Blood Sugar News and Research

RSS

Blood sugar concentration, or glucose level, refers to the amount of glucose present in the blood of a human or animal. Normally, in mammals the blood glucose level is maintained at a reference range between about 3.6 and 5.8 mM (mmol/l). It is tightly regulated as a part of metabolic homeostasis.

Why vitamin B6 could raise the risk of hypoglycemia for people with diabetes

A large-scale Mendelian randomization study found no genetic evidence that vitamins A, C, or D reduce the risk of major diabetic complications. However, higher genetically predicted vitamin B6 levels were strongly associated with increased risk of diabetic hypoglycemia, warranting caution with supplementation.

UCLA researchers discover new way to prevent immunotherapy-induced type 1 diabetes

A team of researchers at the UCLA Health Jonsson Comprehensive Cancer Center has identified a potential new strategy to prevent, and even reverse, immune checkpoint inhibitor–induced type 1 diabetes, a rare but life-threatening side effect of cancer immunotherapy, using an existing class of autoimmune drugs.

Tirzepatide tops the charts for blood sugar and weight loss in type 2 diabetes

A large network meta-analysis ranked eight GLP-1 receptor agonists for glycemic, weight, and safety outcomes in adults with type 2 diabetes. Tirzepatide demonstrated the greatest efficacy for glucose control and weight loss, while liraglutide offered the lowest hypoglycemia risk.

Study elucidates relationship between Type 2 diabetes and salivary enzyme gene

A new Cornell University study brings additional clarity to the relationship between Type 2 diabetes and genes that express a salivary enzyme that breaks down starch.

Short walks after meals deliver big benefits for blood glucose

A randomized crossover trial in healthy young adults found that a 10-minute walk immediately after glucose intake significantly blunted post-meal blood glucose spikes. Both short and longer walks improved overall glycemic control, but only the immediate walk reduced peak glucose levels.

Coffee’s hidden compounds could help fight type 2 diabetes

A comprehensive review of nearly 150 studies reveals that coffee polyphenols may help regulate blood sugar and reduce inflammation linked to type 2 diabetes. However, most evidence comes from preclinical research, and robust clinical trials are needed to confirm benefits.

Just 150 minutes of exercise a week could reverse prediabetes

Engaging in more than 150 minutes of physical activity per week quadrupled the odds of reversing prediabetes to normal glucose levels in Colombian adults. Higher BMI and HbA1c remained strong barriers to reversal, highlighting the power of lifestyle interventions.

Tirzepatide rewires appetite and slashes calorie intake in new obesity trial

A 6-week randomized trial found that tirzepatide significantly reduced energy intake, appetite, and cravings in adults with overweight or obesity, outperforming liraglutide and placebo. Brain imaging revealed that tirzepatide also lowered neural responses to high-fat, high-sugar food cues, offering mechanistic insight into its potent weight-loss effects.

Lower post-meal blood sugar linked to reduced mortality risk

It is well known that preventing the onset of diabetes reduces the risk of death, and that managing blood glucose levels is key to preventing diabetes.

Plant-based diets may help prevent erectile dysfunction

A narrative review in The Journal of Nutrition suggests that whole-food plant diets may help prevent or improve erectile dysfunction (ED) by supporting vascular health and reducing risk factors such as LDL cholesterol and inflammation. However, most evidence is observational, and more clinical trials are needed.

Is aspartame safe for blood sugar? Study answers the big question

A major systematic review and meta-analysis found that aspartame has little to no effect on blood glucose, insulin, or appetite-regulating hormones in humans. Evidence certainty is very low, with no significant long-term metabolic impact identified.

Stress-activated gene damages insulin-producing cells in type 2 diabetes

Stress does no one - not even your insulin-producing cells - any good.

Diabetes drug semaglutide shows promise in reducing dementia risk

Researchers at the Case Western Reserve School of Medicine have found that semaglutide, a popular diabetes and weight-loss drug, may lower the risk of dementia in people with type 2 diabetes (T2D).

Experimental drug promotes weight loss by heating fat instead of suppressing appetite

An article published in the journal Nature Metabolism presents an experimental drug that stimulates adipose tissue cells to produce heat through a process known as thermogenesis, thereby promoting weight loss.

Clinical trial finds new benefits of semaglutide for adults with type 1 diabetes

A new clinical trial found that taking a popular diabetes and weight-loss drug once weekly significantly improves blood sugar and leads to substantial weight loss in adults with Type 1 diabetes who use automated insulin delivery systems.

Pregnancy complications linked to higher long-term stroke risk in women

Women who experience complications during pregnancy face a higher risk of stroke in the following decades according to research published in the European Heart Journal today (Tuesday).

New oral drug shows promise for type 2 diabetes and obesity without side effects

Lower blood sugar and increased fat burning – without negatively affecting appetite or muscle mass. These are some of the most promising effects of a new potential drug treatment for people with type 2 diabetes and obesity, according to a new study published in the journal Cell by researchers from Karolinska Institutet and Stockholm University.
