"characterized by abnormally high blood glucose concentrations, and generalized body wasting. In type 2 diabetes mellitus the destruction of beta cells is less pronounced than in type 1 diabetes, and is not due to an autoimmune process. Instead there is an accumulation of amyloid in the pancreatic islets, which likely disrupts their anatomy and physiology. The pathogenesis of type 2 diabetes is not well understood but patients exhibit a reduced population of islet beta-cells, reduced secretory function of islet beta-cells that survive, and peripheral tissue insulin resistance. Type 2 diabetes is characterized by high rates of glucagon secretion into the"
"Insulin resistance Insulin resistance (IR) is considered as a pathological condition in which cells fail to respond normally to the hormone insulin. To prevent hyperglycemia and noticeable organ damage over time, the body produces insulin when glucose starts to be released into the bloodstream, primarily from the digestion of carbohydrates in the diet. Under normal conditions of insulin reactivity, this insulin response triggers glucose being taken into body cells, to be used for energy, and inhibits the body from using fat for energy, thereby causing the concentration of glucose in the blood to decrease as a result, staying within the"

The body requires insulin produced by the pancreas, in order to uptake glucose within the cells for the production of energy (ATP) and to perform active processes within the body, such as digestion, muscle contraction and brain stimulation. Over time those susceptible will experience weight gain as well as nutritional gaps as they will be unable to adequately absorb nutrients required by the body. This is a fatal"

"Insulin is a hormone that regulates glucose levels, allowing the body's cells to absorb and use glucose. Without it, glucose cannot enter the cell and therefore cannot be used as fuel for the body's functions. If the pancreas is exposed to persistently high elevations of blood glucose levels, the insulin-producing cells in the pancreas could be damaged, causing a lack of insulin in the body. Insulin resistance occurs when the pancreas tries to produce more and more insulin in response to persistently elevated blood glucose levels. Eventually, the rest of the body becomes resistant to the insulin that the pancreas"
"IDDM11 Insulin-dependent (type I)diabetes mellitus (IDDM) is a genetic heterogenouse autoimmune disorder, which is triggered by genetic predisposition and environmental factors. The prevalence of insulin-dependent (type I) diabetes mellitus (IDDM) among children and young adult from Europe is approximately 0.4%. Insulin-dependent (type I) diabetes mellitus (IDDM) is characterized by acute onset and insulin deficiency. Patients with insulin-dependent (type I) diabetes mellitus (IDDM) are found with gradual loss of the pancreatic islet beta cells and therefore not able to produce insulin. As a result, they usually need exogenous insulin to maintain their life. Genome-wide linkage analysis could be used for identification"
"illness that affects how the body uses food, and is a life-threatening human disease if left untreated. It affects more than 171 million people worldwide. Diabetes mellitus can be subdivided into; type I diabetes, where the body does not produce insulin, the hormone which facilitates the uptake of glucose by cells; and type II diabetes, where the body becomes resistant to insulin, thus inhibiting the extent of glucose usage. In each case, the ineffective use of glucose as a source of energy leads to the subsequent breakdown of fatty acids to compensate. This consumption of fatty acids by ketosis, produces"
"The main activity of activation of the insulin receptor is inducing glucose uptake. For this reason ""insulin insensitivity"", or a decrease in insulin receptor signaling, leads to diabetes mellitus type 2 – the cells are unable to take up glucose, and the result is hyperglycemia (an increase in circulating glucose), and all the sequelae that result from diabetes. Patients with insulin resistance may display acanthosis nigricans. A few patients with homozygous mutations in the ""INSR"" gene have been described, which causes Donohue syndrome or Leprechaunism. This autosomal recessive disorder results in a totally non-functional insulin receptor. These patients have low-set,"

Diabetes mellitus (DM) is a group of metabolic diseases that are characterised by hyperglycaemia and defects in insulin production in the pancreas and/or impaired tolerance to insulin effects. DM is a leading cause of morbidity and mortality. Because the disease may be insidious, the diagnosis often is delayed. Effects of the disease may affect larger blood vessels (e.g., atherosclerosis within the larger arteries of the cardiovascular system) or smaller blood vessels, as"
"2 diabetes. Type 2 diabetes is due to insufficient insulin production from beta cells in the setting of insulin resistance. Insulin resistance, which is the inability of cells to respond adequately to normal levels of insulin, occurs primarily within the muscles, liver, and fat tissue. In the liver, insulin normally suppresses glucose release. However, in the setting of insulin resistance, the liver inappropriately releases glucose into the blood. The proportion of insulin resistance versus beta cell dysfunction differs among individuals, with some having primarily insulin resistance and only a minor defect in insulin secretion and others with slight insulin resistance"

The body destroys 70-80% of beta cells, leaving only 20–30% of functioning cells. This can cause the patient to experience hyperglycemia, which leads to other adverse short-term and long-term conditions. The symptoms of diabetes can potentially be controlled with methods such as regular doses of insulin and sustaining a proper diet. However, these methods can be tedious and cumbersome to continuously perform on a daily basis. Type 2 diabetes mellitus, also known as non insulin dependent diabetes, is caused primarily by genetics"

Research on the two types of HAIR-AN demonstrated that patients with both forms of HAIR-AN had very high levels of insulin and, critically, that it was the high insulin that caused the elevation in androgen. The patient affected by HAIR-AN syndrome has insulin resistance inside their body. Insulin resistance is a condition in which the body produces insulin but does not use it properly. This causes the pancreas to produce more insulin"
"Hyperproinsulinemia Hyperproinsulinemia is a disease where insulin is not sufficiently processed before secretion and immature forms of insulin make up the majority of circulating insulin immunoreactivity in both fasting and glucose-stimulated conditions (insulin immunoreactivity refers to all molecules detectable by an insulin antibody, i.e. insulin, proinsulin, and proinsulin-like material). The term is composed of ""hyper"" - high, ""proinsulin"" - immature insulin molecule, and ""-emia"" - blood condition. Hyperproinsulinemia is more frequent in type 2 diabetes. It has been attributed to either a direct β-cells defect or an indirect effect of cell dysregulation under sustained elevated blood glucose (hyperglycemia). Some alleles"

Other potentially important mechanisms associated with type 2 diabetes and insulin resistance include: increased breakdown of lipids within fat cells, resistance to and lack of incretin, high glucagon levels in the blood, increased retention of salt and water by the kidneys, and inappropriate regulation of metabolism by the central nervous system. However, not all people with insulin resistance develop diabetes, since an impairment of insulin secretion by pancreatic beta cells is also required.

"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"

Type 1 diabetes can develop at any age but is most often diagnosed before adulthood. For people living with type 1 diabetes, insulin injections are critical for survival. An experimental procedure to treat type 1 diabetes is the transplantation of pancreatic islet cells from a donor into the patient's liver so that the cells can produce the deficient insulin.

In one case, it was found (by culturing pancreatic cells) that the receptor produced by the mutant allele is only about 15% as effective as the normal receptor. The beta cells in the pancreas, which make and store insulin and release it on an as-needed basis, are often found to be very large or numerous. In some patients, particularly those who are longer-lived, unusual bone changes are sometimes seen, and there may"

"II diabetes (T2DM) pathogenesis are insulin resistance and impaired insulin secretion. In the earlier stages of disease development, cells throughout the body become resistant to the effects of insulin. Therefore, insulin is unable to cause cells to take up glucose (among other impairments) and glucose builds up in the blood. As a result, insulin secretion is ramped up, to try to compensate for this lack of response. For a while this may work, but eventually, the body's ability to secrete insulin from the pancreatic beta cells gets burnt out. In later stages of T2DM, patient cells are both resistant to"
"Diabetes management The term ""diabetes"" includes several different metabolic disorders that all, if left untreated, result in abnormally high concentration of a sugar called glucose in the blood. Diabetes mellitus type 1 results when the pancreas no longer produces significant amounts of the hormone insulin, usually owing to the autoimmune destruction of the insulin-producing beta cells of the pancreas. Diabetes mellitus type 2, in contrast, is now thought to result from autoimmune attacks on the pancreas and/or insulin resistance. The pancreas of a person with type 2 diabetes may be producing normal or even abnormally large amounts of insulin. Other"

Various disease states make body tissues more resistant to the actions of insulin. Examples include infection (mediated by the cytokine TNFα) and acidosis. Recent research is investigating the roles of adipokines (the cytokines produced by adipose tissue) in insulin resistance. TNF-α has been found in increased amounts in obese patients. Due to its effects on adipocytes it is possible that excessive TNF-α is one of several factors that leads to insulin resistance. TNF-α can inhibit lipogenesis, promote lipolysis, disrupt"
