A high sugar danger level is reached when blood glucose levels are dangerously elevated, posing serious health risks.
Understanding Dangerous Blood Sugar Levels
- Very Dangerous Levels: Two or more consecutive blood sugar readings of 300 mg/dL or higher are considered very dangerous and require immediate medical attention. These levels increase the risk of severe complications, such as diabetic ketoacidosis (DKA) and diabetic coma.
- Life-Threatening Levels: Blood sugar levels exceeding 600 mg/dL are life-threatening. This condition is called hyperglycemic hyperosmolar nonketotic syndrome (HHNS), which is an extreme hyperglycemic state.
Risks Associated with Dangerously High Blood Sugar
High blood sugar, also known as hyperglycemia, can cause a range of serious health problems if left untreated. Here are some of the most severe risks:
- Diabetic Ketoacidosis (DKA): This is a serious condition that develops when your body doesn’t have enough insulin to allow blood sugar into your cells for energy. As a result, your body starts breaking down fat for fuel, producing acidic chemicals called ketones. DKA symptoms may include difficulty breathing, fruity breath, nausea, and vomiting.
- Diabetic Coma: This is a life-threatening complication of diabetes. It occurs when your blood sugar becomes dangerously high or low and you lose consciousness.
- Hyperglycemic Hyperosmolar Nonketotic Syndrome (HHNS): This occurs when blood sugar levels get extremely high. With HHNS, the body tries to get rid of excess glucose through urine, leading to severe dehydration. Symptoms may include extreme thirst, confusion, weakness, and seizures.
What To Do
If you measure a blood glucose level at or above 300 mg/dL:
- Check for ketones using a urine or blood test, if instructed by your doctor.
- Stay hydrated.
- Consult a medical professional immediately.
Table: High Blood Sugar Danger Levels
| Level (mg/dL) | Condition | Risk |
|---|---|---|
| 300+ | Hyperglycemia | Very dangerous, risk of DKA and diabetic coma |
| 600+ | Hyperglycemic Hyperosmolar Nonketotic Syndrome (HHNS) | Life-threatening |
