Diabetes: Patient Education Survival Skills Class
4-Hour Session
Revised August 2004
Objectives
• Describe and contrast 2 principle types of diabetes
• List the diagnostic criteria for diabetes• Describe acute and chronic complications
of diabetes • Describe how to prevent complications of
diabetes• Describe diabetes self-management skills
Why Diabetes?
• 18 million cases in the United States• Estimated that 1/3 are unaware of diagnosis• Third leading cause of death in the U.S.• Leading cause of blindness• *Patient education is the cornerstone of
diabetes treatment and management*• *Complications can be prevented or
delayed through intensive treatment*
Diabetes is …
• A metabolic disease in which the body does not produce or properly use insulin to regulate the level of glucose (sugar) in the blood.
• In other words, your body cannot use the fuel in the blood for energy…..
Quick Review
Glucose: a sugar made in the body after food is digested. It is the body’s main source of energy (“fuel for the body”)
Insulin: a hormone produced by the pancreas that allows glucose to get into the cells to be used for energy (acts like a “key”)
Normal Glucose Values
• Normal Values
– Fasting Blood Glucose <100mg/dl
– Hemoglobin AIC 4 - 6 % (shows average glucose over past 60-90 days)
Goal < 7% with diabetes
Principle Types of Diabetes
Type 1: autoimmune pancreas does not produce insulin 10% of all diabetes
Type 2: pancreas does not produce enough insulin or it meets resistance 90% of all diabetes
Gestational Diabetes: occurs with pregnancy
Type 1 DMSigns and Symptoms
• Usually sudden and severe in onset
• Increased urination• Increased thirst• Increased appetite• Weight loss• Blurred vision
• Fatigue/weakness• Nausea/vomiting• Vaginal
itching/infections• Skin rashes
Type 2 DMSigns and Symptoms
• Onset more insidious• Early symptoms may
go unnoticed (3-5yrs)• Increased urination,
thirst, & hunger• Blurred vision• Fatigue• Sores that heal slowly
• Sexual dysfunction (erectile dysfunction)
• Infections (vaginal in women)
How Do We Diagnose Diabetes?
Fasting blood glucose level >126 mg/dl
Random non-fasting glucose >200 mg/dl
“Pre-Diabetes”: FPG 100-125 mg/dl
Research
• Studies show that an increased glucose level in the blood over many years can cause irreversible damage to the eyes, kidneys, heart, blood vessels and the feet.
Medications
Type 1 diabetes: insulin production stops
Insulin helps sugar (glucose) move into cells, where it is used to produce energy
Without insulin, glucose cannot enter the cells
Cells quickly waste away from lack of glucose CELL

Type 2 diabetes: insulin production and effectiveness are impaired
Insulin helps glucose move into cells, where it is used to produce energy
If not enough insulin is produced (insulin deficiency), not enough glucose can move into cells
When insulin is not used properly (insulin resistance), cells do not respond by taking in glucose
Cells slowly waste away from lack of glucose

Normally, the body regulates blood glucose levels by removing excess glucose
after a meal...
Ingested carbohydrates are metabolized into glucose and absorbed into the blood, causing high blood sugar (hyperglycemia)
The pancreas produces and secretes insulin, which helps move glucose into cells
Muscle, fat, and liver cells take up glucose from the blood
Blood glucose levels return to normal
…and releasing stored glucose back into the blood between meals
Gastrointestinal tract is empty; glucose must be supplied by the body for energy
The pancreas produces and secretes glucagon, stimulating the liver to release the glucose stored during meals
The liver releases glucose in response to low blood sugar (hypoglycemia)
Blood glucose levels return to normal
Type 2 diabetes evolves from 2 primary defects: insulin deficiency and insulin resistance
Glucose is absorbed into the blood, causing hyperglycemia
Pancreatic dysfunction leads to insulin deficiencyMuscle, liver, and
fat cells develop insulin resistance
Blood glucose levels remain high
Progression of untreated type 2 diabetes
Treatment Options
• First treatment is controlling diet and getting plenty of exercise
• Next option is use of oral medications
• Final option is use of insulin– This is needed in Type 1 diabetes patients
because their bodies do not make insulin
Drug therapy is needed in addition when diet and physical activity fail to correct
hyperglycemia
Insulin for type 1 or type 2 diabetes
Oral hypoglycemic agents for type 2 diabetes
Medication Types
• There are several ways in which these medications work– Causes your body to secrete insulin, decreases your
body’s resistance to insulin, decreases glucose production in your liver, prevents absorption of sugars in your diet
• Classes of drugs– Sulfonylureas and insulin-secreting agents– Biguanides– Alpha-glucosidase inhibitors– Thiazolidinediones
Oral hypoglycemics work in several different ways
Alpha-glucosidase inhibitors decrease gastro-intestinal absorption of glucose
Sulfonylureas increase insulin secretion
Thiazolidinediones reverse insulin resistance
Biguanides decrease release of glucose by the liver
Sulfonylureas
• Brand names– Amaryl
– DiaBeta
– Diabinase
– Glucotrol (XL)
– Glynase PresTab
– Micronase
• Generic names– glimepride
– glyburide
– chlorpropamide
– glipizide
– glyburide
– glyburide
Sulfonylureas
• Increase insulin release from your pancreas
• Help improve muscle sensitivity to insulin
• Pancreas must be actively making insulin to work
• Often taken 30 minutes before meals
D-phenylalanine Derivatives
• Nateglinide (Starlix)
• Increase insulin release from pancreas
• Short acting
• Take with each meal
• Do not take if meal skipped
Meglitinides
• Repaglinide (Prandin)
• Helps pancreas secrete more insulin right after meals, thus reducing post-meal blood sugar
• Works fast and short duration of action
• Take before meals
• Do not take if meal skipped
Biguanides
• Metformin (Glucophage, Glucophage XR)
• Decrease glucose production in the liver
• Increase muscle sensitivity to insulin
• Decrease insulin need
• May help with weight loss
• Improve cholesterol values
Thiazolidinediones
• Pioglitazone (Actos)
• Rosiglitazone (Avandia)
• Help make your cells more sensitive to insulin
Alpha Glucosidase Inhibitors
• Miglitol (Glyset)
• Acarbose (Precose)
• Blocks enzymes that digest starches in the stomach and intestines
• Reduces post-meal sugars
• Take with the first bite of meal
Medications may have to be combined to keep pace with this
progressive disease
Different oral hypoglycemic agents may be taken together
Insulin may be taken along with oral agents
Insulin: Rapid-Acting
• Rapid-acting: insulin lispro (Humalog) and insulin aspart (Novolog)
• Starts working in 5-15 minutes
• Lowers blood glucose most in 45-90 minutes
• Finishes working in 3-4 hours
Insulin: Short-acting
• Short-acting, regular (R) insulin
• Starts working in 30 minutes
• Lowers blood glucose most in 2-5 hours
• Finishes working in 5-8 hours
Insulin: Intermediate-acting
• Intermediate-acting, NPH (N) or Lente (L) insulin
• Starts working in 1-3 hours
• Lowers blood glucose most in 6-12 hours
• Finishes working in 16-24 hours
Insulin: Long-acting
• Long-acting, insulin glargine (Lantus)
• Starts working in 1 hour
• Lowers blood glucose evenly for 24 hours
• Finishes working in 24 hours and is taken once per day at bedtime
• Lantus should not be mixed together in a syringe with any other form of insulin
Insulin Use Considerations
• Insulin injection sites– Stomach (works fastest), thigh (works slowest), arm (works
at medium speed)
• Don’t change needle types or site because it may change absorption
• Keep insulin in refrigerator• Reduce pain
– Allow bottle to warm before injection (or leave one in use out), allow alcohol to dry, don’t reuse needles, don’t wipe needle with alcohol
• Dispose of needles properly
Type 2 diabetes is a progressive, but manageable, disease
Type 2 diabetes evolves from 2 primary defects:
insulin deficiencyinsulin resistance
Uncontrolled hyperglycemia leads to serious complicationsRisk for complications can be reduced by tight
glucose control
Summary
Summary, cont
Disease progression can be managed through a partnership between physician and patient
Treatment options:increased physical activity and nutritional therapy
sulfonylureas
other oral agents or insulin (as monotherapy or in combination)
Patient education and self-care are critical

Effects of Exercise on InsulinRequirement: Single Exercise Bout
• One hour of exercise requires an additional 15 grams of CHO either before or after activity.
• Metabolic response to exercise differs according to:– Timing of exercise in relationship to meal and medication
– Blood glucose level prior to activity
– Use of other medication
– Intensity and duration of the exercise
– Individual’s fitness level
Contraindications to Exercise

Diabetes and Carbohydrate Counting
Individual Meal Planning
Tips for success…– Refer to a dietitian– Major groups are represented: grains and breads
(starches), fruits, vegetables, meats, and dairy products – No more than 4-5 hours between meals – Meals should be at consistent times– Incorporate what you like to eat– Do not skip meals– All foods fit
Foods contain carbohydrates, fats, and proteins as sources of energy, plus many other important ingredients like water, vitamins, and minerals
Carbohydrates (CHO) in food have the most impact on the blood sugar
Although high fat foods can contribute to obesity, heart disease, and higher blood sugars in the long run, they play only a minor role in daily blood sugar control
Protein also plays a minor role in blood sugar control- half the protein we eat converts to glucose over a period of several hours but should only make up ~10-20% of our total calories
What are Carbohydrates?
• Grains (bread, cereal, rice, pasta)
• Fruits
• Vegetables
• Most milk products (not cheeses)
• Desserts and candies (refined sugars)
• -ose foods: sucrose, fructose, maltose
Counting CarbohydratesWHY?
• Offers more variety in choices• Information on food labels makes meal planning
easier• You can swap an occasional high sugar food (even
though it may contain fewer nutrients) for other carbohydrate-containing foods
• Better sense of dietary control and better glycemic control
Simple Carbohydrate Counting
• Work with a dietitian to plan how many grams of carbohydrates to eat at each meal and snack
• Choose foods from the carbohydrate- containing food groups to meet your allowance
• One serving from the Bread/Starch/Starchy Vegetable group= 15 grams of CHO
• One serving from the Fruit group= 15 grams of CHO
• One serving from the Milk group= 12 grams of CHO (round up to 15 grams for simplicity)
• One serving from the Non-Starchy Vegetable group= 5 grams of CHO (count as “free” but 3 svgs= 15 grams CHO)
*Meat and Fats do not contain CHO but contain protein and/or fat
*Alcohol counts as a fat (moderation defined as 2 drinks/day for men and 1 drink/day for women)
• Because Starch/Bread/Starchy Vegetables, Fruit, and Milk all contain approximately the same amount of CHO– they can be exchanged for one another
• Therefore, if your meal plan calls for 1 Starch, and you would prefer a piece of Fruit, that is fine
Carb Counting Examples
BREAKFAST
Cereal, dry 1 ½ cups 30 g CHO
Milk, skim 1 cup 12 g CHO
Blueberries ¾ cup 15 g CHO
Yogurt, light, 1 cup 15 g CHO
with fruit
Total = 72 g CHO
LUNCH
Bread, whole wheat 2 slices 30 g CHO
Turkey breast, sliced 2 oz (protein) 0 g CHO
Cheese, sliced 1 oz (protein) 0 g CHO
Banana, medium 1/2 15 g CHO
Crackers, wheat 5 15 g CHO
Juice, apple 4 oz 15 g CHO
Total = 75 g CHO

Diabetic Ketoacidosis (DKA)Complication mainly of Type 1 Diabetes
• Presence of high glucose over 250 mg/dl, ketones in blood and urine
• Dehydration, abdominal pain, fluid & electrolyte imbalance
• Can lead to coma and death if not treated• Get transported to an Emergency Room!• Tx: insulin, IV fluids, treatment of underlying
cause
Hyperosmolar Hyperglycemic State (HHS)
Complication of Type 2 Diabetes
• 4 Primary Features– Severe high glucose (glucose>600 mg/dl)– Dehydration – No ketones in urine– Confusion, lethargy, may mimic a stroke
• May lead to coma and death if not treated• Get transported to an Emergency Room!• Tx: insulin, IV fluids, treatment of underlying
cause
Chronic Complications
Chronic Complications
• Diabetes can damage the lining of blood vessels and nerves by causing scarring and stiffness. The vessel linings can trap cholesterol and plaque leading to blockage (atherosclerosis).
• **The heart must work harder to pump blood through these blocked vessels leading to chronic complications
Cardiovascular Disease(heart and blood vessels)
• Accelerated Atherosclerosis (rapid, younger age). “hardening of the arteries” or
“Coronary Artery Disease”
• Heart Attacks
• Heart Failure
• Strokes
Lower Extremities
• Leg ulcers, gangrene, increased risk of infection
• **Most common cause of amputations
• Pain in legs and calves (“peripheral vascular disease”)
Foot Complications
• Poor sensation
• Poor recovery from injury
• Decreased sweating
• Dry skin
• Ulcerations
• Infection
• Gangrene
Nerve Complications
• Damage to nerves causes numbness, burning, and pain (“peripheral neuropathy”)
• Can lead to trouble walking and maintaining balance
Autonomic Neuropathies(nerves that control bodily functions)
• Impotence
• Gastroparesis (slow emptying of the stomach)
• Diabetic diarrhea
• Neurogenic bladder (loss of bladder tone)
Eye Complications
• Retinopathy (hemorrhages in the back of the eye and scar formation)
• Impaired vision
• Blindness – Leading cause of blindness
• Cataracts
Kidney Disease
• Can no longer filter wastes out of the body• Protein spills in the urine• No warning signs• Diabetes is the most common cause of kidney
disease requiring dialysis and transplant• Can be detected early with blood and urine tests
(chemistries and microalbumin)• Prevention with medications (ask your provider)
Report These Symptoms!!
• Any chest pain, chest tightness, chest fullness or pressure
• Trouble breathing• Increased fatigue• Wounds that do not heal• Calf pain• Changes in vision• Headaches• Swelling• Change in mental status
