    Endometriosis is traditionally conceptualized as a pelvic lesion–centered disease; however, mounting evidence indicates it is a chronic, systemic, and multifactorial inflammatory disorder. This review examines the molecular dialog between ectopic endometrial tissue, the immune system, and peripheral organs, highlighting mechanisms that underlie disease chronicity, symptom variability, and therapeutic resistance. Ectopic endometrium exhibits distinct transcriptomic and epigenetic signatures, disrupted hormonal signaling, and a pro-inflammatory microenvironment characterized by inflammatory mediators, prostaglandins, and matrix metalloproteinases. Immune-endometrial crosstalk fosters immune evasion through altered cytokine profiles, extracellular vesicles, immune checkpoint molecules, and immunomodulatory microRNAs, enabling lesion persistence. Beyond the pelvis, systemic low-grade inflammation, circulating cytokines, and microRNAs reflect a molecular spillover that contributes to chronic pain, fatigue, hypothalamic–pituitary–adrenal axis dysregulation, and emerging gut–endometrium interactions. Furthermore, circulating biomarkers—including microRNAs, lncRNAs, extracellular vesicles, and proteomic signatures—offer potential for early diagnosis, patient stratification, and monitoring of therapeutic responses. Conventional hormonal therapies demonstrate limited efficacy, whereas novel molecular targets and delivery systems, including angiogenesis inhibitors, immune modulators, epigenetic regulators, and nanotherapeutics, show promise for precision intervention. A systems medicine framework, integrating multi-omics analyses and network-based approaches, supports reconceptualizing endometriosis as a systemic inflammatory condition with gynecologic manifestations. This perspective emphasizes the need for interdisciplinary collaboration to advance diagnostics, therapeutics, and individualized patient care, ultimately moving beyond a lesion-centered paradigm toward a molecularly informed, holistic understanding of endometriosis.

    Cardiometabolic diseases—including type 2 diabetes, cardiovascular disease, and metabolic dysfunction–associated steatotic liver disease—are increasingly driven by near-continuous after-meal exposure to glucose and lipid surges that traditional fasting tests often miss. This review prioritizes human studies from 2020 to 2025 and uses earlier work only as foundational anchors; non-English reports were excluded and preclinical findings are cited solely for mechanistic context. Evidence converges on six processes that amplify risk within hours after eating: impaired insulin signaling, delayed clearance of dietary lipids, mitochondrial and oxidative stress, loss of endothelial nitric oxide, inflammasome-mediated inflammation, and microbiome–hormone interactions. Dynamic, after-meal markers and simple composites such as the triglyceride–glucose index outperform fasting measures for identifying risk and guiding care. Practical strategies to shorten the “damage window” include Mediterranean-style meals with low glycemic index swaps and unsaturated fats, earlier distribution of daily energy and early time-restricted eating, a small pre-meal protein portion, and brief post-meal walking. Fast-acting medicines—glucagon-like peptide 1 and glucose-dependent insulinotropic polypeptide receptor agonists, rapid-acting insulin analogues, sodium–glucose cotransporter 2 inhibitors taken before meals, and proprotein convertase subtilisin/kexin type 9 inhibitors—further blunt peaks, while continuous glucose monitoring with algorithmic feedback enables timing-aware, person-specific adjustments. A tiered workflow—screen, stratify, and personalize—reframes prevention and treatment around after-meal physiology, with particular relevance to settings where resources are limited.
