High blood sugar can affect brain function, causing issues with memory, focus, and decision-making. This phenomenon, often referred to as "brain fog," occurs when elevated glucose levels disrupt the brain's energy balance. Short-term effects include difficulty concentrating, recalling information, and staying organized. Patients may feel scatterbrained or overwhelmed by tasks that were once manageable. Chronic exposure to high blood sugar levels can have more serious consequences, including brain atrophy and vascular damage. These changes increase the risk of conditions like vascular dementia and cognitive decline. The constant stress of fluctuating glucose levels can also affect emotional regulation, leading to mood swings or irritability. Managing blood sugar through proper diet, exercise, and medication can significantly improve cognitive clarity and overall mental well-being.

4. Blurry Vision

Blurry vision is a common but often misunderstood symptom of high blood sugar. When glucose levels rise, excess sugar can seep into the eye's lens, causing it to swell. This swelling changes the lens's shape, making it difficult for the eyes to focus properly. The result is temporary blurry vision, which may worsen with prolonged periods of hyperglycemia. While this condition typically resolves when blood sugar levels stabilize, persistent or recurring blurry vision should not be ignored. Chronic hyperglycemia can lead to more severe complications, such as diabetic retinopathy. This condition damages the retina's blood vessels and, if left untreated, can result in vision loss. Patients should report any changes in vision to their doctor and consider regular eye exams to monitor for early signs of diabetic eye disease.
