Chronic Stress and Hormone Disruption

Hormones have a widespread effect on an individual’s mental, physical, and emotional health. In today’s environment, with many patients experiencing anxiety over the COVID-19 pandemic, paying attention to the body’s hormones – and how they fluctuate – has become increasingly important. When they are dysregulated, hormones can cause profound imbalances throughout the body. Studies show that sex hormones and their metabolites may even influence brain areas that regulate mood, behavior, and cognitive abilities.1

Interestingly, research has found that many lifestyle factors can disrupt hormone balance, including nutrition,2-4 exposure to air pollution,5 and chronic stress.6 However, the converse is also true. Evidence continues to grow demonstrating that many lifestyle factors can be altered and improved to reverse hormonal dysregulation and bring the body back into equilibrium. Joel Evans, MD, a longtime IFM educator, describes the impact of chronic stress on hormonal balance in the following video.

Chronic stress alters hormone production, transport, and processing. At the Hormone Advanced Practice Module, the complex interplay between sex hormones, the thyroid, the adrenals, the pituitary, and lifestyle is explored in much greater depth.

As Dr. Evans describes, the adrenal hormones have a powerful effect on all other hormones. Stress can both predispose patients to and precipitate hormonal imbalances.6,7 Stress may also increase symptoms for patients with existing hormone imbalances.8-10 This outsized influence of adrenal hormones is the reason that, when treating hormone imbalances, there is a Functional Medicine tenet that says to “start with the adrenals.” In Functional Medicine, evaluation of stress and stress management strategies offers a low-harm, high-benefit intervention that can assist with downstream thyroid and sex hormone production, transport, and processing. The steroidogenic pathways are modulated by many factors, of which stress is just one example.

One lifestyle factor, physical activity, has many beneficial effects, including decreased levels of stress;11,12 it may also boost levels of muscle-maintaining hormones that decline with age.13,14 For patients who are unable to perform vigorous exercise, regular walking may improve hormone levels and potentially improve strength and quality of life.15 Research has also shown that lower levels of stress biomarkers are associated with stress-reducing techniques like meditation16,17 and even massage.18 A 2005 review of studies found that massage therapy not only reduced cortisol levels by an average of 31% but also increased levels of the mood-boosting hormone serotonin by 28% and levels of dopamine by 31%, on average.18

At IFM’s Hormone Advanced Practice Module (APM), expert educators like Dr. Evans provide the foundational knowledge needed to understand and influence the steroidogenic pathways, central in the formation of all steroid hormones. The course presents novel assessment strategies and highlights the many points of leverage for restoring patients to hormonal balance before resorting to hormone replacement therapy.
