Diabetes Mellitus Flashcards
What is Diabetes mellitus?
= Metabolic disorder with multiple causes characteristic by chronically elevated blood glucose (hyperglycaemia) levels, with disturbances of carbohydrate, fat and protein
metabolism (endocrine disease)
What are the associated co-morbilities of Diabetes?
- Blindness
- non-traumatic limb amputation
- Cardiovascular disease
- Renal dialysis
- CKD
What is type 1 diabetes?
Type 1 = Absolute deficiency of insulin caused by pancreatic B cell destruction
What is Type 2 diabetes?
= caused by combination of:
- peripheral resistance of no insulin action
- inadequate secretory response by pancreatic B cells
What is gestational diabetes?
= glucose intolerance with onset or first recognition during pregnancy
- increase risk of maternal complications such as pre-clampsia
Symptoms of diabetes?
- Hyperosmolar effects of excessive glucose in
blood stream (diuresis) - Polyuria, polyphasia, polydipsia
- frequent infections
- Poor wound healing
- Signs of insulin resistance- hyperpigmentation of skin, skin tags, central obesity
Chronic complications of diabetes?
KNIVES K - Kidneys N - Nerves I - Infections V - Vasculature E - Eyes S - Skin
OGTT results Fasting
- Diabtes
- Normal NGT
- Impaired fasting glucose
Diabetes >7
Normal <6.1
Impaired fasting glucose 6.1-6.9
What are the three aspects for glycaemia management to BG control in T2DM?
- Diet
- Exercise
3 Medications - oral or injectable
Indications for insulin
- type 1 diabetes
- type 2 where inadequately controlled with diet, exercise and oral anti-diabetic drugs
What are the two common regimes for insulin (glycaemia management)
- Split mix
2. Basal Bolus
What is split mix and what are ads and Dis?
= 2 injections per day using mixed insulin preparations
- given before breakfast and dinner
Advantages:
- simple and convenient
- lower risk of hypos
Disadvantages
- decreased flexibility
- cannot skip meals
What is Basal Bolus and what are ad and dis?
= 4 injections per day.
- 3 injections short acting insulin before meals
- once daily (nightime) injections of long acting insulin
Advantages:
- flexibility
- better BSL control
Disadvantages:
- regular BSL monitoring
- fails to cover snacks
- higher risk of hypos
What are the four types of insulin?
Raid acting
Short acting
Intermediate action
Long acting
What are the injectable glycemic management medications?
- Insulin
- GLP-1 Antagonists
- DPP-4 inhibitors
- GLP1-GIP agonists
