KNOW YOUR STORY. BUILD YOUR RESERVE.

Blood Sugar
& Your Heart

Your blood sugar is part of a bigger story.

Pregnancy. Menopause. Family history. Blood pressure. Cholesterol. Blood sugar.

These can look like separate pieces of your health. But sometimes the useful information is in how those pieces fit together.

This tool helps you gather the parts of your history that may matter, put your numbers in one place, and leave with questions you can take to your clinician.

This is not a diagnosis or a diabetes risk calculator. It is a tool to help you know your story and have a better conversation about what may deserve attention next.

PAST · ALL QUESTIONS ARE OPTIONAL

What has happened before?

You do not need to know every medical term. Choose what you remember, or leave a question blank.

My pregnancy history

Gestational diabetes

Diabetes first diagnosed during pregnancy.

High blood sugar during pregnancy

Include this even if you do not remember a diagnosis. It may overlap with gestational diabetes.

Preeclampsia or high blood pressure during pregnancy

Use the name you remember, or choose “I’m not sure.”

A baby born early (preterm delivery)

Birth before 37 weeks of pregnancy.

A baby who was very small or did not grow as expected

Your medical record may use the terms fetal growth restriction, FGR, or IUGR.

PCOS

Have you been told you have PCOS?

PCOS means polycystic ovary syndrome, a condition involving hormones and the ovaries.

My family history

Type 2 diabetes in my family

If you know, note which relative in the space below.

Heart disease at a young age in my family

Note the relative, what happened and their age, if known. You do not need to decide what counts as “early.”

My previous blood-sugar history

A previous high glucose or A1c result

Glucose means blood sugar. A1c is a blood test that gives an estimate of your average blood sugar over about three months.

A previous diagnosis of prediabetes

Only record a diagnosis you have been given.

A previous diagnosis of diabetes

If you know the type, add it in your notes.

For example: when it happened, weeks pregnant, a twin pregnancy, or the words you remember.

You can add a relative’s diagnosis and age, a diabetes type, or a detail you want to check.

THE MIDLIFE CONNECTION

Can menopause affect my blood sugar?

During perimenopause—the years leading up to menopause—hormone changes may affect how your body handles blood sugar. Insulin is the hormone that helps move sugar from your blood into your cells. Sleep, activity, changes in muscle and body fat, age, family history, and some medicines can matter too.

If your blood sugar changes during these years, it is worth bringing up with your clinician rather than assuming it is “just menopause.” It does not mean that every woman going through menopause will develop diabetes.

What did the 2026 study find?

Researchers looked at health information from 9,248 U.S. women. Women in perimenopause were more likely to fall into the study’s less-healthy blood-sugar category than women who had not yet reached perimenopause, even after researchers took age into account.

What does that mean for you?

The study found a connection. It did not prove that menopause caused the blood-sugar difference, and it cannot predict what will happen to one individual woman.

The study also does not mean that blood sugar rose by 83% or that a woman has an 83% chance of developing diabetes.

What about continuous glucose monitoring?

A continuous glucose monitor (CGM) is a wearable sensor that shows how glucose changes throughout the day and night. These monitors are an important clinical tool for many people with diabetes and may be used in other circumstances when a clinician determines they are appropriate.

But more data is not automatically more useful.

If you use a glucose monitor, the goal of HEART RESERVE is to help you place that information in context—with your medical history, pregnancy history, medications, blood pressure, cholesterol, menopause status and other factors your clinician considers.

Questions to ask before focusing on glucose data

  • Why are we measuring this?
  • What pattern are we looking for?
  • What would actually change my care?
  • How long do I need to monitor?
  • Who should help me interpret the results?

This resource does not suggest that every woman needs a glucose monitor. A single glucose spike does not diagnose a condition. Ask your clinician whether monitoring would be useful for you.

Sources & scope

2026 study details for clinicians and interested readers

Nayak and colleagues analyzed U.S. survey data from 9,248 women. Compared with women before perimenopause, those in perimenopause had higher age-adjusted odds of a poor blood-glucose score in the American Heart Association’s Life’s Essential 8 framework: odds ratio 1.83 (95% CI 1.06–3.17).

This was a cross-sectional study: it compared groups, rather than following the same women through menopause. It cannot prove that menopause caused the difference or predict what will happen to an individual woman. Menopause stage was based on reported menstrual history.
