  1. 1. Understanding Diabetes Definition Diabetes Mellitus is a chronic disease caused by inherited and/or acquired deficiency in production of insulin by pancreas, or by ineffectiveness of the insulin produced. Such a deficiency results in increased concentrations of glucose in blood which in turn could lead to damage of many of the body’s systems, specially the blood vessels and nerves.

  2. 2. Understanding Diabetes Definition Diabetes Mellitus is a syndrome characterised by chronic hyperglycemia and disturbances of carbohydrate, fat and protein metabolism associated with absolute or relative deficiencies in insulin secretion and/ or insulin action. Copyright © Year 2005
  3. 3. Understanding Diabetes Glucose & Insulin G Glucose : This is the energy for the body. Insulin : Lets the body use glucose for energy. Copyright © Year 2005
  4. 4. Understanding Diabetes Pancreas Islets of Langherhans Insulin Copyright © Year 2005
  5. 5. Understanding Diabetes Insulin Action Food enters the digestive system and is broken down. Copyright © Year 2005
  6. 6. Understanding Diabetes Insulin Action G The body breaks down the food into basic elements, including, Glucose. Glucose is the body’s main source of energy. Copyright © Year 2005
  7. 7. Understanding Diabetes Insulin Action Glucose enters the bloodstream, and the level of glucose in the blood begins to rise. Copyright © Year 2005
  8. 8. Understanding Diabetes Insulin Action Sensing the increase in blood glucose level the pancreas releases a hormone called INSULIN. Insulin helps the glucose to enter the cells. Copyright © Year 2005
  9. 9. Understanding Diabetes Insulin Action Insulin acts as a key Copyright © Year 2005
  10. 10. Understanding Diabetes Insulin Action Insulin fits into the special receptors on the cells, causing the tiny channels to open. Copyright © Year 2005
  11. 11. Understanding Diabetes Insulin Action This enables the glucose to enter the cells. Copyright © Year 2005
  12. 12. Understanding Diabetes Insulin Action In the absence of insulin or due to inefficiency of the insulin produced, the body is unable to utilize the glucose. The glucose level in the blood rises abnormally leading to Hyperglycemia. Copyright © Year 2005
  13. 13. Understanding Diabetes Signs & Symptoms D iuretic symptoms – the frequent urge to urinate I ncreased infections A bnormal weight loss B lurred vision E xcessive thirst T ingling or numbness of the feet or hands E xtreme hunger S low-to-heal wounds Copyright © Year 2005

  15. 15. Classification of Diabetes Type 1 In the absence of insulin the glucose can not enter the cells and begins to build up in the blood leading to Hyperglycemia. Copyright © Year 2005
  16. 16. Classification of Diabetes Type 1 - Causes Results from a cellular-mediated autoimmune destruction of the -cells of the pancreas. Copyright © Year 2005
  17. 17. Classification of Diabetes Type 1 - Management  Insulin  Diet  Exercise Copyright © Year 2005
  18. 18. Classification of Diabetes Type 2 Insulin resistance does not allow the cells to open its channels to glucose, hence the glucose cannot enter the cells. Copyright © Year 2005
  19. 19. Classification of Diabetes Type 2 Over a period of time the pancreas produces less insulin leading to insulin deficiency. Copyright © Year 2005
  20. 20. Classification of Diabetes Type 2 - Causes  Hereditary  Obesity  Lifestyle changes Copyright © Year 2005
  21. 21. Classification of Diabetes Type 2 - Management  Diet  Exercise  Oral Hypoglycemic Agents  Combination Therapy Copyright © Year 2005
  22. 22. Classification of Diabetes Difference Between Type 1 & Type 2 Type-1 Type-2 X Absolute deficiency of Insulin Copyright © Year 2005 Relative deficiency of Insulin X Insulin resistance
  23. 23. Classification of Diabetes Gestational Diabetes • Gestational Diabetes is a type of diabetes that occurs only in pregnancy and usually disappears after the birth of the baby. • Present in less than 15% of all pregnancies. • Usually detected at 24-28 weeks of pregnancy.
