Reflux Esophagitis: Causes, Grading, and Treatment

Reflux esophagitis is inflammation and erosion of the esophageal lining caused by stomach acid, pepsin, and sometimes bile flowing backward into the esophagus. It’s the erosive form of GERD (gastroesophageal reflux disease), and it’s diagnosed on endoscopy, graded by severity, and treated with a staged approach that starts with acid suppression and lifestyle changes.

Here’s what to do right now, depending on what you’re experiencing:

• Start lifestyle measures and consider an OTC or prescription PPI trial if you have typical heartburn and regurgitation without alarm features.
• Schedule a GI appointment within one to two weeks if symptoms persist despite two to four weeks of acid suppression, or if you’ve been on daily antacids for months without a real diagnosis.
• Seek urgent or emergency care today if you have progressive difficulty swallowing, vomiting blood or passing black stools, unintentional weight loss, severe pain swallowing, or a sensation that food is stuck and won’t pass.

That last category isn’t optional. Food impaction, active GI bleeding, and progressive dysphagia are signs the esophagus may already have a stricture, an ulcer, or something that needs same-day evaluation, not a wait-and-see approach.

Key Takeaways

Reflux esophagitis is a treatable, well-understood condition where the right PPI timing and grading-based follow-up drive most successful outcomes.

What Is Reflux Esophagitis, and How Does It Differ From GERD?

Reflux esophagitis is what happens when GERD actually damages the tissue. GERD is the broader disease process, chronic symptoms or mucosal injury caused by stomach contents flowing back into the esophagus, and the American College of Gastroenterology defines it as exactly that: a spectrum of chronic symptoms or visible tissue damage from abnormal reflux. Reflux esophagitis is the subset of GERD where an endoscope actually shows erosions in the esophageal lining.

That distinction matters clinically because not everyone with reflux symptoms has visible damage. Gastroenterologists split GERD into two camps:

Erosive reflux disease means an endoscopy shows breaks in the esophageal mucosa, actual erosions or ulcerations you can see and photograph during the procedure. This is reflux esophagitis in the strict sense.

Nonerosive reflux disease (NERD) means the patient has classic reflux symptoms, heartburn, regurgitation, sometimes chest discomfort, but the endoscopy looks normal or nearly normal. No visible erosions, even though acid exposure testing often confirms abnormal reflux is happening.

This split matters for how you’re managed. Erosive disease has an objective marker doctors can track through healing; NERD is treated based on symptom response since there’s no lesion to reexamine. Reflux disease overall is common: Western prevalence estimates run roughly 10% to 20% of the population, with severe erosive disease affecting around 6%. If your reflux showed up on endoscopy, you’re not an outlier. You’re in a well-studied, well-treated group of patients.

What Causes Reflux Esophagitis, and Who’s Most at Risk?

The root cause is a lower esophageal sphincter (LES) that isn’t doing its job. The LES is a ring of muscle at the junction between your esophagus and stomach that’s supposed to stay closed except when you swallow. In reflux esophagitis, that sphincter either relaxes too often at the wrong times (called transient LES relaxations) or has chronically low resting pressure, letting acidic stomach contents splash upward repeatedly.

Several conditions make that sphincter failure more likely, or make the damage worse once reflux occurs:

• Hiatal hernia, where part of the stomach pushes up through the diaphragm, physically disrupting the LES’s anti-reflux barrier.
• Obesity (BMI over 30), which increases intra-abdominal pressure and pushes stomach contents upward.
• Age over 50, when LES tone and esophageal clearance both tend to decline.
• Smoking and alcohol use, both of which relax the LES directly.
• Delayed gastric emptying, which leaves more volume in the stomach available to reflux.
• Pregnancy, from a combination of hormonal relaxation and mechanical pressure.

The ACG identifies these same risk factors, hiatal hernia, age over 50, elevated BMI, smoking, and alcohol, as the core drivers behind who develops erosive disease versus who doesn’t.

Medications deserve their own mention because they’re an underappreciated cause. Nitrates, calcium channel blockers, and anticholinergic drugs all relax the LES as a side effect. Separately, certain oral medications, doxycycline, potassium chloride, bisphosphonates, and some NSAIDs among them, can cause direct chemical injury to the esophageal lining if they get lodged there. This is called pill-induced esophagitis, and it’s mechanically distinct from acid reflux even though it produces similar symptoms.

Pro Tip: Take pills with a full glass of water, at least four ounces, and stay upright for 30 minutes afterward. Lying down right after swallowing a capsule is one of the most common and most preventable causes of a painful, self-inflicted esophageal ulcer.

How Does Reflux Damage the Esophagus, and What Do the Los Angeles Grades Mean?

Acid alone doesn’t tell the whole story. Stomach acid, the enzyme pepsin, and in some patients bile salts that reflux up from the duodenum all combine to break down the protective barrier of the esophageal lining. Normally, saliva and esophageal contractions clear this material quickly. When clearance is impaired, whether from a weak LES, poor motility, or lying flat too soon after eating, that exposure time stretches out and the tissue starts to break down.

Under the microscope, early injury shows up as inflammatory infiltrates and basal cell hyperplasia. As damage progresses, you see actual erosions, then deeper ulcerations. In long-standing, severe cases, the squamous cells lining the esophagus can be replaced by a different, more acid-resistant columnar cell type, a change called intestinal metaplasia. That’s Barrett’s esophagus, and it’s a recognized precursor to esophageal adenocarcinoma, which is why grading and follow-up matter so much.

Endoscopists use the Los Angeles (LA) classification to describe exactly how much damage they see, and this system drives a lot of the treatment decision-making downstream.

For perspective on what these grades mean in practice: most patients across all grades achieve meaningful mucosal healing within 8 to 12 weeks on an appropriately dosed PPI. Grade A and B disease tends to respond reliably within the typical treatment window. Grade C and D disease may require dose escalation, a longer treatment duration, or follow-up endoscopy to confirm healing rather than just symptom improvement.

What Symptoms Point to Reflux Esophagitis, and Which Ones Are Emergencies?

Heartburn is the headline symptom, but it’s rarely the only one. Typical presentations include a burning sensation behind the breastbone, regurgitation of sour or bitter material into the throat or mouth, chest discomfort that can mimic cardiac pain, and a sensation of food sticking on the way down (dysphagia). Some patients also describe painful swallowing (odynophagia), a persistent lump-in-the-throat feeling (globus), or, when reflux reaches the throat and airway, chronic cough, hoarseness, or a sore throat that doesn’t respond to usual remedies. Mayo Clinic notes that painful or difficult swallowing, chest pain, heartburn, and food impaction are the core symptom cluster clinicians look for, regardless of the underlying cause.

Here’s the part that surprises a lot of patients: symptom severity and endoscopic severity don’t always match. Someone with mild, intermittent heartburn can turn out to have Grade C esophagitis on endoscopy, while another patient with daily, miserable symptoms can have a completely normal-looking esophagus. That mismatch is exactly why persistent or worrying symptoms justify a look with the scope rather than an assumption based on how bad it feels day to day.

A separate set of symptoms should never be managed with over-the-counter antacids or “wait and see.” These are the alarm features:

• Progressive difficulty swallowing, especially if solids are getting stuck when they didn’t before
• Inability to swallow liquids or your own saliva
• Vomiting blood, or stools that are black and tarry (signs of GI bleeding)
• Unintentional weight loss you can’t explain
• Severe or worsening pain with swallowing
• A sensation that a piece of food is truly stuck and not moving

Pro Tip: If you suspect food impaction, don’t try to force it down with more food, water, or a home remedy you found online. Go to an emergency department. A lodged food bolus can perforate the esophagus if pushed against, and it needs to come out under direct visualization, not guesswork.

How Is Reflux Esophagitis Diagnosed?

Most patients don’t start with a scope. The typical pathway begins with a clinical assessment: your doctor reviews your symptom pattern, risk factors, and medication list, and if nothing raises a red flag, an empiric trial of a proton pump inhibitor is often the first move. If symptoms improve substantially within two to four weeks, that response itself is considered diagnostically supportive of reflux disease.

Upper endoscopy (EGD) becomes necessary when any alarm feature is present, when symptoms don’t respond to an adequate PPI trial, when dysphagia is part of the picture, or when there’s a reason to specifically look for Barrett’s esophagus, such as long-standing symptoms in someone over 50. During an EGD, the gastroenterologist passes a thin, flexible scope with a camera through the mouth into the esophagus, stomach, and first part of the small intestine, directly visualizing and grading any erosions using the LA classification, and taking biopsies if metaplasia, infection, or eosinophilic disease is suspected.

Two additional tests come into play for more complicated cases. Ambulatory pH-impedance monitoring involves wearing a thin catheter or a temporarily placed capsule that records acid exposure and reflux episodes over 24 to 96 hours, and it’s the test of choice when symptoms persist despite PPI therapy or when the diagnosis is genuinely unclear. Esophageal manometry measures the pressure and coordination of esophageal muscle contractions and is used mainly to rule out motility disorders before considering anti-reflux surgery, or to evaluate unexplained dysphagia. According to the Merck Manual’s clinical overview, advanced reflux testing is generally most informative when performed off acid-suppressing therapy, since the goal is to capture reflux behavior as it naturally occurs.

Testing becomes mandatory, not optional, in a specific set of situations: any alarm feature listed above, new dysphagia at any age, suspected Barrett’s esophagus, and symptoms that don’t respond to a reasonable PPI trial.

How Do You Treat Reflux Esophagitis?

Treatment follows a staged approach, and the goal at every stage is the same: control acid exposure long enough for the esophageal lining to actually heal, not just feel better.

1. Start with lifestyle measures. Weight loss if BMI is elevated, elevating the head of the bed, avoiding meals within three hours of lying down, and cutting known trigger foods and alcohol — details on these lifestyle changes can be found in this free ebook on wellness and longevity.
2. Begin a PPI trial for 8 to 12 weeks. This is the backbone of treatment for both erosive and nonerosive disease, and it’s what most patients need to achieve mucosal healing on a first course, according to the ACG’s treatment recommendations.
3. Reassess at the end of the trial. If symptoms and, for erosive disease, endoscopic findings have resolved, many patients can step down to the lowest effective dose or on-demand therapy. If response is partial, the next step is usually dose escalation to twice daily.
4. Escalate for non-responders or high-grade disease. Persistent Grade C or D esophagitis, confirmed Barrett’s esophagus, or symptoms that don’t budge on maximized medical therapy are the signals to consider further intervention.

Here’s how the common medication classes stack up:

PPI timing trips up more patients than almost anything else in this treatment plan. These drugs are prodrugs that need to be activated by acid inside actively secreting proton pumps, which is why taking a PPI right before a meal, when the stomach is gearing up to produce acid, works far better than taking it with food or at bedtime on an empty stomach. A patient who takes their omeprazole with lunch and calls it “not working” is often dealing with a timing problem, not a drug-failure problem.

When medical therapy genuinely isn’t enough, gastroenterologists consider procedural options. Surgical fundoplication, wrapping the top of the stomach around the LES to reinforce it, remains the traditional surgical answer for patients with a large hiatal hernia, confirmed reflux on testing, and normal motility on manometry. Less invasive endoscopic anti-reflux procedures and transoral incisionless fundoplication (TIF) offer an option for select patients who want to avoid traditional surgery but haven’t achieved control with medication alone. Referral to a surgeon is generally reserved for confirmed anatomical problems, refractory symptoms despite optimized medical therapy, or complications like a large paraesophageal hernia.

Pro Tip: If a once-daily PPI isn’t cutting it, ask about splitting the dose, one before breakfast and one before dinner, rather than simply doubling the morning dose. Twice-daily dosing timed around meals often controls symptoms that once-daily higher doses miss.

What Diet and Lifestyle Changes Actually Help?

Diet is genuinely first-line therapy here, not a nice-to-have alongside medication. The foods most likely to provoke reflux share a common mechanism: they either relax the LES directly or irritate already-inflamed tissue.

Foods and habits to limit:

• Fatty and fried foods, which slow gastric emptying and relax the LES
• Chocolate, caffeine, and peppermint, all known LES relaxants
• Alcohol, especially in the evening
• Spicy and highly acidic foods (citrus, tomato-based sauces) if they trigger your symptoms specifically
• Large meals eaten within three hours of bedtime

Foods and habits that tend to help:

• High-fiber whole grains like oatmeal and brown rice
• Lean proteins prepared without heavy frying or added fat
• Non-citrus fruits such as bananas, melon, and apples
• Smaller, more frequent meals instead of two or three large ones
• Staying upright for 2 to 3 hours after eating

Harvard Health’s clinical guidance backs this same pattern, and Cleveland Clinic’s dietary recommendations add that avoiding late-night meals and favoring lower-fat preparations makes a measurable difference for most patients within a few weeks.

A reasonable sample day looks like this: oatmeal with banana for breakfast, a grilled chicken salad with olive oil dressing at lunch, an apple or a handful of almonds as a mid-afternoon snack, and a modest portion of baked fish with brown rice and steamed vegetables for dinner, finished at least three hours before bed.

Pro Tip: Keep a simple food diary for two weeks, logging what you ate, when, and any symptoms that followed within a few hours. Generic trigger-food lists are a starting point, but bringing your own pattern to a GI visit lets your doctor personalize recommendations instead of guessing. Precision Digestive Health’s guide to lifestyle changes that actually work walks through how to structure that log.

What Complications Can Untreated Reflux Esophagitis Cause?

Left unmanaged, chronic reflux esophagitis doesn’t just stay uncomfortable, it can cause structural damage that’s harder to reverse. The NIDDK identifies esophageal stricture, ongoing esophagitis, and Barrett’s esophagus as the main long-term risks of untreated GERD, and chronic inflammation specifically raises the chance of ulceration and bleeding in the esophagus.

Esophageal strictures develop when repeated cycles of injury and healing lay down scar tissue that narrows the esophagus, causing progressive dysphagia, usually to solid foods first. Bleeding can occur from deep ulceration eroding into a blood vessel, sometimes presenting subtly as anemia rather than dramatic vomiting of blood. Barrett’s esophagus, the metaplastic change from squamous to columnar cells, occurs in a subset of chronic, severe cases and carries an elevated long-term risk of esophageal adenocarcinoma, which is why patients diagnosed with Barrett’s typically enter a surveillance endoscopy schedule rather than a one-time treatment plan. Reflux can also cause damage outside the esophagus itself: dental erosion from repeated acid exposure in the mouth, chronic cough, and laryngitis from reflux reaching the throat and vocal cords.

The encouraging counterpoint is that most patients heal well with proper treatment. Grade A and B esophagitis typically resolves within the standard 8 to 12 week PPI course. The patients who need long-term maintenance therapy are a specific subset: those with Grade C or D disease at diagnosis, confirmed Barrett’s esophagus, symptoms that recur quickly whenever medication stops, or a history of bleeding or stricture. If you fall into one of those categories, ongoing PPI therapy and periodic surveillance endoscopy aren’t overtreatment, they’re the standard of care.

What Else Could Cause Esophagitis Besides Reflux?

Not every case of esophagitis is reflux-driven, and telling them apart matters because the treatments diverge completely.

• Eosinophilic esophagitis (EoE) is an allergic/immune condition, more common in younger patients and those with a history of asthma, eczema, or food allergies. Biopsy shows a dense infiltrate of eosinophils, and endoscopy sometimes reveals characteristic rings or linear furrows rather than the erosions typical of acid damage.
• Pill-induced esophagitis causes a localized, often sharply demarcated injury, and the medication history (recent bisphosphonate, doxycycline, or NSAID use, especially taken without enough water) is usually the giveaway.
• Infectious esophagitis, caused by Candida, herpes simplex virus, or cytomegalovirus, shows up almost exclusively in patients who are immunosuppressed, whether from HIV, chemotherapy, or immunosuppressive medication, and biopsy or brush cytology confirms the specific organism.
• Radiation-related esophagitis occurs in patients who’ve had radiation therapy to the chest, with a clear timeline tying symptom onset to treatment.
• Autoimmune causes, less common, can involve conditions like scleroderma affecting esophageal motility and secondarily causing reflux-pattern injury.

Where this gets clinically tricky is distinguishing EoE from reflux-related eosinophilia, since acid reflux itself can cause some eosinophils to show up on biopsy. An empiric PPI trial sometimes serves double duty here: if eosinophilic changes resolve on repeat biopsy after PPI therapy, that supports a reflux-driven process rather than primary EoE. If eosinophils persist despite adequate acid suppression, that points toward true EoE and a different treatment path entirely, typically dietary elimination or topical steroids rather than escalating PPI doses.

What Should You Expect at a GI Visit or During an EGD?

Walking into a gastroenterology appointment prepared makes the visit far more productive. Bring a written symptom log (when symptoms occur, what triggers them, how long they last), your two-week food diary if you’ve started one, a full list of current medications including over-the-counter antacids, H2 blockers, or PPIs you’ve already tried, and any prior endoscopy reports or imaging if this isn’t your first evaluation.

If your doctor recommends an EGD, here’s the practical rundown. You’ll be asked to fast, typically nothing to eat or drink for 6 to 8 hours beforehand, and most patients receive sedation, ranging from light IV sedation to deeper anesthesia depending on the practice and patient preference. The procedure itself usually takes 10 to 20 minutes: a thin, flexible scope goes through the mouth, down the esophagus, into the stomach and the first part of the small intestine, letting the physician directly see and grade any erosions and take biopsies if needed. Recovery from sedation typically takes 30 to 60 minutes in a monitored setting, and most patients need a ride home and can resume normal eating the same day, often starting with lighter foods. You can find a fuller walkthrough of what these procedures involve, including risks and preparation specifics, in Precision Digestive Health’s guide to common endoscopy procedures.

Expect your gastroenterologist to ask pointed questions: when symptoms started, whether they’ve changed in character or frequency, what makes them better or worse, whether you’ve had any trouble swallowing, and whether you’ve noticed weight loss or bleeding. Precise answers here, ideally backed by your symptom log, often shorten the path to an accurate diagnosis and the right treatment plan on the first visit.

A Clinician’s Note on Living With Reflux Esophagitis

Reflux esophagitis is one of those conditions where the priority isn’t just calming symptoms, it’s catching complications early and personalizing treatment so patients aren’t stuck on a higher dose or a longer course than they actually need. Most people respond well to a properly timed PPI trial and reasonable lifestyle adjustments, and the esophagus is remarkably good at healing itself once acid exposure is controlled.

What gets overlooked is how much the details matter: taking a PPI at the right time relative to meals, distinguishing reflux from a mimicking condition like eosinophilic esophagitis before assuming treatment has failed, and not dismissing symptoms as “just heartburn” when dysphagia or weight loss are part of the picture. Minimizing long-term medication side effects while still controlling the disease is a real balancing act, and it’s one worth having an actual conversation about rather than staying on autopilot with an over-the-counter pill for years.

If you notice any alarm feature, bleeding, progressive difficulty swallowing, unexplained weight loss, don’t wait for your next scheduled checkup. That’s a same-week or same-day evaluation, not a “mention it at my annual visit” situation.

Getting an Accurate Diagnosis and a Treatment Plan That Fits

If you’ve been cycling through over-the-counter antacids for months without a clear answer, or your symptoms haven’t budged despite a reasonable PPI trial, the next step is an actual look at what’s happening in your esophagus rather than another guess. Precision Digestive Health, led by board-certified gastroenterologist Dr. Meet Parikh in South Plainfield, NJ, offers the full diagnostic and treatment pathway in one place: in-office evaluation, upper endoscopy (EGD) with Los Angeles grading and biopsy when indicated, coordination of ambulatory reflux testing for cases that need it, and ongoing PPI management with follow-up to confirm healing rather than just assuming it happened.

For patients whose disease is more advanced or who haven’t responded to standard therapy, Dr. Parikh also coordinates referral for endoscopic or surgical options when medical management alone isn’t enough. If your reflux symptoms have lasted more than a few weeks, or you’re managing a known erosive esophagitis diagnosis and want a personalized plan instead of a generic one, visit the gastroenterology services page to learn more or schedule a consultation.

FAQ

What foods are good for esophagitis?

High-fiber whole grains, lean proteins, and non-citrus fruits like bananas and melon tend to be well tolerated, while fatty, fried, spicy, and highly acidic foods, plus caffeine, chocolate, and alcohol, are common triggers worth limiting.

How do you fix reflux esophagitis?

Most cases heal with an 8 to 12 week course of a properly timed proton pump inhibitor combined with lifestyle changes like weight management, smaller meals, and staying upright after eating; more severe grades sometimes need dose escalation or a longer course.

Is reflux esophagitis serious?

It can be, especially if left untreated: chronic cases raise the risk of esophageal stricture, bleeding, and Barrett’s esophagus, which carries a long-term cancer risk, though most patients who get diagnosed and treated appropriately heal well.

What is the fastest way to cure esophagitis?

There’s no true shortcut, but taking your PPI 30 to 60 minutes before the first meal of the day, rather than with food, meaningfully improves how quickly the standard 8 to 12 week healing course works.
