if there is coldness in the hands and feet, loose stools, or decreased energy.
- Prescription priority
- The focus is on warming the center and strengthening the spleen to warm the interior and reinforce gastrointestinal function.
When the epigastric area tightens and burping is blocked after tension
- Changes to observe in digestive symptoms
- We observe whether pain and discomfort increase immediately after stress and whether they change after sighing or burping.
- Changes to observe in the rest of the body
- We check if insomnia, palpitations, and a foreign body sensation in the throat occur together.
- Prescription priority
- The focus is on soothing the liver and harmonizing the stomach to resolve qi stagnation and restore stomach motility.
When you feel exhausted even after eating a small amount and recovery is slow until the next meal
- Changes to observe in digestive symptoms
- We observe not only the intensity of Epigastric Pain Syndrome (EPS) but also the amount of food that can be eaten and the recovery time after meals.
- Changes to observe in the rest of the body
- We check if post-meal drowsiness, loss of energy, loose stools, and coldness in the hands and feet occur on the same day.
- Prescription priority
- We increase the proportion of treatment to strengthen the spleen and stomach's ability to receive and transport nutrients.
Order of prescription adjustment
- Distinguish between heat, cold, and tightening of the pain
Even for the same burning sensation, the sensation and the triggering scenario are determined first.
- Evaluate the cause and the response to medication
Endoscopy results, test findings, and reactions to medications are prioritized over pattern identification (Byun-jeung).
- Adjustments are made based on the recovery of eating and sleeping patterns
We check if the number of days you can eat and sleep without pain is increasing.
Why consider Korean herbal medicine treatment now?
- When pain or burning sensations in the epigastric area persist long after tests
- When the response to acid suppressants is insufficient or symptoms return quickly after discontinuation
- When you wish to simultaneously manage pain, temperature sensitivity (cold/heat), tension, and sleep
What is evaluated in herbal medicine treatment for this condition
- Location of pain and intensity on a scale of 0–10
- Start time: while fasting, after meals, or at night
- Medications taken and timing relative to tension, sleep, or consuming cold foods
Seek medical evaluation first for bleeding, jaundice, or chest pain
If you experience vomiting blood, black stools, repeated vomiting, jaundice, chest pain, or difficulty breathing, the necessary medical evaluation takes priority over scheduled Korean herbal medicine treatment.
List pain experienced while fasting, after meals, and during the night separately
Check whether the pain stays in the epigastric area or is a burning sensation that rises behind the chest, and whether it starts before or after eating and how long it lasts.
Compare meals and sleep that were pain-free
Rather than just looking at whether pain intensity increases, we look at meals eaten comfortably, nights where you did not wake up due to pain, and the time it took to feel comfortable after pain started.
Things to prepare before the consultationPlease prepare photos or notes pointing to the painful area, the start time (fasting, after meals, or at night), duration, changes in acid reflux, vomiting, or bowel movements, endoscopy and Helicobacter results, and a list of current medications.
If bleeding, anemia, worsening difficulty swallowing, persistent vomiting, unexplained weight loss, or nighttime diarrhea newly occur, they must be re-evaluated even if past tests were normal. After ruling out these cases, we focus on herbal medicine treatment for chronic or recurring functional digestive symptoms.

Frequently Asked Questions about Epigastric Pain Syndrome (EPS)
Where does Epigastric Pain Syndrome hurt?
It primarily centers on pain or burning sensations in the epigastric area. Please let us know the specific location you can point to with your finger and whether it is worse while fasting, after meals, or at night.
Does the epigastric area only hurt when eating?
It can occur regardless of meals or may worsen after eating. We check whether the pain started before eating, the time the first pain occurred, and how long it lasted.
What is the difference between a burning sensation in the epigastrium and reflux-related heartburn?
Pain or burning that stays in the epigastrium (the upper central abdomen) and heartburn or acid reflux that rises behind the chest may differ in location and response to posture. If both sensations overlap, please record the starting time for each separately.
Are there cases where I need an immediate examination when experiencing epigastric pain?
If you experience vomiting blood, black stools, persistent vomiting, difficulty swallowing, unexplained weight loss, jaundice, chest pain, or shortness of breath, the necessary medical evaluation takes priority over scheduled Korean herbal medicine treatment.
If early satiety is also present, is it a different disease?
If early satiety and postprandial fullness occur together, PDSthey may overlap. Rather than choosing a single diagnosis, we look at whether the pain or the feeling of fullness interferes more with your meals and daily life.
If Helicobacter is present, is the cause of the epigastric pain confirmed?
If infection is confirmed, eradication therapy is prioritized, and the response to treatment is monitored. If epigastric pain persists after treatment, we re-evaluate the current symptoms and other causes, such as ulcers.
What changes should I look for during Korean herbal medicine treatment?
It is not just about the intensity of the pain. We compare the number of meals you can eat without pain, the number of nights you sleep without waking up, and the time it takes to feel comfortable once pain occurs.
