Quick answer

Heartburn arises when stomach acid flows back into the oesophagus and irritates its sensitive mucous membrane. Small, low-fat meals, calm eating, a time gap before sleep and fewer triggers such as alcohol, coffee or heavily seasoned food help in everyday life. With frequent or severe heartburn you should have it medically clarified.

Almost everyone knows heartburn: a burning sensation behind the breastbone that can rise up into the throat, often accompanied by acid reflux. Behind it is refluxing stomach acid that irritates the sensitive mucous membrane of the oesophagus. Occasional heartburn is usually harmless and is connected with heavy meals, stress or certain foods. With a few adjustments to eating, pace and daily rhythm, a lot can often already be achieved. When frequent heartburn should be examined by a doctor and what role nutrition and a balanced gut flora play, you can read here.

What is behind heartburn?

Between the oesophagus and the stomach lies a ring-shaped muscle that normally, like a valve, prevents stomach contents from flowing back up. If this closure slackens or the pressure in the abdomen rises, acidic stomach contents reach the oesophagus. Its mucous membrane, unlike the stomach, is not well protected against acid, which is why the typical burning arises. Professionally, this is called reflux.

Heartburn is favoured by large, high-fat meals, hasty eating, late eating shortly before going to bed, excess weight, stress as well as by certain stimulants. Frequently mentioned are alcohol, coffee, very spicy or heavily seasoned food, chocolate and carbonated drinks. Tight clothing and lying flat after eating can also promote the reflux. In many people, several of these factors come together.

It is worth distinguishing between occasional and frequent heartburn. A one-off burning after a heavy meal or a glass of wine is something different from recurring symptoms that occur several times a week. Pregnancy, too, is a typical phase in which heartburn occurs more frequently, because the pressure in the abdomen changes. This form usually subsides again after the birth. Those who are permanently affected, on the other hand, should not simply put up with the symptoms, but have the cause clarified by a doctor instead of covering them up over a long time with home remedies.

When you should have it medically clarified

Occasional heartburn is usually harmless. You should seek medical advice if the heartburn occurs frequently, for example several times a week over a longer period, if it does not improve despite changed habits, if difficulty swallowing, pain when swallowing, unintentional weight loss, recurring vomiting or blood in vomit or stool are added. Nocturnal symptoms, chronic cough or hoarseness should also be examined. Important: burning or pressure behind the breastbone can also have other causes, which is why in the case of sudden, severe symptoms or symptoms radiating into the arm, jaw or back, immediate medical help is necessary. In the case of persistent or unusual symptoms, medical advice is always the right decision.

What helps in everyday life

Simple habits often bring noticeable relief. Prefer to eat several small meals instead of a few large ones and chew calmly, because hasty eating and a full stomach increase the pressure and favour the reflux. Consciously allow yourself some time for meals and avoid doing heavy physical work or lying down flat directly after eating. Let about three hours pass between the last meal and going to bed, so that the stomach can empty. A slightly raised head of the bed can reduce nocturnal symptoms, because gravity makes the reflux more difficult.

Pay attention to your body weight, as excess abdominal fat increases the pressure on the stomach. Avoid tight belts and observe which foods trigger symptoms in you, because the triggers are individual. A food and symptom diary helps to recognise personal triggers. Stress reduction also plays a role, because tension can influence digestion.

A food and symptom diary is often more revealing than expected. Note over one to two weeks what and when you eat and when symptoms occur. In this way patterns can be recognised, for example that certain foods only cause problems in combination with late eating or stress. Drinking behaviour also comes into play: larger amounts at once, especially of carbonated or alcoholic drinks, are more of a burden than small sips of still water spread over the day. Those who smoke should know that nicotine can additionally weaken the lower oesophageal closure. Small, consistently implemented changes often bring more here than a single drastic measure.

Nutrition with heartburn

Nutrition is the most important lever. Well tolerated for many people are low-fat, mild foods such as porridge, steamed vegetables, potatoes, lean poultry, fish, bananas and still water. Frequent triggers, on the other hand, are very fatty and fried dishes, heavily seasoned food, sour citrus fruits, tomatoes in large quantities, coffee, alcohol, chocolate and carbonated drinks. Since tolerability is individual, it is worth observing your own reactions. A fibre-rich, plant-focused diet additionally supports healthy digestion overall. The way of preparation also makes a difference: steamed, boiled or mildly fried food is usually better tolerated than sharply seared or deep-fried food. Those who like to season can choose mild herbs instead of hot spices and observe how the body reacts to it. Small portions, eaten calmly, are almost always more digestible than large amounts in a hurry.

Gut flora and digestion

A balanced digestion begins well before the oesophagus and encompasses the entire gastrointestinal tract. The gut is home to trillions of bacteria that play an important role in digestion. A fibre-rich diet with vegetables, fruit, wholegrain products and fermented foods such as yoghurt or sauerkraut supports a diverse gut flora. Sufficient fluid and regular exercise additionally promote digestion. These general measures do not directly target the stomach acid, but contribute to an overall balanced digestive system.

One should not misunderstand the role of stomach acid here. Acid is desired and important in the stomach, because it helps to break down food and protects against germs. The problem with heartburn is not the acid itself, but its reflux to the wrong place, the sensitive oesophagus. That is why the sensible everyday measures primarily start with reducing this reflux, for example through timing, portion size and posture. A healthy, balanced diet supports digestion as a whole and is the best foundation, but in the case of frequent or severe symptoms is no substitute for the medical clarification of the cause.

Honestly classified

There is no single miracle cure against heartburn. The most effective way is the combination of adapted nutrition, calm eating, good timing of meals, weight control and stress reduction. Food supplements and probiotic cultures can complement a balanced diet, but they are no substitute for these habits and no treatment for frequent or severe heartburn. If heartburn occurs regularly, the cause belongs to be clarified professionally instead of permanently covering it up yourself.

Precisely because many of those affected reach for over-the-counter remedies, this note is important: anyone who regularly reaches for acid-inhibiting preparations over weeks to suppress symptoms should have this medically accompanied. Persistent heartburn can strain the oesophagus in the long term, which is why a precise examination is more sensible than permanent self-treatment. In many cases, consistently implemented everyday changes already bring noticeable relief, so that the frequency of the symptoms decreases noticeably. Patience and an honest assessment of one's own habits are often the key here.

Matching products

Anyone who would like to complement their nutrition in the area of gut flora will find with us, among other things, a cultures complex with various bacterial strains and a high number of cultures per portion. Such products provide live cultures and complement a fibre-rich, balanced diet, but do not replace it and are no remedy against acute heartburn.

Frequently asked questions (FAQ)

What triggers heartburn most frequently?

Typical triggers are large, high-fat meals, hasty and late eating, alcohol, coffee, heavily seasoned food, chocolate and carbonated drinks. Excess weight, stress and lying flat after eating can also favour the reflux of stomach acid.

Which foods are well tolerated with heartburn?

Many people tolerate low-fat, mild foods such as porridge, steamed vegetables, potatoes, lean poultry, fish, bananas and still water well. Since tolerability is individual, a food diary helps to recognise your own triggers and well-tolerated foods.

Does it help to raise the bed?

A slightly raised head end can reduce nocturnal symptoms, because gravity makes the reflux of stomach acid more difficult. In combination with a gap of about three hours between the last meal and going to bed, this often has a relieving effect.

When should I see a doctor with heartburn?

Seek medical advice if heartburn occurs frequently, persists despite changed habits or if difficulty swallowing, weight loss, recurring vomiting or blood are added. In the case of sudden, severe or radiating chest pain, immediate help is necessary.

Can probiotic cultures help with heartburn?

Probiotic cultures support a diverse gut flora and complement a balanced diet. They are, however, no remedy against acute heartburn and no substitute for adapted eating habits or a medical examination in the case of frequent symptoms.
