Difficulty swallowing that is persistent or getting worse needs urgent assessment — always. This is one of the clearest red-flag symptoms in medicine and it warrants an urgent endoscopy pathway, particularly with:
The urgent two-week-wait pathway for this is NHS only. Contact your NHS GP. We will write to them the same day.
Most symptoms on this site come with a discussion of when to worry. This one does not, because the answer is straightforward: persistent difficulty swallowing should always be assessed.
The reason is that the pattern of progression matters enormously, and the causes that need finding early are found by endoscopy rather than by waiting. Most turn out to be benign. The assessment is not optional regardless.
Common and benign
Structural and needing endoscopy — a benign stricture from long-standing reflux; eosinophilic oesophagitis, increasingly recognised in younger adults; achalasia; and oesophageal cancer, which is the reason this symptom is investigated rather than observed.
Neurological — stroke, Parkinson's and other conditions affecting the swallowing mechanism, usually with coughing or choking during meals.
New, persistent difficulty swallowing is one of the small number of symptoms that warrants investigation almost regardless of anything else. The advice below is for while you arrange that — not instead of it.
This one distinction shapes everything that follows, and it is something only you can report:
Note also whether food is sticking high in the throat or low behind the breastbone, and whether you have needed to change what you eat.
Weight loss alongside swallowing difficulty raises the urgency substantially, and it is much more persuasive as a number than an impression. Write it down with the date.
The most informative question is what you have difficulty with, and whether that has changed. Difficulty with solids that has progressed to soft food and then liquids is a different and more concerning pattern from difficulty that has been the same for years, or difficulty with liquids from the start.
The second is whether food actually sticks, and where you feel it stop. A sensation in the throat between meals behaves quite differently from food halting behind the breastbone.
We arrange full blood count and ferritin, since iron deficiency both causes swallowing difficulty and signals bleeding.
What matters most here is speed of referral, not remote treatment. Where the picture warrants urgent endoscopy we say so directly and write to your NHS GP the same day, because that pathway is NHS only. Privately, we can arrange endoscopy through a gastroenterology referral.
Genuinely urgent. New, persistent difficulty swallowing — particularly if it is progressive, if you are over 55, or if it comes with weight loss — warrants an urgent suspected-cancer referral for endoscopy. This is one of the clearest red-flag symptoms in medicine, and the reason is simple: oesophageal cancer causes no symptoms at all until it is large enough to narrow the gullet, so by the time swallowing changes, time matters.
Most people investigated for this do not have cancer. The investigation happens anyway, because the alternative is finding it later.
Solids sticking while liquids pass normally, getting steadily worse over weeks or months, points to a physical narrowing — a stricture from acid reflux, a ring, or a tumour. It is the pattern that needs endoscopy soonest.
Difficulty with both solids and liquids from the outset, coming and going, more often reflects a motility problem such as achalasia or oesophageal spasm. Still needs investigating, but a different set of causes.
No — that is globus, and it is a distinct and far more benign symptom. The key difference: globus is felt between swallows and often eases while eating, whereas true dysphagia is the experience of food itself sticking. Globus is common, frequently related to reflux or muscular tension, and does not carry the same urgency — though persistent globus with hoarseness or ear pain is still worth assessing.
It could — long-standing acid reflux is the commonest cause of a benign oesophageal stricture, and treating the reflux and stretching the narrowing resolves it. But that is a diagnosis made by looking, not by assuming, because reflux and oesophageal cancer produce very similar symptoms and reflux is itself a risk factor for it.
Yes, and this is worth understanding properly. Proton pump inhibitors such as omeprazole and lansoprazole are effective at relieving symptoms, including symptoms caused by a tumour. Someone who takes them for months, feels better, and therefore does not seek assessment can lose a great deal of time. New dysphagia should be endoscoped, not medicated and monitored.
A change in the lining of the lower gullet caused by years of acid reflux. It slightly raises the risk of oesophageal cancer, which is why people diagnosed with it are offered periodic surveillance endoscopy. If you have known Barrett's and your swallowing changes, that is a same-week conversation.
A thin flexible camera passed through the mouth into the gullet and stomach, taking around ten minutes, under throat spray or light sedation. It sees the lining directly, takes biopsies if needed, and can often treat a benign narrowing by stretching it in the same sitting. It is the test that settles this symptom, and it is far more tolerable than most people expect.
Partly, and the useful part is the referral. We can take a detailed history — which is what determines urgency here — arrange blood tests, and refer you for endoscopy privately, or write the same day to your NHS GP for the urgent two-week-wait pathway, which is NHS-only and often the right route. What we cannot do is examine your neck or perform the endoscopy, and this is a symptom where getting onto the right pathway quickly is the whole of the value.

Same-day access is usually available, from 6am to 10pm, seven days a week. You choose a time that suits you rather than waiting on hold at 8am.
Yes. Care is led personally by Dr Mohammad Khan, so you are not passed between clinicians. Continuity is the point of a small practice: someone who knows your history and is listening attentively rather than working through a checklist.
Yes, with your consent. We can access your Summary Care Record during the consultation, so your current medications, allergies and significant history are in the room. That means fewer questions you have already answered elsewhere, and safer prescribing.
No. We are not here to replace GPs, only to support them. Your NHS practice remains responsible for your ongoing care, and with your consent we write to them after the consultation. We are useful when you need to be seen sooner, or want more time than a standard appointment allows.
Twenty unhurried minutes and a comprehensive assessment. A written treatment plan is included, along with any prescription, sick note or referral letter arising from the consultation, at no extra charge.
£40 for 20 minutes, self-pay. Membership is optional and never required. Priced for fairness, because we are not here to charge extortionate amounts for access to a doctor.
It means the diagnosis can usually be made from your history and photographs, and that treatment can be arranged safely without examining you. Where a condition is not marked treatable online, it is because examination is the diagnosis — listening to a chest, feeling an abdomen, examining an ear or a joint — or because a procedure or device is needed.
Yes, where there is a genuine bacterial infection — cellulitis, impetigo, bacterial urine infections, confirmed strep throat. We will also frequently tell you that you do not need one. Most sore throats, coughs, colds and earaches are viral, and an antibiotic gives you the side effects with none of the benefit.
If your problem turns out to be genuinely outside what we can do remotely, the doctor will tell you straight away, point you to the right service, and refund your fee in full. We would rather do that than fill twenty minutes to justify the charge.
Call 999 or go to A&E — do not book an online appointment and do not wait for a reply to an email. For urgent problems that are not emergencies, NHS 111 is available 24 hours a day, online or by phone, and can direct you to the right service.
