Glucagon is one of the most important blood sugar hormones, yet most women with PCOS have never had it explained to them.
You may have heard about insulin resistance. You may have been told to reduce sugar, walk after meals, lose weight, eat more protein or check your HbA1c. But insulin is only one side of the blood sugar story.
The other side is glucagon.
If insulin helps bring blood sugar down after food, glucagon helps bring blood sugar up when it drops too low. Together, they act like a metabolic switchboard, helping the body maintain steady energy between meals, during fasting, during exercise and during stress.
For women with PCOS/PMOS, or what many newer conversations call PMOS because of the metabolic component, this matters deeply. Blood sugar instability can show up as cravings, energy crashes, hunger soon after eating, abdominal weight gain, fatigue, mood dips and difficulty managing weight despite effort.
Understanding glucagon does not mean blaming another hormone. It means seeing the full system.
Glucagon is a hormone made by alpha cells in the pancreas. Its main job is to prevent blood sugar from dropping too low.
When blood sugar falls, glucagon tells the liver to release stored glucose into the bloodstream. This helps the brain, muscles and organs continue getting energy when food is not immediately available.
| Hormone | Main Job | When It Rises |
|---|---|---|
| Insulin | Helps lower blood sugar and move glucose into cells | After eating, especially after carbohydrates |
| Glucagon | Helps raise blood sugar by signalling the liver | Between meals, during fasting, exercise or stress |
Insulin and glucagon are not enemies. They are partners. The problem begins when the balance between them becomes disrupted.
PCOS is often discussed as a reproductive condition, but it is also strongly linked with metabolic health. Many women with PCOS have insulin resistance, which means the body needs more insulin to manage blood sugar.
When insulin signalling is not working well, the rest of the blood sugar system can become more unstable too. Glucagon may not switch off as smoothly after meals, the liver may continue releasing glucose when it is not needed, and women may experience more cravings, hunger and energy dips.
This is why a woman with PCOS may say:
“I ate properly, but I am hungry again.”
“My energy crashes after meals.”
“I crave carbs even when I am trying so hard.”
“My body feels unpredictable.”
These symptoms are not always about discipline. Sometimes, they reflect a blood sugar rhythm that needs support.
(SD).
Think of your body like a control room.
| Situation | Insulin Should Do | Glucagon Should Do |
|---|---|---|
| After a balanced meal | Rise gently to move glucose into cells | Reduce because food is available |
| Between meals | Lower gradually | Rise slightly to keep energy stable |
| During stress | May become less effective | May rise to provide emergency glucose |
| In insulin resistance | Often stays higher | May become harder to regulate |
| With poor sleep | Appetite control may worsen | Blood sugar rhythm may become unstable |
This is why the solution is not only “eat less sugar.” The goal is to make the whole switchboard calmer.
The fastest way to create blood sugar instability is to eat meals that are mostly refined carbohydrates without enough protein, fibre or healthy fat.
For women with PCOS, this may lead to a quick glucose rise, a larger insulin response and then a crash that feels like fatigue, hunger or cravings.
A better plate structure looks like this:
| Plate Component | Why It Helps |
|---|---|
| Protein | Supports satiety and steadier glucose response |
| Fibre | Slows digestion and supports gut hormones |
| Healthy fats | Helps meals feel satisfying |
| Slow carbohydrates | Provides energy without a sharp spike |
| Vegetables | Adds volume, minerals and gut support |
Good examples include dal with vegetables and curd, paneer with millet roti and salad, eggs with vegetables, sprouts with curd, chana with cucumber, or tofu with brown rice and greens.
The goal is not restriction. The goal is rhythm.
GLP-1 stands for glucagon-like peptide 1. Despite the name, GLP-1 usually helps reduce post-meal glucagon, supports insulin release when glucose is present, slows stomach emptying and helps the body feel fuller.
This is one reason GLP-1 medicines are being studied and used in metabolic conditions. But for everyday PCOS care, the first step is supporting your own gut hormone response through food and lifestyle.
Fibre is especially important because it feeds gut bacteria and helps regulate post-meal glucose.
Add more:
Dal, chana, rajma and sprouts
Bhindi, beans, carrots, greens and gourds
Chia seeds, flaxseeds and pumpkin seeds
Oats, millets and whole grains
Guava, apple, berries and citrus fruits
Start slowly if you struggle with bloating. Fibre works best when increased gradually with enough water.
Glucagon can rise during stress because the body prepares for action by making more glucose available.
This was useful when stress meant running from danger. It is less useful when stress means deadlines, exams, family pressure, relationship stress, body image distress or constant overthinking.
For women with PCOS, chronic stress can worsen cravings, sleep, cortisol, insulin resistance and emotional eating. That means stress care is not a soft suggestion. It is metabolic care.
Try these realistic stress supports:
Walk for 10 minutes after meals
Sleep and wake at similar times
Avoid skipping meals during busy days
Practise slow breathing before dinner
Reduce late-night scrolling
Build one non-negotiable recovery window daily
Seek therapy if stress feels constant or overwhelming
A calmer nervous system often supports a calmer blood sugar pattern.
Muscle is one of the body’s biggest glucose users. When muscle is active and well maintained, blood sugar management becomes easier.
This is why strength training is so powerful for women with PCOS. It supports insulin sensitivity, body composition, energy, mood and long-term metabolic health.
You do not need extreme workouts. Begin with:
| Beginner Option | How Often |
|---|---|
| Bodyweight squats | 2 to 3 times weekly |
| Resistance bands | 2 to 3 times weekly |
| Pilates or strength yoga | 2 to 3 times weekly |
| Supervised gym training | 2 to 4 times weekly |
| Walking after meals | Most days |
Exercise should help the body feel more responsive, not more punished.

This is not a diagnostic checklist, but it can help you know when to seek guidance.
| What You Notice | What It May Suggest |
|---|---|
| Hunger soon after meals | Meal balance or blood sugar swings |
| Cravings for sugar or carbs | Glucose dips, stress or insulin resistance |
| Energy crash after eating | Post-meal glucose variability |
| Abdominal weight gain | Insulin resistance, stress or PCOS pattern |
| Irregular periods | PCOS, thyroid, prolactin or hormone imbalance |
| Acne or facial hair | Androgen excess may need evaluation |
| Dark neck patches | Possible insulin resistance |
| Fatigue with cravings | Blood sugar and sleep may need review |
If these patterns are frequent, speak to a doctor or women’s health expert.
Glucagon is not usually tested in routine PCOS care. Instead, doctors often look at the wider metabolic picture.
| Test | Why It May Help |
|---|---|
| Fasting glucose | Screens baseline blood sugar |
| Fasting insulin | Helps assess insulin resistance |
| HbA1c | Shows average blood sugar over time |
| Lipid profile | Reviews metabolic risk |
| Liver function tests | Screens fatty liver risk |
| Thyroid profile | Rules out thyroid related weight and cycle issues |
| Testosterone and DHEA-S | Reviews androgen excess |
| Prolactin | Rules out another cause of irregular periods |
| Ultrasound | May support PCOS evaluation when needed |
Women with PCOS deserve a full metabolic review, not just advice to lose weight.

Miror PCOS is designed for women navigating PCOS related concerns such as irregular cycles, cravings, acne, hirsutism, insulin sensitivity and hormonal imbalance.
Since PCOS often involves metabolic strain, blood sugar swings, cravings and hormone disruption, Miror PCOS can be part of a broader daily support routine alongside nutrition, movement, sleep care, stress management and clinical guidance.
It is not a treatment for diabetes, glucagon disorders, infertility or endocrine disease. But it can support the wellness foundation women need while addressing PCOS more consistently and intelligently.
Glucagon is the missing half of the blood sugar conversation for many women with PCOS.
Insulin matters. But insulin does not work alone.
Your hunger, cravings, fatigue and weight changes may be connected to a larger blood sugar switchboard involving insulin, glucagon, GLP-1, cortisol, stress, sleep, gut health and muscle.
At Miror, we believe women should not be blamed for symptoms that have a biological explanation. PCOS is not a failure of discipline. PMOS is not a failure of willpower. It is a hormonal and metabolic condition that deserves proper care.
Your body is not asking for punishment. It is asking for steadier signals.

Glucagon is a hormone made by the pancreas that helps raise blood sugar when it drops too low. It works with insulin to keep blood sugar stable. While insulin helps move glucose from the blood into cells after eating, glucagon tells the liver to release stored glucose when the body needs energy between meals, during fasting, exercise or stress.
Glucagon and blood sugar are closely connected because glucagon helps prevent blood sugar from falling too low. When blood sugar drops, glucagon signals the liver to release glucose into the bloodstream. When blood sugar rises after a meal, insulin should increase and glucagon should reduce. If this balance is disturbed, women may experience hunger, cravings, fatigue or blood sugar swings.
Glucagon matters for women with PCOS or PMOS because PCOS is often linked with insulin resistance and blood sugar instability. When insulin does not work efficiently, the body may struggle to regulate glucose properly. Glucagon may also remain active when it should reduce after meals, contributing to cravings, energy crashes, hunger soon after eating and difficulty managing metabolic health.
Glucagon itself is not the only cause of cravings, but it is part of the blood sugar system that influences hunger and energy. In women with PCOS, cravings may be linked to insulin resistance, glucose dips, poor sleep, stress, irregular meals and gut hormone changes such as GLP-1 response. When the insulin glucagon rhythm is unstable, hunger can feel more urgent and biological rather than simply emotional.
Women can support healthy glucagon and blood sugar balance by eating balanced meals with protein, fibre, healthy fats and slow carbohydrates. Walking after meals, strength training, sleeping well, managing stress, reducing refined sugar and avoiding long gaps between meals can also help. For women with PCOS or PMOS, Miror PCOS can be part of a broader wellness routine alongside nutrition, movement and expert medical guidance.
