Lipids In Diabetes Ecab

The insulin resistance syndrome can be defined as insulin resistance, compensatory hyperinsulinemia, and their associated co-morbidities. Clinically, the term insulin resistance syndrome describes a constellation of abnormalities such as obesity, hypertension, dyslipidemia, type 2 diabetes/hyperglycemia, and coronary artery disease. Insulin is responsible for glucose uptake into the body cells and tissues. The response of the cells to insulin varies from individual to individual. In some individuals, the tissue response to insulin may be diminished. This means that even with adequate levels of insulin, the glucose uptake into the cells and tissues is not optimal. This results in a compensatory over-secretion of insulin from the pancreas. The persistence of high levels of insulin in the blood or hyperinsulinemia is thought to be responsible for some of the abnormalities associated with this condition. However, the exact causal association of the condition with these disorders and the pathophysiology of their evolution are unclear. The most common underlying mechanism proposed is increased free fatty acids from abdominal fat in individuals with central obesity. This leads to deranged insulin signaling, reduced muscular glucose uptake, increased triglyceride synthesis, and hepatic gluconeogenesis. A genetic basis of the disease as well as several other factors such as tumor necrosis factor-α, adiponectin, leptin, Interleukin-6, and some adipokines have also been implicated. Insulin resistance syndrome is of clinical significance because of its association with potentially debilitating conditions that contribute to long-term morbidity and even mortality of the individual. People with insulin resistance syndrome are at an increased risk of developing type 2 diabetes, hypertension, dyslipidemia, myocardial infarction, polycystic ovarian disease, and fatty liver. In this book, we have tried to collate the experiences of the pioneers of this field on the subject and provide the reader a comprehensive view on the topic along with practical management points, which we are sure will benefit the physicians in their clinical practice. The contributors have focused on the condition as is prevalent in our subcontinent and have tried to give an insight on the issues pertaining to the same with a topical flavor.

Type 2 diabetes mellitus is associated with a greater risk of developing atherosclerotic macrovascular diseases like myocardial infarction, stroke, and peripheral vascular disease. There is 2- to 4-fold increased risk of atherosclerotic heart disease and stroke in diabetic patients compared to non-diabetic patients. As the prevalence of type 2 diabetes is increasing rapidly, this diabetes related atherosclerotic disease is predicted to be a major public health problem. Atherosclerosis is a complex process and in diabetic patients, it behaves differently with increased lesion progression and severity. This accelerated atherosclerotic process in diabetics is explained on the basis of several risk factors like hyperglycemia, dyslipidemia, accelerated formation of advanced glycation end products, increased oxidative stress, and genetic factors. It is difficult to establish precisely the elements responsible for this atherosclerosis in diabetics, but by epidemiological, clinical, and by animal studies, it has been possible to get an idea of this problem in diabetics. Of the several risk factors for atherosclerosis in diabetes, dyslipidemia is the leading one, and an insight into the pathophysiologic relation of isolated triglyceridemia in Indian diabetics with the identification of the targets for control of lipids in diabetes (practical vs. ideal) needs to be well understood by the treating physician. This book is designed to address such issues with supportive typical clinical scenarios, with which the readers will be able to identify. Thus, it provides an excellent opportunity to widen one’s perspective in this area.

Diabetes is one of the most important non-communicable lifestyle diseases. Diabetes is a multifaceted disorder which possibly influences and impacts body pathophysiology by different mechanisms and in varied ways. Diabetes has a very distinguished impact on cardiovascular system and plays a detrimental role in development of cardiovascular disorders. Metabolic memory is used to describe the impact of exposure to glucotoxicity, lipotoxicity and other metabolic disturbances, either as an adverse or a beneficial cell response which determines the later development of vascular complications. Terms such as metabolic imprint, legacy effect, glycemic memory or latent hyperglycemic damage are also used. Diabetes has significant impact on different facets of life. Diabetes has a distinguished but significant impact on development of various cancers. Diabetes has a positive, negative and even neutral impact on pathogenesis and progression of cancer depending upon the tumor site. On the contrary, cancer also has a significant effect on diabetes development and management. These facets tend to get overlooked in the study of diabetes development and management. All these aspects are being thoroughly covered in this project so as to facilitate better management of diabetics.

Critical Issues and Diabetes - ECAB - E-Book

Cell health depends on a steady supply of fuel from glucose and free fatty acids. Both these major fuels are regulated by insulin. Cells in the muscle, liver, and fat need insulin to receive glucose, and hence do not become exposed to high blood glucose levels when the blood sugars are high and insulin levels are low. The lack of insulin slows the movement of glucose into these cells, and probably spares them from damage when blood sugars are high. However, other cells such as those in the brain, nervous system, heart, blood vessels and kidneys pick up glucose directly from the blood without using insulin. These cells, except the brain, are more prone to damage from high blood sugars because they become exposed to high internal levels of glucose. This to quite an extent explains why damage tends to occur in specific organs such as in nerve and kidney cells, and in small blood vessels like those in the eyes. This project on the organ damage in diabetes is an attempt to elaborate on the various factors to be considered in managing these patients, the pointers for early diagnosis and prevention of the same.

Diabetes management, outcomes and prognosis are majorly affected by the lifestyle exercised by the diabetics. Diabetes has significant impact on the different facets of life. These facets tend to get overlooked in the management. The inter-relation of diabetes and marriage, sleep, travel, commute and uneven working hours seem to be trivial part of managing diabetes but are extremely important for a perfect recovery and management of the patient. Patients travelling with diabetes need to consider how to adapt their treatment programs to unfamiliar foods, irregular schedules, and varying amounts of exercise. Diabetes will be involved at every step of married life including vacations, outings, going to the movies, as well as intimate moments. Sleep and diabetes are interconnected. Sleep disorders have a slight but significant impact on diabetes management and it should be focused while attending a diabetic with sleep disorders. Shift workers make a special segment of diabetics, whose glucose monitoring and control need to be tailored in a special manner. With change in circadian rhythm and sleep pattern, diabetes management needs to be adjudged and adjusted. The main risks that arise in driving from having diabetes are hypoglycemia and the long term complications. All these aspects are being thoroughly covered in this book so as to facilitate better management of diabetes.

The pathogenesis of microvascular complications is complex and multifactorial. Yet, hyperglycemia emerges as the most important single cause, which has been proved by the Diabetes Control and Complications Trial (DCCT). Thus, the importance of protecting the body from hyperglycemia cannot be overstated; the direct and indirect effects on the human vascular tree are the major source of morbidity and mortality in both type 1 and type 2 diabetes. Generally, the injurious effects of hyperglycemia are separated into macrovascular complications (coronary artery disease, peripheral arterial disease, and stroke) and microvascular complications (diabetic nephropathy, neuropathy, and retinopathy). It is important for physicians to understand the relationship between diabetes and vascular disease because the prevalence of diabetes continues to increase in our country, and the clinical requirements for primary and secondary prevention of these complications are also expanding.

Gestational diabetes mellitus (GDM) is classically seen in about 5–8% of the pregnant women. The condition appears to be caused by the same broad spectrum of physiological and genetic peculiarities that characterize diabetes outside of pregnancy. These women with GDM are also otherwise at high risk of having or developing diabetes even when not pregnant. The controversies regarding the diagnosis, management, and prevention of diabetes in pregnancy pose specific problems in clinical practice such as how to clinch the diagnosis, when to introduce therapy, what therapy to introduce, and how to predict the future course of the condition. This book is designed to address such questions with supportive typical clinical scenarios, with which all readers will be able to identify. Thus it provides an excellent opportunity to widen one’s perspective in this area.
