Summary
3 papers analyzed
These studies suggest that both very low (hypoglycemia) and high (hyperglycemia) blood sugar levels can be dangerous, with risks varying by age, race, ethnicity, and insurance status, and that high blood sugar levels are particularly associated with cardiovascular mortality.

Understanding Dangerous Blood Sugar Levels
High Blood Sugar Levels: Hyperglycemia
Risks and Complications of Hyperglycemia
Hyperglycemia, or high blood sugar, is a hallmark of diabetes and can lead to severe complications if not managed properly. Persistent high blood sugar levels can damage vital organs, including the heart, eyes, and kidneys, and increase the risk of cardiovascular diseases such as ischemic heart disease and stroke. The global burden of cardiovascular mortality attributable to high blood glucose is significant, with millions of deaths annually, particularly in low-and-middle-income countries.
Blood Glucose and Cardiovascular Mortality
Research indicates that cardiovascular mortality risk increases continuously with blood glucose levels, even below the conventional thresholds for diabetes diagnosis. This underscores the importance of maintaining blood glucose within an optimal range to prevent cardiovascular diseases and related deaths.
Low Blood Sugar Levels: Hypoglycemia
Dangers of Hypoglycemia
While much attention is given to the dangers of high blood sugar, low blood sugar, or hypoglycemia, is equally dangerous. Hypoglycemia can lead to severe health issues and requires immediate medical attention if blood sugar levels drop too low. Symptoms of hypoglycemia include shakiness, confusion, and in severe cases, loss of consciousness or seizures.
Hospitalizations Due to Hypoglycemia
Studies have shown an increase in hospitalizations due to hypoglycemia among diabetic patients, particularly among older adults, females, and certain ethnic groups. This trend highlights the need for better education on managing blood sugar levels, recognizing hypoglycemia symptoms, and early intervention to prevent severe outcomes.
Conclusion
Both hyperglycemia and hypoglycemia pose significant health risks. High blood sugar levels are associated with long-term complications and increased cardiovascular mortality, while low blood sugar levels can lead to immediate, life-threatening conditions. Effective diabetes management, including regular monitoring and education on recognizing and treating abnormal blood sugar levels, is crucial to minimize these risks.
