2.  Objectives: ◦ Explain the different characteristics of type 1 diabetes, type 2 diabetes, and gestational diabetes. ◦ Show examples of the symptoms of diabetes. ◦ Guide the learners through the process of how each type is diagnosed.

3.  Happens in 5-10% of persons diagnosed with diabetes.  Mostly in children and adults up to 30 years of age (may occur at any age).  Requires insulin injections for survival.  Prone to Ketoacidosis (life threatening condition characterized by sweet fruity odor to the breath, dehydration, and coma).

4.  Partly genetic  Autoimmune process where body thinks the Beta cells in the pancreas (where insulin is produced) is the enemy and they self- destruct  Viral infection may be the trigger for the process to begin

5.  Frequent urination (polyurea)  Excessive Thirst (polydipsia)  Excessive hunger (polyphasia)  Rapid weight loss

6.  Happens in 90 - 95% of persons diagnosed with diabetes  Mostly in adults after 30 years of age (may occur at any age)  Can go undetected for years  Not prone to Ketoacidosis (see section on Ketoacidosis)  Signs and Symptoms often not present  Is a progressive disease

7.  Strong genetic link  Insulin resistance (more than enough insulin production; however, the insulin does not work properly at the cell wall)  Insulin resistance is caused by obesity and/or lack of exercise  Not enough insulin production

8.  Fatigue  Blurred vision  Frequent yeast infections  Occasionally frequent urination and excessive thirst

9.  Most often diagnosed between 24-28 weeks of pregnancy in 4% of pregnant women. If left untreated can result in very large baby (over 9 lbs.), infant low blood sugar at birth, and still births. Chronic maternal high blood pressure (hypertension) and an increased rate of cesarean deliveries may also occur. Blood glucose/sugar levels return to normal after delivery in 90% of cases.

10.  Hormones produced by the placenta induce an environment of stress producing an insulin resistant state in the mother (see insulin resistance under Type 2 Diabetes).

11.  Step 1: ◦ Drinking a 50-gram oral glucose solution followed by a 1-hour blood glucose test. ◦ If result is equal to or greater than 140 mg/dl, further testing required.  Step 2: ◦ drinking 100-gram oral glucose solution after an 8 hour fast ◦ blood sugar test at 1, 2, and 3 hours after ◦ positive diagnosis requires that any two of the four glucose values obtained during the test meet or exceed the following values: - Fasting - 105 mg/dl - 1-hour - 190 mg/dl - 2-hour - 165 mg/dl - 3-hour - 145 mg/dl
