What Can Cause Hyperinsulinemia?

Hyperinsulinemia, The Danger Of Too Much Insulin

Hyperinsulinemia, The Danger Of Too Much Insulin

Hyperinsulinemia is not another word for type 2 diabetes or even for borderline diabetes. It literally means there is too much insulin in your blood. If you have high blood sugar, that is called hyperglycemia. Too little sugar is hypoglycemia. Both can be found in a diabetic. Your pancreas, or more precisely the beta cells inside it, make the two hormones that keep glucose at a safe and steady level in your blood. Hormones make them part of your endocrine system. Endocrine glands release the hormones that affect every organ and cell, and they always come in pairs so they can balance, or turn on and off effects like your bone growth, mood and digestion. An endocrinologist is the kind of doctor who specializes in endocrine systems. That's why type 2 diabetic doctors are endocrinologists. They study the disease and its symptoms, and they have learned how to treat those symptoms. They can identify hyperinsulinemia, and they know what it does. Elevated insulin in the blood causes an increased inflammatory effect in every organ of the body. That doesn't sound terrible until you look at problems caused by inflammation. Here are just a few: Crohn's disease, rheumatoid arthritis, chronic fatigue syndrome, diabetes, Alzheimer's and Parkinson's. In hyperinsulinemia your pancreas is putting out larger amounts of insulin than your cells can use. The excess insulin builds up in your blood. Sometimes this is because of insulin resistance in the cells. Doctors know insulin resistance is connected to the metabolic syndrome. For diabetics this compounds the problems caused by high blood sugar. Elevated sugar in your blood damages blood vessels and spreads candidal infections through your bloodstream. Hyperglycemic symptoms are not as obvious as those for hypoglycemia, which is why it is Continue reading >>

Congenital Hyperinsulinism

Congenital Hyperinsulinism

General Discussion Congenital hyperinsulinism (HI) is the most frequent cause of severe, persistent hypoglycemia in newborn babies, infants, and children. In most countries it occurs in approximately 1/25,000 to 1/50,000 births. About 60% of babies with HI are diagnosed during the first month of life. An additional 30% will be diagnosed later in the first year and the remainder after that. With early treatment and aggressive prevention of hypoglycemia, brain damage can be prevented. However, brain damage can occur in children with HI if the condition is not recognized or if treatment is ineffective in the prevention of hypoglycemia. Insulin is the most important hormone for controlling the concentration of glucose in the blood. As food is eaten, blood glucose rises and the pancreas secretes insulin to keep blood glucose in the normal range. Insulin acts by driving glucose into the cells of the body. This action of insulin maintains blood glucose levels and stores glucose as glycogen in the liver. Once feeding is completed and glucose levels fall, insulin secretion is turned off, allowing the stores of glucose in glycogen to be released into the bloodstream to keep blood glucose normal. In addition, with the switching off of insulin secretion, protein and fat stores become accessible and can be used instead of glucose as sources of fuel. In this manner, whether one eats or is fasting blood glucose levels remain in the normal range and the body has access to energy at all times. This close regulation of blood glucose and insulin secretion does not occur normally in people who have HI. The beta cells in the pancreas, which are responsible for insulin secretion, are blind to the blood glucose level and secrete insulin regardless of the blood glucose concentration. As a resu Continue reading >>

Hyperinsulinemia: Symptoms, Treatments, And Diet

Hyperinsulinemia: Symptoms, Treatments, And Diet

The typical cause of hyperinsulinemia is insulin resistance . Insulin resistance is what happens when your body doesnt respond correctly to insulin. This incorrect response causes your body to need the pancreas to produce more insulin. As your pancreas makes more insulin, your body continues to resist and respond incorrectly to the higher levels of insulin. Your pancreas will continually need to make more to compensate. Eventually, your pancreas wont be able to keep up with the amount of insulin your body needs to keep your blood sugar at a healthy level. Insulin resistance can eventually lead to type 2 diabetes . Less common causes of this condition are insulinoma and nesidioblastosis. Insulinoma is a rare tumor of the pancreas cells that produce insulin. Nesidioblastosis is when the pancreas produces too many cells that make insulin. Hyperinsulinemia may also develop after having gastric bypass surgery. The theory is that the cells have become too large and active for the body, but the body has changed significantly after the bypass. Doctors arent fully sure why this happens. Hyperinsulinemia is usually diagnosed through a blood test taken when youre fasting. It may also be diagnosed when your doctor is checking for other conditions like diabetes. Treatment for hyperinsulinemia begins by treating whatever is causing it. This is particularly true if your condition is caused by insulinoma or nesidioblastosis. Your treatment may also include a combination of medication, lifestyle changes, and possibly surgery. These lifestyle changes include diet and exercise. The medications used to treat this condition are the same or similar to the medications used to treat diabetes. However, medication should be used only if diet and exercise arent enough to control the condition. S Continue reading >>

Hypertension And Hyperinsulinemia

Hypertension And Hyperinsulinemia

Hypertension is defined as the sustained elevation of either or both systolic and diastolic blood pressure while at rest. There are several different classifications of hypertension, but the two main categories are primary, also called essential hypertension, and secondary hypertension. The majority of all those diagnosed with hypertension fall under the primary category while only a small percentage are classified as secondary hypertensive. Secondary hypertension is the result of some other condition or disease where as primary Hypertension is said, by conventional medicine, to have no identifiable cause for development. An overwhelming number of studies have revealed that diet, obesity and vitamin and mineral deficiencies are related to primary hypertension. Changes in lifestyle and the uses of specific supplements have proven to be extremely effective in the treatment and reversal of mild primary hypertension and could be considered prior to the use of prescription drugs Hypertension is strongly associated with the development of cardiovascular disease and is one of the major factors in the incidences of heart attacks in both the diabetic and non-diabetic population. It can also contribute to the progression of atherosclerosis. Numerous studies show a definite correlation between hypertension, diabetes, hyperglycemia, atherosclerosis and cardiovascular disease.[i] [ii] We are most interested in the links between diabetes and hypertension and how to prevent and or treat them accordingly. Type I diabetes patients usually develop secondary hypertension while Type II patients are associated with primary hypertension. Secondary hypertension in Type I patients is usually the result of nephropathy often caused by chronic hyperglycemia. Type II diabetes patients can also dev Continue reading >>

Peter Van Buren, Martin M. LeWinter, in Heart Failure: A Companion to Braunwald's Heart Disease (Second Edition) , 2011 Hyperinsulinemia is present only in type 2 DM, and therefore does not contribute to cardiomyopathy in type 1 DM. Cardiac hypertrophy is perhaps the most important consequence of hyperinsulinemia.24,79,80 Patients with DM have been shown to have increased cardiac mass independent of co-existent hypertension.79,80 Multiple mechanisms are probably responsible for hypertrophy in DM.24 PKC signaling is enhanced by hyperinsulinemia and, as mentioned earlier, can directly contribute to the hypertrophic response.70,71 Insulin acutely augments glucose uptake via activation of a tyrosine kinase receptormediated Akt-1 pathway81 (Figure 26-7). Akt-1 inactivates glycogen synthase kinase-3, an inhibitor of nuclear factor in activated lymphocytes (NFAT-3), a key hypertrophy mediator. Hyperinsulinemia-mediated increased sympathetic activation may also function to augment Akt-1 activity.81 The tyrosine kinase pathway also contributes to PKC activation (see Figure 26-7). Finally, insulin is an activator of the MAPK hypertrophic pathway.82 Johan Verhaeghe, Roger Bouillon*, in Principles of Bone Biology (Third Edition) , 2008 Hyperinsulinemia is the compensatory answer to hepatic and muscle insulin resistance; when inadequate, impaired fasting glucose and/or postload hyperglycemia (impaired glucose tolerance) ensue. Several population studies have demonstrated a correlation between on the one hand fasting insulin, the HOMA insulin resistance index, and/or postchallenge glucose and insulin concentrations and on the other hand the aBMD at the hip and/or the spine (Barrett-Connor and Kritz-Silverstein, 1996; Dennison et al., 2004; Stolk et al, 1996; Thomas et al., 2001).

Understanding Hyperinsulinemia

Understanding Hyperinsulinemia

Put plainly Hyperinsulinemia means that the amount of insulin in the blood is far higher than what is considered normal. It is not Diabetes but it is often associated with type 2 Diabetes. Hyperinsulinemia is often caused by insulin resistance. It can also be caused by a tumor affecting the pancreas or something called nesidioblastosis, meaning the pancreas has an excess of insulin producing cells. 1 Insulin is required by our body to regulate blood sugars, the pancreas is responsible for producing the necessary amount of insulin at any given time. Someone suffering from Hyperinsulinemia has trouble controlling blood sugar levels, requiring immense amounts of insulin to be produced in order to maintain a normal blood sugar level. Insulin resistance can often lead to the development of type 2 Diabetes because the pancreas cannot keep up with the huge amounts of insulin required to regulate blood sugar levels. Hidden Dangers Of This Under-Diagnosed Condition Hyperinsulinemia has no symptoms or signs unless it causes hypoglycemia or low blood sugar. This makes it a very worrying condition that is most definitely affecting many more people than are being diagnosed. Leading to the development of type 2 Diabetes, causing severe imbalances in insulin and blood sugar levels which can also have significant health repercussions on every bodily system. Hyperinsulinemia is associated with Metabolic Syndrome, conditions such as hypertension, obesity, glucose intolerance and dyslipidemia can all be a result of Hyperinsulinemia. It is not fully understood whether Hyperinsulinemia causes obesity or obesity is the cause of Hyperinsulinemia, or perhaps both. Obesity causes an excess of adipose tissue, which is known to secrete various cytokines, hormones and metabolites that may contrib Continue reading >>

Causes Of Insulin Resistance And Hyperinsulinism

Home Conditions Insulin Resistance Causes of Insulin Resistance and Hyperinsulinism Causes of Insulin Resistance and Hyperinsulinism The Causes of Insulin Resistance and Hyperinsulinism The main reason for hyperinsulinism or excessive release of insulin is insulin resistance . Most of the time people get insulin resistance as a result of eating too much and being overweight. Even if you are overweight, theyre ways to increase insulin sensitivity . Usually, if people lose weight their insulin resistance will go down. One should realize that insulin resistance is a broad term and that you could be insulin sensitive in one way and resistant in another. Fat, muscle and the liver store glucose . You could be insulin sensitive in your muscles and resistant in your fat cells, in which case youll be muscular and lean. This isnt always optimally healthy. For example, if you have elevated levels of the inflammatory cytokine TNF-alpha it will cause insulin resistance in fat cells but not muscle cells. This isnt a good situation even though aesthetically youll look good. Sometimesthin people can also have insulin resistance. PCOS is a relatively common disorder among women, affecting up to 10% of women 12-45. Thin women with PCOS also have insulin resistance. There is also research that suggests that there is a male version of PCOS experienced by a certain percentage of men. PCOS and its associated IR is much easier to detect in women because of overt androgenic signs like facial hair growth, alopecia (balding) and fertility issues, but males can have a similar kind of issue and wouldnt be noticeable because men all healthy men have facial hair, etc However, the symptoms can manifest itself as premature balding. In thin people, IR can in part be caused by an inefficient conversion Continue reading >>

Congenital Hyperinsulinism - Genetics Home Reference

Congenital Hyperinsulinism - Genetics Home Reference

What does it mean if a disorder seems to run in my family? What is the prognosis of a genetic condition? Congenital hyperinsulinism affects approximately 1 in 50,000 newborns. This condition is more common in certain populations, affecting up to 1 in 2,500 newborns. What information about a genetic condition can statistics provide? Why are some genetic conditions more common in particular ethnic groups? Congenital hyperinsulinism is caused by mutations in genes that regulate the release (secretion) of insulin, which is produced by beta cells in the . Insulin clears excess sugar (in the form of glucose) from the bloodstream by passing glucose into cells to be used as energy. congenital hyperinsulinism lead to over-secretion of insulin from beta cells. Normally, insulin is secreted in response to the amount of glucose in the bloodstream: when glucose levels rise, so does Congenital hyperinsulinism can have different inheritance patterns, usually depending on the form of the condition. At least two forms of the condition have been identified. The most common form is the diffuse form, which occurs when all of the beta cells in the pancreas secrete too much insulin. The focal form of congenital hyperinsulinism occurs when only some of the beta cells over-secrete insulin. congenital hyperinsulinism is inherited in an , which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. Less frequently, the diffuse form is inherited in an , which means one copy of the altered gene in each cell is sufficient to cause the disorder. congenital hyperinsulinism is more complex. For most genes, both copies are t Continue reading >>

Hyperinsulinemia

Hyperinsulinemia

Tweet Hyperinsulinemia is often associated with type 2 diabetes, but it isn’t diabetes as such. Hyperinsulinemia means that the amount of insulin in the blood is higher than considered normal amongst non-diabetics. When a person has hyperinsulinemia they have a problem controlling blood sugar, meaning that the pancreas has to secrete larger amounts of insulin to keep blood sugar at a normal level. How is hyperinsulinemia caused? Insulin resistance is the primary cause of hyperinsulinemia, with the pancreas compensating by producing more insulin. Insulin resistance of this type can lead to the development of type 2 diabetes, which occurs when the pancreas cannot secrete the insulin required to maintain normal blood glucose levels. In more rare cases, hyperinsulinemia may be caused by a tumour of the insulin-producing cells of the pancreas (insulinoma). It may also be caused by excessive numbers of insulin-producing cells in the pancreas (nesidioblastosis). What are the risks of having hyperinsulinemia? There are a number of risks involved in having hyperinsulinemia which include: Higher triglyceride levels High uric acid Hardening of the arteries (artherosclerosis) Weight gain Hypertension Type 2 diabetes The sooner hyperinsulinemia is diagnosed, which may be in the form of pre-diabetes or type 2 diabetes, the sooner the risks or extent of the above can be reduced. What are the symptoms of hyperinsulinemia? Although hyperinsulinemia often has little clear indicator, hyperinsulinemia symptoms may include: Weight gain Cravings for sugar Intense hunger Feeling frequently hungry Difficulty concentrating Feeling anxious or panicky Lacking focus or motivation Fatigue How is hyperinsulinemia treated? Medical treatment, in the form of diabetes medication, may help to relieve t Continue reading >>

According to Genetics Home Reference, this can happen as a result of genetics, called familial hyperinsulinism, or it can occur in response to insulin resistance, which causes the pancreas to overproduce insulin in an effort to maintain normal blood sugar levels. Insulin is a hormone that is released in response to glucose, or sugar, in the blood stream, making diet a major part of treatment. Doctors may not identify hyperinsulinism.Photo Credit: Monkey Business Images/Monkey Business/Getty Images The identification, or diagnosis, of hyperinsulinism often goes undetected by you or your doctor. Explained by the January 2013 "Gene Reveiw," hyperinsulinism does not usually present itself with signs or symptoms until low blood sugar occurs, also known as hypoglycemia. Even then, signs of hypoglycemia are somewhat generic resulting in fatigue, weakness, dizziness or irritability, which can point to a number of conditions. In infants, hyperinsulinism symptoms include poor feeding and seizures. Diet is important to keep healthy.Photo Credit: olgakr/iStock/Getty Images When combating abnormalities in glucose -- sugar -- or insulin regulation in the body, diet intake is always a concern and should be closely monitored.

Hyperinsulinemia

Hyperinsulinemia

Hyperinsulinemia, or hyperinsulinaemia is a condition in which there are excess levels of insulin circulating in the blood relative to the level of glucose. While it is often mistaken for diabetes or hyperglycaemia, hyperinsulinemia can result from a variety of metabolic diseases and conditions. While hyperinsulinemia is often seen in people with early stage type 2 diabetes mellitus, it is not the cause of the condition and is only one symptom of the disease. Type 1 diabetes only occurs when pancreatic beta-cell function is impaired. Hyperinsulinemia can be seen in a variety of conditions including diabetes mellitus type 2, in neonates and in drug induced hyperinsulinemia. It can also occur in congenital hyperinsulism, including nesidioblastosis. Hyperinsulinemia is associated with hypertension, obesity, dyslipidemia, and glucose intolerance.[1] These conditions are collectively known as Metabolic syndrome.[2] This close association between hyperinsulinemia and conditions of metabolic syndrome suggest related or common mechanisms of pathogenicity.[1] Hyperinsulinemia has been shown to "play a role in obese hypertension by increasing renal sodium retention".[1] In type 2 diabetes, the cells of the body become resistant to the effects of insulin as the receptors which bind to the hormone become less sensitive to insulin concentrations resulting in hyperinsulinemia and disturbances in insulin release.[3] With a reduced response to insulin, the beta cells of the pancreas secrete increasing amounts of insulin in response to the continued high blood glucose levels resulting in hyperinsulinemia. In insulin resistant tissues, a threshold concentration of insulin is reached causing the cells to uptake glucose and therefore decreases blood glucose levels. Studies have shown that Continue reading >>

Understanding Hyperinsulinemia

Understanding Hyperinsulinemia

Hyperinsulinemia is the state of having increased fasting insulin level in the blood that is beyond normal level. Although it is often associated with type 2 diabetes, hyperinsulinemia does not necessarily mean that one is diabetic. Hyperinsulinemia is a condition when the body produces too much insulin than what it usually needs. Insulin is a hormone produced by the pancreas, an endocrine organ located in the upper portion of the abdomen. Its function is to regulate the entry of sugar (glucose) into the cells, which use it to produce energy, and to store excess sugar in the liver for later use. The body detects an increase in sugar in the blood when food is ingested, which signals the pancreas to produce insulin. An increase in insulin allows sugar to enter the cells to be converted to energy. The reduction of sugar levels in the blood triggers the pancreas to stop producing insulin, until more food is ingested. Insulin therefore regulates blood sugar levels, thus preventing a condition known as hyperglycemia (high blood sugar levels), which is often associated with type 2 diabetes. However, some people tend to produce too much insulin compared to other people, even when they are in a fasting state, signalling hyperinsulinemia. This condition is strongly linked to an underlying condition, which could lead to other health problems. The most common cause of hyperinsulinemia is insulin resistance, a condition where the cells are resistant to insulin effects, and are thereby unable to utilize glucose. To compensate, the pancreas compensates by producing more insulin. Insulin resistance is a condition that covers a wide clinical spectrum, including obesity, glucose intolerance (prediabetes), diabetes, and metabolic syndrome. These disorders, in turn are linked with various Continue reading >>

Hyperinsulinemia Symptoms

Hyperinsulinemia Symptoms

Hyperinsulinemia is a condition where the blood insulin level is higher than what is considered normal in people without diabetes. Although hyperinsulinemia is not diabetes, the condition is often associated with type 2 diabetes. People with hyperinsulinemia have difficulty maintaining a normal blood sugar level, which means the pancreas has to produce increasing amounts of insulin in order to control it. The primary cause of hyperinsulinemia is insulin resistance, which occurs when the insulin level remains high enough over a long period for the body to become less sensitive to the hormone. This means that the body’s usual response to a given amount of insulin is decreased, which results in the pancreas secreting higher levels of insulin in order for the hormone to exert its usual effects. The pancreas produces increasing levels of insulin until eventually it can no longer produce enough to meet the body’s needs. This leads to a rise in the blood sugar level and insulin resistance is therefore a risk factor for the development of diabetes. In rare cases, hyperinsulinemia may be caused by the presence of a tumor in the insulin-producing cells (islets of Langerhans) of the pancreas. This tumor is referred to as an insulinoma. Another rare cause is a condition called nesidioblastosis, a genetic disorder where abnormal islets of Langerhans produce an excess of insulin. Insulin resistance may occur in response to the body’s endogenous insulin or exogenous insulin given via injection. Insulin resistance is closely associated with inflammation and is thought to be caused by cytokine release disrupting the usual action of insulin. The chronic inflammation seen in obesity can therefore increases the risk of type 2 diabetes. Symptoms of insulin resistance One of the first Continue reading >>
