Diabetes Mellitus: Type 2 and Gestational

Diabetes Mellitus: Type 2 and Gestational

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...

Diabetes Mellitus: Introduction

Diabetes Mellitus: Introduction

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 long-term...

Diabetes Mellitus: Overview and Type I Subtype

Diabetes Mellitus: Overview and Type I Subtype

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Type I Diabetes II: Pathophysiology

Type I Diabetes II: Pathophysiology

Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...

Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis

Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis

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 hypertension...

Psychoneuroimmunology: Diabetes and Cancer

Psychoneuroimmunology: Diabetes and Cancer

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Area of Science:

Nutritional Biochemistry
Metabolic Diseases
Oxidative Stress

Background:

Diabetes mellitus is a prevalent metabolic disease linked to overnutrition and obesity.
Untreated diabetes causes oxidative stress, leading to secondary complications.
Antioxidant supplements were previously considered beneficial for diabetes therapy.

Purpose of the Study:

To review current human and animal studies on selenium's role in diabetes.
To explore the dual effects of selenium on diabetes development and progression.
To clarify the inconsistent findings regarding selenium and diabetes incidence.

Main Methods:

Systematic review of human and animal studies.
Analysis of cross-sectional and interventional trials.
Discussion of potential mechanisms of selenium's influence on diabetes.

Main Results:

High selenium status shows a positive correlation with diabetes incidence in humans.
Selenium supplements are not recommended for diabetes prevention in high-Se populations (except pregnant women).
Apparent anti-diabetic effects of selenium require high, potentially toxic doses unsuitable for human use.

Conclusions:

The relationship between selenium and diabetes is complex and currently enigmatic.
Future research should investigate selenium's role considering the specific stage of diabetes.
Current evidence does not support selenium supplementation for diabetes prevention or treatment in most populations.
