One of the most common diseases worldwide, diabetes is described as high blood sugar due to insulin resistance or lack of insulin production (“Diagnosis and Classification” , 2008). Out of 8% of the diabetic population, type II diabetes accounts for approximately 90 to 95% of the entire diabetic population (“Diagnosis and Classification,” 2008). Historically, type II diabetes was also called adult-onset diabetes or non-insulin-dependent diabetes. However, in recent times, type II diabetes is becoming more and more common among young people. Normally, insulin produced by the pancreas is transported from the bloodstream to the body's cells or stored by the liver as glycogen to balance blood sugar levels. In people with type II diabetes, blood sugar remains in the blood due to insulin resistance, leading to hyperglycemia. High cases of type II diabetes are common among people over the age of 40 (“Diagnostics of Diabete,” 2012). According to McCarthy, inactivity, decline in metabolic function and excess weight in the aging population are also linked to diabetes (2010). Although type II diabetes is accompanied by several factors, the increase in obesity is linked to the prevalence of type II diabetes (McCarthy, 2010). Women in general are more concerned about diabetes due to the increase in obesity or the fact that they might have suffered from gestational diabetes early on. According to the Center for Disease Control and Prevention, women who have suffered from gestational diabetes may have a 35 to 60 percent chance of developing type II diabetes in later years (2013). With a large number of obese women, it is essential to find preventive measures against diabetes as one of the major risks...... middle of article ......54). Sufficient evidence demonstrating that diabetes prevention with metformin outweighs the risk would support implementation of metformin without any fear of complications. It is still controversial whether a nurse advises patients on whether metformin or exercise is more effective in preventing type II diabetes. Therefore, a nurse may not be able to make an informed decision about how best to advise the patient in the treatment of diabetes. Therefore, the objective of this article is to use available research to identify the effectiveness of metformin as well as side effects and other complications as well as the effectiveness of exercise therapy in the treatment of diabetes mellitus. type II. The effectiveness of the two therapies will be determined based on the reduction of obesity in women, normal blood sugar levels, reduction of diabetes-related diseases and reduction of diabetes..
