Summary
Diabetes prevalence is increasing globally, affecting millions and leading to severe health complications. Urgent public health strategies are needed to address this growing diabetes burden and its associated risks.
Area of Science:
- Endocrinology
- Public Health
- Epidemiology
Background:
- Diabetes mellitus represents a significant and escalating global health challenge.
- Rising obesity and lifestyle factors are driving the increasing prevalence of diabetes worldwide.
- Current estimates indicate 382 million people had diabetes in 2013, projected to reach 592 million by 2035.
Conclusions:
- Diabetes is a critical public health issue demanding global attention and intervention.
- Effective management and prevention strategies are essential to mitigate its widespread impact.
- Addressing obesity and unhealthy lifestyles is crucial to curb the rising tide of diabetes.

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...

Type 2 diabetes mellitus develops gradually and is often asymptomatic in early stages.Clinical ManifestationsWhen symptoms appear, they include fatigue, blurred vision, pruritus, delayed wound healing, and recurrent infections, particularly candidal infections. Peripheral neuropathy may present as numbness or tingling in the extremities. Classic hyperglycemia symptoms—polyuria, polydipsia, and polyphagia—are less common. Most patients are overweight and frequently have associated...

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

2
Diabetes mellitus consists of chronic metabolic disorders characterized by persistent hyperglycemia. This elevated blood glucose results from defects in insulin secretion, impaired insulin action, or both. Insulin, produced by pancreatic β-cells, is essential for maintaining glucose homeostasis by facilitating cellular glucose uptake for energy or storage. Disruptions in insulin production or function lead to glucose accumulation in the bloodstream, causing the clinical features and...
