Abstract
Endocrine dysfunctions refer to alterations in hormone production, release, or regulation that can significantly impact health. In pregnant women or those planning pregnancy, these conditions may manifest as disorders such as polycystic ovary syndrome, hypothyroidism, endometriosis, gestational diabetes mellitus, and other metabolic issues, which could potentially cause infertility or pregnancy complications. Research and clinical experience indicate that hormones play a crucial role in basic physiology and are essential for overall health and well-being. At the same time, lifestyle-defined as daily habits related to nutrition, exercise, sleep, stress management, and other factors-directly influences microbial composition and hormonal regulation. The human microbiome, a diverse community of microorganisms residing within the human body, plays essential roles in supporting overall health. The increasing prevalence of hormonal disorders, especially in urban populations, has heightened interest in how modern lifestyles-characterised by sedentary habits, chronic stress, imbalanced diets, and inadequate sleep-may contribute to the development or aggravation of these conditions, leading to higher infertility rates or pregnancy complications if untreated. This review investigates the interaction between hormonal dysfunction, the human microbiome, and lifestyle factors, with a focus on their effects on pregnant women and those seeking to conceive. Its purpose is to provide a comprehensive overview of the underlying pathophysiological mechanisms and to examine preventative and therapeutic approaches that could alter these patterns.
