6 Symptoms The three P’s: polyuria, polydipsia, polyphagia Weight loss (Type I), fatigue, blurred vision, coma (diabetic shock), poor circulation, renal failure Recent-onset of polyuria and polydipsia, along with weight loss

17 Type I Diabetes (cont’d) Treatment: Insulin injections, blood glucose level monitoring AWARENESS AND EDUCATION ARE CRUCIAL No cure, but lifestyle adjustments crucial

18 Type II Diabetes Resistance to insulin as well as decreased production Linkage to several physiological factors Treatment varies depending on severity

19 Gestational Diabetes Similar to Type II in resemblance 2-5% frequency Dangerous if untreated, especially for baby Shoulder distosia, induced labor common

20 Can We Find a Cure? Only “cure” for Type I- after transplant Stem cells, transplant of beta cells Gastric bypass surgery
