Hiatus hernia living in teenagers

Overview

A hiatus hernia (hi-AY-tus HER-nee-uh) happens when part of the stomach pushes up through the diaphragm – the muscle that separates your chest from your belly – into the chest. Normally, the diaphragm helps keep stomach acid where it belongs. When the stomach moves up, acid can flow back into the food pipe (oesophagus), causing heartburn and other symptoms. In teenagers, this can be managed with simple changes and treatment.

Yes, hiatus hernias are fairly common in teenagers, though many don't realise they have one because symptoms are mild or absent. It becomes more common with age, but teens can be affected too.

Teenagers of any age can get a hiatus hernia. It is more likely if you are overweight, have a family history, or have certain conditions like chronic cough or frequent vomiting. It can also be present from birth (congenital).

Symptoms

Common symptoms

• Heartburn – a burning feeling in the chest or throat, often after eating or when lying down.
• Regurgitation – food or sour liquid coming back up into the mouth.
• Chest pain or discomfort, especially after meals.
• Feeling full quickly or bloating after eating.
• Burping or hiccups a lot.
• Nausea or vomiting.

Symptoms in children

• In younger children (under 12), symptoms may include spitting up, irritability during feeding, poor weight gain, or recurrent wheezing or coughing, especially at night.

Symptoms in older adults

• In older adults, symptoms can be more subtle: chronic cough, hoarseness, feeling of a lump in the throat (globus sensation), or frequent pneumonia from inhaling stomach acid during sleep.

Causes

Main causes

• Weakness in the diaphragm muscle at the opening where the food pipe passes through.
• Increased pressure in the belly, for example from being overweight, heavy lifting, chronic cough, or frequent vomiting.
• A congenital (present at birth) weakness in the diaphragm.

Risk factors

• Overweight or obesity – extra belly fat pushes on the stomach.
• Family history – having a parent or sibling with a hiatus hernia.
• Chronic constipation or straining on the toilet.
• Frequent heavy lifting (e.g., in sports or gym).
• Smoking or using e-cigarettes (which can cause coughing and weaken the diaphragm).
• Connective tissue disorders (like Ehlers-Danlos syndrome) that make tissues weaker.

When to see a doctor

See a doctor urgently if:

• If you have chest pain that is severe, crushing, or spreads to your arm, neck, or jaw – this needs immediate emergency care.
• If you vomit blood or have black stools.
• If you have trouble swallowing or feel food is stuck.

Book a routine appointment if:

• If heartburn, regurgitation, or other symptoms happen more than twice a week.
• If over-the-counter remedies (like antacids) don't help after a few weeks.
• If symptoms interfere with sleep, school, or daily activities.
• If you are losing weight without trying.

Diagnosis

A doctor will ask about your symptoms and examine you. They may also order tests to look at the stomach and food pipe to confirm the hernia and check for acid damage.

Tests that may be done

• Barium swallow X-ray – you drink a chalky liquid that coats your stomach and makes the hernia show up on X-rays.
• Endoscopy – a thin, flexible tube with a camera is passed down your throat to see the food pipe and stomach. This is done with sedation (medicine to help you relax).
• pH monitoring – a thin tube is placed in your food pipe to measure acid levels over 24 hours. This checks if acid reflux is happening many times.
• Manometry – a test that measures the pressure and movement of the food pipe.

What to expect at your appointment

If your symptoms point to a hiatus hernia, your doctor will explain the tests and what to expect. Most tests are quick and not painful. The results help decide the best treatment for you.

Treatment

Treatment for hiatus hernia in teenagers focuses on reducing acid reflux and easing symptoms. It often starts with changes in diet and habits. If that isn't enough, medicines can help. Surgery is rarely needed in teens, but it is an option for severe cases.

Self-care at home

• Eat smaller, more frequent meals instead of large ones.
• Avoid lying down for at least 2–3 hours after eating.
• Avoid foods and drinks that trigger reflux, like spicy foods, fizzy drinks, chocolate, and fried foods.
• Lose weight if you are overweight – even a small loss can help.
• Sleep with your head and shoulders raised (e.g., with extra pillows or a wedge).
• Avoid tight belts or clothing around the waist.
• Stop smoking or vaping – ask a doctor or nurse for help.

Medical treatments

If lifestyle changes aren't enough, doctors may recommend medicines that reduce stomach acid or help the stomach empty faster. These include medications called proton pump inhibitors (PPIs) and H2 blockers. Some teens use antacids for quick relief, but these should not be used long-term without medical advice. Always follow your doctor's instructions – never take more than recommended.

When is surgery considered?

Surgery (called fundoplication) is only considered if symptoms are severe and don't improve with lifestyle changes and medicines, or if there are complications like strictures (narrowing of the food pipe) or frequent aspiration pneumonia. The operation involves wrapping the top of the stomach around the food pipe to strengthen the valve. It is usually done with keyhole surgery, and recovery time is a few weeks.

Living with this condition

Living with a hiatus hernia as a teen means paying attention to what you eat and how you sleep. Most teens can manage symptoms well by following simple tips. It might take some trial and error to find what works for you.

Lifestyle tips

• Eat slowly and chew food well.
• Avoid eating within 3 hours of bedtime.
• Exercise regularly (but avoid heavy lifting just after eating).
• Manage stress – stress can make acid reflux worse.
• Keep a diary of your symptoms and triggers to share with your doctor.

Diet and exercise

Eat a balanced diet with plenty of fruits, vegetables, and whole grains. Avoid trigger foods like spicy, fatty, or acidic foods. Stay active – regular exercise helps with weight management and reduces pressure on the stomach. However, if you do exercises like sit-ups or heavy weightlifting, wait at least an hour after eating. Talk to your doctor or a sports coach about safe exercises.

Mental health and emotional wellbeing

Coping with a chronic condition like hiatus hernia can be frustrating. You might feel embarrassed about burping or heartburn in social situations. It's normal to feel worried or down sometimes. Talking to a trusted adult, a school counsellor, or a support group can help. Remember, you are not alone, and with the right management you can live a full and active life.

Prevention

Hiatus hernia cannot always be prevented, especially if it runs in your family. However, you can lower your risk by maintaining a healthy weight, avoiding heavy lifting without proper technique, managing chronic cough, and not smoking or vaping. If you already have a hernia, these steps can also prevent symptoms from getting worse.

Complications

If left untreated

• Oesophagitis – inflammation and damage to the lining of the food pipe from stomach acid.
• Oesophageal stricture – narrowing of the food pipe from scarring, making swallowing difficult.
• Barrett's oesophagus – a change in the cells of the food pipe that can increase the risk of cancer later in life (very rare in teenagers, but possible after many years).
• Recurrent aspiration pneumonia – getting stomach contents into the lungs, causing infection.
• Chronic cough, hoarseness, or asthma-like symptoms from acid irritating the throat and lungs.

Long-term outlook

For most teenagers, the outlook is excellent. With lifestyle changes and, if needed, medicines, symptoms can usually be well controlled. Even if surgery is required, it is effective and most teens return to normal activities within a few weeks. Serious complications are rare in this age group. Staying in touch with your healthcare team and following their advice will help you stay healthy and active.
