Q

Is insulin required for DM2?

A

Required for some. Disease is progressive and insulin treatment may need to be added to treatment regimen

24
Q

What complications are common for both forms of DM?

A

Vascular and neurological complications

25
What is presentation of DM1?
Polyuria, polydipsia, weight loss, fatigue, ketosis, hyperglycaemia, nausea, vomiting, blurry vision
26
What are risk factors of DM1?
- Genetic susceptibility - Autoimmunity - Environmental (exposure to viruses and triggers in diet)
27
What are risk factors for DM2?
- Genetics - Obese - Decreased physical activity - High fat diet - Age - Ethnicity - Hypertension - History of gestational diabetes
28
What are long term complications of diabetes?
- Stroke - Hypertension - Dermopathy - Artherosclosis - Nephropathy - Peripheral neuropathy - Neurogenic bladder - Infections - Erectile dysfunction - Islet cell losee - Gastroparesis - Coronary artery disease - Retinopathy
29
How does hypertension occur in diabetes?
Hypertension progresses along with nephropathy
30
What is dermopathy?
Small brown lesions on skin
31
What is nephropathy?
Damage to kidneys from hyperglycaemia
32
What is peripheral neuropathy?
Loss of peripheral sensation due to damage to the axons of the neurons
33
What is neurogenic bladder?
Retention of urine in the bladder caused by diabetic neuropathy
34
Why are diabetic patient at increased risk of infections?
Impairment of immune system due to hyperglycaemia
35
Why does erectile dysfunction occur with diabetic patients?
Due to microvascular disease, peripheral and autonomic neuropathy
36
What does peripheral vascular disease do?
Due to narrowed blood vessels there is decreased perfusion, decreasing wound healing
37
What is gastroparesis?
Delayed emptying of stomach due to impaired neural control. This occurs since hyperglycaemic damages the axons of nerve cells
38
What is coronary artery disease?
Damage to blood vessels causing buildup of plaque due to macro vascular complications
39
What is diabetic retinopathy?
Damage to blood vessels in the eye from microvascular changes from hyperglycaemic
40
What drugs address insulin resistance by increasing cellular uptake of glucose and/or improving cellular insulin sensitivity?
- Biguanides (Metformin) - Sulfonylureas (Glipizide) - Thiazolidinediones (Actos)
41
What drugs increased insulin production by stimulating beta cells or mediating factors that prevent beta cell response to glucose levels
- Sulfonylureas (Glipizide) - Didpeptidyl Peptidase-4 Inhibitors (Sitagliptin) - Glucagon-like peptide 1 receptor agonists (exentide)
42
What drugs decrease hepatic glucose production?
- Biguanides (Metformin) - Sulfonylureas (Glipizide) - Didpeptidyl Peptidase-4 Inhibitors (Sitagliptin) - Glucagon-like peptide 1 receptor agonists (exentide)
43
What drugs reduce blood glucose levels by delaying carbohydrate digestion?
- Alpha-Glucosidase Inhibitor (Acarbose) | - Glucagon-like peptide 1 receptor agonists (exentide)
44
What is the route, onset, peak and duration of Rapid Acting Insulin?
- Route - subcutaneous - Onset - 30 minutes - Peak - 1-3 hours - Duration - 8 hours
45
What is an example of Rapid Acting Insulin?
Aspart
46
What is the route, onset, peak and duration of Short Acting Insulin?
- Route - subcutaneous - Onset - 10-20 minutes - Peak - 1-3 hours - Duration - 3-5 hours
47
What is an example of Short Acting Insulin?
Lipsro
48
What is the route, onset, peak and duration of Intermediate Acting Insulin?
- Route - subcutaneous - Onset - 1-1.5 hours - Peak - 4-12 hours - Duration - 12-24 hours
49
What is an example of Intermediate Acting Insulin?
Isophane
50
What is the route, onset, peak and duration of Long Acting Insulin called Detemir?
- Route - subcutaneous - Onset - 1-2 hours - Peak - 3-4 hours - Duration - up to 24 hours
51
What is the route, onset, peak and duration of Long Acting Insulin called Glargine?
- Route - subcutaneous - Onset - 1-1.5 hours - Peak - no peak - Duration - 24 plus hours
52
What causes hypoglycaemia?
- Not enough food - Not enough carbohydrates - Missing or delaying meal - Introducing exercise without adjusting insulin level - Taking too much insulin - Excessive alcohol without carbohydrates
53
How to manage hypoglycaemia?
1) Consume quick acting carbohydrate 2) Retest glucose level after 10 minutes and consume more if below 4.0mmol/L 3) Consume more substantial carbohydrate
54
How to monitor diabetes?
- Blood draws (HbA1c and lipid profile - Self blood glucose monitoring - Urine testing for microalbuminuria - Diabetic foot exams - Self-management skills - Weight and BMI - Healthy eating plan - Diabetic retinopathy screening
55
What are the functional health patterns of diabetics?
- Activity and exercise - Coping - Sexuality-reproductive pattern
56
What are interventions for diabetes?
- Education on disease process - Exercise - Medications - Diet - Monitoring
