đź§ 12 common signs your blood sugar may be too high

Your body tries to flush out excess glucose through urine. - Excessive thirst
Losing fluids makes you constantly feel dehydrated. - Increased hunger
Even after eating, your cells aren’t getting enough usable energy. - Fatigue or low energy
Glucose isn’t properly entering cells, leaving you feeling drained. - Blurred vision
High sugar levels can affect the lenses of your eyes. - Headaches
Often linked to dehydration or fluctuating glucose levels. - Slow-healing cuts or wounds
High sugar can impair circulation and immune response. - Frequent infections
Especially skin, gum, or urinary infections. - Dry mouth and itchy skin
