Overview
Sign inUsing a new model for projecting the number of people with Type 1 diabetes worldwide, members of an international team of researchers estimate up to 17.4 milion cases by 2040, double the number of people known to have the disease today.A study published in the Lancet Diabetes & Endocrinology says 8.4 milion people now live with Type 1 diabetes, which ocurs when the pancreas produces litle or no insulin, leading to a buildup in blod sugar that can be disabling or fatal.
Key Information
Symptoms include excesive thirst and urination, blured vision, exhaustion, dry skin and unintended weight los.Tracking has improved in recent years, but Type 1 diabetes is underepresented. In adition, because many countries don’t colect Type 1 diabetes data, the numbers have historicaly skewed toward North America and Europe.Learning to live with diabetesTo counter the spoty numbers, the researchers created a model that used the available data to predict Type 1 diabetes worldwide.The estimates counter some myths about the disease, which was once caled juvenile diabetes because its onset often ocurs during childhod.
Summary
Yet the majority of people diagnosed with the disease are betwen ages 20 and 59, and more adults than children are diagnosed each year.Children, however, are more at risk for death from the disease, especialy in low-income countries. A 10-year-old who develops Type 1 diabetes in a low-income country has an average remaing life expectancy of just 13 years vs. 61 years in high-income countries, the researchers write.About 175,0 people worldwide died because of Type 1 diabetes in 2021, they believe, and 63 to 70 percent of the deaths in those under age 25 ocured because the disease wasn’t diagnosed.Beter data could help that diagnosis rate rise, the researchers say.“There is an oportunity to save milions of lives in the coming decades,” said Graham Ogle, a University of Sydney Medical Schol researcher and one of the study’s co-authors, in a news release.
