Dysbiosis News and Research

RSS

Dysbiosis is a condition caused by an imbalance in the bacterial community (microbiome) of the human gut. Dysbiosis disrupts the ecoystsem of the gut, resulting in symptoms such as diarrhea, constipation, bloating, and indigestion, among others.

Study finds link between Pg-induced periapical disease and systemic metabolic dysfunction

New study examines the oral pathogen Porphyromonas gingivalis (Pg) and suggests its influence may extend beyond dental tissues.

Using a prebiotic after traumatic brain injury may help reduce impulsive behavior

Using a prebiotic to influence bacterial activity in the gut after a traumatic brain injury may help reduce impulsive behavior, one of the common symptoms to follow a moderate blow to the head, a new study in rats suggests.

Study clarifies why most colic isn’t caused by cow’s milk allergy

Cow’s milk allergy rarely causes infant colic on its own, and most excessively crying infants do not have underlying allergy. A short elimination–and–rechallenge trial may help confirm CMA only when colic coexists with other allergic features.

How walnuts combat inflammation and oxidative stress in the body

This review in Food Science & Nutrition synthesizes evidence showing that walnuts (Juglans regia L.) exert potent antioxidant, anti-inflammatory, apoptosis-regulatory, and immunomodulatory effects through bioactive compounds influencing mitochondrial, cytokine, and redox pathways.

Heated tobacco and cigarettes cause the same gut and vascular damage, study finds

Italian researchers found that both heated tobacco products (HTPs) and conventional cigarettes trigger oxidative stress, endotoxemia, and gut barrier disruption in adults and children. The findings challenge the perception that HTPs are a safer alternative to smoking.

Exploring the gut-brain-immune axis in neurodegeneration

Neurodegenerative diseases (NDs), such as Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and multiple sclerosis (MS), represent a growing global health burden, particularly in aging populations.

Scientists uncover the gut’s hidden hydrogen engine and how it falters in Crohn’s disease

Study reveals that group B [FeFe]-hydrogenase is the primary enzyme driving fermentative hydrogen production in the healthy human gut, mainly through Bacteroides species. These genes are significantly depleted in Crohn’s disease, indicating a metabolic shift and altered hydrogen cycling dominated by respiratory bacteria

People with multiple sclerosis found to have dysbiotic oral microbiome

With ads everywhere for pro- or pre-biotic foods and supplements, most people are familiar with the gut microbiome-the trillions of bacteria, fungi, and viruses that colonize our digestive tract-and the idea that keeping our gut microbiome healthy improves our overall health.

Night shift work may raise risk of irritable bowel syndrome

The study indicates that night shift work increases irritable bowel syndrome risk, particularly among those with obesity, due to circadian rhythm disturbances.

Study links gut dysbiosis with severe steatosis in MASLD

A new study in eGastroenterology links gut dysbiosis with severe steatosis in metabolic dysfunction–associated steatotic liver disease (MASLD).

How shifting antibodies fuel aging and the new therapies aiming to slow it

This review uncovers how aging reshapes immunoglobulins, particularly IgG, IgM, and IgA, driving inflammation, cellular senescence, and tissue degeneration. By dissecting B-cell dysfunction, glycosylation changes, and Fc receptor pathways, it reveals immunoglobulins as both biomarkers and potential therapeutic targets in aging.

Western diet fuels IBD by derailing the microbiome - can precision nutrition turn the tide?

This review examines how Western dietary patterns, high in ultra-processed foods, salt, and unhealthy fats, disrupt gut microbiota, impair immune regulation, and contribute to the global rise of inflammatory bowel disease (IBD). It highlights systems biology and nutritional epidemiology as essential tools to develop personalised dietary strategies and shift IBD care from treatment to prevention.
