Diabetesis a form of metabolic disease that makes the patient to have highlevels of sugar in the blood. The high amounts of glucose in bloodcan be caused by lack of sufficient insulin, as well as the body’sinability to respond to insulin. As a result of high levels of bloodsugar, patients are likely to urinate frequently, and experiencethirst most of the times. There are two types of diabetes type 1diabetes and type 2 diabetes. Type 1 diabetes is caused by thedestruction of cells that produce insulin. In addition, this form ofdiabetes can be caused by environmental factors like viruses. It canalso result from a genetic predisposition. The cause of type 2diabetes is the lack of sufficient insulin as a result of which theblood sugar level declines significantly. Moreover, this type ofdiabetes can result from the body’s inability to use the producedinsulin (American Diabetes Association, 2009).
Diabetescan also result from certain risk factors such as age, weight, andethnicity. With regard to age, people above the age of 40 years aremore likely to become diabetic than those below this age. This ismostly the case with type 1 diabetes. For type 1 diabetes, youngadults and children can be affected by this condition. Thus, a highpercentage of young people suffer from type 1 diabetes than type 2diabetes. Obesity and overweight is another risk factor that causesdiabetes thus, lack of exercise has over the years been a majorcause of diabetes. Ethnicity also plays a role in the development ofdiabetes for example, some ethnic groups such as Chinese, SouthAsian, as well as African Americans are more prone to diabeticconditions than other people (American Diabetes Association, 2009).
