Type 1 Diabetes
Your immune system mistakenly killed the only cells in your body that make insulin
By the Editors 1-min read
Many people confuse type 1 and type 2 diabetes, assuming both come from 'eating too much sugar.' This is a fundamental misunderstanding.
Type 1 diabetes is the immune system mistakenly attacking and destroying the pancreatic β cells responsible for secreting insulin — not reducing them, wiping them out completely.
It's not a lifestyle disease. It's not from eating the wrong things. It's an autoimmune war — the immune system misidentified its own cells as enemies, then eliminated them entirely.
Patients are often diagnosed in childhood or adolescence — but adult-onset type 1 (LADA, Latent Autoimmune Diabetes of Adults) is increasingly being recognized.
KEY TAKEAWAYS
01
Type 1 diabetes is an autoimmune disease, not a lifestyle disease — the immune system mistakenly attacks and destroys pancreatic β cells, with no direct relationship to dietary habits.
02
At diagnosis, β cells have typically already sustained seventy to ninety percent loss. Autoantibodies (anti-GAD65, etc.) can be detected years before symptoms appear — the most important prodromal biomarkers.
03
Genetics (HLA genes) determines the susceptibility floor; environment (viral infection, gut microbiome) pulls the trigger. Identical twin concordance is only fifty percent, proving environmental factors are crucial.
04
Teplizumab (FDA approved 2022) can delay high-risk individuals' disease onset by approximately two years — the first time type 1 diabetes has had a prodromal-phase intervention.
05
LADA (Latent Autoimmune Diabetes of Adults) accounts for five to ten percent of adult diabetics and is often misdiagnosed as type 2. Correct identification requires autoantibody testing.
