Dr Rui Lopes , Clinical Advisor at OMED Health , tells us about the connections between gut microbiomes and hormones , particularly within women , and how breath analysis technology is helping people make sense of the relationship in noninvasive methods .

However , did you know that the gut microbiome also influences your reproductive health ? This happens through changes in hormone regulation , immune function , nutrient metabolism and a variety of other pathways . Certain bacteria in the gut , particularly a group known as the ‘ estrobolome ’, helps regulate levels of fundamental hormones , such as oestrogen , progesterone and follicle-stimulating hormone

( FSH ), which are vital for menstrual cycle regularity and symptoms , follicle development , ovulation and overall reproductive health .

The complex interplay of all these hormones during different stages of the menstrual cycle is a delicate process . This means that an imbalance in the gut microbiome , known as dysbiosis , can have far reaching effects . Poor gut health has been associated with several reproductive conditions , such as polycystic ovary syndrome ( PCOS ), endometriosis and severe premenstrual syndrome ( PMS ). Additionally , hormone fluctuations throughout the menstrual cycle can also affect the gut . For instance , high oestrogen levels can slow down digestion , which explains why many women experience bloating , constipation and nausea in days leading up to menstruation . Progesterone , on the other hand , can have the opposite effect and speed up digestion , leading to symptoms like diarrhoea during certain phases of the cycle .

Women are 1.5 times more likely to experience IBS than men and reproductive hormone shifts are thought to be a contributing factor . Given the close relationship between hormones and gut bacteria , improving gut health may not only help with digestive issues but also support regular menstrual cycles and reduce related symptoms .

Innovations in breath analysis technology are offering new ways to test and monitor gut issues that avoid the discomfort of stool tests or more invasive procedures . At-home devices like the OMED Health Breath Analyser and App aim to help sufferers learn more about what triggers their digestive discomfort . Linked to a clinician network , users can collect breath samples via the device to measure the levels of hydrogen and methane in the breath . These gases are produced by gut bacteria and can give sufferers real insight into the gut , especially when captured alongside key symptoms and dietary factors via the app . With this data , clinicians can advise on the most appropriate treatment should it be needed or provide other guidance to help individuals make informed decisions about their gut health . �
