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 I: Introduction

Type II Diabetes I: Introduction

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 II Diabetes II: Pathophysiology

Type II Diabetes II: Pathophysiology

PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.

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...

Type I Diabetes III: Clinical Manifestations

Type I Diabetes III: Clinical Manifestations

Type 1 diabetes mellitus typically presents with rapid-onset symptoms due to the body’s inability to utilize glucose in the absence of insulin. Since insulin is required for glucose uptake into cells, its deficiency leads to hyperglycemia and cellular energy deprivation, resulting in characteristic clinical features.Polyuria and PolydipsiaOne of the earliest, most prominent symptoms is polyuria (excessive urination). When blood glucose concentrations rise above the renal threshold, the kidneys...

Pathophysiology of Diabetes

Pathophysiology 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, suggesting a...

Area of Science:

Dermatology and Endocrinology
Immunoinflammatory Diseases

Background:

Psoriasis is a chronic inflammatory skin condition affecting 2-3% globally.
An established link exists between psoriasis and an increased risk of type 2 diabetes.
The precise pathophysiological mechanisms connecting these conditions are not fully understood.

Purpose of the Study:

To review current evidence on the association between psoriasis and type 2 diabetes.
To highlight shared underlying mechanisms.
To emphasize the need for diabetes risk assessment and management in psoriasis patients.

Main Methods:

Literature review of existing studies.
Analysis of shared genetic and immunoinflammatory pathways.
Examination of diabetes risk factors prevalent in psoriasis patients.

Main Results:

Evidence suggests a multifactorial association including shared genes and inflammation.
Common risk factors contribute to the elevated diabetes risk in psoriasis patients.
The review consolidates current understanding of this comorbidity.

Conclusions:

The link between psoriasis and type 2 diabetes is supported by genetic, inflammatory, and lifestyle factors.
Proactive diabetes risk assessment, prevention, and treatment are essential for individuals with psoriasis.
Further research into shared mechanisms may reveal targeted therapeutic strategies.
