Blood sugar

What should your blood sugar be after eating?

October 5, 2026 · 5 min read

Blood sugar naturally rises after you eat and comes back down over the next few hours. For many non-pregnant adults with diabetes, the American Diabetes Association (ADA) suggests a goal under 180 mg/dL measured 1–2 hours after the start of a meal, and 80–130 mg/dL before meals. Your own goals may be different.

How to check after a meal

  • Wash and dry your hands before testing.
  • Note the time you started eating, then check 1–2 hours later.
  • Write down what you ate — patterns become clearer over a week.
  • Use the glucose-timing tag in Today's Vitals so before-meal and after-meal readings are not mixed up.

When to contact your provider

  • Readings often above your target.
  • Any reading under 70 mg/dL, or symptoms like shakiness, sweating or confusion.
  • Very high readings with thirst, frequent urination or feeling unwell.
