If you have LPR (silent reflux), start with an ENT doctor, and if possible a laryngologist, who is an ENT specialising in the voice box and throat. LPR shows up in the throat, and an ENT is the specialist who can look at your larynx with a camera, rule out other throat problems and judge whether reflux is the likely cause.

A gastroenterologist becomes important if you also have heartburn or regurgitation, if food sticks lower down in your chest, if you have warning signs like weight loss, if you need an endoscopy or reflux monitoring, or if surgery is being considered. Many people with stubborn LPR end up needing both.

The frustrating part is the gap between them. ENTs often send LPR patients to GI, GI finds a normal esophagus and sends them back, and nobody owns the problem. Below I’ll explain why that happens and how to avoid getting stuck in the loop.

Key Takeaways

For throat symptoms such as hoarseness, throat clearing, a lump feeling, chronic cough or post-nasal drip, see an ENT first.
A laryngologist is the best match for LPR. In one international survey they used objective reflux testing more than twice as often as general ENTs.
See a gastroenterologist if you have heartburn, regurgitation, food sticking in your chest, trouble swallowing, weight loss or anemia, or if you need an endoscopy, pH-impedance testing or reflux surgery.
LPR patients get bounced because LPR often causes no heartburn and no esophageal damage, so a normal endoscopy doesn’t rule it out.
Throat scope findings alone are unreliable: most healthy volunteers show at least one “reflux sign”.
Bring your Reflux Symptom Index score, a symptom diary and a list of everything you’ve tried. It makes the appointment far more productive.
Start diet and lifestyle changes while you wait. They help LPR and don’t interfere with testing in most cases.

Why LPR Patients Get Bounced Between ENT and GI

I hear this story constantly from readers, and I lived a version of it myself. You go to an ENT with a hoarse voice and constant throat clearing. They scope your throat, see some redness, say “it’s reflux”, give you a PPI and refer you to gastroenterology. The gastroenterologist scopes your esophagus, finds it looks normal, asks if you get heartburn, you say no, and they conclude it isn’t reflux. Back to the ENT you go.

Each specialist is doing their job correctly. The problem is that LPR sits right on the border between the two specialties, and each one’s tests can miss it.

LPR often doesn’t look like GERD

Most people with LPR don’t have heartburn. In the original research that defined the condition, nearly all patients came in with throat and voice symptoms, and only a minority had heartburn at all [Koufman, The Laryngoscope, 1991]. The esophagus is much tougher than the throat, so it can handle reflux episodes that would irritate the larynx without showing visible damage. A normal endoscopy tells you your esophagus is healthy. It doesn’t tell you whether reflux is reaching your throat.

Throat scope findings are not specific

The opposite problem happens on the ENT side. The redness and swelling that suggest reflux on a throat scope are surprisingly common in people without any symptoms. In a study of 52 healthy, non-smoking volunteers with no throat or reflux history, 93% had at least one “reflux sign” when examined with a flexible scope through the nose [Milstein et al., The Laryngoscope, 2005]. So “your throat looks a bit red” isn’t proof of LPR either, which is partly why a gastroenterologist may be sceptical.

PPIs often don’t work well for LPR

Many people are told that if a PPI doesn’t fix their throat, it can’t be reflux. But PPIs reduce acid, not reflux itself, and pepsin and non-acid reflux can still irritate the throat. In a major randomized trial of people with chronic throat inflammation, high-dose esomeprazole for 16 weeks did no better than placebo [Vaezi et al., The Laryngoscope, 2006]. That doesn’t mean reflux wasn’t there; it means acid suppression alone wasn’t enough. I explain this in why PPIs don’t work for LPR.

Even ENTs differ

An international survey of 535 ENT surgeons found big differences between laryngologists (ENTs who specialise in the voice box) and general ENTs. General ENTs were much more likely to refer LPR patients to gastroenterology (45% vs 28%). Laryngologists were more than twice as likely to use impedance-pH testing (31% vs 14%) and twice as likely to know about non-acid reflux (35% vs 16%) [Lechien et al., The Laryngoscope, 2020]. In other words, the specialist most familiar with LPR is less likely to send you elsewhere and more likely to test you properly.

What an ENT Does for LPR

An ENT, or better a laryngologist, is the right first stop for throat-based reflux symptoms. A typical appointment includes:

A look at your throat and voice box with a thin flexible camera passed through the nose. It takes a few minutes and isn’t painful, though it feels odd.
Grading any reflux signs, often using the Reflux Finding Score, which scores swelling and redness in specific areas of the larynx [Belafsky et al., The Laryngoscope, 2001].
Ruling out other causes of your symptoms, such as vocal cord nodules or polyps, post-nasal drip, an enlarged lingual tonsil, muscle tension in the voice, or, rarely, something more serious. This reassurance is one of the most valuable parts of the visit.
Starting treatment, usually diet and lifestyle changes, an alginate and sometimes a medication trial.
Referring you to a voice or speech therapist if throat clearing, voice strain or chronic cough are part of the picture. See voice therapy for silent reflux.

Some laryngologists can also arrange objective reflux testing themselves, including 24-hour impedance-pH studies with a sensor positioned high in the throat. If your symptoms are clearly throat-based, ask whether they can do this before you’re referred elsewhere.

What a Gastroenterologist Does for Reflux

A gastroenterologist specialises in the esophagus, stomach and gut. For someone with LPR, they’re most useful for:

Upper endoscopy, to check for esophagitis, Barrett’s esophagus, a hiatal hernia, eosinophilic esophagitis or other problems. See endoscopy for acid reflux.
Reflux monitoring, such as 24-hour impedance-pH or a wireless Bravo pH test, which measures how much reflux you actually have. Gastroenterologists interpret these using the Lyon Consensus criteria [Gyawali et al., Gut, 2024].
Esophageal manometry, which checks how well your esophagus squeezes and how strong the valve at the bottom is. See esophageal manometry.
Medication management, including PPIs, H2 blockers, prokinetics and newer drugs.
Assessing you for procedures such as the LINX device, TIF or fundoplication. Nobody should have reflux surgery without proper testing first.

Interestingly, gastroenterology’s own guideline recognises the overlap. The American College of Gastroenterology suggests that people with throat or airway symptoms but no typical heartburn should have objective reflux testing rather than being put on long-term PPIs blindly, and that non-reflux causes should be looked for with specialists such as ENT [Katz et al., American Journal of Gastroenterology, 2022].

Which Specialist Should You See? A Symptom Guide

Start with an ENT (ideally a laryngologist) if your main symptoms are:

Hoarseness or a voice that tires easily
Frequent throat clearing or mucus you can’t shift
A lump or something-stuck feeling in the throat, which I cover in lump in throat from reflux
A chronic cough or tickle, especially after meals or lying down
Post-nasal drip that doesn’t respond to nasal treatment
A sore or burning throat with no heartburn
Choking or breath-catching episodes at night

Start with a gastroenterologist if your main symptoms are:

Heartburn or chest burning
Regurgitation of food or acid into your mouth
Food sticking in your chest, rather than the throat
Upper abdominal pain, bloating or nausea alongside reflux
Reflux symptoms for many years, especially if you’re over 50, which raises the question of Barrett’s esophagus

You’ll likely need both if:

You have throat symptoms and heartburn or regurgitation
Your throat symptoms haven’t improved after three months of diet changes and medication
You’re considering reflux surgery or a procedure
Your ENT and GI findings disagree and you need objective testing to settle it

ENT or gastroenterologist for GERD?

If you have classic GERD, meaning heartburn and regurgitation without much throat involvement, your GP or primary care doctor can usually manage it, and the specialist to see when it’s not settling is a gastroenterologist. An ENT only becomes relevant if throat or voice symptoms develop. For a broader picture of tests, see how acid reflux is diagnosed.

How to Avoid Getting Bounced Back and Forth

These are the steps I’d suggest to anyone with LPR heading into a specialist appointment. They make it much more likely you’ll leave with a plan instead of another referral.

Score yourself on the Reflux Symptom Index before you go and bring the result. It’s the questionnaire ENTs use, and a score above 13 suggests reflux is likely [Belafsky et al., Journal of Voice, 2002]. You can do it here: Reflux Symptom Index.
Keep a two-week symptom diary. Note when symptoms are worst, what you ate and drank, and how you slept. Patterns such as “worse after dinner” or “worst on waking” are very persuasive to a specialist.
List everything you’ve tried, including which medications, at what dose, for how long, and whether you took them correctly (most PPIs work best 30 to 60 minutes before a meal).
Ask for findings in writing. If your ENT sees reflux changes, ask for the scope findings to go in the referral letter to GI. A gastroenterologist who reads “posterior laryngeal swelling and pseudosulcus” is much less likely to dismiss you on the basis of a normal esophagus.
Ask about objective testing. If the question is “is this reflux or not?”, a 24-hour impedance-pH study answers it far better than another opinion. Ask whether a study that includes a sensor high in the throat is available.
Ask “if this test is normal, what next?” It makes the specialist think beyond their own specialty and stops a normal result from becoming a dead end.
Ask for a laryngologist if you’ve already seen a general ENT and aren’t getting anywhere.
Let one doctor coordinate. Your GP or primary care doctor is usually best placed to keep both specialists’ findings together.

If you’d like help preparing for an appointment, working out which route fits your symptoms or making sense of your test results, I offer one-to-one consultations for exactly this.

Getting Seen: UK and US Routes

In the UK, you’ll normally go through your GP, who can refer you to an NHS ENT or gastroenterology clinic. Waiting lists can be long, so ask your GP which is most appropriate for your symptoms rather than being referred to both by default. If you go private, many ENT and GI consultants will see you with a GP letter, and it’s worth checking whether a laryngologist or voice clinic is available locally.

In the US, it depends on your insurance. With a PPO plan you can usually book an ENT or gastroenterologist directly. With an HMO you’ll need a referral from your primary care doctor. Academic medical centers often have dedicated voice and swallowing centers with laryngologists, speech pathologists and gastroenterologists working together, which is ideal for LPR.

My guide on when to see a doctor for LPR covers how long to try managing at home first, and what to expect at a GP appointment.

What to Do While You Wait

Specialist waits can be long, and there’s no reason to put your recovery on hold. Diet and lifestyle changes are first-line treatment for LPR, and they don’t stop a specialist from assessing you. A strict low-acid diet clearly improved symptoms in people with stubborn LPR [Koufman, Annals of Otology, Rhinology & Laryngology, 2011], and a plant-based Mediterranean-style diet with alkaline water worked as well as PPIs in another study [Zalvan et al., JAMA Otolaryngology–Head and Neck Surgery, 2017].

The basics:

Take the acid out of your diet for a few weeks. My Wipeout Diet Plan walks you through this step by step
Stop eating three hours before bed and raise the head of your bed
Take an alginate after meals and at bedtime. See alginates for acid reflux
Cut back on coffee, alcohol and fizzy drinks

One thing to check: if you’re booked for pH or impedance testing, you may be asked to stop acid-reducing medication for a week or two beforehand. Follow the clinic’s instructions, and don’t stop a prescribed medication without checking first.

When Not to Wait

Whatever route you take, see a doctor promptly, and ask for an urgent referral, if you have:

Hoarseness lasting more than three weeks, especially if you smoke
Difficulty swallowing that’s getting worse, or food sticking regularly
Unintentional weight loss
Coughing or vomiting blood, or black stools
A lump in your neck
Pain on one side of the throat or ear that won’t go away
Difficulty breathing or noisy breathing

Conclusion

For LPR, the ENT, and ideally a laryngologist, is usually the right first specialist, because your symptoms live in the throat and that’s where they can look. A gastroenterologist comes in when there’s heartburn, regurgitation, swallowing trouble or warning signs, or when you need proper reflux testing or a procedure. Many people with stubborn LPR benefit from both. The key is to stop a normal endoscopy or a “slightly red” throat from becoming a dead end. Go in prepared, ask for objective testing, and keep one doctor coordinating.

And don’t put your own recovery on hold while you wait. Most of what improves LPR happens at home, in what you eat and when you eat it. The Wipeout Diet Plan is where I’d start. It’s my complete, step-by-step plan for taking the acid out of your diet so pepsin stops irritating your throat, built from twelve years of living with LPR. It was built for silent reflux first, but because it works on the same root causes, it’s just as effective if your symptoms lean more towards heartburn and GERD.

If you’d like a lighter starting point, the Wipeout Food Reference Guide is the essential companion. It lists the foods and drinks that are safe for acid reflux and LPR with their pH values, so you can get started today while you wait for your appointment.

Frequently Asked Questions

Should I see an ENT or a gastroenterologist for LPR?

Start with an ENT, ideally a laryngologist, because LPR symptoms are in the throat and an ENT can examine your larynx and rule out other causes. See a gastroenterologist as well if you have heartburn, regurgitation, swallowing problems or warning signs, or if you need endoscopy, reflux testing or surgery.

What is a laryngologist?

A laryngologist is an ENT surgeon with extra training in the voice box, throat and swallowing. They see LPR every day, are more likely to use objective reflux testing, and are more familiar with non-acid reflux than general ENTs.

Why did my gastroenterologist say I don’t have reflux?

Usually because your endoscopy was normal and you don’t have heartburn. But LPR often causes neither, because the esophagus can tolerate reflux that irritates the more sensitive throat. A normal endoscopy doesn’t rule out LPR. A 24-hour impedance-pH study is the better test.

Can a gastroenterologist diagnose LPR?

They can measure reflux with pH and impedance testing, which is valuable evidence. But they don’t normally examine the larynx, so they can’t see throat changes or rule out other throat conditions. The best LPR diagnosis usually combines an ENT examination with objective reflux testing.

Do I need an endoscopy for LPR?

Not always. An endoscopy checks the esophagus and stomach, which matters if you have heartburn, swallowing problems, long-standing reflux, or warning signs like weight loss. For throat-only symptoms, a throat scope by an ENT is the more relevant first test.

What test proves LPR?

There’s no single perfect test. A 24-hour impedance-pH study, ideally with a sensor high in the throat, is the most objective way to show reflux reaching it. It’s usually combined with your symptoms, an ENT examination and how you respond to treatment.

Which doctor treats silent reflux in the UK?

Your GP is the first step and can refer you to an NHS ENT clinic for throat symptoms, or to gastroenterology if you also have heartburn, swallowing problems or warning signs. Some hospitals have voice clinics run by laryngologists and speech therapists, which are ideal for LPR.
