Diabetes mellitus is one of the non-communicable diseases that have continued to be in the forefront of public health challenges. Diabetes occurs when the body system is unable to produce sufficient insulin. Typically, insulin is a hormone secreted from the beta cell within the pancreases that regulates the blood sugar as well as assisting in conversion of glucose into energy. Diabetes occurs when there is high level of glucose in the blood, and when the body pancreas in unable to produce enough insulin.
Type 2 diabetes known as non- insulin-dependent diabetes mellitus (NIDDM) accounts for more than 90% of diabetes globally. The type 2 diabetes occurs when a body is unable to produce sufficient insulin to overcome abnormality. There are three types of diabetes:
Type 1 diabetes,
Type 2 diabetes and Gestational diabetes.
Type 1 diabetes or insulin dependent diabetes is an autoimmune system where the diseases in the body attack the insulin producing pancreases cell. People with type 1 diabetes do not have ability to produce insulin and they require lifelong insulin injection to survive. Typically, type 1 diabetes could occur at any age, however, type 1 diabetes are generally frequent among children and young adults. (Valentine, Alhawassi, Roberts, et at 2011).
On the other hand, type 2 diabetes is associated with hereditary factor or lifestyle risk factors. The life style factor leading to type 2 diabetes include insufficient physical activity, poor diet, obesity and overweight. Similar to Type 1 Diabetes, the use of insulin injection could control sugar level in the blood. However, type 2 diabetes is common among people 40 years and above, and the disease is becoming prevalent among younger age group.
Objective of this paper is to discuss the prevalence and the main cause of diabetes in Australia.
1. Outlinig the incidence / prevalence and main causes of Diabetes in Australia.
Diabetes Mellitus has been identified as one of the high prevalent of disease in Australia, and its impact could lead to morbidity and death. An estimated of 280 Australians develops diabetes per day, and the total number of 3.6 million Australia has been diagnosed of diabetes. By 2031, it is estimated that approximately 3.3 million Australian will develop diabetes. Between 2008 and 2009, the National Diabetes Register recorded approximately 9,308 new cases of type 1 diabetes among people aged between 0 and 14 and 13,756 among people aged 15 and above revealing that there is an incident of 6 new cases of diabetes per day. It is also estimated that more than 100,000 people are being diagnose of diabetes yearly. (Whiting, Guariguata, Weil, et al. 2011).
In South Australia alone, more than 600 people are diagnosed of diabetes each month. Typically, diabetes is one of the fastest growing chronic diseases in Australia, and its complication could lead to stroke, heart attack, kidney damage, and foot ulcer. However, type 2 diabetes is the most prevalent type of diabetes in Australia, and between 85 and 90% of people suffering from diabetes are with type 2 diabetes.( Minges, Zimmet, Magliano, et al. 2011).
The data presented by National Diabetes Services Scheme (2012) reveals that around 85% of registrants have type 2 diabetes while 12% have type 1 diabetes.

Type 2 (insulin)
Type 2 (non-insulin )

Typically, there is no single cause of diabetes, while some cause could be changed, other could not be changed. Hereditary through family history is one the causes of diabetes in Australia. People who are over 45 years of age and one or two of the family member has diabetes have 2 or 6 times risk of developing type 2 diabetes. The risk of diabetes increases with age. People who are over 45 years of age and overweight also face the risk of developing diabetes. However, obesity is one of the major causes of diabetes and if it is possible to eliminate obesity from the Australian population, the Australia will reduce the incidence of type 2 diabetes by 38% in men and 47.4% in women. Obesity is the major risk factor associated with type 2 diabetes. Typically, people with obese body posses the three times risk factor of developing type 2 diabetes. Increase in waist-hip ratio, and waist circumference are the powerful factors leading to the prevalence of type 2 diabetes in Australia.
Typically, the rising in the number of people with type 2 diabetes in Australia is being driven by increase in the ageing population. Reduction in physical activity, and poor diet consumed are another major causes of type 2 diabetes in Australia. People who focus on eating food with energy dense and highly saturated fatty acid could face the risk of developing type 2 diabetes.
While the number of people with type 2 diabetes is higher than people with type 1 diabetes, there are still important similarities and differences in the disease process.
Similarities and Differences between Type 1 and Type 2 Diabetes
This section discusses the similarities and differences of type 1 and type 2 diabetes. One of the similarities of type 1 and type 2 diabetes is that both are characterized by a progressive ?-cell failure. Type 1 and type 2 diabetes are similar in the sense that both are genetic disease. There are genes in human body that could pass diabetes from parent to offspring. However, in type 2 diabetes, the environmental factors such as caloric intake and obesity could interact with genetic factor to increase the risk of type 2 diabetes. More importantly, both type 1 diabetes and type 2 diabetes depend on a certain amount of insulin produced by pancreas.
Moreover, both type 1 and type 2 diabetes could be compared based on their symptoms. Type 1 diabetes is caused by high blood glucose or sugar, whereas symptom of type 2 diabetes is the response of the body to high blood sugar. Patients of type 1 and type 2 diabetes may experience similar symptoms such as weight loss, increased urination, and thirst. More importantly, both type 1 and type 2 diabetes have similar complications. Both diseases could deliver a kidney disease, which may result in kidney abnormalities, and poorly managed kidney diseases could lead to the kidney failure in type 1 and type 2 diabetes. Both type 1 and type 2 diabetes may also lead to eye complication as well as disorder in the blood vessels.
Both type 1 and type 2 diabetes also have similar treatment. The treatment of both diseases is to control amount of glucose in the body by taking an exercise and balanced diet. Typically, the patients should follow a balanced diet, which include eating more vegetable and fruits. The patients should also eat food that contains low fat and calories.
Despite the similarities between type 1 and type 2, there are still differences between the two diseases. Patients with type 1 diabetes are insulin dependent. They need to take some dose of insulin daily to survive. On the other hand, patients with type 2 diabetes are not insulin dependent. Typically, the type 1 diabetes occurs when pancreases are not able to produce the insulin needed. Type 2 diabetes occurs when pancreases are unable to produce enough insulin or insulin is not working properly. Moreover, type 1 diabetes represent 15% of the all cases of diabetes while type 2 diabetes represent 85% of all cases of diabetes in Australia. Other important differences between type 1 and type 2 diabetes lie on the diagnosis, symptoms, and management. Table 1 presents overall differences between Type 1 and Type 2 Diabetes.
Table 1: Differences between Type 1 and Type 2 Diabetes
Type 1 diabetes are insulin dependent
Type 2 diabetes are non-insulin dependent
Occurs when the pancreas are unable to produces the insulin needed,
Represents between 10 and 15% of all cases of diabetes
Type 1 diabetes is one of the most common chronic childhood diseases in Australia;
Type 1 diabetes is not caused through lifestyle factors,
It is increasing at about 3% yearly.
Type 2 diabetes occurs when the patient's pancreas is not producing enough insulin or the insulin is not working properly,
Type 2 diabetes represents between 85 and 90% of all cases of diabetes,
Risk factors include ethnic background, family history and overweight -- especially around the waist,
Lifestyle factors such as unhealthy food. Insufficient or lack of physical activity can contribute to type 2 diabetes development.
The disease can occur at any age; however, it usually occurs among younger age group.
The disease usually occur in adults who are over the age of 45, however, it is increasingly common among younger age.
The symptoms of type 1 diabetes include excessive thirst, fatigue constant, urination, weakness unexplained weight loss, and, irritability.
In type 2 diabetes, symptoms may sometimes go unnoticed as the disease develops gradually.…[continue]

The symptoms are similar but type 2 can be more insidious as it is more commonly undiagnosed and could possibly have been prevented with early intervention lifestyle changes. Pain and reduced circulation in the extremities and/or long-term vision loss can also occur in type 2 as does permanent nerve damage in the eyes and extremities. Dependency on insulin is present in type 1 while in type 2 other pharmacological
Head injury, brain surgery, and brain tumor are potential causes of Central Diabetes Insipidus. Nephrogenic Diabetes Inspidus is far les common than Central Diabetes Inspipidus and is caused by kidney defects. Kidney disease, an X chromosomal abnormality, and certain pharmaceuticals such as lithium can cause Nephrogenic Diabetes Insipidus. Stopping the intake of culprit medications can often reverse Nephrogenic Diabetes Insipidus. Symptoms of the different types of diabetes differ. Fatigue, excessive
Individuals are asked to work toward those goals and values they hold while experience their thoughts and positive feelings." (Gregg et al., 2007) ACT is stated to have "shown positive outcomes for a wide variety of conditions including for chronic medical conditions, even when presented in very brief form." (Gregg, et al., 2007) Gregg et al. additionally states: "Diabetes researchers have called for the development of interventions designed to
Diabetes Evidence-Based Practice Diabetes Diabetes is a disease which stays with the patient life-long except in some cases where the diabetes is gestational which occurs during pregnancy and often goes back to normal after the delivery. Typically there are two types of diabetes which are type 1 and type 2 diabetes but less common are gestational diabetes and other types which contain features of both type 1 and type 2 diabetes (Cowle
Type 2 diabetes, and its association with obesity, changes this relationship somewhat. Individuals with Type 2 diabetes typically have poor eating and exercise habits that contribute to the development of their disease, and these same risk factors also contribute to the risk for and progression of cardiovascular diseases and stroke (Mayo Clinic 2010; WebMD 2010). Though not necessarily directly related to diabetes their diabetes, these individuals have a much greater
There was therefore no coercion, evasion or unethical procedure in the study. The authors also make it clear that adequate information was provided to all those agreed to participate. There was obviously an open and transparent sharing of informstion about the project. After discussing the homework, the theme of the session was introduced and patients were invited to share their beliefs, emotions and experiences with regard to the theme. Subsequently,
Diabetes is a disease in which the body does not generate or properly use insulin. Insulin is a hormone produced in the body that is needed to convert sugar, starches and other food into energy needed for daily life (Wan). Prevalence Diabetes is among the five leading causes of death by diseases in most countries. However, what exactly cause diabetes is still unknown, but both genetics and environmental elements such as overweight
