Flashcards
Type 1 Diabetes
Type 1 Diabetes
A condition characterized by loss of functioning beta cells in the pancreas, leading to absolute insulin deficiency.
Type 2 Diabetes
Type 2 Diabetes
A condition characterized by insulin resistance, where the body either doesn't produce enough insulin or cannot use it properly.
Insulin Resistance
Insulin Resistance
The process by which the body's cells become less responsive to insulin, hindering the uptake of glucose.
Ketoacidosis
Ketoacidosis

Study Notes
Diabetes Mellitus Type 1
- Aetiology: Destruction of beta cells in the pancreas
- Insulin necessity: Always
- Age: Under 30 years old
- Obesity Association: No
- Genetic Predisposition: Weak
- HLA System Risk: HLA-DR3 and HLA-DR4, severe
- Glucose Intolerance: Not applicable
- Insulin Sensitivity: High
- Ketoacidosis: Common
- Number of Beta Cells: Decreased
