Insulin Resistance and the Polycystic Ovary Syndrome: Mechanism and Implications for Pathogenesis*. ANDREA DUNAIF. Pennsylvania State University ...Since the report by Burghen et al. (7) in 1980 that PCOS was associated with hyperinsulinemia, it has become clear that the syndrome has major metabolic as well as reproductive morbidities. The recognition of this association has also instigated extensive investigation of the relationship between insulin and gonadal function (1, 8 –11). This review will summarize our current understanding of insulin action in PCOS, address areas of controversy, and propose several hypotheses for this association. Abnormalities of steroidogenesis and gonadotropin release will not be discussed in detail; these changes have been reviewed recently by Erhmann and colleagues (12) and by Crowley (13), respectively. The association between a disorder of carbohydrate metabolism and hyperandrogenism was first described in 1921 by Achard and Thiers (14) and was called “the diabetes of bearded women (diabete des femmes a barbe).” The skin lesion, acanthosis nigricans, was reported to occur frequently in women with hyperandrogenism and diabetes mellitus by Kierland et al. (15) in 1947. Brown and Winkelmann (16) noted in 1968 that it was insulin-resistant diabetes mellitus, and a genetic basis was suggested by reports of affected sisters (17), including a pair of identical twins who also had acromegaloid features (18). Several additional syndromes with distinctive phenotypic features, acanthosis nigricans, hyperandrogenism, and insulin-resistant diabetes mellitus have been identified (Table 1)....
triglycerides in the blood. Having several of these problems is called metabolic syndrome or insulin resistance syndrome, formerly called syndrome X....Insulin resistance is a condition in which the body produces insulin but does not use it properly. Insulin, a hormone made by the pancreas, helps the body use glucose for energy. Glucose is a form of sugar that is the body’s main source of energy. The body’s digestive system breaks food down into glucose, which then travels in the bloodstream to cells throughout the body. Glucose in the blood is called blood glucose, also known as blood sugar. As the blood glucose level rises after a meal, the pancreas releases insulin to help cells take in and use the glucose....
OBJECTIVEdAlthough insulin resistance (IR) may underlie associations between depressive symptoms and diabetes, previous findings have been contradictory ...Depressive symptoms are associated with type 2 diabetes (1) and the metabolic syndrome (2,3), and insulin resistance (IR) is thought to be the underlying factor. However, previous findings have been conflicting because depressive symptoms have been reported to be associated with both higher IR (4) and lower IR (5), whereas some studies have reported null associations (6,7). We examined associations of depressive symptoms with IR and insulin secretion in individuals without diabetes....
Far too many care providers refuse to believe that these conditions exist, in spite of all the research to the contrary. Reactive hypoglycemia is not the same as fasting hypoglycemia, which is low blood sugar that occurs when you don’t eat. Reactive hypoglycemia is not always picked up on routine medical tests. It usually occurs two to three hours after a high carbohydrate meal, overstimulating the release of insulin, which triggers a compensatory adrenalin response. Hypoglycemia appears to induce abnormalities in decision-making processes (Blackman, Towle, Lewis et al. 1990) and can contribute to our fibrofog. Some symptoms of hypoglycemia (tremor, palpitations, anxiety, sweating, hunger, paresthesias) are due to changes caused by the response of the autonomic nervous system. Other symptoms (confusion, sensation of warmth, weakness or fatigue, severe cognitive failure, seizure, coma) are the results of brain glucose deprivation itself (Cryer, 1999). Coexisting RHG makes treatment of FMS and CMP extremely difficult. Myofascial TrP activity is so aggravated by it that it doesn’t make sense to treat TrPs unless the hypoglycemia is treated also (Simons 1989). When your body no longer responds appropriately to the insulin that you produce, you have developed IR. Insulin resistance can be serious. Activation of the HPA axis and the central sympathetic nervous system can cause endocrine abnormalities, insulin resistance, and other symptoms leading to disease states, including Type 2 diabetes (Bjorntorp, Holm and Rosamund, 1999). Normal blood sugar levels with coexisting high insulin, associated with obesity or problems in fat metabolism, could be considered as "normoglycemic diabetes", which will develop in time toward hyperglycemia (Ionescu-Tirgoviste, 1998)....ties, insulin resistance, and other symptoms leading to disease states, including.

Polycystic Ovary Syndrome (PCOS), Insulin Resistance (IR), Type 2 Diabetes, & the Metabolic. Syndrome are common conditions, frequently in the news ...What is Polycystic Ovary Syndrome (PCOS)? PCOS is a common endocrine disorder, occurring in about 5% of reproductive-aged women (1). PCOS is a syndrome, not a specific disease. In medicine, a syndrome is a group of symptoms & signs that are recognized to be associated with each other but are without an understood common cause as is known to diseases. (For example, in most cases, high blood pressure [hypertension] is really part of a syndrome; it is associated with being overweight, not exercising, ethnicity, & age. However, rare cases of hypertension can be caused by a specific disease such as narrowing of the artery to the kidney – in this case, the hypertension can be cured by a specific treatment [widening the artery].)...
Insulin resistance is a condition that increases your chances of developing type 2 diabetes and heart disease. When you have insulin resistance, your body has problems responding to insulin. Eventually, your blood glucose (sugar) levels rise above normal. The good news is that cutting calories, adding physical activity to your daily routine, and losing weight can reverse insulin resistance and lessen your chances of getting type 2 diabetes and heart disease....Insulin’s job is to help the body use glucose for energy. It’s a hormone, one of the chemicals your body makes to help trigger or regulate processes in the body. Insulin is made by the pancreas, an organ located behind the lower part of the stomach. Your pancreas usually makes just the right amount of insulin to match the food you eat. Insulin acts as the doorman at the entrance to your cell. Food arrives at the door of a cell in the form of blood glucose. When your insulin is working effectively, it opens the door, just like a doorman. Then blood glucose enters the cell where it is used for energy....
Insulin Resistance and the. Polycystic Ovary Syndrome: Mechanism and Implications for Pathogenesis1. Andrea Dunaif. Pennsylvania State University College ...Its etiology remains unknown. Although there have been no specific populationbased studies, a 5–10% prevalence of this disorder in women of reproductive age is probably a reasonable conservative estimate. This is based as an upper limit on studies of the prevalence of polycystic ovaries, which found that 20% of self-selected normal women had polycystic ovary morphology on ovarian ultrasound (3). Many of these women had subtle endocrine abnormalities (3). The lower estimate is based on the reported 3% prevalence rate of secondary amenorrhea for 3 or more months (4) and the fact that up to 75% of women with secondary amenorrhea will fulfill diagnostic criteria for PCOS (5). PCOS women can also have less profound disturbances in menstrual function (1, 3, 6). Since the report by Burghen et al. (7) in 1980 that PCOS was associated with hyperinsulinemia, it has become clear that the syndrome has major metabolic as well as reproductive morbidities. The recognition of this association has also instigated extensive investigation of the relationship between insulin and gonadal function (1, 8, 9, 10, 11). This review will summarize our current understanding of insulin action in PCOS, address areas of controversy, and propose several hypotheses for this association. Abnormalities of steroidogenesis and gonadotropin release will not be discussed in detail; these changes have been reviewed recently by Erhmann and colleagues (12) and by Crowley (13), respectively....
To understand the autoimmune mediated insulin resistance syndrome. CASE PRESENTATION. PC is a 68-year-old female with a history Hashimoto's thyroiditis ...PC is a 68-year-old female with a history Hashimoto’s thyroiditis and mixed connective tissue disorder who developed rapid-onset, difficult to control diabetes mellitus. Several months before admission, she developed progressive weakness, polyuria leading to incontinence, polydypsia, and polyphagia, and had noted a 50 lb. weight loss. She also developed acanthosis nigricans in her inguinal and axillary regions and lower extremity paresthesias. She visited her PMD and was noted to have elevated serum blood glucose. She was started on oral hypoglycemic medications, but despite maximum doses of metformin, pioglitazone, and glipizide, she was unable to accomplish satisfactory glycemic control. She was started on subcutaneous insulin four months before her admission, but required ever increasing doses. Immediately prior to admission, she was receiving a total of 500 units of subcutaneous insulin daily, and her serum blood glucose readings were in the 400-500 mg/dL range....
Insulin Resistance and Depressive Symptoms in Young Adult Males: Findings. From Finnish Military Conscripts. MARKKU TIMONEN, MD, PHD, ILKKA ...To investigate whether the association between insulin resistance (IR) and depressive symptoms is present already in young adult males. The association between IR and depression has been poorly studied, although the existence of a connection of Type II diabetes with depression is well established. We previously demonstrated at epidemiological level in two groups of men aged 31 years and 61 to 63 years that IR is linked with depressive symptoms. Methods: In a cross-sectional study, involving 1054 healthy Finnish male military conscripts of about 19 years of age, IR was defined through homeostasis model assessment (HOMA-IR). The severity of the depressive symptoms was evaluated through a Finnish modification of the 13-item Beck Depression Inventory (R-BDI). Moderate-to-severe depressive symptoms were said to be present, if the R-BDI score was Ն8, and mild depressive symptoms were present if the R-BDI score was 5 to 7. Results: After adjusting for confounders, moderate-to-severe depressive symptoms increased the risk for IR, as defined by the highest decile of the HOMA-IR, up to 2.8-fold (odds ratio ϭ 2.8; 1.2– 6.5). Mild depressive symptoms were not significantly associated with IR. ...
