How Blood Sugar Imbalances Affect Women’s Hormones

It's Monday morning, you rush out the door, coffee and bagel in your hand. You power through your morning work trying to stay focused. That 11am meeting went long and now you've missed your window for lunch, there's no time to run out and grab lunch. You raid the office kitchen and find some snack bars or maybe make a run to a convenient store for some quick energy. Now it's 3pm and your energy is tanking, a headache is starting to form, and you're worn out. 5pm finally arrives and you jump in the car to head home and arrive feeling exhausted and irritable. You are too tired to make the dinner you planned, so you order in and maybe over indulge just a little too much. "Tomorrow", you think, "tomorrow I'll plan better and get out of this slump".

Does any of that sound like you? Thanks to this modern world we live in, this scenario is far too common. This pattern of eating quick energy-releasing foods isn't doing us any favors and sets us up for major blood sugar dysregulation, energy slumps, mood swings, and can eventually lead to difficulty losing weight no matter how hard you try.

Blood sugar regulation isn't just for those struggling with diabetes, it is for all of us! Stable blood sugar is one the foundations for hormone stability. From insulin to testosterone to estrogen to cortisol, it all improves with stable blood sugar.

Key Players Collaborate

Hormones do not work in isolation, they are constantly communicating with each other to keep your body functioning. Just like great teams collaborate, great hormones work together to support your energy!

Insulin is the main blood sugar hormone. Produced in the pancreas, insulin helps move glucose from the bloodstream into the cell where it can be used to generate energy. When we consume large amounts of sugar or refined carbohydrates (foods like bread, pasta, crackers, chips), glucose levels rise and the pancreas responds by pumping out more insulin. Frequent spikes in blood sugar lead to increased insulin production.

Chronically elevated insulin can contribute to:

• Weight gain

• Increased inflammation

• Greater risk of insulin resistance

Cortisol is our stress hormone. Your adrenal glands release cortisol in response to physical and emotional stress. This is actually a very protective measure because it raises blood sugar to give you quick energy to deal with the stressor. However, this can become problematic if cortisol remains too high for too long and contributes to inflammation.

Chronic stress can:

• Increase glucose production by the liver

• Increase insulin demand

• Promote abdominal fat storage

• Trigger cravings for sugary foods

Estrogen supports insulin sensitivity by helping the cells respond more effectively to insulin, allowing glucose to enter easily. As estrogen declines during perimenopause and menopause, insulin sensitivity can drop and blood sugar can become more difficult to regulate. This can often lead to undesired weight gain as excess glucose and insulin promotes fat storage.

Progesterone has a more nuanced relationship with blood sugar since it does not regulate glucose the way insulin does. However, it does influence insulin sensitivity, appetite, stress response and metabolic rate. Progesterone rises during the luteal phase of the menstrual cycle (after ovulation) and with that, insulin sensitivity can decrease. This desensitization can lead to higher blood levels of insulin and circulating glucose and is often why women notice increased hunger, cravings, or slightly higher blood glucose readings during this phase!

Testosterone is another key hormone that is connected to blood sugar. Testosterone's main metabolic role is to preserve lean muscle. The more lean muscle is on your body, the better your cells can let glucose in and listen to insulin's signals. When testosterone drops, muscle mass decreases and fat mass often increases and this is why we often see high fasting glucose and low testosterone levels.

Signs Your Blood Sugar May Be Unstable

The relationship between your hormones and blood sugar is often overlooked and poorly understood, but your body is super intelligent and sends signals when this relationship is strained - we just need to learn to recognize them!

Here are common symptoms that we often overlook:

• afternoon energy crashes

• fatigue after meals

• difficulty waking up in the morning

• constant hunger

• intense cravings for sweets or carbohydrates

• feeling "hangry" between meals

• irritability

• anxiety

• brain fog or difficulty concentrating

• increased abdominal weight gain

• difficulty losing weight

• increased appetite despite adequate calorie intake

• waking up between 2-4am

• difficulty staying asleep

• night time hunger

Many people assume these symptoms are solely hormone-related, when in reality they are important signals that blood sugar regulation needs attention!
How To Eat to Keep Blood Sugar Stable

Always, always pair your carbohydrates with fat and protein! Never eat them alone unless you want a roller coaster of energy highs and lows. Especially the simple carbs like pasta, bread, crackers, chips, and sugary snacks - these carbohydrates digest quickly and spike blood sugar fast. They provide a quick burst of energy but fizzle out fast. Pairing carbs with fat and protein will help slow the release of glucose into the blood stream and give insulin adequate time to respond without spiking and in turn giving you steady energy.

Bonus points if your carbohydrate is rich in fiber! Soluble fiber breaks down and forms a gel-like substance that helps coat your intestinal lining and contributes to a slow steady absorption of glucose. This helps prevent post meal blood sugar spikes and subsequent drops!

Prioritize protein at every meal:

Examples:

• Eggs

• Greek yogurt

• Fish

• Poultry

• Beef

• Tofu

• Tempeh

Build Balanced Meals:

A balance of protein + fiber + healthy fats is where it's at!

Examples:

• Chicken (protein) + roasted vegetables (fiber-rich carb) + avocado (fiber-rich fat)

• Salmon (protein + fat) + quinoa (fiber-rich carb) + broccoli (fiber-rich carb)

• Greek yogurt (protein + fat)  + berries (fiber-rich carb) + walnuts (fiber-rich fat)

Stop Skipping Meals

Long periods of eating may increase cortisol in some people and lead to overeating later in the day. Blood sugar dips can worsen energy and mood fluctuations - there's a reason you feel hangry before lunch and feel like you need an afternoon nap every day.

Small Changes That Can Make a big Difference

Understanding the why is half the battle, making small impactful changes is the second half. There are so many simple ways to support your blood sugar and improve energy and hormone communication.

Practical Starting Points

• Include 20–30 grams of protein at breakfast

• Add vegetables to lunch and dinner

• Take a 10-minute walk after meals

• Pair carbohydrates with protein or healthy fats

• Prioritize sleep and stress management

Blood sugar balance is not only a metabolic issue—it is a hormone health issue. When blood sugar is consistently supported, individuals often experience improvements in:

• Energy

• Cravings

• Mood

• Weight management

• Sleep quality

• Hormonal symptoms during perimenopause and menopause
