Type 1 Diabetes

Type 1 diabetes, formerly called juvenile diabetes or insulin-dependent diabetes, is usually first diagnosed in children, teenagers, or young adults. In this form of diabetes, the beta cells of the pancreas no longer make insulin because the body’s immune system has attacked and destroyed them. Treatment for type 1 diabetes includes taking insulin shots or using an insulin pump, making wise food choices, exercising regularly, controlling blood pressure and cholesterol, and taking aspirin daily—for some.

What is Type 1 Diabetes?

Type 1 diabetes mellitus describes a condition where the body cannot produce insulin which leads to a very high level of blood sugar and associated complications. The condition, which usually develops in childhood or adolescence, affects millions of people worldwide.

Very low carbohydrate diets show potential benefits in children with type 1 diabetes

Very low carbohydrate (VLC) diets may be associated with health benefits in children with type 1 diabetes (T1D) and were not associated with acute diabetes complications, new research being presented at the annual meeting of the European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) has found.

European study demonstrates feasibility of population-wide type 1 diabetes screening

New research presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) reports on pilot screening programs for type 1 diabetes from 8 different countries, and the authors – a consortium including Dr Peter Achenbach and Professor Anette-Gabriele Ziegler from the Institute of Diabetes Research, Helmholtz Munich, Munich, Germany – say that screening should be rolled out across Europe, ideally with three testing window: 2-4 years, 6-8 years and 10-15 years.

Type 1 diabetes incidence rose by 11% after rotavirus vaccine rollout in Norway

New research to be presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) and published in Diabetologia (the journal of EASD) shows that incidence (the new case rate) of type 1 diabetes (T1D) in children aged 0.5-5 years in Norway was 11% higher following the rapid roll out and uptake of the rotavirus vaccine in September 2014.

GLP-1 receptor agonist exposure shows no link to major adverse pregnancy outcomes

New research to be presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) and published in The Lancet Obstetrics, Gynaecology & Women's Health shows that, following a review and meta-analysis of available studies, use of glucagon-like peptide-1 receptor agonists (GLP-1 RA) drugs for diabetes and weight management in women living with diabetes is not associated with adverse pregnancy outcomes in most cases.

First EU Screening Week urges citizens to know their numbers

At a dedicated press conference at the EASD Annual Meeting in Milan, organized by the European Diabetes Forum (EUDF), three leading European cardiometabolic scientific associations - the European Society of Cardiology (ESC), the European Association for the Study of Diabetes (EASD) and the European Association for the Study of Obesity (EASO) - joined European Commissioner for Health and Animal Welfare Olivér Várhelyi to welcome the launch of the first-ever EU Screening Week.

A child's gut microbiome may offer early clues to type 1 diabetes risk

Researchers tracking 887 children at high genetic risk of type 1 diabetes identified three distinct patterns of gut microbiome maturation during early childhood. One pattern was associated with substantially higher risk of islet autoantibody seroconversion or type 1 diabetes, while host genetic background altered the risk associated with another pattern.

CGM study finds sexual activity to be safe for people with type 1 diabetes

New research to be presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) shows, with the use of continuous glucose monitoring (CGM) devices, sexual intercourse is safe for people living with type 1 diabetes.

Type 1 diabetes runners can safely complete marathons with careful glucose management

New research to be presented at the Annual Meeting of the European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28th – Oct 2nd) shows, with the use of continuous glucose monitoring (CGM) devices people with type 1 diabetes can complete a marathon safely and achieve finishing times similar to runners without diabetes.

Stricter glucose control may affect quality of life in people living with diabetes

New research to be presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) shows that, in people living with diabetes (type 1 or 2) using data from continuous glucose monitoring (CGM) devices paired with daily quality-of-life ratings, days with more widely fluctuating glucose readings (while still within safe limits) are followed by days with a better quality life compared to days with more stricter control– suggesting the burden of that stricter control could be preventing those individuals with stricter control from enjoying various activities.

COVID-19 linked to lower subsequent risk of type 1 diabetes

New research to be presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) shows that people who have had COVID-19 have a lower, rather than higher, risk of subsequent development of type 1 diabetes (T1D).

People with diabetes may have another reason to protect their cardiovascular health

Better cardiovascular health, measured using Life’s Essential 8, was associated with a lower risk of mild cognitive impairment among people with diabetes after accounting for genetic susceptibility. Associations with dementia varied by genetic risk, while higher LE8 scores were also linked to greater gray matter volume and lower white matter hyperintensity volume.
