2
What Is Type 2 Diabetes?
• High fasting blood sugar levels
• Excessively high non-fasting BS
levels
People with Type-2 diabetes usually have some degree of both:
• resistance to the action of insulin • decrease in the capacity to produce insulin

4
What Are the Symptoms?• Increased thirst• Increased urination• Blurred vision• Lack of energy• More frequent infections, especially gum
disease and bladder infections
Symptoms come on gradually and are often viewed as a normal part of the aging process

Type 2 Diabetes

What Are the Risk Factors?
• Increasing age• Family history of type 2 diabetes• Prior history of gestational diabetes,
impaired glucose tolerance, and/or insulin resistance
Being overweight or obesePhysical inactivityConsumption of a high fat,
high sugar, refined carbohydrate diet
Risk factors you can control
![Page 9: 1 Type 2 Diabetes – An Overview What is it? Is it common? What are the risk factors? How does it start? What is the best diet?](https://reader033.vdocuments.net/reader033/viewer/2022061304/5513bb8a5503464b298b470d/html5/thumbnails/9.jpg)
The Progression of Type 2 Diabetes
Some people who have insulin resistance or impaired glucose tolerance die of cardiovascular disease before reaching type 2 diabetes.
1. Insulin resistance
2. Impaired glucose tolerance
3. Type 2 diabetes
Cancer, heart
disease

10
Insulin Resistance
• Resistance to the blood sugar lowering action of insulin
• Present for many years before fasting blood sugar levels rise above normal
Not everyone who has insulin resistance will develop diabetes but everyone with type 2 diabetes has insulin resistance
![Page 11: 1 Type 2 Diabetes – An Overview What is it? Is it common? What are the risk factors? How does it start? What is the best diet?](https://reader033.vdocuments.net/reader033/viewer/2022061304/5513bb8a5503464b298b470d/html5/thumbnails/11.jpg)
11
Insulin Resistance
• A risk factor for the development of coronary artery disease and type 2 diabetes
• Fasting insulin levels are often elevated
Currently there is no cost effective, easy way to detect insulin resistance
![Page 12: 1 Type 2 Diabetes – An Overview What is it? Is it common? What are the risk factors? How does it start? What is the best diet?](https://reader033.vdocuments.net/reader033/viewer/2022061304/5513bb8a5503464b298b470d/html5/thumbnails/12.jpg)
12
Insulin Resistance• Family history of diabetes• Overweight• Lack of Physical Activity• Cardiovascular disease in family• High triglycerides and low HDL (good
cholesterol)• High waist to hip ratio
These are all suggestive of the presence of insulin resistance
![Page 13: 1 Type 2 Diabetes – An Overview What is it? Is it common? What are the risk factors? How does it start? What is the best diet?](https://reader033.vdocuments.net/reader033/viewer/2022061304/5513bb8a5503464b298b470d/html5/thumbnails/13.jpg)
13
Heart Disease & Type 2 Diabetes
• Even if fasting blood sugar is in normal range, risk of heart disease is elevated if insulin resistance syndrome is present
![Page 14: 1 Type 2 Diabetes – An Overview What is it? Is it common? What are the risk factors? How does it start? What is the best diet?](https://reader033.vdocuments.net/reader033/viewer/2022061304/5513bb8a5503464b298b470d/html5/thumbnails/14.jpg)
14
What Is the Best Way to Reduce Insulin Resistance
• Exercise regularly• Lose excess body fat • Eat a high-fiber,
whole food diet that is low in fat, sugar and refined carbohydrates
![Page 15: 1 Type 2 Diabetes – An Overview What is it? Is it common? What are the risk factors? How does it start? What is the best diet?](https://reader033.vdocuments.net/reader033/viewer/2022061304/5513bb8a5503464b298b470d/html5/thumbnails/15.jpg)
15
Impaired Glucose Tolerance
• A pre-diabetic state
• A large percentage will progress to type 2 diabetes with time
• Occurs in about 20 million Americans
![Page 16: 1 Type 2 Diabetes – An Overview What is it? Is it common? What are the risk factors? How does it start? What is the best diet?](https://reader033.vdocuments.net/reader033/viewer/2022061304/5513bb8a5503464b298b470d/html5/thumbnails/16.jpg)
16
Impaired Glucose Tolerance
• Often present when fasting blood sugar is between 110-125 mg/dl
• Usually not associated with any symptoms
• Usually associated with an increased waist to hip ratio
• Often associated with a family history of type 2 diabetes
![Page 17: 1 Type 2 Diabetes – An Overview What is it? Is it common? What are the risk factors? How does it start? What is the best diet?](https://reader033.vdocuments.net/reader033/viewer/2022061304/5513bb8a5503464b298b470d/html5/thumbnails/17.jpg)
17
Impaired Glucose Tolerance
• Associated with an increased risk of cardiovascular disease
• Increased blood clots• Insulin resistance is present
• Dyslipidemia is frequently present–Low HDL –High triglycerides–Small dense LDL particles

18
What Is the Best Way to Reduce or Reverse Impaired
Glucose Tolerance?• Exercise regularly• Lose excess body fat • Eat a high-fiber, whole food diet that is low

Complications of Diabetes• Damage to small blood vessels and
peripheral nerves• Risk of dying of a heart attack is 2-3 times
greater• Number one cause of kidney failure in US
• Nerve damage• Damage to retina• Number one cause of amputations in US
