Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

3.1K
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,...

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...

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 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...

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...

Carbohydrate Metabolism01:36

Carbohydrate Metabolism

13.7K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Area of Science:

  • Oral Health
  • Endocrinology
  • Immunology

Background:

  • Diabetes mellitus (DM) and periodontitis exhibit a complex, bidirectional relationship, where each condition exacerbates the other.
  • Poorly controlled diabetes significantly increases periodontitis risk, severity, and progression.
  • Periodontitis is strongly associated with poor glycemic control.

Purpose of the Study:

  • To review the complex interplay between diabetes mellitus and periodontitis.
  • To explore the shared pathophysiological mechanisms.
  • To highlight the importance of integrating periodontal care into diabetes management.

Main Methods:

  • Literature review of studies examining the relationship between DM and periodontitis.
  • Analysis of biological mechanisms linking hyperglycemia, oral dysbiosis, inflammation, and bone metabolism.
  • Examination of clinical evidence on the impact of periodontal therapy on glycemic control.

Main Results:

  • Hyperglycemia in diabetes promotes oral microbial dysbiosis, leading to inflammation and impaired immune function.
  • Diabetes alters bone metabolism, increasing osteoclastogenesis and hindering bone regeneration.
  • Periodontal therapy can reduce HbA1c levels by approximately 0.43% in diabetic individuals.
  • Periodontitis may contribute to insulin resistance and glucose intolerance through systemic inflammation and impaired nitric oxide pathways.

Conclusions:

  • The bidirectional relationship between diabetes and periodontitis necessitates integrated management strategies.
  • Periodontal care holds potential for improving glycemic control and reducing healthcare costs in diabetic populations.
  • Further research is needed to address treatment heterogeneity and elucidate novel therapeutic targets for joint health benefits.
