Misaligned hormonal rhythmicity: Mechanisms of origin and their clinical significance

Abstract: Rhythmic hormonal secretion is key for sustaining health. While a central pacemaker in the hypothalamus is the main driver of circadian periodicity, many hormones oscillate with different frequencies and amplitudes. These rhythms carry information about healthy physiological functions, while at the same time they must be able to respond to external cues and maintain their robustness against severe perturbations.Since endocrine disruptions can lead to hormonal misalignment and disease, understanding the clinica… Show more

“…Our dMs allow us to shift from a qualitative to a quantitative description of variability. Because they are mathematically defined, dMs constitute an unambiguous method to describe healthy hormonal rhythms and facilitate further analysis through nonstationary statistics and machine learning techniques ( 39 ). In our analysis, it is interesting that we found only a few factors likely to influence healthy hormone concentrations, and none were profound.…”

“…Our dMs may allow stratification of normality across subpopulations (for example, by sex, age, or BMI), and the same approach could also be generalized to quantify hormonal misalignment arising from behavioral and environmental factors (such as sleep, light exposure, meal content and timing, smoking habits, etc.) ( 39 ). The combination of high–time resolution continuous hormone sampling with noninvasive wearable devices and computational analysis techniques has the potential to support clinical diagnosis and disease management according to individual physiotypes ( 40 ).…”

“…The hypothalamus's intrinsic pacemaker functions as the principal regulator of circadian periodicity, whereas several hormones exhibit oscillatory patterns with varying frequencies and amplitudes. The aforementioned rhythms are required to exhibit responsiveness to external stimuli, retain their resilience when confronted with significant disruptions, and convey pertinent data regarding the state of sound physiological operation [20]. Regular hormone release is crucial for sustaining optimal health.…”

“…Combining experimental physiology with mathematical and computational techniques contributes to our understanding of the mechanisms underpinning rhythmic hormonal secretion, how rhythms are decoded by target tissues, and their responses to perturbations [ 1 ]. This allows us to understand how regulatory mechanisms ensure that hormone fluctuations achieve dynamic equilibration, and how disruptions of these mechanisms lead to rhythm misalignment and disease [ 2 , 3 ]. Phenomenologically, these techniques allow more precise descriptions of the endocrine systems over time, and are foundational to the development of digital health tools, as in diagnostic and screening algorithms [ 4 ].…”
