Clinically, Regulatingg resistance is recognized via the metabolic consequences associated Rehulating insulin resistance as described in Regulaating syndrome and insulin Reglating syndrome.
The gold standard inzulin measurement of insulin resistance is the Regulatkng glucose clamp technique. Indulin addition, several measures assess Retulating resistance based on serum glucose or insulin Regulatinv to a glucose challenge. The development of insulin resistance typically results in impaired glucose disposal into insulin-resistant tissues, especially skeletal muscle.
Consequently, in the presence of excess calorie consumption, more insulin is required to traffic glucose into these tissues. The resultant hyperinsulinemia further contributes to insulin resistance.
This vicious cycle continues until pancreatic beta-cell activity can no longer adequately meet the insulin demand created by insulin resistance, resulting in hyperglycemia. With a continued mismatch between insulin demand and insulin production, glycemic levels rise to those consistent with T2D.
Weight gain usually occurs alongside hyperinsulinemia but may be related more to a chronic caloric excess than hyperinsulinemia. The anabolic effect of insulin decreases as tissues become more insulin-resistant, and weight gain eventually slows.
Resistance to exogenous insulin has also been described. Patients requiring greater than units of exogenous insulin per day are considered severely insulin-resistant. In addition to T2D, the disease spectrum associated with insulin resistance includes obesity, cardiovascular disease, NAFLD, metabolic syndrome, and polycystic ovary syndrome PCOS.
These are all of great consequence in the United States, with a tremendous burden on the healthcare system to treat the direct and indirect conditions associated with insulin resistance. The microvascular complications of diabetes, such as neuropathy, retinopathy, and nephropathy, as well as the associated macrovascular complications of coronary artery disease [CAD], cerebral-vascular disease, and peripheral artery disease PADwill eventually consume the lion's share of the healthcare dollar as the disease progresses in severity.
The etiologies of insulin resistance may be acquired, hereditary, or mixed. The great majority of people with insulin resistance fall have an acquired etiology. In addition to the heritable components of the above etiologies of insulin resistance, there are several unrelated genetic syndromes with associated syndromic insulin resistance.
An alternative classification of insulin resistance exists and is based on the site of dysfunction with respect to the insulin receptor. This classification system includes pre-receptor, receptor, and post-receptor etiologies.
Epidemiologic assessment of insulin resistance is typically measured in relation to the prevalence of metabolic syndrome or insulin resistance syndrome. Criteria proposed by the National Cholesterol Education Program Adult Treatment Panel III national survey data suggest insulin resistance syndrome is widespread.
While obesity rates have increased considerably over the past 2 decades, this rapid increase in prevalence was not only associated with increased adiposity.
Hypertension, dyslipidemia, and limited physical activity also increased insulin resistance. While there has been a rapid rise in pediatric obesity and type 2 diabetes, no consensus has been reached on the pediatric population's diagnostic criteria for insulin resistance.
From a demographic standpoint, insulin resistance affects all races and ethnicities, with limited data on comparison between groups. The 3 primary sites of insulin resistance are the skeletal muscle, liver, and adipose tissue. In a state of chronic caloric surplus, the tissues in the body become resistant to insulin signaling.
The direct result of muscle insulin resistance is decreased glucose uptake by muscle tissue. Glucose is shunted from muscle to the liver, where de novo lipogenesis DNL occurs. With increased glucose substrate, the liver develops insulin resistance as well.
Higher rates of DNL increase plasma triglyceride content and create an environment of excess energy substrate, which increases insulin resistance throughout the body, contributing to ectopic lipid deposition in and around visceral organs.
In chronic caloric excess, muscle tissue accumulates intramyocellular fatty acids. Diacylglycerol is an intramyocellular fatty acid that signals energy excess within the cell. Diacylglycerol activates protein kinase C theta PKC-thetadecreasing proximal insulin signaling.
The direct result is decreased glucose transporter type 4 GLUT4 translocation to the cell membrane and reduced glucose uptake by the muscle tissue. The excess glucose in the blood is shunted to the liver to be metabolized or stored.
The liver is responsible for processing energy substrates. It packages, recirculates, and creates fatty acids and processes, stores, and creates glucose. If the liver becomes insulin-resistant, these processes are severely affected, resulting in significant metabolic consequences.
When skeletal muscle develops insulin resistance, excess glucose in the blood is shunted to the liver. When the liver tissue senses an excess of energy substrate, particularly in the form of diacylglycerol, a process similar to that in skeletal muscle occurs.
In the liver, the diacylglycerol content activates protein kinase C epsilon PKC-epsilonwhich decreases proximal insulin signaling. Excess glucose enters hepatocytes via insulin-independent pathways stimulating DNL via substrate push, creating more fatty acids from the glucose surplus.
The excess fatty acid is deposited in the liver or as ectopic lipid throughout the viscera. Additionally, immune-mediated inflammatory changes contribute to excess lipolysis from adipose tissue, which is re-esterified by the liver and further adds to circulating fatty acid and ectopic lipid deposition.
Finally, normal insulin-mediated suppression of gluconeogenesis is defective, and the liver continues to create more glucose, adding to the circulating glucose surplus. Using the hyperinsulinemic-euglycemic clamp technique, researchers determined that lipolysis is sensitive to insulin. The failure of insulin to suppress lipolysis in insulin-resistant adipose tissue, especially visceral adipose tissue, increases circulating free fatty acids FFAs.
Higher levels of circulating FFAs directly affect both liver and muscle metabolism, further exacerbating insulin resistance in these tissues and contributing to lipotoxicity-induced beta-cell dysfunction. The clinical presentation of insulin resistance is variable concerning both history and physical examination findings.
Common presentations include:. The gold standard for measuring insulin resistance is the hyperinsulinemic-euglycemic glucose clamp technique.
The amount of glucose required to reach a steady state reflects the exogenous glucose disposal needed to compensate for hyperinsulinemia. Insulin resistance calculation is based on whole-body glucose disposal and body size. The associated risks and complexity of the glucose clamp method limit its clinical usefulness.
As a result, multiple surrogate markers for insulin resistance have been developed and tested. The homeostatic model assessment for insulin resistance HOMA-IRbased on fasting glucose and fasting insulin levels, is a widely utilized measure of insulin resistance in clinical research.
Other measures based on fasting insulin include HOMA2, the Glucose to Insulin Ratio GIRand the Quantitative Insulin Sensitivity Index QUICKI. The McAuley Index utilizes fasting insulin and triglycerides.
Post-glucose challenge tests, done after an overnight fast, measure insulin and glucose response to a gram glucose load. Methods include the Matsuda Index and Insulin Sensitivity Index ISI.

You can improve this condition through lifestyle measures such as eating a balanced diet, staying active, and making an effort to maintain a moderate body weight. Chronic inflammation creates an environment where many harmful molecules prevent your body from responding to insulin. When a person has insulin resistance, their cells are less sensitive to insulin. |
| Insulin, Blood Sugar, and Type 2 Diabetes | Over time, insulin resistance can cause a range of health problems, including damage to the organs, muscles, limbs, and eyes. People with insulin resistance may receive a diagnosis of prediabetes , which can progress to type 2 diabetes. A person who has insulin resistance may need routine checkups with a doctor to ensure that they do not develop type 2 diabetes. Certain diet and lifestyle habits can affect the risks related to insulin resistance. Many people do not consume enough magnesium , calcium , fiber, and potassium , all of which are essential for regulating blood sugar levels. Therefore, it is important for people with insulin resistance to include plenty of foods rich in these nutrients in their diet. Additionally, although people with insulin resistance do not need to eliminate any foods from their diet, it is important to understand how certain foods may affect blood sugar levels. The following foods may support insulin sensitivity and reduce the risk of developing diabetes in general:. Certain foods are more likely to raise blood sugar. When this happens, the glucose remains in the blood, contributing to the health concerns that accompany consistently raised blood sugar, such as damage to the kidneys nephropathy or the limbs neuropathy. Limiting the following foods may help moderate blood sugar levels:. People can still eat foods on this list occasionally without negatively affecting long-term insulin sensitivity. The key is to limit these foods and replace them with more nutritious options when possible. By sticking to a nutritious, high fiber diet that is low in added sugars, a person can steadily improve their insulin sensitivity. Regular physical activity can also be helpful. Taking walks regularly or staying active throughout the day can significantly improve blood sugar regulation. For more science-backed resources on nutrition, visit our dedicated hub. Following a balanced diet plan that includes foods from a variety of cultures can improve insulin sensitivity. For example, the Mediterranean diet is a diet plan inspired by a specific culture that involves eating lots of seasonal, plant-based foods, such as fruits and vegetables, and using olive oil as the primary source of fat. People following this diet eat fish, lean meats, legumes, and nuts as main protein sources and enjoy dairy products in moderation. People following the Mediterranean diet also limit their intake of red meat and may consume red wine in moderation during meals. However, the Mediterranean diet is just one option for healthy eating. Other diet plans, such as the DASH Dietary Approaches to Stop Hypertension diet, may also help improve insulin resistance. This DASH diet provides daily and weekly nutritional goals and specifies the amounts of certain food groups a person should aim for each day, including fruits, vegetables, whole grains, low fat dairy, fats and oils, and meat, fish, or poultry. These diets can work well when a person combines them with other healthy lifestyle practices, such as stress management, adequate sleep of 7—9 hours per night, and regular physical activity. One way to manage blood sugar levels and reduce insulin resistance is to eat foods with a low glycemic index GI and glycemic load GL. GL accounts for both the GI of a food and the serving size. Carbohydrate foods with a high GI and GL can cause blood sugar spikes and put more demand on the body to produce insulin. Conversely, the digestive system processes foods with a low GI and GL slowly, which reduces blood sugar spikes. Eating foods with a low GI and GL is an excellent way to maintain balanced blood sugar levels and preserve insulin sensitivity. This category includes many fruits and vegetables, whole grains, and legumes. The pancreas releases insulin into the bloodstream. Insulin allows cells to absorb glucose, making sure that blood sugar levels remain at a safe level and that the cells in muscle, fat, liver, and other areas can get energy. When a person has insulin resistance, their cells are less sensitive to insulin. This means the pancreas has to produce more insulin to keep blood sugar levels stable. If the pancreas cannot keep up with the increased demand for insulin, blood sugar levels rise. If the cells cannot use all the excess glucose in the blood, a person will have high blood sugar levels. Over time, this could lead to type 2 diabetes and various other health concerns. Genetic factors may increase the risk of insulin resistance. However, lifestyle factors also make a difference. First, consuming too many calories can trigger weight gain. According to one study in middle-aged adults, weight gain increases the risk of insulin resistance. However, regular physical activity can counteract these effects. Second, various types of foods may have different effects on insulin resistance and blood sugar levels. A person should follow a balanced diet and prioritize foods high in fiber, protein, and heart-healthy fats. A doctor or dietitian may provide advice on which foods to eat to maintain steady blood sugar levels. Though a person can develop insulin resistance at any weight, having overweight or obesity may increase the chances of insulin resistance. People with excess fat around their waist and abdomen, in particular, are at a higher risk of developing insulin resistance. Excess fat around the waist might also relate to chronic inflammation. This can trigger a wide range of health problems, including insulin resistance. However, body weight is just one factor that may contribute to insulin resistance. Having overweight or obesity does not mean that a person will develop insulin resistance. A person can work with a doctor or dietitian for personalized guidance on whether diet and lifestyle changes may be beneficial. Not getting enough exercise can affect the way insulin regulates blood sugar levels. According to the American Diabetes Association , physical activity plays a vital role in keeping blood sugar levels steady. Aim for around 30 minutes of exercise per day, at least 5 days per week. A person can also add more activity to their daily routine by taking the elevator instead of the stairs, going for a walk during their lunch break, or using a standing desk. It is common in prediabetes, a condition that can progress to type 2 diabetes. Spanish Print. Minus Related Pages. Insulin acts like a key to let blood sugar into cells for use as energy. Insulin, Blood Sugar, and Type 2 Diabetes Insulin is a key player in developing type 2 diabetes. Here are the high points: The food you eat is broken down into blood sugar. Blood sugar enters your bloodstream, which signals the pancreas to release insulin. Insulin also signals the liver to store blood sugar for later use. Blood sugar enters cells, and levels in the bloodstream decrease, signaling insulin to decrease too. But this finely tuned system can quickly get out of whack, as follows: A lot of blood sugar enters the bloodstream. The pancreas pumps out more insulin to get blood sugar into cells. The pancreas keeps making more insulin to try to make cells respond. Do You Have Insulin Resistance? What Causes Insulin Resistance? How to Reverse Insulin Resistance If you have insulin resistance, you want to become the opposite—more insulin sensitive cells are more effective at absorbing blood sugar so less insulin is needed.

If you have insulin Regulating insulin sensitivity, ssensitivity may be sensitiviyt to reduce or even reverse Homemade remedies for sunburn by adopting healthy lifestyle habits Hydration for athletes as regular exercise Rwgulating a healthy diet. Insulin resistance occurs when cells in your body do not respond well to insulin. Insulin is produced by the pancreas and helps move glucose from the blood into cells, where it is used for energy. If you have insulin resistance, your pancreas must produce greater amounts of insulin to help maintain normal blood glucose levels. Eating foods that raise your blood sugar triggers the pancreas to release insulin to absorb the sugars.
