How to Give Dietary Instructions in German to Diabetic Patients

Telling a patient with diabetes what to eat is one of the few conversations in nursing where the language itself carries the treatment. Get the words wrong and the patient eats the wrong thing. Get them right and nothing else is needed.

German diabetes education has its own vocabulary, its own units and its own tone. This guide covers all three.

The Core Vocabulary

GermanEnglish
der Diabetesdiabetes
der Blutzuckerblood glucose
das Insulininsulin
die Unterzuckerunghypoglycaemia, low blood sugar
die Überzuckerunghyperglycaemia, high blood sugar
die Kohlenhydratecarbohydrates
die Ballaststoffedietary fibre
das Vollkornbrotwholemeal bread
das Gemüsevegetables
das Obstfruit
die Süßigkeitensweets
die Mahlzeitmeal
der Zwischenmahlzeitsnack
das Sättigungsgefühlfeeling of fullness
das HbA1clong-term blood glucose marker

If you are preparing to work with German-speaking patients, learn German with clinical vocabulary taught in the situations where you will use it.

The Units: BE and KE

German diabetes education counts carbohydrate portions, and there are two competing units you will meet.

UnitGerman nameCarbohydrate per unit
BEBroteinheit12 grams
KEKohlenhydrateinheit10 grams

The Broteinheit is the older German convention and still appears in patient materials. The Kohlenhydrateinheit is more common in current clinical teaching. The two are different, they are not interchangeable, and mixing them up produces a real dosing error.

The safe sentence on a new ward is: "Rechnen wir hier mit BE oder mit KE?"

The Food Groups, in German

GermanEnglishNote for patients
Vollkornproduktewholegrain productsslower glucose rise
Hülsenfrüchtepulses, legumeshigh fibre, filling
Gemüsevegetableslow carbohydrate load
Obstfruitcontains fructose, count it
Milchproduktedairy productsnote the lactose
Fette und Ölefats and oilsno direct glucose effect
Zucker und Süßigkeitensugar and sweetsfast glucose rise
Alkoholalcoholcan cause delayed lows

How to Phrase the Advice

German nutrition advice is notably direct, and softening it too much makes you sound unsure. Three patterns carry almost everything.

Sollten for recommendation. "Sie sollten Vollkornbrot statt Weißbrot wählen." The Konjunktiv II form sollten is the standard way to advise without commanding.

The imperative for concrete instructions. "Essen Sie nicht direkt vor dem Schlafengehen." Clear and appropriate.

Je ... desto for consequences. "Je mehr Ballaststoffe Sie essen, desto langsamer steigt der Blutzucker." This structure is common in German patient education and worth mastering.

Twenty Sentences You Will Use

"Zählen Sie die Kohlenhydrate bei jeder Mahlzeit." - Count the carbohydrates at every meal.

"Wählen Sie Vollkorn statt Weißmehl." - Choose wholegrain instead of white flour.

"Achten Sie auf versteckten Zucker in Getränken." - Watch for hidden sugar in drinks.

"Essen Sie regelmäßig, nicht nur einmal am Tag." - Eat regularly, not just once a day.

"Vermeiden Sie zuckerhaltige Limonaden." - Avoid sugary soft drinks.

"Trinken Sie ausreichend Wasser." - Drink enough water.

"Alkohol kann später zu einer Unterzuckerung führen." - Alcohol can lead to low blood sugar later.

"Halten Sie immer Traubenzucker bereit." - Always keep glucose tablets with you.

"Bei Zittern, Schwitzen oder Heißhunger sofort etwas essen." - Eat something immediately if you shake, sweat or feel ravenous.

"Bewegen Sie sich nach dem Essen." - Move around after eating.

An illustrative ranking, not a clinical table. It is the shape of the message rather than the numbers that patients need.

Recognising a Low, in German

Half of diabetes teaching is teaching the patient to notice a hypo. The German symptoms are worth learning as a set, because patients will report them in exactly these words.

"Ich zittere." - I am shaking.

"Mir ist schwindelig." - I am dizzy.

"Ich schwitze plötzlich." - I am suddenly sweating.

"Ich habe Heißhunger." - I am ravenous.

"Ich bin plötzlich verwirrt." - I am suddenly confused.

If a patient says any of these, the German response is immediate: "Sie haben eine Unterzuckerung. Essen Sie jetzt etwas."

Three Mistakes Worth Avoiding

Mixing BE and KE. Establish the ward convention before you teach anything, and never switch units mid-conversation.

Using Latin or English food terms. Patients cook with German words. Linsen, Kohl, Graupen and Quark are the vocabulary the advice depends on.

Frightening instead of enabling. German patients respond better to "So halten Sie Ihren Blutzucker stabil" than to a list of prohibitions. The goal is control, not restriction.

Handling the Questions Patients Actually Ask

German diabetic patients ask the same handful of questions, and having an answer ready is what separates a lecture from a conversation.

"Darf ich noch Brot essen?" - Yes, with a defined amount: "Ja, zwei Scheiben Vollkornbrot zum Frühstück." "Was ist mit Obst?" - Fruit is a carbohydrate source and must be counted, not forbidden: "Obst ist erlaubt, aber es zählt mit." "Muss ich auf Alkohol verzichten?" - No, but it interferes with glucose control, so the honest answer is "Alkohol senkt den Blutzucker, deshalb nur in Maßen und nie auf nüchternen Magen."

Answering these well is not a matter of knowing more medicine. It is a matter of knowing the German phrasing well enough to answer while the patient is still listening, which is exactly what it means to learn German for patient education.

Turning Knowledge Into Instruction

Everything above is knowledge. What patients need from you is instruction: spoken, clear, repeated, and delivered in a way they can act on the same evening.
