Diabetes: Diagnosis, Symptoms, and Epidemiology
This paper provides a comprehensive overview of diabetes mellitus as a chronic public health disease affecting millions of Americans and hundreds of millions of people worldwide. It describes the clinical diagnostic criteria — including fasting plasma glucose, oral glucose tolerance, and random plasma glucose tests — and distinguishes between Type 1 and Type 2 diabetes. The paper outlines common symptoms such as increased thirst, frequent urination, and fatigue, and reviews the descriptive epidemiology of the disease, including its rising prevalence, racial and ethnic disparities in incidence, and key risk factors such as obesity and physical inactivity. The paper concludes by framing diabetes as both a local and global public health emergency.

What makes this paper effective
- The paper follows a clear organizational logic, moving from clinical definitions and diagnostic criteria to symptoms and then to population-level epidemiology, making it easy to follow for general and academic audiences alike.
- It grounds every major claim in a specific citation, using a mix of CDC data, WHO estimates, and peer-reviewed journal sources to balance authoritative public health statistics with academic evidence.
- The epidemiology section is notably data-rich, presenting prevalence rates broken down by race, ethnicity, and time period, which adds analytical depth beyond a simple disease description.
Key academic technique demonstrated
The paper effectively uses descriptive epidemiology to contextualize a clinical topic. Rather than limiting the discussion to how diabetes works in an individual body, the author situates the disease within population trends, demographic disparities, and economic costs — demonstrating how public health frameworks add meaning to clinical data.
Structure breakdown
The paper opens with a general introduction to diabetes and its prevalence, then moves into a dedicated section on diagnostic criteria (covering OGTT, FPG, and random plasma glucose tests), followed by a symptom overview. The bulk of the paper is the descriptive epidemiology section, which covers U.S. prevalence by race and ethnicity, trends over time, and risk factors. A brief global burden section precedes the conclusion, which summarizes key points and reinforces the public health urgency of the disease.
Introduction
Diabetes is a disease that affects the way the body uses blood sugar. It is, moreover, a chronic health condition that — with health screenings, medication, diet, and exercise — can be controlled. The lack of education about the disease and appropriate healthcare for it results in a lower quality of life or premature death. According to the CDC (2022), approximately 122 million Americans are living with diabetes.
Normally, the body breaks down food into glucose, which is then used for energy. However, in people with diabetes, the body either does not produce enough insulin — a hormone that helps regulate blood sugar — or it cannot use insulin effectively. As a result, glucose builds up in the blood instead of being used for energy. Over time, this can lead to serious health problems such as heart disease, stroke, and kidney disease. Diabetes is a major public health problem in the United States and globally (Al-Lawati, 2017). About 9% of Americans have diabetes, and approximately one-third of those who have it do not even know it (CDC, 2022). The good news is that diabetes can be controlled through diet, exercise, and medication. By taking steps to control diabetes, people can reduce their risk of developing serious complications. This paper describes the diagnostic criteria and symptoms of diabetes, the epidemiology of the disease, and who is most impacted.
