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.

Phone reminders stop nighttime snacking, but not for long

An after dinner or bedtime snack can be hard to resist, but could a gentle nudge from a smartphone app help people with type two diabetes to quit the common habit?

New statement highlights urgent need to improve veterans' heart health

Fewer than 5% of U.S. military veterans may achieve optimal cardiovascular health based on the American Heart Association's Life's Essential 8™ metrics, highlighting an urgent opportunity to improve prevention and help veterans live longer, healthier lives, according to a new scientific statement published today in the Association's flagship journal, Circulation.

Cleaner bedroom air linked to improved blood sugar control

Using portable filters to reduce exposure to air pollution during sleep may stabilize the large spikes in blood sugar experienced by people with prediabetes, a condition in which sugar (glucose) levels are higher than normal, a new study shows.

A three-drug diabetes pill outperformed dual therapy

Clinical trial results indicate that a fixed-dose combination of dapagliflozin, glimepiride, and metformin offers superior glycemic control in diabetes therapy.

A low-calorie diet and exercise helped 54% of younger adults achieve diabetes remission

In a randomized clinical trial involving 96 adults with early-onset type 2 diabetes and obesity, a 24-week program combining a low-energy diet with supervised exercise achieved diabetes remission in 54% of participants, compared with 4% receiving usual care. The intervention also reduced body fat, largely preserved muscle mass, and improved strength and body-mass-adjusted fitness, although the additional benefits attributable specifically to exercise remain uncertain.

New metabolic score may help predict healthy aging and disease risk

Studies conducted in various countries indicate that approximately 60% of people over the age of 65 currently live with two or more chronic conditions simultaneously.

Unraveling the mystery behind lower cancer risks in type 1 diabetes patients

New research in The Journal of Immunology uncovers how high blood sugar (hyperglycemia) and type 1 diabetes (T1D) may protect against certain cancers like melanoma, breast and colon cancer. T1D has been associated with a decreased risk of certain cancers, but the exact reasons why have remained a mystery. New data from studies in mice, now shows that it could be due to changes in immune cells, called T cells, caused by hyperglycemia.

Michigan Medicine study reveals how diabetes drug reduces stroke risk

For millions living with type 2 diabetes, heart disease remains one of the greatest threats to their health.

Novel peptide from red alga shows potential for blood glucose control

It is a dietary staple found in sushi, rice wraps, and ramen toppings. Commonly known as nori in Japan and gim in Korea, red seaweed is especially popular across Asia.

New report urges unified lifecycle approach to women's heart health

A new approach to women's heart health may offer them a lifetime of opportunities. A trio of scientific papers, published today in the journal Circulation, spells out how fluctuating hormones, mental health and well-being, the heart and the brain are linked and how those connections need to be a routine part of care from a young age.

New guidance expands reproductive care for people with cystic fibrosis

For much of the history of cystic fibrosis (CF) care, reproductive health was not a major part of the conversation. Fertility challenges were the norm for men and women with this genetic disorder, and many grew up assuming biological parenthood was not possible.

Electronic implant lowers blood glucose and reduces weight in mice

Type 2 diabetes is becoming increasingly common worldwide. Unlike type 1 diabetes, it is often linked to obesity, a sedentary lifestyle and excess energy intake over many years.

A study of 802 teens raises questions about school breakfast and blood sugar

A study of 802 U.S. adolescents found that school breakfast participation at least once weekly was associated with a 30% higher prevalence of prediabetes-range glucose markers, while school lunch participation showed no significant association. Higher intakes of vitamins E and B6 and fruit consumption among adolescents with obesity were associated with lower prediabetes prevalence, but none of the reported associations remained statistically significant after correction for multiple comparisons.

Blocking specific proteins protects beta cells om excessive cellular stress

Researchers at Weill Cornell Medicine have identified a molecular pathway that contributes to the death of insulin-producing beta cells in the pancreas.

Could eating whey protein before meals help reduce blood sugar spikes?

A narrative review of 57 randomized trials found that milk and dairy products have inconsistent effects on long-term blood sugar control in adults with type 2 diabetes or prediabetes. Whey protein consumed before meals more consistently reduced short-term blood sugar spikes, but further research is needed to establish whether these benefits persist over time.

Miro1 protein linked to insulin resistance in type 2 diabetes

A protein called Miro1 found at elevated levels in the skeletal muscle of people with Type 2 diabetes may contribute to insulin resistance, potentially making it a target for future treatments that help the body regulate blood sugar, according to a study published today in Nature Communications.

Researchers followed glucose monitor users for three years and found a possible kidney benefit

A study of more than 25,000 analytical group assignments involving high-risk adults with type 2 diabetes found that sustained real-time continuous glucose monitoring (rtCGM) was associated with substantial improvements in blood sugar control over three years. Continued use was also linked to lower levels of a marker of kidney damage after three years, although researchers found no evidence that the technology preserved kidney filtration function.
