An incompetent cardia means the valve where your food pipe joins your stomach does not close tightly. Spanish endoscopy reports call it cardias incompetente. It can let stomach acid flow back up and cause reflux. It is a common finding, often with a small hiatus hernia. Most people do well with lifestyle changes and acid-lowering medicine.
- The cardia is the opening at the top of the stomach. A ring of muscle there normally keeps acid in.
- "Incompetent" means it looks loose or open on the camera test. It is a finding, not a diagnosis on its own.
- It is linked to reflux, heartburn and hiatus hernia, but some people have no symptoms.
- Treatment depends on your symptoms: meal timing, weight, raising the bed head and acid-lowering medicine.
- Surgery is kept for proven reflux disease that medicines do not control.
- Call 112 for chest pain with breathlessness, or for vomiting blood.

What does "cardias incompetente" mean on a Spanish endoscopy report?
A gastroscopy (gastroscopia or endoscopia digestiva alta) passes a thin camera down to your stomach. At the end of the food pipe there is a ring of muscle, the lower oesophageal sphincter. Mayo Clinic explains that it opens to let food in, then closes again.
When the doctor turns the camera back to look up at this opening, it should hug the tube closely. If it looks wide or loose, the report may say cardias incompetente, cardias laxo or cardias entreabierto. In English you may read "incompetent cardia", "lax lower oesophageal sphincter" or "open flap valve".
Some reports add a grade from the Hill system, from I to IV. An American Gastroenterological Association (AGA) expert review advises recording this grade in every reflux endoscopy. Grades III and IV mean the valve is looser.
Is an incompetent cardia the same as reflux disease?
No. It describes how the valve looks. Reflux disease is a diagnosis based on symptoms and other findings.
A loose valve does make reflux more likely. In one study from Korea, higher Hill grades went with more reflux damage to the food pipe and lower muscle pressure. But a 2024 US study found the grade does not reliably tell normal from abnormal reflux. So doctors look at the whole picture:
- Your symptoms, such as heartburn and acid coming up.
- Signs of damage, such as inflamed food pipe (esofagitis).
- Sometimes a pH test that measures acid in the food pipe over a few days.
The names differ by country. It is GERD in the US, GORD in the UK and ERGE in Spain.
How is it linked to a hiatus hernia?
A hiatus hernia is when part of the stomach moves up through the diaphragm into the chest. In the US it is called a hiatal hernia; in Spain, hernia de hiato. The NHS says it is very common over 50, in pregnancy and in people who are overweight.
A hernia stretches the opening, so the valve often closes less well. In the 2024 US study, 80% of people with Hill grade IV also had a hiatus hernia. The NHS says a hiatus hernia does not normally need treatment if it causes no problems.
What symptoms can an incompetent cardia cause?
Many people have none. When acid comes back up, the NHS and Mayo Clinic list:
- Heartburn, a burning feeling in the middle of the chest.
- A sour taste, or food and liquid coming back into the mouth.
- Pain in the upper belly.
- A cough, hoarse voice or hiccups that keep coming back.
- Bloating and feeling sick.
Symptoms are often worse after eating, when lying down or when bending over.
Can an incompetent cardia be treated?
Medicines do not tighten the valve. They reduce the acid that comes up. Treatment aims at your symptoms, not the report wording.
Daily habits. The NHS suggests you:
- Eat smaller meals, more often.
- Stop eating 3 to 4 hours before bed.
- Raise the head of your bed by 10 to 20 cm. Extra pillows are not advised, as they can press on your belly.
- Lose weight if you are overweight, and stop smoking.
- Cut down on your triggers, such as coffee, alcohol, chocolate, and fatty or spicy food.
- Avoid tight waistbands.
Pharmacy medicines. Antacids and alginates ease symptoms for a short time. The NHS says they should not be used regularly for long periods. Read about Almax, a common Spanish antacid.
Prescription medicines. Proton pump inhibitors (PPIs), such as omeprazole or esomeprazole, lower acid the most. H2 blockers such as famotidine are another option. See our guides to omeprazole in Spain and Nexium (esomeprazole).
Got an endoscopy report that says "cardias incompetente" and still have reflux?
You can book a video visit with a GP licensed in Spain, in English or Spanish. He goes through your report and symptoms with you and helps you plan the next steps.
Surgery. The AGA review says keyhole fundoplication works well for proven reflux disease. Here the top of the stomach is wrapped around the lower food pipe. It is offered only after tests confirm reflux, usually when other treatments have failed. The NHS notes bloating and swallowing trouble can take months to settle afterwards.
Is an incompetent cardia dangerous?
The finding itself is not dangerous. The risk comes from years of untreated acid. Mayo Clinic lists three problems:
- Oesophagitis: an inflamed food pipe that can bleed or ulcerate.
- Stricture: scarring that narrows the food pipe and makes swallowing hard.
- Barrett's oesophagus (esófago de Barrett): changes in the lining that raise the risk of cancer. It needs regular camera checks.
If your report mentions Barrett's or a grade of oesophagitis, ask your doctor what follow-up you need.
What about pregnancy and children?
Reflux is common in pregnancy. The NHS advises asking a pharmacist which medicines are safe. In babies and children, MedlinePlus notes a hiatus hernia is usually present from birth and often comes with reflux. If your child has reflux symptoms, talk to their doctor before giving any medicine.
When should you see a doctor?
Book a routine visit if:
- You have heartburn most days.
- Pharmacy medicines are not helping.
- You take non-prescription heartburn medicine more than twice a week. Mayo Clinic advises a check in that case.
See a doctor today if reflux comes with food sticking when you swallow, weight loss you cannot explain, frequent vomiting or upper belly pain. The same applies if you pass black, tarry poo.
Call 112 or go to urgencias if you have chest pain, especially with breathlessness or pain in the jaw or arm, as this may be a heart attack. Do the same if you vomit blood or something like coffee grounds, or if black, tarry poo comes with feeling faint or dizzy.
Talking it through with a doctor by video
Dr. Yelamo is a GP licensed in Spain. He sees adults, children and pregnant patients by video, every day from 07:30 to 20:30 (Spain time). In the visit he will:
- Read your endoscopy report with you and explain each term in plain English.
- Ask about your symptoms, medicines and warning signs.
- Agree a plan for habits and medicine, and tell you if you need a specialist (digestivo) or more tests.
He does not promise any test or prescription before the visit. Where clinically appropriate, following a genuine evaluation. Treatment and prescriptions are issued solely at the doctor's discretion based on evidence-based clinical guidelines.
A prescription is never guaranteed: it is issued only where clinically appropriate after a genuine evaluation, as a private electronic prescription under Spanish law. This service is for urgent, non-emergency care. In an emergency, call 112.
See how the Urgent Care video visit works. It lasts 15 minutes and costs €50.

Frequently asked questions
What does incompetent cardia mean?
It means the valve where the food pipe joins the stomach looks loose or open on a gastroscopy. It can let acid flow back up. It is a finding, not a diagnosis on its own.
Is incompetent cardia the same as a hiatus hernia?
No, but they often go together. A hiatus hernia is part of the stomach moving up into the chest. It stretches the opening, so the valve tends to close less well.
Can an incompetent cardia heal or close by itself?
Medicines do not tighten the valve. They lower acid so symptoms ease and the food pipe heals. Losing weight, if needed, and good meal habits also reduce reflux.
Do I need surgery for an incompetent cardia?
Usually not. Surgery is for proven reflux disease that other treatments do not control. Tests confirm reflux first.
What is the Hill grade on my report?
It is a score from I to IV for how well the valve closes. Grades III and IV mean a looser valve and are linked with more reflux.
When is reflux an emergency?
Call 112 for chest pain, especially with breathlessness or jaw or arm pain. Also for vomiting blood or coffee-ground material, or black, tarry poo with feeling faint or dizzy.
