Diabetes mellitus, often known simply as diabetes, is a group of common endocrine diseases characterized by sustained high blood sugar levels. [ 10][ 11] Diabetes is due to either the pancreas not producing enough insulin, or the cells of the body becoming unresponsive to the hormone's effects. [ 12] Classic symptoms include thirst, polyuria ...
392 million (2015) [ 11] Type 2 diabetes ( T2D ), formerly known as adult-onset diabetes, is a form of diabetes mellitus that is characterized by high blood sugar, insulin resistance, and relative lack of insulin. [ 6] Common symptoms include increased thirst, frequent urination, fatigue and unexplained weight loss. [ 3]
Polygenic. Genetic cause and mechanism of type 2 diabetes is largely unknown. However, single nucleotide polymorphism (SNP) is one of many mechanisms that leads to increased risk for type 2 diabetes. To locate genes and loci that are responsible for the risk of type 2 diabetes, genome wide association studies (GWAS) was utilized to compare the ...
Epidemiology of diabetes. Prevalence (per 1,000 inhabitants) of diabetes worldwide in 2000 - world average was 2.8%. Globally, an estimated 537 million adults are living with diabetes, according to 2019 data from the International Diabetes Federation. [ 1] Diabetes was the 9th-leading cause of mortality globally in 2020, attributing to over 2 ...
Polyol pathway. The polyol pathway is a two-step process that converts glucose to fructose. [ 1] In this pathway glucose is reduced to sorbitol, which is subsequently oxidized to fructose. It is also called the sorbitol-aldose reductase pathway . The pathway is implicated in diabetic complications, especially in microvascular damage to the ...
Diabetic ketoacidosis ( DKA) is a potentially life-threatening complication of diabetes mellitus. [ 1] Signs and symptoms may include vomiting, abdominal pain, deep gasping breathing, increased urination, weakness, confusion and occasionally loss of consciousness. [ 1] A person's breath may develop a specific "fruity" smell. [ 1]
Endocrinology. Complications of diabetes are secondary diseases that are a result of elevated blood glucose levels that occur in diabetic patients. These complications can be divided into two types: acute and chronic. Acute complications are complications that develop rapidly and can be exemplified as diabetic ketoacidosis (DKA), hyperglycemic ...
Diabetic retinopathy (also known as diabetic eye disease ), is a medical condition in which damage occurs to the retina due to diabetes. It is a leading cause of blindness in developed countries. Diabetic retinopathy affects up to 80 percent of those who have had both type 1 and type 2 diabetes for 20 years or more.
