Understanding Diabetes: Homeostasis and Its Impact

This introduction delves into the intricacies of diabetes, a disease that disrupts internal stability in the body, focusing on the role of insulin in regulating blood sugar levels. It explains how insulin deficiency or resistance leads to the inability of cells to take in glucose for energy, ultimately causing diabetes. The text covers the types of diabetes, statistics on prevalence and associated health risks, emphasizing the importance of early diagnosis and intervention. While there is no cure yet, advancements in treatments and ongoing research offer hope for managing diabetes effectively.

Presentation Transcript

  1. Introduction to Diabetes

  2. Homeostasis • Internal stability within the body • Metabolic processes occur within normal ranges Homeostasis disrupted = disease or illness Example: Diabetes

  3. What is Insulin? • Very Important Protein (hormone) • Regulates glucose entering cells • Created by the Pancreas • Controls blood sugar • Lack of insulin function = Diabetes

  4. So What? • Without insulin, cells do not take in the glucose they need for energy. • If the cell becomes resistant to insulin (type 2 diabetes) it has the same effect as if there was not insulin present; the cells do not take in glucose from the blood.

  5. Who Gets Diabetes? • 20.6 Million Americans have it! • 1 in 250 Americans Pictures from Microsoft Clip Art: http://www.microsoft.com

  6. Answer? Anyone Can!! Pictures from Microsoft Clip Art: http://www.microsoft.com

  7. Types of Diabetes • Type 1:Insulin-Deficient Diabetes old name: Juvenile Diabetes • Type 2:Insulin-Resistant Diabetes old name: Adult Onset Diabetes

  8. Did You Know…. • Worldwide: 2002 - 171,000,000 known to be diabetic 2030- 371,000,000 expected to be diabetic 2005 – 1 million people died from diabetes http://www.cdc.gov/diabetes/statistics

  9. Did You Know… • In the U.S. • 2002 – 17,702,000 known to be diabetic • 2030 – 30,317,000 expected • 1/3 of adults do not know they have it • 2002 - $132billion health care cost • 2000-2005 – age of onset getting younger http://www.cdc.gov/diabetes/statistics/

  10. Did You Know… • 50% of diabetics will have heart disease • 12% of diabetics will suffer serious vision loss early on • 75% of diabetics will suffer serious vision loss after 15 years • 1/10 of U.S. health care dollars are spent to treat diabetes http://www.cdc.gov/diabetes/statistics

  11. The Good News • Better treatments • Earlier diagnosis • Proactive early intervention techniques • New Research • But:There is no cure.Yet!

  12. Understanding Diabetes • Look at role of: • Food • Macromolecules • Metabolism • Feedback loops • Blood sugar concentration • Insulin
