Management of DM1
3-6 monthly HbA1c (<6.5%) QDS BM - before meals and bed (4-7mmol/l) Insulin Education - hypos, insulin devices DAFNE Avoid binge drinking
Complications of DM2
2x stroke 4x MI HTN Erectile dysfunction Retinopathy Neuropathy Nephropathy Diabetic foot PVD Glaucoma, cataracts Hyperosmolar hyperglycaemic state
Hyperosmolar hyperglycaemic state
High glucose WITHOUT ACIDOSIS (differs from DKA)
High Na, high Glu, normal pH
Manage with slow rehydration
The stages of diabetic retinopathy
- Background - hard educates, microaneurysms
- Pre-proliferation - cotton wool spots, haemorrhages
- Proliferation - new vessel formation
- Maculopathy
Causes of diabetes
Insulin resistance Disease of the pancreas Maturity onset diabetes of the young (MODY) Gestational Acromegaly Cushing's Steroids
Management of DM2
- Lifestyle - 16 weeks
- Metformin - 6m
- Add sulphonyluria/gliptin/piaglitazone/SGL2i
- Add another of above
- Insulin
Mechanism of metformin
Increase insulin sensitivity
Decrease GNG
ADRs of metformin
Lactic acidosis
GI sx
CI of metformin
Heart, renal, hepatic failure
Name some sulphonyurias
‘Zide’
Gliclazide, glipazide
Action of sulphonyurias
Increase insulin secretion
ADRs of sulphonylureas
Hypos
Weight gain
Action of glitazones
Increase sensitivity to insulin
Decrease GNG
ADRs of pioglitazone
Weight gain
Oedema
Bladder cancer
CI to pioglitazone
HF
Action of gliptins
DPP4i -> strops breakdown of GLP-1 -> suppresses appreciate, increases insulin release, inhibits glucagon secretion
What is the benefit with gliptins?
Weight loss
Action of SGL2i
SGL2 reabsorbs Glu in the PCT. Block this to reduce plasma glucose
ADRs of SGL2i
UTIs
thrush
