High blood sugar (hyperglycemia) occurs when glucose levels rise above a healthy range, potentially leading to severe health risks if ignored.

Glucose fuels the body, supporting metabolism, brain function, and immunity. Insulin, produced by the pancreas, helps regulate glucose levels and directs it into cells for energy. Excess glucose is stored in the liver and muscles for later use.

The Dangers of High Blood Sugar

When blood sugar stays too high, it increases the risk of diabetes, heart disease, and kidney failure. Over time, it can damage blood vessels, nerves, and organs, leading to severe complications like strokes, vision loss, and amputations.

Common causes include insulin resistance, stress, illness, medications, and poor diet. Managing blood sugar is crucial for long-term health.
