When your body has too much sugar in your blood, it tries to excrete it through urine. This leads to fluid loss and intense thirst.
2. Frequent urination (polyuria)
A classic warning sign: those affected have to go to the toilet several times during the night.
3. Unexplained weight loss
Especially in type 1 diabetes, sudden, severe weight loss occurs, even if you eat normally or even more.
4. Extreme fatigue
Because the body’s cells can’t absorb the sugar properly, energy is lacking. This leads to tiredness, listlessness, and exhaustion.
5. Blurred vision
High blood sugar levels change the fluid balance in the eye and temporarily impair vision
