This paper provides an overview of the major forms of diabetes, distinguishing between Diabetes Mellitus and Diabetes Insipidus. It examines the causes and risk factors of Type 1 and Type 2 Diabetes Mellitus, including insulin dysfunction, heredity, and lifestyle factors, as well as the two subtypes of Diabetes Insipidus — Central and Nephrogenic — and their respective etiologies involving antidiuretic hormone deficiency and kidney defects. The paper also compares shared and distinct symptoms across all forms of the disease and summarizes available treatment approaches, noting that while Diabetes Mellitus is chronic and incurable, Diabetes Insipidus carries a more positive prognosis.
The paper demonstrates effective use of classification as an organizational strategy. By first establishing the taxonomy of diabetes types and then systematically addressing each category across multiple dimensions (causes, risk factors, symptoms, treatment), the writer ensures parallel coverage of all subjects without repetition or confusion.
The paper opens with a classification of diabetes types and their prevalence, then separates into cause-focused paragraphs for Diabetes Mellitus and Diabetes Insipidus. A dedicated symptoms paragraph draws cross-type comparisons before a final section addresses treatment and prognosis. This five-part structure — classification, Mellitus etiology, Insipidus etiology, symptoms, and treatment — is compact and well-suited to an introductory health science overview.
Diabetes Mellitus and Diabetes Insipidus are the major forms of diabetes. Diabetes Mellitus is further divided into Type 1 and Type 2. Diabetes Insipidus is subdivided into Central and Nephrogenic Diabetes Insipidus, though the former is far more prevalent. The most common form of diabetes overall is Type 2 Diabetes Mellitus, which affects at least 15 million Americans (Mathur).
Although Type 1 and Type 2 Diabetes Mellitus share certain symptoms and prognoses, their etiologies are unrelated. Diabetes Mellitus and Diabetes Insipidus are completely distinct conditions: Diabetes Insipidus is a kidney-related illness, whereas Diabetes Mellitus is related to blood sugar levels. Type 2 Diabetes Mellitus is also referred to as adult-onset diabetes because it is commonly diagnosed in patients over 45 years of age. Of all types of diabetes, Type 2 Mellitus is the one most likely to be caused by lifestyle choices.
Both Type 1 and Type 2 Diabetes Mellitus are caused by the body's inability to metabolize insulin, a chemical produced in the pancreas. Patients may be unable to secrete or use insulin effectively, which leads to excessive levels of glucose in the blood. Type 1 Diabetes Mellitus is almost always caused by the pancreas not producing enough insulin, and patients must administer daily insulin injections to survive.
Persons at risk for developing Type 2 Diabetes Mellitus may be overweight or have high blood pressure, high blood cholesterol, or high levels of blood triglycerides. Heredity may also be a risk factor for Type 2 diabetes. Some ethnic groups, including African Americans and Hispanics, demonstrate a higher risk for developing the illness. Type 1 Diabetes Mellitus is generally diagnosed in childhood and may therefore be related to hereditary factors. Unlike Type 2 diabetes, Type 1 diabetes is not preventable through diet and exercise.
Diabetes Insipidus can also be hereditary but is most commonly caused by injuries to the hypothalamus. Central Diabetes Insipidus is caused directly by a lack of antidiuretic hormone (ADH), which is produced in the hypothalamus and stored and released by the pituitary gland (Medline). Head injury, brain surgery, and brain tumors are potential causes of Central Diabetes Insipidus.
Nephrogenic Diabetes Insipidus is far less common than Central Diabetes Insipidus 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 the condition.
