GLP-1 therapy associated with more dizziness and fainting

https://www.news-medical.net/news/20260614/GLP-1-therapy-associated-with-more-dizziness-and-fainting.aspx Northwestern Medicine scientists have identified a safety concern associated with GLP-1 drugs. Using health record data, the research team tracked more than 42,000 adults already taking at least two types of blood pressure medications. After starting GLP-1s, these patients experienced higher rates of dizziness, fainting and other events related to low blood pressure, also known as hypotension.

Eliminating dietary sugar may disrupt gut health and promote inflammation

https://www.news-medical.net/news/20260614/Eliminating-dietary-sugar-may-disrupt-gut-health-and-promote-inflammation.aspx Eliminating sugar from your diet may be more detrimental than previously thought, according to an animal study being presented Saturday at ENDO 2026, the Endocrine Society's annual meeting in Chicago, Ill.

How Gut Fungi and Archaea Influence Human Health

https://www.news-medical.net/health/How-Gut-Fungi-and-Archaea-Influence-Human-Health.aspx The non-bacterial gut microbiome, particularly fungi and archaea, plays an important role in metabolism, immune regulation, and microbial ecosystem stability through complex interactions with bacteria and the host. Emerging research links fungal dysbiosis and methanogenic archaea to obesity, inflammatory disorders, gastrointestinal disease, and potential future microbiome-based therapies. The gut microbiome comprises bacteria, fungi, archaea, viruses, and other microorganisms that influence health and disease. The biological significance of intestinal bacteria is well-established; however, recent advances in sequencing technologies indicate that both the gut mycobiome and archaeome are involved in metabolism, immune regulation, and microbial balance that influence the risk of developing obesity, inflammatory disorders, and diseases of the gastrointestinal tract.1,2,3 Although fungi represent only a small fraction of total gut microbes, they can have disproportionate effects through immune signaling, microbial competition, and interactions with bacteria

How to Stay Motivated to Exercise

https://www.news-medical.net/health/How-to-Stay-Motivated-to-Exercise.aspx Why do some people maintain exercise habits for years while others quit within weeks? Emerging research shows that enjoyment, autonomy, positive emotions, and social support are often more important for long-term adherence than knowing the health benefits alone. Regular physical activity reduces the risk of chronic diseases while improving both physical and psychological health. Despite these established benefits, many individuals struggle to adhere to a regular exercise routine, whereas others are more successful at sustaining long-term exercise habits. Understanding why some people continue exercising while others discontinue is essential for developing effective long-term health interventions. Exercise adherence can be understood not only as compliance with a program, but also as the dynamic alignment between a person's attitudes and exercise behavior.

How Meal Timing Affects Metabolism and Weight Loss

https://www.news-medical.net/health/How-Meal-Timing-Affects-Metabolism-and-Weight-Loss.aspx Meal timing helps regulate hunger, glucose control, lipid metabolism, and energy balance through its alignment with circadian rhythms. Eating earlier and maintaining consistent meal and sleep schedules may support better metabolic health. Meal timing is increasingly recognized as a key determinant of metabolic health, as it influences glucose homeostasis, energy production, and hormonal regulation. Aligning food intake with endogenous circadian rhythms has the potential to improve metabolic outcomes and reduce the risk of obesity, type 2 diabetes, and other cardiometabolic disorders.

Oral GLP-1 drug elecoglipron helps adults lose up to 11.8% body weight

https://www.news-medical.net/news/20260611/Oral-GLP-1-drug-elecoglipron-helps-adults-lose-up-to-11825-body-weight.aspx A once-daily oral small-molecule GLP-1 receptor agonist delivered progressive, dose-dependent weight loss without food or fluid restrictions, supporting larger phase 3 trials for long-term weight management. In a recent study published in The Lancet, a group of researchers evaluated the efficacy, safety, and tolerability of oral non-peptide small-molecule elecoglipron for weight management in adults with obesity or overweight and at least one weight-related health condition without diabetes.
