In addition, more than seventy-five percent of the people who have diabetes are at risk of dying because of heart disease, a situation that is indeed scary for those concerned. Diabetes mellitus Diabetes is a metabolic disorder that is categorized by chronic hyperglycaemia with instabilities of carbohydrate, fat and protein metabolism that come about due to defects in the secretion of insulin, the inaction of insulin or both in the body (Guthrie 2009, p.3). Diabetes mellitus affects people when the pancreas cannot secrete enough insulin, which is the hormone that the body uses to regulate the level of sugar in the blood or when the human body cannot effectively make use of the insulin produced. There are four types of diabetes namely type 1 diabetes, type 2 diabetes, secondary diabetes that may be due to damage to the pancreas and gestational diabetes, which occurs when a person is in pregnancy. Prevalence Estimates show that about 347 million in the world are suffering from diabetes while in the year 2004 alone, 3.4 million people died due to the effects related to diabetes complications mostly in low and middle-income economies. Projections by the World Health Organization indicate that diabetes will be the 7th leading cause of death in the year 2030 (Leroith 2012, p.43). The prevalence of diabetes generally in the world is increasing at a faster rate that can be attributed to the decreased physical activity and poor eating lifestyles. There is however little data on the prevalence of type 2 diabetes as this varies with other factors such as ethnicity and the degree at which a person accesses social amenities. Estimates on prevalence range in the region of 3.5 to 5% for example the International Diabetes Federation (IDF) suggest that 4% of persons in the age group of 20 to 79 years have type 2 diabetes in the US with a further death 4.2% in men who have diabetes and &.7% in women with similar condition. Therefore, type 2 is the most dominant type of diabetes since it accounts for about 90% of persons suffering from diabetic conditions. Diagnosed and Undiagnosed Diabetes among Persons of Age 20 Years and above in United States as at the year 2010 Source: National Diabetes Information Clearinghouse 2011 Diagnosed and Undiagnosed Diabetes Source: National Diabetes Information Clearinghouse 2011 Blood glucose regulation in the body Glucose is the essential source of energy for the body’s cells and tissues. In grownups without diabetes, glucose is maintained at a level of 70-99 mg/dL maintained by hormones, the metabolic requirements of the person and the nervous system. When a person is not eating, the liver stores glucose in the form of glycogen that helps to keep the body at a normal functioning range. At this moment, insulin is not at work and only the hormone glucagon breaks down the glycogen; moreover, at any given time muscles store glucose that is burnt for energy. When a person eats and food is digested, the pancreas is triggered to release insulin from the beta cells that is used to breakdown the glucose for the cells for energy or to be stored as fat. Any moment that the system that provides glucose to the cells breakdowns or is not regulated in an organized manner, the person is likely to develop diabetes (American Diabetes Association 2004) Type 1 Diabetes The American Diabetes ...Download file to see next pagesRead More

It takes place as a result of lack of enough insulin production in the body (Codario, 2011). Its most common symptoms include high glucose concentration, relatively deficient insulin, fatigue, blurred vision, itchiness, weight loss, frequent urination, feeling thirsty among others. The risk factors of this disease according to Hanas (2007) are; increased weight (obesity), genetics,...

In advanced stages, lifestyle and diet change plays a significant role in glycaemic control as well as reducing cardiovascular development. Exercise helps in improving metabolic control as also lead to improvement of glucose tolerance (RACGP, 2014). In terms of...

Diabetes Mellitus Type 2 diabetic. The test the level of an individual’s blood glucose level based on the ratio of glycated red blood cells. The supporting fasting blood glucose test involves checking for blood sugar levels prior to eating any meal. A level equal to or greater than mg/dL implies an individual is diabetic. The rising cases of type 2 DM around the globe have put health practitioners on an alert. The expected explosion of the number of individuals suffering from this condition thus necessitates availability of proper knowledge for evaluation, whether physical or diagnostic.

(2009) concluded that an impaired function of HMGN3 is a contributing factor in the etiology of diabetes, based on the fact that HMGN3 and the transcription factor PDX1 both bind to the chromatin in the promoter of the Glut2 gene, thereby regulating GLUT2 protein levels in pancreatic islets and in β cells. Nutrition in diabetes Historically, the hypothesis pertained to an exclusive involvement of the glucose-insulin axis in type 2 diabetes. In keeping with this view, the nutritional approaches to metabolic syndrome and...
