Study reveals the hidden toll of sudden cardiac death in type 1 and type 2 diabetes

A Danish nationwide study found that people with type 1 and type 2 diabetes have markedly higher rates of sudden cardiac death than the general population, especially at younger ages. At age 30, people with diabetes lose many years of life, with several of those years specifically attributable to sudden cardiac death.

Higher PFAS levels reduce blood sugar improvements after teen bariatric surgery

A new USC study shows teens with higher blood levels of per- and polyfluoroalkyl substances (PFAS) measured before bariatric surgery had smaller improvements in blood sugar over five years, including fasting glucose and hemoglobin A1c (HbA1c), which measures average blood sugar levels over the past 60-90 days.

Sudden cardiac death risk is sharply elevated in people with diabetes

The risk of sudden cardiac death is higher both for people with type 1 and type 2 diabetes, according to a large study published in the European Heart Journal today (Thursday). The increase in risk is especially noticeable among younger adults.

Diabetes drugs linked to slower frailty progression in older adults

A new study shows that older adults with type 2 diabetes who start treatment with sodium–glucose cotransporter-2 (SGLT-2) inhibitors-such as empagliflozin (Jardiance) and dapagliflozin (Farxiga)-or glucagon-like peptide-1 (GLP-1) receptor agonists-such as semaglutide (Ozempic) and liraglutide (Victoza)-experience slower progression of frailty over one year compared with those starting other diabetes medications.

WHO releases first guideline on the use of GLP-1 therapies for treating obesity

To address the growing global health challenge of obesity, which affects more than 1 billion people, the World Health Organization (WHO) has released its first guideline on the use of Glucagon-Like Peptide-1 (GLP-1) therapies for treating obesity as a chronic, relapsing disease.

Maternal exposure to fatty food aromas predisposes offspring to obesity

A research team at the Max Planck Institute for Metabolism Research has found that the smell of fatty foods during pregnancy increases the risk of overweight and obesity in children.

Why green tea delivers the strongest health benefits

This review examines tea's health effects, highlighting green tea's benefits for heart health and cognition, and warns about risks in processed tea products.

Brain recordings reveal why food cravings return despite tirzepatide

Researchers investigate the effects of tirzepatide on food preoccupation by influencing the brain’s mesolimbic circuitry.

Stopping GLP-1 drugs before pregnancy leads to more weight gain

Researchers determine the risk of pregnancy weight gain in patients who were prescribed GLP-1 RAs prior to conception.

Semaglutide helps older adults lose weight without immediate bone loss

Semaglutide shows potential for weight loss in older adults without harming bone density, but longer studies are essential to assess its effects on bone health.

How the gut microbiome links obesity to colorectal cancer

The gut microbiome serves as both a biomarker and therapeutic target in diseases like obesity, metabolic syndrome, and colorectal cancer.

Drinking three to four cups of coffee a day may slow cellular aging

New findings reveal that 3-4 cups of coffee daily may enhance telomere length, potentially slowing cellular aging in individuals with severe mental disorders.

Texture-based analysis of OCT images reveals early retinal changes in diabetes

Diabetic retinopathy (DR) is a leading cause of blindness among working-age adults, affecting more than 130 million people worldwide.

Higher stent complication risks found in patients with diabetes

Patients with diabetes have an increased risk of complications after stent implantation, according to a study from Karolinska Institutet in Sweden published in Diabetes Care.

Researchers uncover key mechanism blocking nerve regeneration in diabetes

Nerve damage is one of the most common and burdensome complications of diabetes. Millions of patients worldwide suffer from pain, numbness, and restricted movement, largely because damaged nerve fibres do not regenerate sufficiently.

Metformin fails to improve insulin resistance in type 1 diabetes

Metformin treatment in type 1 diabetes lowers insulin dosage but does not improve insulin resistance, highlighting its complex role in diabetes management.

Obesity-related metabolic stress may affect brain health far earlier than expected

For decades, scientists have known that what harms the body often harms the brain. Conditions such as obesity, high blood pressure and insulin resistance strain the body's vascular and metabolic systems.

Daily walking patterns help flag early Parkinson’s signs in large UK study

Accelerometer data from nearly 95,000 adults show that higher daily step counts predict lower short-term Parkinson’s disease risk. But as follow-up extends, the association fades, indicating that reduced steps are more likely an early marker than a cause.

Genetic signals reveal why erectile dysfunction develops and who is most at risk

This multi-ancestry genomic study identifies key genetic loci underlying erectile dysfunction and shows that ED risk is shaped by both cardiometabolic and substance use–related genetic pathways. Using EHR-linked data, the researchers uncover SIM1-related mechanisms, modest PRS performance, and bidirectional genetic links with obesity, diabetes, and addiction traits.
