how high can a blood sugar get

Blood sugar levels can vary significantly depending on individual health conditions, but extremely high levels can be dangerous. Here’s a general overview:

• Normal Range: 70–99 mg/dL (fasting)
• Prediabetes: 100–125 mg/dL (fasting)
• Diabetes: 126 mg/dL or higher (fasting)

In severe cases, blood sugar levels can exceed 600 mg/dL, leading to a life-threatening condition called diabetic hyperosmolar syndrome. Symptoms include extreme thirst, confusion, and dehydration. If blood sugar levels are extremely high, seek immediate medical attention.

Always consult your healthcare provider for personalized advice and management.
