2 Diabetes- What is it? Body is not producing or has lost sensitivity to insulin.Body is not producing or has lost sensitivity to insulin. Insulin is a hormone that is needed to convert sugar, starches and other food into energy.Insulin is a hormone that is needed to convert sugar, starches and other food into energy. Insulin is produced in the body by the pancreas.Insulin is produced in the body by the pancreas.

3 Types of Diabetes There are several types of diabetes: Type I - body does not produce any insulin.Type I - body does not produce any insulin. Type II- body is not making enough or is losing sensitivity to insulin made.Type II- body is not making enough or is losing sensitivity to insulin made.

4 Types of Diabetes Secondary - a consequence from another disease. For example, pancreatitis or cystic fibrosis.Secondary - a consequence from another disease. For example, pancreatitis or cystic fibrosis. Gestational Diabetes- diabetes during pregnancy.Gestational Diabetes- diabetes during pregnancy. Impaired Glucose Tolerance- an intermediate between normal and diabetes.Impaired Glucose Tolerance- an intermediate between normal and diabetes.

5 Quick Review-Anatomy of the Pancreas A gland that lies behind the stomachA gland that lies behind the stomach Clusters of cells inside the pancreas known as the islets of Langerhans produces three hormones.Clusters of cells inside the pancreas known as the islets of Langerhans produces three hormones. The islets contain 3 types of cells:The islets contain 3 types of cells: Alpha, beta, and delta.Alpha, beta, and delta. Alpha cells produce glucagon.Alpha cells produce glucagon.

6 Pancreas contd. Beta cells- produce insulinBeta cells- produce insulin Delta cells- produce somatostatinDelta cells- produce somatostatin These cells have special sensors that monitor levels of blood sugar and stimulate the release of the correct hormone.These cells have special sensors that monitor levels of blood sugar and stimulate the release of the correct hormone.

7 Insulin and the other hormones Glucagon - Hormone that increases the amount of glucose in the blood when it is needed.Glucagon - Hormone that increases the amount of glucose in the blood when it is needed. Somatostatin - Hormone that can suppress both glucagon and insulin when needed.Somatostatin - Hormone that can suppress both glucagon and insulin when needed. Insulin- Hormone that lowers blood glucose.Insulin- Hormone that lowers blood glucose.

8 How Does Insulin Work? A person normally secretes insulin in response to an elevated blood sugar level.A person normally secretes insulin in response to an elevated blood sugar level. It does this by accelerating blood sugars movement out of the blood and into the cells.It does this by accelerating blood sugars movement out of the blood and into the cells. Cells will not allow blood sugar in without insulin. - this can cause a problem.Cells will not allow blood sugar in without insulin. - this can cause a problem.

9 Why isnt the body making insulin? In people with Type I, the immune system has made a big mistake!In people with Type I, the immune system has made a big mistake! It attacks the beta cells and destroys them!It attacks the beta cells and destroys them! In people with Type II, the pancreas is still making insulin, just not enough to keep up, or their bodies have become insulin resistant!In people with Type II, the pancreas is still making insulin, just not enough to keep up, or their bodies have become insulin resistant!

10 Type I Usually diagnosed in children and young adults.Usually diagnosed in children and young adults. Must take daily insulin shots to stay alive.Must take daily insulin shots to stay alive.

11 Type II The most common form of the disease.The most common form of the disease. Approximately 50% of men and 70% of women are obese at the time of diagnosis.Approximately 50% of men and 70% of women are obese at the time of diagnosis.

12 Gestational Diabetes Pregnant women have a higher insulin level.Pregnant women have a higher insulin level. If woman has hyperglycemia, her blood glucose crosses the placenta but her insulin does not.If woman has hyperglycemia, her blood glucose crosses the placenta but her insulin does not.

14 How are you diagnosed with diabetes? In June 1997, the ADA redefined its criteria for diagnosing diabetes.In June 1997, the ADA redefined its criteria for diagnosing diabetes. Normal fasting blood glucose is <110 mg/dl.Normal fasting blood glucose is <110 mg/dl. Impaired fasting glucose is >110 and 110 and <126 mg/dl. Provisional diagnosis for diabetes>126 mg/dlProvisional diagnosis for diabetes>126 mg/dl

15 Diagnosis contd. In order to be diagnosed with diabetes:In order to be diagnosed with diabetes: Person must have symptoms of diabetes +Person must have symptoms of diabetes + Causal plasma glucose >200Causal plasma glucose >200 Fasting blood glucose of >126 mg/dlFasting blood glucose of >126 mg/dl 2-hour plasma glucose >200 mg/dl on oral glucose test2-hour plasma glucose >200 mg/dl on oral glucose test

16 Whos at risk? ADA now recommends that screening for diabetes should be considered for all patients at age 45. If the results are normal it should be repeated every 3 years. Screening should be considered at a younger age if patient meets following risk factors:

17 Whos at risk? ObesityObesity First degree relative with diabetesFirst degree relative with diabetes Belongs to a high-risk ethnic groupBelongs to a high-risk ethnic group Was diagnosed with gestational diabetes or delivered a baby whose birth weight >9 lbs.Was diagnosed with gestational diabetes or delivered a baby whose birth weight >9 lbs.

19 Ive got Diabetes, now what? After diagnosis, there is a great need for education.After diagnosis, there is a great need for education.

41 Hyperglycemia Ketoacidosis: Develops when the body does not have enough insulin. The body cant break down sugar so it breaks down fat instead. Ketones are what is left from this process.The body does not tolerate ketones and tries to pass them out of the body.

42 Hyperglycemia Symptoms that may result in ketoacidosis occur when: Too little insulin has been ejected, or insulin is not effective.Too little insulin has been ejected, or insulin is not effective. Consumed more food and/or exercised less than expected.Consumed more food and/or exercised less than expected. High blood sugar, high levels of sugar in the urine, frequent urination, and increased thirstHigh blood sugar, high levels of sugar in the urine, frequent urination, and increased thirst

43 How to treat Hyperglycemia Usually can lower it by exercising, or injecting more insulin, be careful of the somogyi effect.Usually can lower it by exercising, or injecting more insulin, be careful of the somogyi effect. The somogyi effect is the condition of hypoglycemia resulting from the treatment of hyperglycemia.
