Diabetes Overview and Prevention

Introduction

  • Physiology Professor quote: "If you live long enough, you're gonna get diabetes."
  • Over 530 million adults worldwide have diabetes.
  • Increase in diabetes among children and adolescents.
  • Video purpose: Understanding diabetes, its causes, prevention, and possible cures.

What is Diabetes?

  • Diabetes Mellitus: Primarily classified into type 1 and type 2 (plus gestational diabetes).
  • Discussion focus: type 1 diabetes and type 2 diabetes.
  • Key organ: Pancreas

Anatomy of the Pancreas

  • Located in the left upper abdomen, behind the stomach.
  • Structure: head, body, and tail.
  • Functions: Both an endocrine gland (secretes hormones) and exocrine gland (produces digestive enzymes).
  • Endocrine part produces insulin, which lowers blood glucose levels.

Insulin Function and Role

  • When ingesting carbohydrates:
    • Carbs break down to glucose, absorbed into the bloodstream.
    • Pancreas releases insulin, which binds to insulin receptors on the cell membranes, signaling cells to take in glucose.
    • Result: Lowered blood glucose levels.

Diabetes Types Detailed

Type 1 Diabetes (Insulin-Dependent)

  • Autoimmune destruction of beta cells in the pancreas, which produce insulin.
  • Represents 5-10% of diabetes cases, commonly in children and young teenagers.
  • Risk factors: Genetics and autoimmune response.
  • Main treatment: Insulin injection.

Type 2 Diabetes (Non-Insulin Dependent)

  • Pancreas still produces insulin, but cells become insulin-resistant.
  • Initial overproduction of insulin by the pancreas, but it wears out over time leading to high blood glucose levels.
  • Risk factors:
    • Non-modifiable: Genetics, family history, certain ethnicities.
    • Modifiable: Increased adipose (fat) tissue, poor diet, lack of exercise.
  • Management: Diet, exercise, medications like Metformin.

Role of Adipose Tissue

  • Adipocytes release adipokines, increasing insulin resistance.
  • Weight loss reduces adipose tissue and improves type 2 diabetes.

Diet and Exercise Impact

  • No single perfect diet: Healthy eating, proper vitamins, minerals, macronutrients in proper proportions.
  • Calorie deficit helps in reducing adipose tissue.
  • Exercise: Increases metabolic rate, changes carbohydrate and fat metabolism.
    • Muscle cells utilize glucose more effectively during and post-exercise, even without insulin.
    • Regular exercise increases mitochondria, improves enzyme functions, and enhances overall metabolism.

Treatment and Potential for Cure

  • Type 1 Diabetes: Mainly managed with insulin therapy.
  • Type 2 Diabetes: Diet, exercise, medications, weight loss.
    • Remission possible: Improved insulin sensitivity, withdrawal of medications.
    • Remission ≠ Cure: Risk factors can recur, leading to a return of the disease.

Conclusion

  • Health education is crucial, and lifestyle changes can drastically affect diabetes management.
  • Continuous exercise and healthy diet are key to prevention and management of type 2 diabetes.
  • Remission is possible, but vigilance is necessary to maintain health improvements.
