One of the proposed techniques for avoiding complications such as cardiovascular diseases (CVD) in patients with diabetes is to stringently control and manage blood pressure of the patient. The author believes that this practice of keeping blood pressure in check could actually be efficient in preventing CVDs. This paper aims to discuss the mechanism of diabetes mellitus, focusing on type 2. At the same time, a discussion of why strict control and management of a type 2 diabetic patient’s blood pressure could prevent CVDs will also be presented. Pertinent and related information such as prevalence of diabetes particularly in the United Kingdom will be discussed, as well as the social and economic impact of this disease.The organization of this paper begins with a brief description of diabetes mellitus, type 1 and type 2. The author deems it necessary to also present statistics such as prevalence of diabetes in the United Kingdom and CVDs. After which the author will once again emphasize on the thesis statement, followed y a presentation of supporting journals and other studies. The social and economic bearing of all these will then be expanded on, ending with the recommendations of the author, applicability of the paper to actual practice and ultimately, the conclusion.Around the world, diabetes mellitus continues to be a concern for many. In fact, over the years its prevalence has grown in several countries. According to a 2004 study by Diabetes UK (2004), since 1996 the statistics of people who have been diagnosed with diabetes went up from only 1.4 million during that year to 1.8 million. By the year 2000, they believe that diabetes will further go up to 3 million (Diabetes UK, 2004). An estimate of the International Diabetes Foundation done in 2003 was thatin 2007 the prevalence of diabetes would go up to 4% of the population (www.heartstat.org, 2008). Notably, Diabetes UK claims that most of these cases will be Type 2 because of the fast increase in the statistics of the obese and overweight individuals (Diabetes UK, 2004).
