Constipation belongs to conditions commonly reported by postmenopausal women, but the mechanism behind this association is not fully known. The aim of the present study was to determine the relationship between some metabolites of tryptophan (TRP) and the occurrence and severity of abdominal symptoms (Rome IV) in postmenopausal women with functional constipation (FC, n = 40) as compared with age-adjusted postmenopausal women without FC. All women controlled their TRP intake in their daily diet. Urinary levels of TRP and its metabolites, 5-hydroxyindoleacetic acid (5-HIAA), kynurenine (KYN), and 3-indoxyl sulfate (indican, 3-IS), were determined by liquid chromatography/tandem mass spectrometry. Dysbiosis was assessed by a hydrogen–methane breath test. Women with FC consumed less TRP and had a lower urinary level of 5-HIAA, but higher levels of KYN and 3-IS compared with controls. The severity of symptoms showed a negative correlation with the 5-HIAA level, and a positive correlation with the 3-IS level. In conclusion, changes in TRP metabolism may contribute to FC in postmenopausal women, and dysbiosis may underlie this contribution.

Menopause, through attributable estrogen level decline and the corresponding increase in circulating androgens, significantly elevates a woman's risk for cardiometabolic diseases, including metabolic syndrome (MetS), type 2 diabetes, and cardiovascular disease. Metabolic syndrome itself is a cluster of interconnected risk factors, and among them, central obesity is a well-established factor for the development of endometrial cancer (EC), the most common gynecologic malignancy. This research investigates the impact of metabolic syndrome on survival rates among patients with endometrial cancer. The goal is to assess whether having metabolic syndrome or its individual components influences disease-free survival (DFS), overall survival (OS), cancer-specific survival, and recurrence rates. Understanding this link is crucial for determining risk levels and could help tailor treatment approaches for better long-term outcomes in endometrial cancer care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
