Flashcards

Diabetes

A chronic condition with high blood sugar levels, caused by either insufficient insulin production or ineffective insulin use.

Type 1 Diabetes

An autoimmune disease where the body's immune system attacks the insulin-producing cells in the pancreas.

Type 2 Diabetes

A condition involving insulin resistance and impaired insulin secretion, often linked to lifestyle factors.

Insulin Resistance

A condition where the body's cells don't respond effectively to insulin.

Study Notes

Diabetes

  • Diabetes is a chronic condition with high blood sugar levels.
  • Characterized by the body not producing enough insulin or not using insulin effectively.
  • Two main types: Type 1 and Type 2.

Type 1 Diabetes

  • Autoimmune condition.
  • Body mistakenly attacks insulin-producing cells in the pancreas.
  • Usually diagnosed in children and young adults.
  • Requires insulin therapy to manage blood sugar.

Type 2 Diabetes

  • More common.
  • Often associated with lifestyle factors.
  • Body becomes resistant to insulin or doesn't produce enough.
  • Typically develops in adults but increasingly seen in children.
  • Management includes lifestyle changes, medications, and sometimes insulin therapy.

Mechanisms of Diabetes

Type 1 Diabetes

  • Autoimmune Reaction: Immune system attacks and destroys insulin-producing beta cells in the pancreas.
  • Insulin Deficiency: Insulin production decreases dramatically due to beta cell destruction. High blood sugar levels result.

Type 2 Diabetes

  • Insulin Resistance: Body cells become less responsive to insulin, hindering glucose uptake.
  • Impaired Insulin Secretion: Over time, the pancreas may not produce enough insulin to overcome the resistance.
  • Increased Gluconeogenesis: Liver produces excess glucose, further contributing to high blood sugar.

Treatment for Diabetes

Type 1 Diabetes

  • Insulin Therapy (injections or pump)
  • Monitoring Blood Sugar
  • Dietary Management (focus on carbohydrate counting)
  • Physical Activity (improves insulin sensitivity and overall health)

Type 2 Diabetes

  • Lifestyle Changes (diet and exercise)
  • Oral Medications
