Genetic variants may help explain who loses more weight and who gets side effects on GLP-1 drugs

A large 23andMe-based GWAS found that common variants in GLP1R and GIPR help explain why some people lose more weight or experience more nausea and vomiting on GLP-1 drugs. The findings suggest genetics may eventually help predict who responds best to semaglutide or tirzepatide and who is more likely to develop side effects.

Can diet influence thyroid disease? A major review points to Mediterranean-style eating

This review found that thyroid health depends on more than iodine alone, with selenium, iron, zinc, vitamins, omega-3s, and overall eating patterns all shaping thyroid function and autoimmunity. It also concluded that Mediterranean-style diets are linked to more favorable thyroid outcomes, while unnecessary restrictive diets offer little benefit without a clear medical indication.

Testosterone level is not always the key to male wellbeing

The connection between testosterone and well-being is weaker than many people think. Although there are clear health connections, a higher testosterone level is not always the key to well-being, according to a thesis at the University of Gothenburg.

How do diet, smoking, alcohol, and stress reshape the female microbiome?

This review examines how modifiable lifestyle and environmental factors shape the female vaginal, gut, oral, and skin microbiomes, with diet, alcohol, smoking, obesity, stress, hygiene, physical activity, and sexual behaviours all linked to site-specific microbial shifts. It argues that understanding these patterns could help guide future female-focused prevention and intervention strategies.

Time-restricted eating improves hormone levels in women with PCOS

Polycystic ovary syndrome, or PCOS, affects as many as 18% of all childbearing-age women. The condition occurs when a woman's body produces too much of a group of hormones called androgens, chiefly testosterone. Menstrual irregularity, obesity and even infertility can result.

Discontinuing beta-blockers after heart attack found to be safe for low-risk patients

Among stable, relatively low-risk patients who had previously suffered a heart attack, discontinuing beta-blockers after at least one year was found to be non-inferior, or comparable, to continuing beta-blockers in terms of death, another heart attack or hospitalization for heart failure, according to a study presented at the American College of Cardiology's Annual Scientific Session.

Systematic review identifies stress-induced biological triggers in oncology

Stress is a constant companion in the oncologist's office. It appears at the time of diagnosis, increases with each stage of treatment, and often does not resolve even after therapy formally ends. It accompanies therapeutic decisions, waiting for test results, fear of recurrence, and changes in daily functioning. Studies show that chronic stress can trigger biological processes that promote disease progression and weaken the body's defenses.
