Postprandial blood sugar on your report

Often written as PPBS or PP glucose, in mg/dL.

Targets:

  • For most non-pregnant adults with diabetes, CDC gives a target below 180 mg/dL one to two hours after meals.
  • Your own target and your lab's range may differ, so ask your doctor what applies to you.

Postprandial blood sugar: your blood glucose measured after a meal, usually about two hours after you start eating.

What postprandial blood sugar tells your doctor

Some people have a normal fasting number but high readings after meals, so this test can catch problems the fasting test misses.

It also matters because:

  • Big rises after meals, day after day, add to your average sugar and your HbA1c.
  • For people with diabetes, it helps show which meals and portions suit your body.

What moves your postprandial blood sugar

What is on your plate matters most.

Pairing rice or roti with dal, paneer, curd or eggs and a big katori of sabzi slows the rise, while a plate that is mostly rice, maida or sweets pushes it up fast.

Habits that help:

  • Eat vegetables and protein first.
  • Keep portions moderate.
  • Take a ten to fifteen minute walk after meals.

Sugary chai and juices with meals add up quickly. If you take diabetes medicine, ask your doctor how food changes fit with it.
