Several genetic loci have been determined to be associated with insulin insensitivity. This includes variation in loci near the NAT2, GCKR, and IGFI genes associated with insulin resistance. Further research has shown that loci near the genes are linked to insulin resistance.

In normal metabolism, the elevated blood glucose instructs beta β cells in the Islets of Langerhanslocated in the pancreasto release insulin into the blood. The insulin makes insulin-sensitive tissues in the body primarily skeletal muscle cells, adipose tissue, and liver absorb glucose which provides energy as well as lowers blood glucose.

In an insulin-resistant person, normal levels of insulin do not have the same effect in controlling blood glucose levels.

When the body produces insulin under conditions of insulin resistance, the cells are unable to absorb or use it as effectively and it stays in the bloodstream. Certain cell types such as fat and muscle cells require insulin to absorb glucose and when these cells fail to respond adequately to circulating insulin, blood glucose levels rise.

The liver normally helps regulate glucose levels by reducing its secretion of glucose in the presence of insulin. However, in insulin resistance, this normal reduction in the liver's glucose production may not occur, further contributing to elevated blood glucose.

Insulin resistance in fat cells results in reduced uptake of circulating lipids and increased hydrolysis of stored triglycerides.

This leads to elevated free fatty acids in the blood plasma and can further worsen insulin resistance. In states of insulin resistance, beta cells in the pancreas increase their production of insulin.

This causes high blood insulin hyperinsulinemia to compensate for the high blood glucose. During this compensated phase of insulin resistance, beta cell function is upregulated, insulin levels are higher, and blood glucose levels are still maintained.

If compensatory insulin secretion fails, then either fasting impaired fasting glucose or postprandial impaired glucose tolerance glucose concentrations increase. Eventually, type 2 diabetes occurs when glucose levels become higher as the resistance increases and compensatory insulin secretion fails.

Insulin resistance is strongly associated with intestinal-derived apoB production rate in insulin-resistant subjects and type 2 diabetics. With respect to visceral adiposity, a great deal of evidence suggests two strong links with insulin resistance.

In numerous experimental models, these proinflammatory cytokines disrupt normal insulin action in fat and muscle cells and may be a major factor in causing the whole-body insulin resistance observed in patients with visceral adiposity.

Second, visceral adiposity is related to an accumulation of fat in the liver, a condition known as non-alcoholic fatty liver disease NAFLD. The result of NAFLD is an excessive release of free fatty acids into the bloodstream due to increased lipolysisand an increase in hepatic breakdown of glycogen stores into glucose glycogenolysisboth of which have the effect of exacerbating peripheral insulin resistance and increasing the likelihood of Type 2 diabetes mellitus.

The excessive expansion of adipose tissue that tends to occur under sustainedly positive energy balance as in overeating has been postulated by Vidal-Puig to induce lipotoxic and inflammatory effects that may contribute to causing insulin resistance and its accompanying disease states.

Also, insulin resistance often is associated with a hypercoagulable state impaired fibrinolysis and increased inflammatory cytokine levels. From a broader perspective, however, sensitivity tuning including sensitivity reduction is a common practice for an organism to adapt to the changing environment or metabolic conditions.

This can be achieved through raising the response threshold i. Insulin resistance has been proposed to be a reaction to excess nutrition by superoxide dismutase in cell mitochondria that acts as an antioxidant defense mechanism.

This link seems to exist under diverse causes of insulin resistance. It also is based on the finding that insulin resistance may be reversed rapidly by exposing cells to mitochondrial uncouplers, electron transport chain inhibitors, or mitochondrial superoxide dismutase mimetics.

During a glucose tolerance test GTTwhich may be used to diagnose diabetes mellitus, a fasting patient takes a 75 gram oral dose of glucose. Then blood glucose levels are measured over the following two hours. Interpretation is based on WHO guidelines. After two hours a glycemia less than 7.

An oral glucose tolerance test OGTT may be normal or mildly abnormal in simple insulin resistance. Often, there are raised glucose levels in the early measurements, reflecting the loss of a postprandial peak after the meal in insulin production.

Extension of the testing for several more hours may reveal a hypoglycemic "dip," that is a result of an overshoot in insulin production after the failure of the physiologic postprandial insulin response. The gold standard for investigating and quantifying insulin resistance is the "hyperinsulinemic euglycemic clamp," so-called because it measures the amount of glucose necessary to compensate for an increased insulin level without causing hypoglycemia.

The test is rarely performed in clinical care, but is used in medical research, for example, to assess the effects of different medications.

The rate of glucose infusion commonly is referred to in diabetes literature as the GINF value. The procedure takes about two hours. Through a peripheral veininsulin is infused at 10— mU per m 2 per minute. The rate of glucose infusion is determined by checking the blood sugar levels every five to ten minutes.

The rate of glucose infusion during the last thirty minutes of the test determines insulin sensitivity. If high levels 7. Very low levels 4. Levels between 4. This basic technique may be enhanced significantly by the use of glucose tracers.

Glucose may be labeled with either stable or radioactive atoms. Commonly used tracers are 3- 3 H glucose radioactive6,6 2 H-glucose stable and 1- 13 C Glucose stable.

Prior to beginning the hyperinsulinemic period, a 3h tracer infusion enables one to determine the basal rate of glucose production. During the clamp, the plasma tracer concentrations enable the calculation of whole-body insulin-stimulated glucose metabolism, as well as the production of glucose by the body i.

Another measure of insulin resistance is the modified insulin suppression test developed by Gerald Reaven at Stanford University. The test correlates well with the euglycemic clamp, with less operator-dependent error. This test has been used to advance the large body of research relating to the metabolic syndrome.

Patients initially receive 25 μg of octreotide Sandostatin in 5 mL of normal saline over 3 to 5 minutes via intravenous infusion IV as an initial bolus, and then, are infused continuously with an intravenous infusion of somatostatin 0. Blood glucose is checked at zero, 30, 60, 90, and minutes, and thereafter, every 10 minutes for the last half-hour of the test.

These last four values are averaged to determine the steady-state plasma glucose level SSPG. Given the complicated nature of the "clamp" technique and the potential dangers of hypoglycemia in some patientsalternatives have been sought to simplify the measurement of insulin resistance.

The first was the Homeostatic Model Assessment HOMA[52] and more recent methods include the Quantitative insulin sensitivity check index QUICKI [53] and SPINA-GRa measure for insulin sensitivity. Maintaining a healthy body weight and being physically active can help reduce the risk of developing insulin resistance.

The primary treatment for insulin resistance is exercise and weight loss. Metformin is approved for prediabetes and type 2 diabetes and has become one of the more commonly prescribed medications for insulin resistance. The Diabetes Prevention Program DPP showed that exercise and diet were nearly twice as effective as metformin at reducing the risk of progressing to type 2 diabetes.

Furthermore, physical training has also generally been seen to be an effective antagonist of insulin resistance in obese or overweight children and adolescents under the age of

Causes and Risk Factors of Insulin Resistance	If you inject insulin as a treatment for your diabetes and have insulin resistance, it does not mean you are resistant to that specific brand or type of insulin. But you may need to increase the doses or use higher doses to cover the same amount of carbohydrate. To help make the insulin more effective again, your healthcare team might also suggest that you need to start other medications such as Metformin alongside your insulin. Metformin can be prescribed to help reduce insulin resistance whether you have type 1 or type 2 diabetes. A company limited by guarantee registered in England and Wales with no.

Given the complicated nature of the "clamp" technique and the potential dangers of hypoglycemia in some patients , alternatives have been sought to simplify the measurement of insulin resistance. The first was the Homeostatic Model Assessment HOMA , [52] and more recent methods include the Quantitative insulin sensitivity check index QUICKI [53] and SPINA-GR , a measure for insulin sensitivity. Maintaining a healthy body weight and being physically active can help reduce the risk of developing insulin resistance. The primary treatment for insulin resistance is exercise and weight loss. Metformin is approved for prediabetes and type 2 diabetes and has become one of the more commonly prescribed medications for insulin resistance. The Diabetes Prevention Program DPP showed that exercise and diet were nearly twice as effective as metformin at reducing the risk of progressing to type 2 diabetes. Furthermore, physical training has also generally been seen to be an effective antagonist of insulin resistance in obese or overweight children and adolescents under the age of Resistant starch from high-amylose corn, amylomaize , has been shown to reduce insulin resistance in healthy individuals, in individuals with insulin resistance, and in individuals with type 2 diabetes. Some types of polyunsaturated fatty acids omega-3 may moderate the progression of insulin resistance into type 2 diabetes, [62] [63] [64] however, omega-3 fatty acids appear to have limited ability to reverse insulin resistance, and they cease to be efficacious once type 2 diabetes is established. The concept that insulin resistance may be the underlying cause of diabetes mellitus type 2 was first advanced by Professor Wilhelm Falta and published in Vienna in , [66] and confirmed as contributory by Sir Harold Percival Himsworth of the University College Hospital Medical Centre in London in ; [67] however, type 2 diabetes does not occur unless there is concurrent failure of compensatory insulin secretion. Some scholars go as far as to claim that neither insulin resistance, nor obesity really are metabolic disorders per se , but simply adaptive responses to sustained caloric surplus, intended to protect bodily organs from lipotoxicity unsafe levels of lipids in the bloodstream and tissues : "Obesity should therefore not be regarded as a pathology or disease, but rather as the normal, physiologic response to sustained caloric surplus As a consequence of the high level of lipid accumulation in insulin target tissues including skeletal muscle and liver, it has been suggested that exclusion of glucose from lipid-laden cells is a compensatory defense against further accumulation of lipogenic substrate. Other prevailing thoughts that insulin resistance can be an evolutionary adaptation include the thrifty gene hypothesis. This hypothesis raises the point that if there is a genetic component to insulin resistance and Type 2 diabetes, these phenotypes should be selected against. Neel postulates that originally in times of increased famine in ancient humans' ancestors, genes conferring a mechanism for increased glucose storage would be advantageous. In the modern environment today, however, this is not the case. Evidence is contradictory to Neel in studies of the Pima Indians, which indicate that the people with higher insulin sensitives tended to weigh the most and conversely people with insulin resistance tended to weigh less on average in this demographic. Modern hypotheses suggest that insulin metabolism is a socio-ecological adaptation with insulin being the means for differentiating energy allocation to various components of the body and insulin sensitivity an adaptation to manipulate where the energy is diverted to. The Behavioral Switch Hypothesis posits that insulin resistance results in two methods to alter reproductive strategies and behavioral methods. The two strategies are coined as "r to K" and "soldier to diplomat. This has demonstrated weight gain in the fetus, but not the mother indicating a method of increased parental investment K strategy. In the "soldier to diplomat" the insensitivity of skeletal muscle to insulin could divert the glucose to the brain, which does not require insulin receptors. This has shown increases in cognitive development across various studies. Contents move to sidebar hide. Article Talk. Read Edit View history. Tools Tools.

If cells become too resistant to insulin, this increases blood sugar levels, and if left untreated or poorly managed, leads to type 2 diabetes. Now, in someone who is insulin resistant, the body is not properly secreting insulin into the bloodstream; this means the body is unable to properly convert food into energy. As you can imagine, this is a problem! The body needs energy and it needs blood sugar regulation to prevent severely high or low blood sugar levels — which can lead to hyperglycemia high blood pressure and ultimately, type 2 diabetes. What are the 3 most common symptoms of undiagnosed diabetes? How does a person know if he or she is insulin resistant? Some people who have insulin resistance may experience:. Because insulin is an essential hormone in the body, insulin resistance is related to a number of health conditions, including type 1 diabetes, type 2 diabetes, prediabetes and PCOS. Untreated insulin resistance can lead to type 2 diabetes. When a person continues to eat high calorie, high sugar foods, and insulin is constantly being pumped into the bloodstream, the body cells stop responding to insulin — making them insulin resistant. People who have type 1 diabetes who are also insulin resistant will require a higher dosage of insulin in order to regulate blood sugar than those who are just insulin resistant.
