A blood sugar level of 171 mg/dL is considered high, especially if measured after fasting or before meals. Here’s a breakdown of blood sugar ranges:

Blood Sugar Level (mg/dL) Category

Below 100 Normal (fasting) 100–125 Prediabetes
126 or higher Diabetes
140–199 (after meals) High (postprandial)

  • Fasting: A level of 171 mg/dL is above the normal range and may indicate diabetes or poor blood sugar control.
  • After Meals: While post-meal levels can be higher, 171 mg/dL is still elevated and should be monitored.

If you consistently see levels this high, consult your healthcare provider for further evaluation and management.
