Stress↗ can cause hormones to be released, which in turn stimulates the liver to generate more glucose, raising blood sugar levels.


The body can become less responsive to insulin as a result of inactivity, which raises blood sugar levels.

Bad diet

Consuming a diet rich in sugar and carbohydrates might increase blood sugar levels.


Some individuals may be predisposed genetically to having high blood sugar levels.
