There are many medical causes of Diabetes. Below is a table of medical conditions that may result in an elevated blood glucose and the diagnosis of Diabetes. The list, which is divided into 4 major categories- Type 1, Type 2, Gestational Diabetes and other- is adapted from the American Diabetes Association.
Etiologic classification of Diabetes Mellitus – based on American Diabetes Association criteria
https://care.diabetesjournals.org/content/44/Supplement_1/S15
- Type 1 Diabetes (ß-cell destruction, usually leading to absolute insulin deficiency)
- Immune mediated
- Idiopathic
- Type 2 Diabetes (may range from predominantly insulin resistance with relative insulin deficiency to a predominantly secretory defect with insulin resistance)
- Gestational Diabetes Mellitus (GDM)
- Other specific types
- Genetic defects of ß-cell function also known as Maturity Onset Diabetes of the Young or MODY
- Chromosome 12, HNF-1∝ (MODY3)
- Chromosome 7, glucokinase (MODY2)
- Chromosome 20, HNF-4 (MODY1)
- Chromosome 13, insulin promoter factor-1 (IPF-1; MODY4)
- Chromosome 17, HNF-1ß (MODY5)
- Chromosome 2, NeuroD1 (MODY6)
