When there is little or no insulin in the body, blood glucose levels can be excessively high, resulting in symptoms such as chemical imbalance, emotional pain and dizziness.
Low Glucose Levels
On the other hand, when insulin is oversupplied, glucose levels may drop to very low levels, also causing dizziness and other symptoms such as hunger, fatigue and anger.
Dizziness can be a side effect of blurred vision, which occurs when the liver must work overtime to maintain equilibrium in the body. The liver may produce sudden increases in glucose supply, affecting the retina because the blood vessels around it are oversupplied with glucose.
When there is an oversupply of glucose, the blood may often thicken, causing the veins around the heart to clog. When oxygen cannot travel fast enough through these veins, dizziness is a potential side effect.
Warning and Prevention
Fortunately, dizziness is your body's way of telling you that something is wrong. Help prevent this from happening by having blood sugar levels checked regularly, watching your diet, exercising and taking prescribed medications.
