1
Q

Diabetes mellitus

A
  • diabetes = a group of metabolic conditions meaning a malfunction in the way the body either produces insulin, uses insulin, or both
    Insulin:
  • pancreas makes insulin
  • insulin is a hormone that helps transport glucose from food into the body’s cells to be used for energy
  • helps regulate glucose levels (used for energy)
    Blood glucose:
  • fluctuates throughout the day
  • diabetes causes the levels to go way above (hyperglycemia) or below normal (hypoglycemia)
  • what we eat, how much we move, how we’re feeling

Q

What happens when having lack of insulin?

A
  • the body breaks down its own fat or lipids to produce an energy source = ketones
  • total lack of insulin can create dangerous and life threatening levels of ketones and a persistent high blood glucose level can lead to complications affecting multiple tissues and organ systems

Q

Types of diabetes

A

The American Diabetes Association (ADA) classifies diabetes into 4 general categories:
- Type 1 diabetes (autoimmune)
- Type 2 diabetes (risk factors that are non-modifiable like age, ethnicity, and family history and modificable like unhealthy diet, obesity, and lack of physical exercise)
- Gestational diabetes mellitus (GDM) (during pregnancy)
- specific types of diabetes due to other causes (rare single gene mutation)

Q

Type 1 diabetes

A
  • your body does not make insulin
  • a condition of complete or absolute insulin deficiency
  • autoimmune beta cell destruction that requires insulin replacement
  • can develop at any age
  • in adults = type 1 diabetes accounts for 5-10% of all diagnosed cases
  • it occurs most frequently in children, with just over 18,000 youth newly diagnosed each year
  • type 1 symptoms can develop in just a few weeks or months
    • once symptoms appear, they can be abruptly severe
    • often individuals present in an acutely ill state, many times with a life-threatening condition

Q

Type 1 diabetes diagram (slide 7)

A

Healthy:
- pancreas procures insulin
- insulin moves glucose to the cells
Diabetic:
- immune cells destroy beta cells in the pancreas that produces insulin
- pancreas cannot produce insulin
- more glucose ends up in the blood
- there is no insulin to transport the glucose to the cells and is just hanging out in the bloodstream

Q

Etiology of type 1 diabetes

A
  • occurs more in kids
  • an autoimmune reaction that destroys the insulin-producing beta cells in the pancreas
  • genetic susceptibility coupled with other factors
  • environmental factors might precipitate the disease
  • diet may precipitate the disease
  • the relationship between viral infection and type 1 diabetes development is supported by many studies alongside the indication that viruses have the potential to induce beta cells damage and reduce insulin production

Q

Type 2 diabetes

A
  • does produce insulin, but either produces less insulin than it should or it doesn’t know how to use insulin
  • a condition where the body does not use insulin properly due to a progressive loss of adequate beta cell insulin secretion
  • insulin deficiency = doesn’t make adequate insulin
  • insulin resistance = when the body cannot use insulin well
  • body needs more insulin to help glucose enter cells and the pancreas makes more insulin at first
  • 90-95% of all cases of diabetes

Q

Etiology of type 2 diabetes

A
  • insulin resistance and beta cells dysfunction are known to be the major factors associated with type 2 diabetes
  • genetics, age, ethnicity, and lifestyle factors such as being overweight or obese and not being physically active
  • body fat location and distribution, in particular the extra-abdominal fat, is associated with insulin resistance
  • although individuals can develop type 2 diabetes at any point in time, even during childhood, it most often occurs in middle-aged and older adults 45 years or older
  • presence of high blood pressure, abnormal cholesterol or triglyceride levels, smoking, and use of certain medicines such as steroids

Q

Gestational diabetes

A
  • pregnant women go take a glucose tolerance test and then 2 hours later, get bloodwork to see blood sugar level
  • transient in nature
  • typically diagnosed in 2nd or 3rd trimester of pregnancy in women that might not have clearly overt diabetes prior to gestational
  • it is due to either hormones blocking the action of insulin to the body or when the body is not able to make and use all the insulin in needs during pregnancy leading to insulin resistance
  • every year, 2-10% of pregnancies in the U.S. are affected by gestational diabetes
  • postpartum, blood sugar levels usually return to normal; however, about 50% of women with gestational diabetes will eventually develop type 2 diabetes
  • high blood glucose levels in mother
  • brings extra glucose to the baby
  • causes baby to put on extra weight (10-12 pounds)

Q

Other specific types of diabetes

A
  • monogenic diabetes = related to a change or defect in a single gene and include neonatal diabetes mellitus (NDM) and maturity-onset diabetes of the young (MODY)
  • NDM = a rare condition that occurs in up to 1 in 400,000 infants in the first 6-12 months of life and is often mistaken for type 1 diabetes
  • MODY = characterized by onset of hyperglycemia due to impaired insulin secretin at an early age (typically before age 25 and accounts for up to 2% of all cases of diabetes in the United States in people ages 20 and younger
  • other specific types of diabetes include diseases of the exocrine pancreas (ex: cystic fibrosis-related diabetes (CFRD) and pancreatitis) and drugs or chemical-induced diabetes (ex: with glucocorticoid use, in the treatment of HIV/AIDS, or after organ transplantation)

Q

Prediabetes

A
  • blood glucose levels within the range of normal to high and meet other diagnostic criteria for diabetes
  • individuals in this intermediate zone present with impaired fasting glucose levels (100-125 mg/dL) and impaired glucose tolerance levels (140-199 mg/dL)
  • prediabetes is associated with obesity, dyslipidemia (high cholesterol), and hypertension (HTN), and those diagnosed are at an increased risk for diabetes and cardiovascular disease (CVD) in the future
  • lifestyle modifications including participation in prevention programs that target increasing physical activity, losing weight, managing stress, problem solving, and eating health can delay or prevent progression to type 2 diabetes

- smaller size
- high urine protein

33
Q

Hemodialysis

A
  • when kidneys stop functioning, you have to go on a dialysis
  • dialysis = a port on somebody’s arm (sometimes in their chest) that takes out the blood into the machine to filter it and then puts the blood back into the body
  • doesn’t urinate if you’re on dialysis
  • if can’t do dialysis on time, you have all this unfiltered blood in your body and you gain weight, have extra fluid
34
Q

Macrovascular complications

A
  • affect the cardiovascular system and include hypertension, CVD, CVA, and PAD
  • poor glycemic control have higher rates of hypertension
  • high blood sugar levels leads to atherosclerosis = CVA
  • aggressive blood pressure and cholesterol management are critical to addressing macrovascular complications with individuals with diabetes
35

  • type 3 diabetes is a term used to describe the hypothesis that Alzheimer’s disease is caused by insulin resistance in the brain (not widely accepted by the medical community as a clinical diagnosis)
  • too much blood sugar kills of the blood vessels in the brain, leading to brain fog
38
Q

Diabetes distress

A
  • refers to the psychological impact of living with a chronic and progressive condition and the emotional response to stressors such as medications and dosing schedules, adherence to diet, anxiety about existing or possible complications, guilt for periods of poor self-management, impact of the disease on family or friends, feelings of guilt or shame, or fear of hypoglycemia

41
Q

Medical management of diabetes

A
  • blood glucose monitoring
  • glucometer
  • continuous glucose monitoring system (CGM)
42
Q

Blood glucose monitoring

A
  • glucose monitoring has been shown to improve A1C levels and decrease diabetic complications for people with type 1 diabetes
  • identification of hypoglycemia, hyperglycemia, and general glycemic variability allows a person with diabetes to determine how blood glucose levels may be affected by diet, activity level, stress, illness, injury, and/or medications
  • tracking trends or patterns in blood glucose levels provides information used to determine the effectiveness of current management and assists in the modification and tailoring of insulin or medication dosages
43
Q

Glucometer

A
  • a blood sample is taken using a small lancing device and the sample is placed on the test strip for analysis by the glucometer
  • type 1 diabetes test their blood sugar 4-10 times a day
  • before and after meals or snacks
  • before and after exercise
  • before bedtime
  • if there’s a suspicion of hypoglycemia or hyperglycemia
  • before driving or travel
  • while taking a new medication
  • type 2 diabetes should check their blood sugar several times a day if they are using insulin
44
Q

Continuous glucose monitoring system (CGM)

A
  • a reusable transmitter and small subcutaneous catheter inserted into the body to obtain real-time glucose readings from interstitial fluid
  • readings are taken at regular intervals and can be sent to an insulin pump, a smart phone or other receiver with the CGM system app
  • CGM software allows blood glucose results to be shared in real time with others involved with the person’s care, such as a school nurse, coach, or parent
  • helpful in decreasing hypoglycemic fear and diabetes-related stress
45
Q

Medical management for type 1 diabetes

A
  • type 1 diabetes is a lifelong condition that requires significant and vigilant ongoing medical management
  • daily routines must incorporate insulin replacement, frequent blood glucose monitoring, and carbohydrate, protein, and fat counting
  • insulin replacement injections
46
Q

Insulin replacement

A
  • insulin is typically injected subcutaneously in the fat under the skin to reach the bloodstream (cannot be taken orally because its proteins would be destroyed during the digestive process)
  • delivered using a syringe, an insulin pen, or via continuous subcutaneous infusion using an insulin pump
  • Bolus insulins = rapid-acting insulins (ex: NovoLog, Apidra, Humalog) and short-acting insulins (ex: Humulin R, Novolin R) are absorbed quickly into the bloodstream (begins working 5-30 mins after injection, making them a good choice for a mealtime or correction bolus)
  • Basal insulins = intermediate-acting insulins and long-acting insulins are typically used to control glucose using the night and between meals (begins working 2-4 hours after injection and remains in the bloodstream for up to 12-24 hours)
  • may use both = typical insulin protocols require once or twice daily injections of basal insulin and several bolus insulin injections taken with each meal or snack
47
Q

Insulin protocols

A
  • a thorough understanding of portion size, carbohydrate counting, the effects of fats and proteins, glycemic index, and an understanding of dosage ratios is all necessary for effective and safe basal/bolus insulin therapy
48
Q

Insulin pump

A
  • insulin pumps are small devices that are attached to the body on the skin, or by way of a small tube and cannula
  • programmed to work like the pancreas, delivering continuous customized basal doses of insulin and user-directed bolus doses to cover meals, or to correct hyperglycemia
49
Q

Medical management for type 2 diabetes

A
  • lifestyle changes = initially managed with the incorporation of nutritional strategies and regular exercise into daily routines
  • patient education
  • nutrition therapy = must understand the impact of facts, carbohydrates, and proteins in their blood sugar; understand the glycemic index of foods, or how they affect blood glucose levels; foods high in simple sugar have a higher glycemic index and affect blood glucose more significantly and more quickly, while whole foods higher in complex carbohydrates have lower glycemic index and are more slowly digested, absorbed, and metabolized, lessening their immediate impact on blood glucose
50
Q

Regular exercise (lifestyle change)

A
  • improved control of blood glucose, improved cardiovascular health, contributes to weight loss, and increased overall well-being
  • recommends that children or adolescents with type 2 diabetes engage in a minimum of 60 minutes of moderate-intense aerobic activity per day and resistive strengthening exercise at least 3 days per week
  • for adults, the recommendation is 150 minutes or more of moderate-vigorous aerobic activity per week and 2-3 sessions of resistive strengthening exercise per week
  • periods of prolonged sitting should be avoided and it is recommended that older adults with diabetes also engage in flexibility and balance training 2-3 times per week
51
Q

Weight control (lifestyle change)

A
  • beneficial in the treatment of type 2 diabetes and can delay the progression of prediabetes to a diagnosis of diabetes
  • modest and sustained weight loss has been shown to improve insulin sensitive and beta cell function yielding improved blood glucose control
  • decrease the need for glucose lowering medications
52
Q

Pharmacological management

A

Glucose lowering oral medications:
- decreased the release of glucose from the liver
- increases insulin production
- improves insulin sensitivity
- delaying breakdown of sugar
Metformin:
- decreases the release of glucose from the liver
- relatively low incidence of side effects
Injectable medications are also available to treat type 2 diabetes:
- these drugs work to lower the amount of glucose released by the liver, keep the food in the stomach longer, and increase insulin production
Effectiveness may decrease over time:
- insulin replacement via injection or insulin pump to manage blood glucose

53
Q

Occupational implications on health management (diabetes)

A
  • developing, managing, and maintaining routines for health and wellness by engaging in self-care with the goal of improving, or maintains health, including self-management, to allow for participation in occupations
  • adjust eating, exercise, and stress management habits and routines
  • monitor and control symptoms, manage medications, and communicate with the health care system
  • self-management education is critical for implementing and sustaining performance patterns that prevent further complications and support overall health
  • informed decision-making, collaboration with the healthcare team, enhanced problem-solving behaviors, and the development of new self-care skills
  • complete and thorough understanding of blood glucose monitoring, insulin dosage, dietary intake, device care and maintaining, the effects of activity and exercise, and signs and symptoms of hypoglycemia and hyperglycemia is essential
54
Q

Occupational implications on ADLs (diabetes)

A
  • periodontal disease
  • skin care
55
Q

Occupational implications on IADLs (diabetes)

A
  • shop for groceries and prepare health meals
