Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

4.3K
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...

Carbohydrate Metabolism01:36

Carbohydrate Metabolism

13.8K
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...

Diabetes: Symptoms, Diagnosis, and Complications

2.1K
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...

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,...

Diabetes Mellitus: Overview and Type I Subtype

4.9K
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...

Diabetes: Management and Pharmacotherapy

867
The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.
Insulin remains the cornerstone of treatment for most patients with type 1 and many...

Area of Science:

  • Endocrinology
  • Public Health
  • Medical Education

Background:

  • Diabetes mellitus is a chronic condition requiring ongoing management to prevent complications.
  • Widespread misconceptions regarding diabetes pathogenesis, nutrition, lifestyle, management, and stigma hinder effective treatment.
  • Patient understanding is crucial for successful diabetes mellitus self-management.

Purpose of the Study:

  • To evaluate patient misconceptions about the causes and management of diabetes mellitus.
  • To explore the prevalence of these misconceptions in relation to demographic factors like age and gender.

Main Methods:

  • A cross-sectional study involving 390 individuals with type 2 diabetes mellitus in Isfahan, Iran (2021-2022).
  • Data collection via questionnaire on diabetes causes, diet, treatment, and complications.
  • Statistical analysis using the chi-squared test (SPSS v.16).

Main Results:

  • Prevalent myths include: solid oils are solely fattening (77.4%), unlimited dried mulberry consumption is permissible (51.5%), diabetes is purely hereditary (45.3%), only obesity causes diabetes (42.8%), and unlimited fruit intake is safe (36.6%).
  • The study included 58% females with a mean age of 56 ± 13.4 years.

Conclusions:

  • Diverse patient misunderstandings regarding diabetes mellitus etiology and management persist.
  • Myths negatively impact glycemic control, underscoring the critical role of patient education in diabetes care.
