Blood sugar, or glucose, is an important source of energy for the body. Your blood sugar level indicates how much glucose is in your blood, and this amount is constantly changing. Various factors, such as food, drink, exercise, stress, and emotions, influence your blood sugar level.

When the fluctuations are too great, you may experience high or low blood sugar levels (hyper or hypo). This can affect your mood, concentration, and energy levels. Too many hypos and hypers can also cause long-term damage, for example, to the eyes and cardiovascular system.

Stable blood sugar levels are therefore crucial for your overall health and energy balance. Fortunately, there's a lot you can do yourself. A balanced lifestyle and the right diet can contribute to maintaining stable blood sugar levels.

A healthy lifestyle and a varied, balanced diet are important.
