Perimenopause and Blood Sugar: Why You Feel Off, Anxious, or Crave Sugar
How Perimenopause Affects Blood Sugar and Insulin Resistance
During perimenopause, hormonal shifts can increase insulin resistance and make blood sugar more difficult to regulate.
Many women notice shifts in energy, mood, sleep, and weight that feel difficult to explain. One of the underlying drivers is often changes in blood sugar regulation, especially as part of the broader hormonal transition.
If you are newer to this phase, you can read more about what this transition looks like here:
Perimenopause Symptoms and What to Expect
This is not just about diet. It is a combination of hormonal shifts, sleep disruption, and metabolic changes that occur during this transition.
One of the most important changes is an increase in insulin resistance. This tends to happen alongside:
Increased abdominal weight gain
Changes in mood or increased anxiety
Higher baseline stress levels
Symptoms of Blood Sugar Imbalance in Perimenopause
Symptoms of blood sugar imbalance during perimenopause can include fatigue, anxiety, cravings, and brain fog. Blood sugar changes do not just impact long-term health. They can significantly affect how you feel day to day.
When blood sugar is less stable, you may notice:
Midday or afternoon crashes
Strong cravings for sugar or carbohydrates
Feeling shaky, anxious, or irritable
Brain fog or difficulty concentrating
Fatigue that does not improve with rest
If you are also dealing with disrupted sleep, this can further worsen blood sugar regulation. I go deeper into this connection here: Perimenopause Sleep Problems: Why You’re Waking at Night and What You Can Do
Elevated insulin levels can also contribute to:
Water retention
Increased blood pressure
Reduced energy for movement or exercise
Perimenopause, Weight Gain, and Blood Sugar Changes
Weight gain during perimenopause is often linked to changes in blood sugar regulation, insulin resistance, and shifting hormone levels. Blood sugar and hormones are closely connected.
As insulin resistance increases:
The body is more likely to store energy as fat, particularly around the abdomen
Energy levels decrease, which can reduce daily movement
Sleep disruption worsens blood sugar control further
If weight changes have been one of your biggest frustrations, I break this down more here:

At the same time, fluctuations in estrogen and progesterone can
Affect appetite and cravings
Influence how sensitive your body is to insulin
Impact where and how weight is stored
Why You Crave Sugar More During Perimenopause
Sugar cravings during perimenopause are often driven by blood sugar instability, sleep disruption, and hormonal changes. Cravings are often not about willpower! And this is something I encourage my patients to drop from the narrative that plays in their minds.
They are frequently driven by physiology.
Blood sugar instability can lead to rapid drops in energy, which signals the body to seek quick sources of fuel. This often shows up as cravings for:
Sugar
Refined carbohydrates
Comfort foods
For many women, this overlaps with emotional or stress-related eating patterns, especially during times of fatigue or hormonal shifts.
Best Lab Tests for Blood Sugar and Insulin Resistance
Lab testing during perimenopause can help identify early insulin resistance and changes in blood sugar regulation., even before more obvious issues develop.
Helpful markers include:
Fasting glucose
Fasting insulin
Hemoglobin A1C
HOMA-IR (a calculation based on glucose and insulin levels)
If you are looking for a more personalized approach to testing and interpretation, this is something I walk through in detail with patients: Work With a Perimenopause Doctor in the Bay Area
In general:
A HOMA-IR below 1.9 suggests more optimal insulin sensitivity
An A1C above 5.7 may indicate early insulin resistance
How to Support Blood Sugar Balance During Perimenopause
Supporting blood sugar balance during perimenopause requires a root-cause approach that includes nutrition, sleep, stress, and hormone health. It is not just about removing sugar or following a strict diet.
It involves looking at the full picture, including:
Nutrition and meal timing
Sleep quality
Stress and nervous system regulation
Hormone balance
Physical activity and muscle mass

When to Get Help for Blood Sugar Changes in Perimenopause
If you are experiencing symptoms of blood sugar imbalance in perimenopause, early support can help prevent longer-term metabolic issues.
If you are noticing changes in energy, cravings, mood, or weight that feel new or difficult to manage, it may be helpful to look more closely at blood sugar and metabolic health.
These changes are common during perimenopause, but they are not something you have to push through without support!
