Diabetes mellitus type 1 Diabetes mellitus type 1 Diabetes mellitus type 1, also known as type 1 diabetes, is a form of diabetes mellitus in which very little or no insulin is produced by the pancreas. Before treatment this results in high blood sugar levels in the body. The classic symptoms are frequent urination, increased thirst, increased hunger, and weight loss. Additional symptoms may include blurry vision, feeling tired, and poor wound healing. Symptoms typically develop over a short period of time. The cause of type 1 diabetes is unknown. However, it is believed to involve a combination of genetic and environmental factors. Risk
Genetic causes of diabetes mellitus type 2 genes, and these differences in the nucleotide sequences alter phenotypic traits that exhibit increased susceptibility to the diabetes. GWAS has revealed 65 different loci (where single nucleotide sequences differ from the patient and control group's genomes), and genes associated with type 2 diabetes, including "TCF7L2", "PPARG", "FTO", "KCNJ11","NOTCH2", "WFS1", "IGF2BP2", "SLC30A8", "JAZF1", "HHEX, DGKB, CDKN2A, CDKN2B, KCNQ1, HNF1A, HNF1B MC4R, GIPR, HNF4A, MTNR1B, PARG6, ZBED3, SLC30A8, CDKAL1, GLIS3, GCKR," among others."KCNJ11" (potassium inwardly rectifying channel, subfamily J, member 11), encodes the islet ATP-sensitive potassium channel Kir6.2, and "TCF7L2" (transcription factor 7–like 2) regulates proglucagon gene expression and thus the production
