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.

Vaginal microbiome fights back against stubborn BV infections

Are sweeteners really making our children’s diets healthier?

Higher consumption of low-calorie sweetened (LCS) products among UK children was not consistently linked to reduced free sugar intake, and may reflect less healthy overall dietary patterns. Over 11 years, improvements in dietary quality were slowest among those consuming the most LCS products.

Missing gut bacteria in US babies triples allergy and eczema risk

US infants lacking Bifidobacterium in their gut microbiome face significant changes in microbial composition, metabolic function, and immune-related health risks. This large, nationally representative study links early-life Bifidobacterium deficits to a three-fold increase in eczema, allergy, or asthma by age two.

Study reveals mechanisms behind antibiotic-related immune disruptions in infants

In 2017, scientists at Cincinnati Children's revealed that using antibiotics to protect newborns from dangerous infections often comes with a long-term consequence-a permanently underdeveloped immune system that can make children prone to poor outcomes from future lung infections.

ADHD linked to higher risk of irritable bowel syndrome, global study reveals

A global meta-analysis found that people with ADHD are significantly more likely to have irritable bowel syndrome (IBS), while the overall risk for other intestinal disorders is not increased. The findings highlight the importance of gut-brain interactions in ADHD and call for further research on microbiome-based therapies.

Understanding cow’s milk allergy in breastfed infants

Cow’s milk allergy (CMA) affects up to 2.2% of infants, with a complex interplay of immunological mechanisms, allergen transfer via breast milk, and variable responses to maternal elimination diets. Current evidence challenges the routine use of maternal dietary restrictions, highlighting the need for precise diagnosis and further research.
