blood sugar
The concentration of glucose (grape sugar) in the blood. The blood sugar level is an important medical value whose regulation is crucial for metabolism.
Diabetiker müssen regelmäßig ihren Blutzucker messen, um ihn richtig einzustellen.
Diabetics have to measure their blood sugar regularly in order to manage it properly.
The word is a direct compound of 'das Blut' (blood) and 'der Zucker' (sugar). So it literally describes the sugar that is found in the blood.
Nach dem Essen von Süßigkeiten steigt der Blutzucker schnell an.
After eating sweets, blood sugar rises quickly.
Common verbs are 'den Blutzucker messen' (to measure blood sugar), 'senken' (to lower), or 'kontrollieren' (to monitor/control). Blood sugar can be 'hoch' (high) or 'niedrig' (low), and it can 'steigen' (rise) or 'sinken' (fall).
Sport kann dabei helfen, den Blutzucker zu senken.
Exercise can help lower blood sugar.
Very often, instead of just 'der Blutzucker' (blood sugar), the more precise expression 'der Blutzuckerspiegel' (blood sugar level) is used to describe the level of glucose in the blood.
Der Arzt möchte meinen Blutzuckerspiegel überprüfen.
The doctor wants to check my blood sugar level.

In a medical context, „Zucker“ can colloquially mean blood sugar. „Blutzucker“ is the more precise term and immediately makes it clear that the concentration of glucose in the blood is meant. Use „Zucker“ only when the context is unambiguous; otherwise, „Blutzucker“ is more appropriate.
Beim Arzt sagte meine Mutter, dass ihr Blutzucker heute etwas erhöht ist.
At the doctor's, my mother said that her blood sugar was slightly elevated today.
Beim Arzt sagte meine Mutter, dass ihr Zucker heute etwas erhöht ist.
