Understanding Your Blood Sugar Numbers 🩸

Blood sugar numbers can feel confusing or scary without clear explanations. If you had gestational diabetes during pregnancy, you may hear terms like CGM, fasting glucose, or HbA1c during postpartum care.

Here is a simple guide to what these numbers mean and how they can help you understand your health.

What a Continuous Glucose Monitor (CGM) Does 📊

A continuous glucose monitor, called a CGM, is a small sensor worn on the arm or stomach. It checks glucose levels throughout the day and night.

A CGM can show how blood sugar changes after:

· Eating

· Sleeping

· Exercise

· Stress

The numbers from a CGM are slightly delayed compared to a finger-prick blood test, but they are very helpful for spotting patterns over time.

What a Finger-Prick Test Does 💉

A finger-prick glucose test measures blood sugar directly from a drop of blood.

It gives a quick reading for that exact moment. It does not show patterns over time, but it is very accurate for checking blood sugar right away.

Important Blood Sugar Numbers 📋

Fasting Blood Sugar

This is checked after not eating for at least 8 hours.

General ranges are:

· Below 100 mg/dL: normal

· 100–125 mg/dL: prediabetes

· 126 mg/dL or higher: possible Type 2 diabetes

Blood Sugar After Meals

This is usually checked 1–2 hours after eating.

For many women after gestational diabetes:

· Below 140 mg/dL after 1 hour is often considered a healthy range

· Below 120 mg/dL after 2 hours is also considered healthy

Higher numbers are not a failure. They can help show which foods or meals raise blood sugar more strongly.

HbA1c

HbA1c is a blood test that shows average blood sugar over the past 3 months.

General ranges are:

· Below 5.7%: normal

· 5.7%–6.4%: prediabetes

· 6.5% or higher: possible Type 2 diabetes

This test looks at long-term patterns, not just one good or bad day.

What Helps Improve Blood Sugar 💛

Small habits can make a big difference over time.

Helpful habits include:

· Taking a short walk after meals

· Eating protein and fiber along with carbohydrates

· Strength training or exercise

· Getting more sleep when possible

· Managing stress

· Eating meals at regular times

When to Talk to Your Doctor 🩺

One high number is usually not an emergency.

But if you notice patterns like:

· Fasting numbers often above 100

· Blood sugar often staying high after meals

…it may be a good idea to talk with your healthcare provider.

You can also ask about repeat blood work if it has been several months since your postpartum diabetes testing.

A Final Reminder 🌱

Your blood sugar numbers are information — not a judgment about you.

They can help guide healthy choices and support your long-term health. One number does not define your body, your effort, or your worth.
