Diabetes (Terms)
• Diabetes mellitus – (DM) A chronic disease characterized by an altered relationship between sugar (glucose) and insulin.
![Page 3: Diabetes For EMS Providers](https://reader033.vdocument.in/reader033/viewer/2022061116/5465e0e3b4af9fcc138b4a69/html5/thumbnails/3.jpg)
Diabetes
• Insulin – A hormone secreted by the pancreas that is needed to promote the movement of glucose (sugar) from the blood into the cells.
• Glucose – A simple form of sugar, the body’s main source of energy.
![Page 4: Diabetes For EMS Providers](https://reader033.vdocument.in/reader033/viewer/2022061116/5465e0e3b4af9fcc138b4a69/html5/thumbnails/4.jpg)
Diabetes
• Type I (IDDM)- Insulin dependent diabetes mellitus, usually acquired in childhood, produce no insulin (inheritable, auto-immune)– Requires insulin administration
![Page 5: Diabetes For EMS Providers](https://reader033.vdocument.in/reader033/viewer/2022061116/5465e0e3b4af9fcc138b4a69/html5/thumbnails/5.jpg)
Diabetes
• Type II (NIDDM) – Non-insulin dependent diabetes mellitus, usually acquired in adulthood (related to overweight), produce some insulin – not enough, or tissue sensitivity diminished– Can be controlled by diet, exercise, oral meds
![Page 6: Diabetes For EMS Providers](https://reader033.vdocument.in/reader033/viewer/2022061116/5465e0e3b4af9fcc138b4a69/html5/thumbnails/6.jpg)
Role of the Pancreas
• Primary role is the regulation of blood glucose concentrations.
![Page 7: Diabetes For EMS Providers](https://reader033.vdocument.in/reader033/viewer/2022061116/5465e0e3b4af9fcc138b4a69/html5/thumbnails/7.jpg)
DiabetesRole of the Pancreas
• Islets of Langerhans produce insulin– Alpha cells – Glucagon– Beta cells – Insulin– Delta cells – Somatostatin (inhibits the
secretaries of growth hormone)
![Page 8: Diabetes For EMS Providers](https://reader033.vdocument.in/reader033/viewer/2022061116/5465e0e3b4af9fcc138b4a69/html5/thumbnails/8.jpg)
Islets of Langerhans
![Page 9: Diabetes For EMS Providers](https://reader033.vdocument.in/reader033/viewer/2022061116/5465e0e3b4af9fcc138b4a69/html5/thumbnails/9.jpg)
DiabetesBeta Cells
• Insulin– Increase glucose transport into the cell– Increase liver glycogen levels (storage)– Decrease blood glucose concentration– Glucagon Antagonist
![Page 10: Diabetes For EMS Providers](https://reader033.vdocument.in/reader033/viewer/2022061116/5465e0e3b4af9fcc138b4a69/html5/thumbnails/10.jpg)
DiabetesAlpha Cells
• Glucagon –– Released when blood sugar levels drop– Increase blood glucose levels– Breaks down fats and fatty acids (storage
removal)– Insulin Antagonist
![Page 11: Diabetes For EMS Providers](https://reader033.vdocument.in/reader033/viewer/2022061116/5465e0e3b4af9fcc138b4a69/html5/thumbnails/11.jpg)
High/Low Blood Sugar
![Page 12: Diabetes For EMS Providers](https://reader033.vdocument.in/reader033/viewer/2022061116/5465e0e3b4af9fcc138b4a69/html5/thumbnails/12.jpg)
DiabetesGlucagon
• Triggered by exercise, stress, sleep, hypoglycemia
• Insulin antagonist (decreases insulin’s actions)
![Page 13: Diabetes For EMS Providers](https://reader033.vdocument.in/reader033/viewer/2022061116/5465e0e3b4af9fcc138b4a69/html5/thumbnails/13.jpg)
DiabetesLong Term Effects
• Blindness• Kidney disease• Peripheral neuropathy• Heart disease and stroke
(atherosclerosis)– HD: 2X - 4X non-diabetic– S: 2X - 6X non-diabetic
• Limb amputations

Diabetes• Hyperglycemia – Lack of insulin, glucose
cannot enter the cells. Remains in the blood stream increases the level of blood sugar.
• Hypoglycemia (Insulin Shock) – Lack of glucose in the blood stream, cells deprived of glucose.
• Normal sugar level – 80-120 mg/dL
![Page 15: Diabetes For EMS Providers](https://reader033.vdocument.in/reader033/viewer/2022061116/5465e0e3b4af9fcc138b4a69/html5/thumbnails/15.jpg)
DiabetesOnset
• Type I – May occur at birth, usually occurs in teenage or young adult years– Typically a sudden onset of – Polyuria (excessive urination), – Polydipsia (excessive thirst), – Polyphagia (excessive ingestion of food), dizziness,
blurred vision, rapid and unexplained weight loss.
![Page 16: Diabetes For EMS Providers](https://reader033.vdocument.in/reader033/viewer/2022061116/5465e0e3b4af9fcc138b4a69/html5/thumbnails/16.jpg)
