Dissertation on Diabetes for BSC Nursing



             Diabetes Mellitus was described first as a component of metabolic syndrome in 1988 (Guthrie & Guthrie, 2009). Levene & Donnelly (2011, p.8) defined diabetes mellitus as "a group of metabolic diseases characterized and diagnosed by a chronic elevation of blood glucose (hyperglycemia) that results from defects in insulin secretion, insulin action or both". T2DM is known to occur in susceptible adults of 25 years to 45 years and above, across different races and economic class (Weir et al., 2013). Recently obesity has being identified as a strong component of the factors that increase the risk of developing T2DM globally (Stern & Kazaks, 2009, and Barnett & Kumar, 2009) However, in the recent years, children and adolescents are been diagnosed with T2DM, this is suggested to be as a result of an increase in children obesity (Serrano Rios & Gutierrez Fuentes, 2010). Obesity is a serious health challenge globally (Day, 2014). In the UK the incidence of obesity has been estimated to increase to 50% of the population by 2050 (NHS, 2014).
             Abnormalities; B-cell dysfunction and insulin resistance (poretsky, 2010). The chronic hyperglycemia causes symptoms like polyuria, polydipsia, polyphagia, weight loss, impaired growth and increased susceptibility to infections. If not managed T2DM can lead to two groups of complications: acute (hyperglycemia hyperosmolar non-ketotic syndrome) and long-term (retinopathy, nephropathy, peripheral neuropathy, cardiovascular and sexual dysfunction) (Chandalia & Das, 2012). However, Poretsky (2010) suggested that since the condition cannot be cured, that prevention of its occurrence would be more cost-effective. Moreover, since the condition is associated with overweight, the increase in physical activity and dietary modification will be efficient in its prevention. This is discussed more in the following chapters of this report. The criteria for T2DM diagnosis is based on blood glucose level, that is when blood sugar is greater or equal to 126mg/dl during fasting (Eight hours of no calorie intake) or greater and equal to 200mg/dl casually (at any time of the day) (Serrano Rios & Gutierrez Fuentes, 2010).
