Diabetes Mellitus: Type 2 and Gestational01:22

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 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.
Type II Diabetes I: Introduction01:26

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 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 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...
Pathophysiology of Diabetes01:20

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:

    • Oral Health
    • Endocrinology
    • Public Health

    Background:

    • Periodontal inflammation is linked to type 2 diabetes (T2DM) via systemic inflammation, a common feature of metabolic syndrome.
    • The relationship between periodontitis and T2DM is bidirectional, with inflammation exacerbating diabetes and diabetes increasing periodontitis prevalence and severity.
    • Weight reduction shows long-term benefits for periodontitis management.

    Purpose of the Study:

    • To investigate the correlation between periodontitis and metabolic indicators in T2DM patients.
    • To compare these correlations in a control group to assess the specific impact of T2DM.
    • To highlight the role of general practitioners in identifying at-risk individuals.

    Main Methods:

    • A study involving 50 patients with T2DM and a control group of 50 individuals.
    • Assessed the presence and severity of periodontitis.
    • Correlated periodontitis data with blood glucose, glycated hemoglobin (HbA1c), C-reactive protein (CRP), and relative body weight.

    Main Results:

    • In T2DM patients, periodontitis correlated with blood glucose, HbA1c, and CRP, but not relative body weight.
    • In the control group, periodontitis correlated with blood glucose, HbA1c, and relative body weight.
    • These findings underscore the specific link between periodontitis and T2DM-related metabolic dysregulation.

    Conclusions:

    • Periodontitis is a significant risk factor for developing T2DM and metabolic syndrome.
    • General practitioners should include periodontitis screening in medical histories.
    • Referral to dental care for periodontitis management is crucial for T2DM risk reduction and improved diabetes control.
