Reasons for High Blood Glucose Levels

High blood glucose levels can arise from both pathological and physiological reasons. Pathological causes include consuming refined sugars and carbohydrates, leading to elevated A1c levels and glycation, which damages proteins and can adversely impact various body systems. Physiological causes, on the other hand, such as infection, injury, inflammation, stress, or lack of sleep, can temporarily increase blood glucose levels. Additionally, factors like artificial sweeteners, excessive caffeine, intense exercise, menstrual cycle, certain medications, and fasting may also contribute to elevated blood glucose levels. However, it is important to note that these physiological causes typically do not result in pathological outcomes or high A1c levels.
