A

at night

generates ketones which causes a drop in pH

Q

What is the onset, peak, and duration of Rapid-Acting insulin ?

A
  • onset: 15-30 mins
  • peak: 0.5-2.5 hrs
  • duration: 3-6 hrs
19
Q

What is the onset, peak, and duration of Short-Acting insulin ?

A
  • onset: 0.5-1 hr
  • peak: 1-5 hrs
  • duration: 6-10 hrs
20
Q

What is the onset, peak, and duration of Intermediate-Acting insulin ?

A
  • onset: 1-2 hrs
  • peak: 6-14 hrs
  • duration: 16-24 hrs
21
Q

What is the onset, peak, and duration of Long-Acting insulin ?

A
  • onset: 70 min
  • peak: none
  • duration: 18-24 hrs
22
Q

What is a Basal-Bolus regimen ?

A

closely mimics the body’s normal response and release of insulin
- basal is the maintenance insulin (intermediate or long-acting)
- bolus is what you give before eating to prepare for glucose release (rapid or short-acting)
- personalized to each pt

23
Q

Where do you get the fastest absorption of insulin ?

A

the abdomen
- then the arm, thigh, and buttock

24
Q

What happens if you insert insulin into a lump ?

A

lipodystrophy

25
Q

What do insulin pumps do ?

A

deliver a basal rate of regular or rapid acting insulin
- or program to deliver a bolus dose with each meal

26
Q

What is the minimum total carbohydrate ?

A

130 g/day
- 45-60 g/meals

27
Q

How does exercise affect glucose levels ?

A
  • always encourage exercise and never restrict
  • this enhances insulin absorption
  • it lowers glucose levels (eat a snack before exercising or exercise after a meal)
  • adjust insulin if needed
  • check glucose before, during and after activity
28
Q

What is Somogyi Effect ?

A

hyperglycemia present upon waking
- an overdose of insulin which causes hypoglycemic between 2-4 am
- you go hypoglycemic at night and you body releases glucose and glucagon to correct it and causes you to wake up hyperglycemic

29
Q

What is Dawn Phenomenon ?

A

hyperglycemia present upon waking
- peaks in adolescence and young adulthood (maybe because of growth hormone)
- growth hormone and cortisol is released at night and this causes your glucose to increase causing hyperglycemia

30
Q

What are some S&S and Tx of Somogyi Effect ?

A
  • S&S: HA, night sweats, nightmares
  • Tx: adjust insulin dose down or add bedtime snack
31
Q

What is the Tx for Dawn Phenomenon ?

A

adjust timing of insulin or possible increase in insulin

32
Q

How is the pancreas affected by Type 2 DM ?

A
  • defective B-cell secretion of insulin
  • insulin resistance stimulates increased insulin secretion
  • eventual exhaustion of B-cell in many people
33
Q

How is the liver affected by Type 2 DM ?

A
  • excess glucose production
  • inappropriate regulation of glucose production
34
Q

How is the Adipose Tissue affected by Type 2 DM ?

A
  • decreased adiponectin and increased leptin
  • results in altered glucose and fat metabolism
35
Q

How are the muscles affected by Type 2 DM ?

A
  • defective insulin receptors
  • insulin resistance
  • decreased uptake of glucose by cells resulting in hyperglycemia
36
Q

What A1C levels indicate someone with diabetes ?

A

> 6.5%

37
Q

What A1C levels indicate someone who is pre-diabetic ?

A

5.7%-6.4%

38
Q

What A1C levels indicate someone who is perfectly healthy ?

A

<5.6%

39
Q

What determines the difference in someone who is Type 1 DM and Type 2 DM ?

A

islet cell autoantibodies
- Type 1 DM is because of an autoimmune reason

40
Q

How does Metformin/Biguanide affect the body ?

A
  • reduces glucose production by liver
  • enhance insulin sensitivity at tissues
  • improve glucose transport into cells
  • can cause weight loss
  • beneficial against plasma lipids
41
Q

How do Sulfonylureas affect the body ?

A

Glipizide and Glyburide
- increases insulin production from pancreas (beta cells)
- risk of hypoglycemia and weight gain

42
Q

What does Meglitinides affect the body ?

A

increase insulin production from the pancreas

43
Q

What does Thiazolidinediones affect the body ?

A

improve insulin sensitivity, so no hypoglycemia concerns
- linked to cardiovascular problems, so rarely used

44
Q

What is the difference between Ozempic and Wegovy ?

A
  • Ozempic is a lower dose and was only studied in relation to control of glucose
  • Wegovy is a higher dose and was only studied in relation to weight loss
