International Women’s Day, March 8, 2026
For decades, women’s health has been framed through the lens of hormones. But the emerging science of metabolism suggests that insulin resistance, inflammation and lifestyle factors may be the underlying drivers behind many of the conditions affecting women today.
A worrying trend for women’s health
Around the world, women face increasing rates of chronic health conditions. Infertility, polycystic ovary syndrome (PCOS), depression, autoimmune diseases, metabolic syndrome and abnormal uterine bleeding are becoming more common. At the same time, many women report fatigue, weight gain, digestive problems, mood swings and brain fog—symptoms that often begin years before menopause.
However, the medical debate around women’s health continues to center heavily hormones.
When symptoms do occur, women are often told that the cause lies in fluctuations in estrogen, progesterone, or menopause itself. Hormone replacement therapy, oral contraceptives and antidepressants are usually prescribed. Although these treatments may relieve symptoms for some patients, they do not always address the underlying causes of the disease.
Increasingly, clinicians are beginning to ask a deeper question:
What if many of the health problems affecting women today are metabolic before they are hormonal?
Hormones do not work in isolation
Hormones are often discussed as if they function independently. In fact, hormonal systems are deeply intertwined with metabolism.
Insulin, one of the body’s most powerful metabolic hormones, plays a particularly important role. When insulin levels remain chronically high—a condition often caused by frequent intake of refined carbohydrates and highly processed foods—the body’s tissues may become less responsive to insulin signals. This condition is known as insulin resistance.
Insulin resistance is now widely recognized as a central driver of many chronic diseases, including type 2 diabetes, cardiovascular disease, and fatty liver disease. But it also affects the reproductive system.
Elevated insulin can stimulate ovarian androgen production, disrupt ovulation, and alter the hormonal balance that regulates menstrual cycles. This is one reason why insulin resistance is closely associated with polycystic ovary syndrome (PCOS)one of the most common endocrine disorders in women.
Rather than seeing reproductive symptoms purely as hormonal disturbances, many clinicians now recognize that metabolic dysfunction may be upstream of hormonal imbalance.
When the uterus reflects metabolic health
This metabolic perspective is also gaining ground in gynecology.
In a recent Nutrition Network interview, gynecologist Dr. Andrea Salcedo described the matrix as one “final instrument” which may reflect systemic metabolic health. In her work with patients presenting with abnormal uterine bleeding, she has highlighted how insulin resistance can affect endometrial function and hormone signaling.
If there is metabolic dysfunction, the uterus may respond with irregular or heavy bleeding patterns. Treating the symptoms alone – without addressing the underlying metabolic environment – can leave the root cause unresolved.
This perspective encourages clinicians to look beyond the reproductive system itself and consider broader metabolic drivers, including nutrition, insulin dynamics, and inflammatory signaling.
The metabolic roots of many modern conditions
Insulin resistance is also closely related to chronic inflammationwhich plays a role in numerous diseases that disproportionately affect women.
Autoimmune disorders, for example, occur much more often in women than in men. Conditions such as rheumatoid arthritis, lupus, and thyroid disease often occur alongside metabolic disorders and systemic inflammation.
Likewise, the connection between metabolism and mental health is gaining more and more attention. Emerging research in the field metabolic psychiatry suggests that metabolic dysfunction may affect brain function through multiple mechanisms, including inflammation, mitochondrial dysfunction, and reduced energy metabolism in the brain.
In lectures presented at the Nutrition Network’s training programs, clinicians exploring ketogenic and metabolic therapies highlighted how nutritional strategies that stabilize blood glucose and insulin levels can affect mood, cognition, and neurological health.
While research is ongoing, these ideas reinforce a growing awareness:
The brain, reproductive system and immune system depend on metabolic health.
Nutrition, metabolism and modern lifestyle
If metabolic dysfunction is becoming more common, the obvious question is why.
In recent decades, the global food environment has changed dramatically. Highly processed foods—often rich in refined carbohydrates, industrial seed oils, and added sugars—have become a dominant part of many diets. These foods are designed for convenience and palatability, but can lead to frequent insulin spikes and excessive calorie intake.
At the same time, modern lifestyles often include reduced physical activity, chronic stress, sleep disturbances, and environmental exposures that may further contribute to metabolic dysregulation.
As part of Nutrition Network’s menopause education, clinicians such as Dr. Hassina Kajee have emphasized that early signs of insulin resistance often appear long before the formal diagnosis of metabolic disease. Subtle signs may include weight gain around the belly, fatigue after meals, sugar cravings, skin changes or irregular menstrual cycles.
Recognizing these early signs allows clinicians to intervene earlier — often with lifestyle strategies that directly address metabolic health.
Nutrition as a therapeutic tool
An approach that is receiving increasing attention in metabolic medicine is therapeutic carbohydrate restriction.
By reducing dietary carbohydrate intake, some people experience improved insulin sensitivity, more stable blood glucose levels, and reduced inflammation. This nutritional strategy has been extensively studied in the management of type 2 diabetes and obesity, but clinicians are increasingly exploring its potential role in other conditions associated with metabolic dysfunction.
Nutrition Network lectures by clinicians such as Dr. Robert Cywes, Dr. Hassina Kajeeand others have pointed out how carbohydrate intake affects insulin signaling, appetite regulation, and energy metabolism.
Importantly, nutritional interventions should always be individualized. What works for one patient may not work for another, and medical supervision is essential when implementing significant dietary changes, especially for people with existing medical conditions or medications.
However, the idea is gaining momentum: Nutrition can act as a powerful therapeutic tool, not just a lifestyle recommendation.
Beyond symptom management
For many women, healthcare interactions can be fragmented. Symptoms can be treated individually – antidepressants for mood symptoms, hormonal contraceptives for menstrual disorders, proton pump inhibitors for reflux, or anti-inflammatory drugs for joint pain.
While these treatments may provide relief, they often target the symptoms rather than addressing the systemic factors that may be linking them.
A metabolic lens encourages clinicians to step back and see the bigger picture. Could insulin resistance, inflammation, sleep disturbance, or dietary patterns affect multiple systems simultaneously?
By asking these broader questions, clinicians can discover opportunities to intervene earlier and more holistically.
A new conversation about women’s health
International Women’s Day provides an opportunity to reflect not only on social progress, but also on how we approach women’s health.
For too long, many chronic conditions affecting women have been narrowly framed through hormonal explanations. While hormones undoubtedly play a critical role in female physiology, they are deeply intertwined with metabolic processes that affect the entire body.
Understanding this connection opens up new possibilities for prevention and treatment.
It encourages clinicians to consider nutrition, metabolic health, sleep, movement and stress as central pillars of care. It invites researchers to explore how metabolic therapies can affect conditions that have traditionally been treated with symptom-focused approaches.
Most importantly, it empowers women to ask deeper questions about their health.
Because when we look beyond hormones alone, we begin to see a more complete picture of what drives health — and what can help restore it.
