There's no single "highest safe" level, but normal fasting blood sugar is under 100 mg/dL, prediabetes is 100-125 mg/dL, and diabetes is 126 mg/dL or higher; for most people without diabetes, levels under 140 mg/dL two hours after eating are good, while for those with diabetes, targets are often below 180 mg/dL, with levels consistently over 250 mg/dL signaling a need for medical attention, especially if ketones are present. Extremely high levels, like over 600 mg/dL, can indicate a severe emergency (Hyperosmolar Hyperglycemic State), notes Mayo Clinic.
