Beyond Probiotics: Everything You Need to Know About Women’s Gut Health

The gut harmonises vital processes like digestion, immunity, mood, metabolism, sleep and skin health, influencing overall well-being. Nurturing gut health refines this conductor's baton, optimising every system for a flourishing body.

In this article, we present the knowledge to empower women about their gut health as we explore the human body’s complex symphony of functions centred around the gut - its master conductor. Additionally, we delve into the significant role of sex hormones in shaping gut health and its impact on various conditions and diseases.

The Gut: An Overlooked Key to Well-being

The gut is a vital component of overall well-being. It not only breaks down food into nutrients but it also houses a majority of our immune cells, acting as a crucial defender of our immune system. Within the gut, the enteric nervous system (ENS), often referred to as the "second brain," independently regulates various gastrointestinal processes that impact the entire body. The gut microbiota, the gastrointestinal epithelial barrier and their interplay are the two main determinants of gut health.

Understanding Gender Disparities in Women’s Gut Health

Gut health varies between men and women due to differences in gut bacteria, hormone processing, immune responses and susceptibility to digestive disorders. Scientists call this interplay the "microgenderome." Sex hormones like oestrogen and testosterone shape gut bacteria, impacting the immune system and disease vulnerability. Understanding these connections can lead to personalised approaches for improving women’s gut and overall health based on gender differences. 

The Journey of Gut Health Throughout a Woman's Life

From puberty to menopause, a woman's gut health embarks on a transformative journey driven by hormonal fluxes. Hormonal fluctuations during the menstrual cycle can impact gut health, while menopause ushers in its own set of challenges with hormonal changes influencing the gut microbiome, immune function, emotional processing and chronic diseases risk.

The Menstrual Cycle & Gut Health

Fluctuations in oestrogen and progesterone intricately impact gut function. They can alter gut motility, leading to changes in bowel habits, while also influencing gut permeability, potentially causing bloating and discomfort. Hormones also impact the composition of gut bacteria, crucial for immune function, inflammation regulation, and overall gut health. These fluctuations during the menstrual cycle extend beyond the gut, affecting mood, irritability, fatigue, and food cravings. The gut-brain axis further shapes these effects through intricate communication.

Pregnancy & Gut Health 

Pregnancy triggers notable changes to a woman's body, including gut health. Hormonal fluctuations, immune adaptations, and shifts in dietary patterns contribute to these changes. Increased progesterone levels affect gut motility, causing constipation and bloating. Gastrointestinal muscle tone can also be influenced, leading to acid reflux and heartburn. The immune system undergoes modifications to support the developing foetus, impacting gut health and susceptibility to gastrointestinal conditions. Additionally, dietary habits and nutrient needs are altered during pregnancy, with cravings and aversions affecting food choices. These dietary changes can impact gut microbiota composition, affecting the health of both mother and foetus.

Postpartum Recovery & Gut Health 

Postpartum gut health is influenced by various factors, including hormonal changes, physical stress, dietary adjustments, and childbirth aftermath. These can impact gut bacteria composition, leading to an imbalance in the microbiome. Digestive issues like bloating, gas, and irregular bowel movements may arise. Constipation can occur due to hormonal changes, reduced activity, pain medication, and dietary shifts, contributing to concerns like haemorrhoids. Hormonal changes affect gut motility and digestion, potentially causing changes in bowel habits such as diarrhoea or sluggishness. 

The Perimenopause & Gut Health

Perimenopause, the phase before menopause, brings hormonal changes that affect various aspects of a woman's health, including gut health. Fluctuating oestrogen and progesterone levels during this phase influence the gut microbiome, gut motility, and digestion. Oestrogen’s decline can lead to signs of an unhealthy gut, like bloating and discomfort while also impacting the balance of gut bacteria. Perimenopause is linked to an increased risk of gastrointestinal disorders like irritable bowel syndrome (IBS) and gastroesophageal reflux disease (GERD), causing digestive discomfort and symptoms.

Post Menopause & Gut Health 

Post menopause follows the end of menstrual periods and a significant decrease in hormone production, especially oestrogen, which can impact gut health. Oestrogen maintains the gastrointestinal tract and affects gut bacteria composition. Lower oestrogen levels may lead to changes in gut motility, digestion, and bacterial balance, raising the risk of constipation, bloating, and discomfort. Hormonal fluctuations and natural ageing contribute to these symptoms, while the decline in oestrogen can influence the gut-brain axis, potentially impacting mood and emotional well-being. These changes increase the risk of various chronic diseases, including cardiovascular disease, osteoporosis, urinary tract infections, diabetes and arthritis.

Female-Specific Medications & Gut Health 

Female-specific medications like oral contraceptives and hormone replacement therapy (HRT) impact gut health. These medications contain hormones that affect the gut microbiota and digestive processes in women. 

• Oral contraceptives contain synthetic hormones that mimic oestrogen and progesterone, influencing gut motility and bowel habits. They can also alter the gut microbiome affecting the balance of beneficial bacteria. 
• Hormone replacement therapy (HRT) is prescribed to alleviate menopause symptoms and it also influences gut motility and gut microbiota composition. Oestrogen supplementation may improve gut transit time and reduce constipation risk.

Exercise & Gut Health 

Intense physical training impacts the gastrointestinal system, particularly for women athletes, who face unique challenges due to increased energy demands, dietary choices, and physiological changes from training. Biological differences between men and women influence exercise performance, recovery, and injury susceptibility due to hormonal factors. Vigorous exercise can affect gut motility, causing exercise-induced gastrointestinal distress, bloating, or diarrhoea. It can also lead to "leaky gut," contributing to systemic inflammation.

Diet, Weight & Gut Health 

Female hormones impact both gut health and weight at various stages of a woman's life.

• During puberty, hormonal changes lead to increased body fat deposition, especially in the hips, thighs, and breasts. Hormones like oestrogen and progesterone affect appetite regulation and fat storage. 
• The menstrual cycle brings hormonal shifts influencing food cravings, appetite, and water retention, leading to weight  fluctuations and changes in gut function during different phases. 
• Pregnancy involves significant hormonal changes and natural weight gain, which can impact gut health and increase the risk of complications if excessive. 
• Menopause, the cessation of menstrual periods, is associated with hormonal changes leading to weight gain, particularly in the abdominal region, due to declining oestrogen levels, changing fat distribution and a decreased rate of metabolism.

Female-Specific Diseases & Gut Health  

Women’s health shows certain distinctions from men’s, with females generally living longer and being less susceptible to infectious diseases but more susceptible to immune system mediated diseases. Around 80% of individuals with autoimmune diseases are women. Gut health plays a significant role in various conditions that exhibit sex-specific disparities:

• Irritable Bowel Syndrome (IBS): Differences in gut microbiota composition between males and females with IBS, with 19% of sufferers being females and 9% males, suggest sex-specific microbial influences on the condition's development and severity.
• Inflammatory Bowel Disease (IBD): Disparities in gut microbiota composition between the sexes, with 0.44% of sufferers being females and 0.35% being males, imply gender-related factors contributing to variations in disease susceptibility and progression.
• Autoimmune Diseases: Conditions like rheumatoid arthritis, multiple sclerosis, and systemic lupus erythematosus, have been associated with gut microbiota alterations, potentially modulating immune responses and disease development, which are more prevalent in females. 
• Urinary Tract Infections (UTIs): Recurrent UTIs in females, with 23% being women and 7% being men, have been linked to changes in the gut microbiota, influencing susceptibility to these infections.
• Polycystic Ovary Syndrome (PCOS): PCOS affects the reproductive system but research suggests impacts on gut health through alterations in gut microbiota composition, potentially linking to insulin resistance, a common feature of the disorder.
• Osteoporosis: Females, with a prevalence of 51% compared to 28% males, face an increased risk of osteoporosis due to the decline in oestrogen levels after menopause, leading to accelerated bone loss.
• Cardiovascular Disease (CVD): Post-menopause increases the risk of CVD, with oestrogen playing a crucial role in maintaining healthy blood vessels and cholesterol levels. Females face an increased risk of death caused by CVD, with a prevalence of 55% compared to 43% males.
• Metabolic Syndrome (MS): Post-menopause increases the risk of developing MS in women and leading onto the risk of type 2 diabetes, heart disease, and stroke. The overall MS prevalence in females is 39% compared to 31% males.
