Non-Erosive Reflux Disease (NERD): Read in order of your curiosity
Before using the term 'functional' lightly
Reflux discomfort can persist even if visible damage is minimal
Non-Erosive Reflux Disease (NERD) is a condition where typical reflux symptoms are present, but no esophageal erosion is visible on an endoscopy. The fact that an endoscopy is normal does not mean the symptoms are fake, but not all burning sensations are caused by reflux. If the response to medication is insufficient, we verify the dosage and diagnosis, and if necessary, perform pH or impedance tests to distinguish from other causes such as esophageal hypersensitivityfunctional heartburn and other causes.
Symptom Classification
Why we look at time, posture, and symptoms that should not be ignored rather than just a single sensation
Even for the same chest or throat discomfort, the priorities for evaluation differ.
| Observed Scenario | Points to Consider | Next action |
|---|---|---|
| Heartburn and acid reflux after meals | Typical reflux type | Medical evaluation after recording diet, posture, and frequency |
| Waking up from sleep due to acid reflux or coughing after lying down | Nighttime reflux/sleep disturbance type | Record the time of the last meal and bedtime |
| Persistent foreign body sensation in the throat, hoarseness, or cough only | Atypical symptoms and other causes | Evaluation including laryngeal and respiratory causes |
| Food getting stuck or pain when swallowing | Esophageal complications or other diseases | Prompt gastrointestinal evaluation |
| New oppressive chest pain, shortness of breath, or cold sweats | Possible cardiac emergency | Immediate emergency evaluation |
When to seek medical attention first
Symptoms that should not be mistaken for reflux
We first check for the possibility of cardiac emergencies, esophageal obstruction, or bleeding.
- If there is new oppressive or squeezing chest pain accompanied by shortness of breath, cold sweats, or radiating pain
- If food or water gets stuck, swallowing becomes difficult, or pain during swallowing progresses
- If you are vomiting blood or coffee-ground-like material, or have black, sticky stools
- If you experience persistent vomiting, loss of appetite, and unexplained weight loss
Reflux discomfort that persists even when no visible wounds are present
If esophageal sensation and gastric reflux persist even after reducing stomach acid
If symptoms recur after evaluating the cause and verifying the medication method, we set herbal medicine treatment goals by distinguishing between gastric reflux, esophageal hypersensitivity, tension-related tightening, and coldness or weakness of the spleen and stomach.
Distinguishing between heartburn and throat/chest discomfort
We observe whether acid reflux, burning sensations, a foreign body sensation in the throat, and chest pressure occur at the same time.
Distinguishing between heat-type reflux and Qi stagnation of phlegm
The prescription focus differs between a sensation of heat surging upward and a sensation of the throat and chest feeling blocked when tense.
Observing daily life after the response to medication
We verify whether there are actual changes in the time spent sleeping lying down, post-meal activities, and discomfort during meetings.
Treatment GoalsThe goal is to reduce heartburn and reflux discomfort after meals and at night, and to increase the time you can comfortably lie down, speak, and work.
Consultation via diet and bowel movement records for Non-Erosive Reflux Disease (NERD)
Even if no erosion is seen on an endoscopy, reflux events and esophageal hypersensitivity can lead to heartburn, chest tightness, and throat discomfort.
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 still experience heartburn and chest tightness despite a normal endoscopy
If symptoms recur after evaluating the cause and verifying the medication method, we set herbal medicine treatment goals by distinguishing between gastric reflux, esophageal hypersensitivity, tension-related tightening, and coldness or weakness of the spleen and stomach.
For those whose throat and chest discomfort remain even though some symptoms decreased after taking acid suppressants
When reflux symptoms recur for a long time despite no erosion on endoscopy
For those whose heartburn varies after meals, when lying down, or during tension
acid suppressants When a feeling of a lump in the throat or chest tightness persists
For those confused between non-erosive reflux, functional heartburn, and laryngopharyngeal reflux
When you want to manage reflux discomfort alongside diet, posture, and tension
The evaluation of heartburn and acid reflux varies depending on the timing after meals, lying posture, and whether swallowing discomfort is present.

Non-Erosive Reflux Disease (NERD): Why test results and dietary discomfort are viewed together
Non-Erosive Reflux Disease(NERD) is a pattern where typical reflux symptoms exist, but no esophageal erosion is seen on endoscopy. The fact that an endoscopy is normal does not mean the symptoms are fake, but it also does not mean all heartburn is caused by reflux. If the response to medication is insufficient, the dosage and diagnosis are reviewed, and if necessary, pH and impedance tests are used to distinguish esophageal hypersensitivity from other causes.
First, we rule out cardiac chest pain, bleeding, and swallowing risks
We check the pattern of chest pain, shortness of breath, cold sweats, food getting stuck, vomiting blood, black stools, and weight changes.
Categorizing into postprandial, nocturnal, and atypical types
heartburn· We examine acid reflux and the timing of lying down, nighttime awakening, and other causes of a lump in the throat, hoarseness, or coughing.
Please record the timing of medication and the functional response during day and night
By tracking the timing and response to antacids or PPIs, as well as the impact of sleep, meetings, and dining out, we determine the goals for re-evaluation and Korean herbal medicine treatment.
Reasons why it may not heal well
Non-Erosive Reflux Disease (NERD): Why meals may remain uncomfortable even after testing
If symptoms recur after evaluating the cause and reviewing the medication method, we set Korean herbal medicine treatment goals by distinguishing between upward stomach reflux, esophageal hypersensitivity, tension-related constriction, and coldness or weakness of the spleen and stomach.
Distinguishing between burning sensations and throat or chest discomfort
We observe whether acid reflux, burning sensations, a feeling of something stuck in the throat, and chest pressure occur at the same time.
Distinguishing between febrile upward surge and phlegm-qi stagnation
The treatment approach differs for symptoms that feel like heat surging upward versus those where the throat and chest feel blocked during tension.
Evaluating daily life after the response to medication
We verify whether there are actual changes in the time spent sleeping lying down, post-meal activities, and discomfort during meetings.
How to keep a symptom timetable
Non-Erosive Reflux Disease (NERD): Meal schedules are more important than specific food names
Please prepare information regarding the dates of heartburn and acid reflux, the intervals between meals and bedtime, nighttime awakening or coughing, food getting stuck, bleeding, weight changes, and the timing and response to antacids or PPIs.
Whether reflux events align with symptoms
We check if acid reflux and burning sensations occur after eating or lying down, and whether these align with the timing of acidity tests.
Esophageal hypersensitivity
There may be patterns where pain is felt intensely even with minor reflux.
Functional heartburn and other causes
functional heartburnIf the correlation with reflux is low or the pattern of chest pain is different, we re-evaluate including cardiac or musculoskeletal causes.
Since hoarseness and a feeling of something stuck in the throat can have various causes other than reflux, we also check the duration, voice usage, and changes in swallowing.
Conceptual reference · AAO-HNS: Laryngopharyngeal RefluxKorean herbal medicine pattern identification for Non-Erosive Reflux Disease (NERD)
Why prescriptions for Non-Erosive Reflux Disease (NERD) differ based on cold sensations, stagnation, heat, and tension
Even when there are no visible lesions, the symptoms differ depending on whether there is a hot surging sensation, a feeling of blockage in the throat, or a cold sensation with slow digestion.
When acid and burning sensations surge upward
We look for hot heartburn, acid reflux, and bad breath after meals or at night. We check for accompanying symptoms such as thirst and heat in the upper body.constipationThe focus is on clearing stomach heat and descending the upward-surging energy.
When the throat and chest feel blocked due to tension
We observe whether the foreign body sensation in the throat or chest tightness fluctuates regardless of swallowing. We ask if these symptoms occur alongside sighing, palpitations, or insomnia. The focus is on regulating qi and resolving phlegm to relieve the blockage in the throat and chest.
When there is a cold sensation, bloating, and reflux persists for a long time
We observe whether digestion is slow and watery acid refluxburpingpersists for a long time after meals. We check for sensations of cold, loose stools, or fatigue. The focus is on warming the spleen and stomach and descending the energy.
Changes to monitor during treatment
Recovery to observe in the next meal
The goal is to reduce heartburn and reflux discomfort after meals and at night, and to increase the time you can lie down, speak, and work comfortably.
Medications, time of intake, and remaining symptoms
By recording 'medications, time of intake, and remaining symptoms' along with the time before and after meals, we observe whether the amount of food intake and the time it takes to feel comfortable actually change.
Onset and duration after meals or lying down
By recording 'onset and duration after meals or lying down' along with the time before and after meals, we observe whether the amount of food intake and the time it takes to feel comfortable actually change.
Throat/chest tightness and changes in tension or sleep
By recording 'throat/chest tightness and changes in tension or sleep' along with the time before and after meals, we observe whether the amount of food intake and the time it takes to feel comfortable actually change.
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
Non-erosive reflux is categorized into stomach heat surging, phlegm-qi stagnation, and spleen-stomach deficiency-cold
Even when there are no visible lesions, the symptoms differ depending on whether there is a hot surging sensation, a feeling of blockage in the throat, or a cold sensation with slow digestion.
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 acid and burning sensations surge upward
- Changes to observe in digestive symptoms
- We look for hot heartburn, acid reflux, and bad breath after meals or at night.
- Changes to observe in the rest of the body
- We check for accompanying symptoms such as thirst, heat in the upper body, and constipation.
- Prescription priority
- Focus on clearing stomach heat and descending rebellious energy to lower stomach heat and bring down rising energy.
When tension causes a feeling of blockage in the throat and chest
- Changes to observe in digestive symptoms
- Check if the foreign body sensation in the throat or chest tightness fluctuates regardless of swallowing.
- Changes to observe in the rest of the body
- Ask if symptoms occur together with sighing, palpitations, or insomnia.
- Prescription priority
- Focus on regulating Qi and resolving phlegm to resolve phlegm and Qi stagnation and relieve blockage in the throat and chest.
When there is a cold sensation, bloating, and prolonged reflux
- Changes to observe in digestive symptoms
- Check if digestion is slow and if watery acid reflux or burping persists long after meals.
- Changes to observe in the rest of the body
- Check for cold sensitivity, loose stools, or fatigue.
- Prescription priority
- Focus on warming the center and descending rebellious energy to warm the spleen and stomach and direct energy downward.
When you feel exhausted even after eating a small amount and recovery is slow until the next meal
- Changes to observe in digestive symptoms
- Evaluate not only the severity of Non-Erosive Reflux Disease (NERD) but also the amount of food that can be consumed 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
- Separate heartburn, acid reflux, and foreign body sensation in the throat
Do not group these into a single reflux score.
- Apply pattern identification based on test results and response to medication
Do not skip necessary evaluations simply because the condition is non-erosive.
- Adjust based on post-meal and nighttime lifestyle
Observe if the patient can lie down more comfortably and if the time they can spend talking increases.
Why consider Korean herbal medicine treatment now?
- When reflux symptoms recur for a long time despite no erosion found on endoscopy
- When a foreign body sensation in the throat or chest tightness remains even after taking acid suppressants
- When you wish to manage diet, posture, and tension along with reflux discomfort
What is evaluated in herbal medicine treatment for this condition
- Current medications, timing of intake, and remaining symptoms
- Onset and duration after eating or lying down
- Tightness in the throat and chest, and changes in tension or sleep
First, we screen for cardiac chest pain, bleeding, and swallowing risks
We check the pattern of chest pain, shortness of breath, cold sweats, food getting stuck, vomiting blood, black stools, and weight changes.
Categorized into postprandial, nocturnal, and atypical types
We examine heartburn, acid reflux, the timing of lying down, nighttime awakenings, and other causes of foreign body sensation in the throat, hoarseness, or coughing.
Please record the timing of medication intake and functional responses during the day and night
We track the timing and response to antacids or PPIs, as well as the impact of sleep, meetings, and dining out, to re-evaluate and set goals for Korean herbal medicine treatment.
Things to prepare before the consultationPlease prepare the dates of heartburn and acid reflux, the intervals between meals and bedtime, nighttime awakenings or coughing, food getting stuck, bleeding, weight changes, and the timing and response to antacids or PPIs.
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 Non-Erosive Reflux Disease (NERD)
Can it be reflux if I only have a cough or hoarseness without heartburn?
It is possible, but cannot be confirmed based on those symptoms alone. We evaluate other potential causes such as rhinitis, asthma, laryngeal diseases, and smoking, along with symptoms occurring after meals or at night.
When should I go to the emergency room for chest pain?
If you experience new oppressive pain, pain radiating to the arms, jaw, or back, shortness of breath, cold sweats, or nausea, seek immediate emergency cardiac evaluation.
Should I seek medical evaluation immediately if food gets stuck?
If food getting stuck is recurrent or progressing, ordysphagiaif there is pain during swallowing (odynophagia), do not wait and assume it is simple reflux; seek prompt gastrointestinal evaluation.
What should I record if acid regurgitation only occurs at night?
Please record the time of your last meal, the time you lay down, the time and frequency of waking up, coughing, next-day fatigue, and the timing and effect of any medication taken.
Is this a disease caused by excessive stomach acid production?
We do not explain this solely by excess stomach acid. We examine the reflux defense barrier that prevents stomach contents from rising into the esophagus, along with structural factors, abdominal pressure, and exposure factors.
Do I have to quit coffee and spicy foods for the rest of my life?
No. Rather than applying a blanket ban for everyone, we identify only the specific items that repeatedly worsen your condition through meal and symptom logs.
If I think it was caused by medication I am taking, can I stop taking it?
Do not stop medication on your own. Please inform your medical staff of the names and start dates of any prescription drugs, over-the-counter medicines, or supplements so they can review the necessity, alternatives, and dosage.
