Summary
Type 1 diabetes – Diabetes means your blood glucose, or blood sugar, levels are too high. With type 1 diabetes, your pancreas does not make insulin. Insulin is a hormone that helps glucose get into your cells to give them energy. Without insulin, too much glucose stays in your blood. Over time, high blood glucose can lead to serious problems with your heart, eyes, kidneys, nerves, and gums and teeth. Type 1 diabetes happens most often in children and young adults but can appear at any age. Symptoms may include, being very thirsty, urinating often, feeling very hungry or tired, losing weight without trying, having sores that heal slowly, having dry, itchy skin, losing the feeling in your feet or having tingling in your feet, and having blurry eyesight. A blood test can show if you have diabetes. If you do, you will need to take insulin for the rest of your life.

Diagnostic Tests

Organized Autoimmunity
(Alternative Autoimmune Disease Classification: FIEM, MIEM or BIEM, or FEM, MEM or BEM)
sex predominance (is an autoimmune disease primarily found in genetic Females, Males, or equally in Both?)
Under Investigation
Inherited and acquired gene variations that cause increased susceptibility
Human Leukocyte Antigen (HLA) Associations
“Numerous reports evaluating genetic factors in the development of T1D confirm that HLA-DQ2 and HLA-DQ8 haplotypes strongly predispose to the disease.” (Niegowska et. al, 2016)
Other Gene Variations (mutations)
Variations (mutations) in the protein tyrosine phosphatase non-receptor type 22 (PTPN22) gene (National Institutes of Health, 2022)
Variation (mutations) in islet cell autoantigen 1 (ICA1) (National Institutes of Health, 2022) in insulin-dependent diabetes
Variations (mutations) in islet cell auto antigen 69 (ICA69) (National Institutes of Health, 2022)
Gene Triggering Environmental Exposures
Infections
Mycobacterium avium subspecies paratuberculosis (Niegowska et. al, 2016)
COVID-19 (Chang et. al, 2023, found a significantly higher risk of Type 1 diabetes following COVID-19 infection in a study of 3,814,479 participants)
