Dr. Chrysoula I. Liakou MD, PhD
- Treated online: Yes, usually. Gastritis is diagnosed from the story by video, an H. pylori stool or breath test arranged, and a time-limited acid-suppressing course or eradication treatment prescribed; vomiting blood, black stools, trouble swallowing or weight loss need in-person investigation first.
- What it is: inflammation of the stomach's protective lining, acute after alcohol, painkillers or a severe illness, or chronic with H. pylori infection (carried by about 1 in 3 European adults) or an autoimmune attack on the lining; it affects most people at some point.
- How long: symptoms often ease within days of removing the trigger and starting acid suppression, but the lining takes 4 to 8 weeks to heal, so courses run that long; H. pylori eradication is a 1 to 2 week course, re-tested 4 weeks after.
- Test and treat: a stool antigen or urea breath test finds H. pylori without a clinic visit, with acid-suppressing tablets stopped 2 weeks beforehand so the result is not falsely negative; eradication cures the gastritis and prevents ulcers in about 9 in 10 people.
- Painkillers: anti-inflammatory painkillers and aspirin are the commonest avoidable cause; paracetamol does not inflame the stomach, and anyone who must stay on an anti-inflammatory takes stomach protection alongside it.
- Emergency: call 112 or go to emergency care if you vomit blood or coffee-ground material, pass black tar-like stools, or have severe abdominal pain with a rigid belly, which are beyond gastritis and beyond a video call.
If you are vomiting blood or material that looks like coffee grounds, passing black tar-like stools, or have severe abdominal pain with a rigid belly, this is beyond gastritis and beyond a video call: call 112 or go to emergency care now. Difficulty swallowing, food sticking, or unexplained weight loss also need urgent in-person investigation rather than an online prescription.
Can an online doctor treat gastritis?
Yes, in most uncomplicated cases. Gastritis, inflammation of the stomach lining, is usually diagnosed from a careful history and treated by removing the trigger, testing for H. pylori where appropriate, and a time-limited course of acid-suppressing medication.[1] All of that can be organised by video. Alarm features such as bleeding, swallowing difficulty or weight loss need endoscopy.
What an online doctor will not do is guess. Burning upper-stomach pain has several look-alike causes, and the consultation is designed to separate them before anything is prescribed.

How an online consultation helps with gastritis
- Finding the actual trigger: the doctor goes through your painkillers, alcohol pattern, smoking and recent illnesses line by line, because gastritis treatment that ignores the cause is a subscription to symptoms.
- The H. pylori pathway, organised: if testing is appropriate, the doctor directs you to the right test locally (stool antigen or breath test), explains how to prepare for it so the result is valid, and prescribes eradication treatment if it is positive.[1]
- Honest medication plans: acid-suppressing tablets are used properly: right dose, defined duration, planned review, rather than an open-ended repeat.
- A clear line to endoscopy: if your age, symptoms or alarm features mean the guideline answer is a camera test, the doctor says so at the first consultation and refers you, instead of treating blind.[3]
What the doctor checks in an online gastritis consultation
Gastritis is a history-driven diagnosis, which is exactly why it suits video assessment. The doctor will typically establish:
- The pain itself: where it sits, whether it burns or gnaws, its relation to meals, whether it wakes you, and how long it has been going on.
- Medicines that inflame the stomach: ibuprofen, naproxen, diclofenac and aspirin are the classic culprits, including the doses hiding in cold remedies and gels; steroids and some other drugs add to the risk.
- Alcohol, smoking and recent stressors: heavy or binge drinking is a direct chemical irritant; severe physical illness can inflame the stomach lining too.
- Associated symptoms: nausea, bloating, early fullness, vomiting, and any sign of bleeding, including stools darker than usual.
- Alarm features, asked directly: trouble swallowing, food sticking, unintended weight loss, repeated vomiting, anaemia symptoms such as unusual tiredness and breathlessness. Any of these moves you to an endoscopy pathway rather than online treatment.[3]
- Whether H. pylori testing is due: based on your symptom pattern, history and what testing you have already had.
- What you have already tried: antacids, pharmacy remedies, previous acid-suppressing courses, and what each did.
What causes gastritis?
Painkillers and alcohol
Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, naproxen and aspirin reduce the stomach's protective mucus layer, leaving the lining exposed to its own acid. Taken regularly, at high doses, or on an empty stomach, they are one of the commonest causes of gastritis and of the stomach ulcers it can progress to.[1] Alcohol works more crudely, as a direct irritant: a heavy weekend can inflame a healthy stomach, and sustained heavy drinking keeps it inflamed.
H. pylori infection
Helicobacter pylori is a bacterium that colonises the stomach lining, usually from childhood, and is one of the most common chronic infections in the world. Most carriers never notice it, but in some people it drives persistent gastritis, ulcers and, over decades, a raised risk of stomach cancer, which is why guidelines recommend testing for it in persistent unexplained upper-stomach symptoms and eradicating it when found.[1][2]
Less common causes
Autoimmune gastritis (where the immune system attacks the stomach lining, affecting vitamin B12 absorption), bile reflux after stomach surgery, and severe physiological stress from critical illness are rarer causes the doctor keeps in mind, particularly when the story does not fit the usual triggers.
How does H. pylori test-and-treat work?
Test-and-treat means exactly that: confirm the infection with a reliable test, treat it with a short combination course, and confirm the problem is gone rather than assuming. It is the guideline-recommended route for persistent dyspepsia and suspected H. pylori gastritis without alarm features.[1][2]
The practical steps matter. The usual tests are a stool antigen test or a urea breath test; blood antibody tests are less useful because they stay positive long after the infection is gone. Acid-suppressing tablets must be stopped for about two weeks before testing, and antibiotics for four, or the test can read falsely negative.[1] Eradication treatment is a roughly one-week course combining two antibiotics with an acid-suppressing tablet; this is one of the situations where antibiotics are genuinely indicated, prescribed against a confirmed bacterial target rather than on suspicion.[5] Take the full course exactly as prescribed, because half-finished courses breed resistant bacteria and failed eradication. Where symptoms persist afterwards, a retest (again with the two-week medication gap) settles whether the infection is cleared or needs a second, different combination. An online doctor can direct the whole sequence, including where you collect the test.
Is my gastritis suitable for online care?
Usually yes, and the exceptions follow clear rules. This is the decision framework the doctors use, aligned with the cited guidance.

| Presentation | Likely first step | Suitable for online care? | When referral or in-person care is needed |
|---|---|---|---|
| Burning upper-stomach pain linked to NSAIDs or alcohol | Remove the trigger; 4–8 week acid-suppressing course[1] | Usually yes | No improvement after a proper course, or trigger cannot be stopped safely |
| Persistent or recurring symptoms without alarm features | H. pylori test-and-treat pathway | Usually yes | Persistent symptoms after eradication and an adequate PPI trial |
| Long-term NSAID or aspirin user who needs to continue | Review with prescriber; stomach-protection strategy | Often yes | Any bleeding sign, or complex medication decisions needing your specialist |
| Alarm features: swallowing difficulty, weight loss, repeated vomiting, anaemia | Urgent endoscopy referral[3] | Assessment and referral only | Always: these need investigation, not blind treatment |
| Vomiting blood or coffee-ground material, black tarry stools | Emergency care | No | Call 112 or go to emergency care immediately |

What you can do yourself
Stop the irritants you control: pause NSAID painkillers (paracetamol is the safer stand-in for most people), cut alcohol right down or out while the lining heals, and take seriously the fact that smoking slows that healing. Smaller meals, eaten earlier in the evening, sit more comfortably on an inflamed stomach, and pharmacy antacids or alginates give short-term relief while the underlying plan works. If an anti-inflammatory was prescribed to you, do not simply stop it: tell the doctor, who weighs the reason you take it against the stomach it is inflaming.
Prescription treatment, with PPI honesty
A prescription is never issued without a consultation. The workhorse treatment is a proton pump inhibitor (PPI) such as omeprazole, taken as a defined 4–8 week course to let the lining heal, sometimes preceded or replaced by an H2 blocker such as famotidine.[1][4] Two honest notes belong here. First, PPIs are excellent healers but poor exits: stopping suddenly after long use can cause a rebound surge of acid that mimics relapse, so longer courses are stepped down rather than dropped. Second, a PPI is not meant to be a permanent answer to an unexamined symptom: guidelines are clear that persistent need for acid suppression should prompt H. pylori testing, a look at the trigger, and periodic review at the lowest effective dose, not an automatic repeat.[1][2] If H. pylori is confirmed, eradication treatment as described above deals with the cause rather than muffling it.
When it might be something else
Gastritis shares its postcode with several conditions, and part of the consultation is telling them apart. Pain that gnaws when the stomach is empty and eases with food leans towards a stomach or duodenal ulcer. Burning that rises behind the breastbone with an acid taste is reflux, covered on the GORD page. General meal-related discomfort without inflammation may be functional indigestion, which overlaps but is managed differently. Pain boring through to the back with vomiting raises the pancreas; right-sided pain after fatty food raises gallstones. And crushing central chest pressure is a heart question, not a stomach one, which is why the doctor asks about it directly.
When gastritis is treated online, and when you need in-person care
Treated online: trigger-related gastritis (NSAIDs, alcohol) with a clear plan and a defined acid-suppression course; H. pylori testing, eradication treatment and retesting; stomach-protection reviews for people who must stay on anti-inflammatories or aspirin; and follow-up when a previous course has not fully settled things.
In-person care: anyone with alarm features (difficulty swallowing, food sticking, unintended weight loss, persistent vomiting, signs of anaemia) goes on an urgent endoscopy pathway, in line with European referral guidance;[3] symptoms persisting despite eradication and an adequate treatment trial need gastroenterology assessment; suspected autoimmune gastritis needs blood work-up in person; and any sign of bleeding is an emergency, not a consultation. In those cases the video appointment buys you the right referral at the first step, with a full refund if your doctor decides you need to be seen in person.
When to get in-person care
Call 112 or go to emergency care immediately if you vomit blood or coffee-ground material, pass black tar-like stools, have severe abdominal pain with a rigid belly, or feel faint and sweaty with stomach pain, which can also signal a heart problem. Arrange urgent in-person investigation, within days not weeks, for difficulty swallowing, food sticking, unintended weight loss or repeated vomiting.
Treating gastritis at home: what helps and what does not
Mild gastritis often settles with home care: smaller meals, easing off alcohol, coffee and smoking, avoiding anti-inflammatory painkillers that irritate the stomach lining, and pharmacy antacids for the burn while things calm down.
What home care cannot do: it cannot test for Helicobacter pylori, the stomach infection behind much persistent gastritis, and it cannot heal an ulcer. Pain that keeps returning, symptoms beyond a couple of weeks, or gastritis alongside regular painkiller use deserves diagnosis and often prescription treatment. Black tarry stools or vomiting blood is an emergency, not a diet question.
The strongest at-home treatment is still a doctor. A video consultation brings one to your sofa: an honest assessment, and a prescription to a local pharmacy when treatment is right. You can see a doctor over video, usually within 15 minutes. Book a video consultation: the exact price is shown before you pay.

Frequently asked questions about gastritis
What is gastritis, and what causes it?
Gastritis is inflammation of the stomach lining, the mucous layer that protects the stomach from its own acid. It is caused most often by anti-inflammatory painkillers and aspirin, alcohol, and infection with Helicobacter pylori; less often by the physical stress of major surgery or critical illness, bile flowing back into the stomach, smoking, an autoimmune attack on the lining, or viral infection. Everyday stress does not cause it on its own.
What are the symptoms of gastritis?
Gastritis causes a gnawing, burning or aching pain in the upper middle abdomen, often worse on an empty stomach or after meals, with nausea, bloating, early fullness, belching, loss of appetite and sometimes vomiting. Many people with gastritis, especially from H. pylori, have no symptoms at all. Vomiting blood, black stools, difficulty swallowing or weight loss are not gastritis symptoms and need urgent assessment.
Can an online doctor prescribe gastritis treatment in Europe?
Yes, after a video consultation: a time-limited acid-suppressing course for gastritis, a switch away from the painkiller causing it, and H. pylori eradication treatment where a test confirms the infection, with the prescription sent to a pharmacy near you. A prescription is never issued without a consultation, and alarm features are sent for endoscopy before any treatment is started.
How is H. pylori tested without visiting a clinic?
The usual options for gastritis are a stool antigen test, collected at home and dropped at a laboratory, or a urea breath test done at a laboratory or pharmacy; the doctor tells you where to arrange them. Stop acid-suppressing tablets about two weeks beforehand and antibiotics four weeks beforehand, or the result can be falsely negative, and a repeat test four weeks after treatment confirms the infection has gone.
How long does gastritis take to heal?
With the trigger removed and treatment started, gastritis symptoms often ease within days, but the lining itself typically needs several weeks to heal, which is why acid-suppressing courses run four to eight weeks. Stopping tablets the day you feel better is the classic way to boomerang back. H. pylori gastritis clears once the bacterium is eradicated, and autoimmune gastritis is long-term and monitored rather than cured.
Do I need an endoscopy for gastritis?
Usually not at first. Endoscopy for gastritis is for alarm features (trouble swallowing, weight loss, bleeding signs, persistent vomiting, a mass or anaemia), for symptoms that persist despite proper treatment and a negative or treated H. pylori test, and for some patients based on age and family history. The doctor says plainly which group you are in and refers you where it is needed.
Is gastritis the same as an ulcer?
No. Gastritis is inflammation of the stomach lining; an ulcer is a deeper break in it, in the stomach or the first part of the small intestine. Untreated gastritis, especially with anti-inflammatory painkillers or H. pylori on board, can progress to an ulcer, which can bleed or perforate, which is why finding and removing the cause of gastritis matters more than muffling the symptoms.
Can stress cause gastritis?
Everyday stress does not inflame the stomach lining by itself, though it can worsen how gastritis symptoms feel and drive the habits that do cause it: alcohol, painkillers, smoking and skipped meals. Severe physical stress, major surgery, burns or critical illness can cause stress gastritis with bleeding, but that is a hospital problem. Treating stress helps symptoms; treating the cause heals the lining.
What should I eat with gastritis?
With gastritis, eat small regular meals, choose plain food such as oats, rice, bananas, cooked vegetables, lean protein and yoghurt, and avoid alcohol, coffee, fizzy drinks, very spicy, fried or acidic food and late large meals until the lining has healed. No diet cures gastritis, and a bland diet is not needed for life, but removing the irritants while the acid treatment works speeds healing.
What can I do at home for gastritis?
At home, stop anti-inflammatory painkillers and aspirin unless prescribed for a reason, use paracetamol instead, stop alcohol and smoking, eat small regular meals, avoid the foods that reliably sting, do not lie down within three hours of eating, take the prescribed acid treatment for the full course even once pain has gone, and arrange the H. pylori test; pharmacy antacids give short relief from gastritis pain meanwhile.
How can I prevent gastritis coming back?
Prevent gastritis by using paracetamol rather than anti-inflammatory painkillers for everyday pain, taking stomach protection if an anti-inflammatory or aspirin is essential, limiting alcohol, not smoking, eating regularly, completing H. pylori eradication and confirming it with a re-test, and washing hands and food well, since H. pylori spreads between people and through contaminated food and water.
What complications can gastritis cause?
Untreated gastritis can lead to stomach or duodenal ulcers, bleeding (seen as black stools or vomited blood), anaemia from chronic blood loss, and, with autoimmune gastritis, vitamin B12 deficiency. Long-standing H. pylori gastritis slightly raises the risk of stomach cancer over decades, which is a reason to eradicate the infection rather than suppress acid indefinitely; eradication lowers that risk.
Is gastritis different in pregnancy or in older people?
In pregnancy, gastritis-type symptoms are common from reflux and pressure, antacids and some acid-suppressing tablets are considered suitable after a consultation, and H. pylori eradication usually waits until after the birth. In older people, gastritis is more often from aspirin or anti-inflammatory painkillers, bleeds more easily, and new symptoms after 55 with weight loss or anaemia are investigated by endoscopy rather than treated blind.
