    "description": "Type 2 diabetes almost never appears on lists of things people fear. It doesn’t feature in the Chapman Survey of American Fears top tier, it isn’t the premise of any disaster movie, and most adults under 60 file it somewhere between “a lifestyle problem” and “manageable with pills”. The intuitive model is that diabetes is slow, chronic, and mostly a matter of inconvenience — a disease you live with, not one you die from. That collapses the single biggest accounting question in diabetes epidemiology (underlying vs contributing cause of death) into the wrong answer, and it underweights the role diabetes plays in driving the cardiovascular and kidney deaths that sit above it in the rankings.\n",

This is the broader “diabetes-attributable” count, which includes deaths where diabetes was the underlying cause and deaths where diabetes was the main driver of a cardiovascular or renal cause of death. The narrower WHO “underlying cause” count is much smaller — ~1.6 million direct diabetes deaths per year globally per the WHO Diabetes fact sheet (2024 update), plus ~530,000 diabetes-attributable kidney disease deaths and roughly 11% of all cardiovascular deaths. Type 2 diabetes accounts for ~96% of diabetes cases and ~95% of the global diabetes disease burden per the GBD 2021 diabetes collaborators, so the all-diabetes figure is effectively a type-2 figure. Across a global adult population of ~5.5 billion (age 18+), 6.7 million deaths/year is ~1.22 per 1,000 adults/year. Compounded naively over 60 adult years: 1 - (1 - 1.22e-3)^60 ≈ 0.070. Adjusted modestly upward to 0.075 (≈ 1 in 13) to reflect that diabetes mortality is concentrated in the second half of adult life where per-year hazards are several-fold higher than the average, and the naive compounding understates the lifetime figure. Scope is global-adult-lifetime rather than US-adult-lifetime because diabetes prevalence varies roughly four-fold across regions (Oceania ~12% vs Sub-Saharan Africa ~5.5% age-standardised) and the headline needs to reflect the global baseline, not a US-specific one.\n",

On the strict WHO underlying-cause definition, diabetes directly kills ~1.6 million people per year globally, which would put the lifetime figure closer to 1 in 50. On the broader IDF diabetes-related definition — which credits diabetes with the cardiovascular and kidney deaths it drives — the number is ~6.7 million per year and the lifetime figure is closer to 1 in 13. Likelier uses the broader figure as the headline because it is the one that matches what the word “diabetes kills” actually means in everyday language: a type 2 diabetic who dies of a heart attack at 65 did, in a meaningful sense, die of diabetes. The uncertainty band brackets both methodologies. Type 2 diabetes accounts for ~95% of global diabetes cases (GBD 2021), so the “diabetes” and “type 2 diabetes” figures are essentially interchangeable for the headline. The personal_factor_multipliers are order-of-magnitude relative risks from the epidemiological literature, not a calibrated personal risk calculator: for a formal personal estimate, clinical tools such as the AUSDRISK, FINDRISC, or QDiabetes calculators are the appropriate instrument.\n",
