25
what is the gold star insulin regimen

When a patient becomes unwell with diabetes what rules come into play
the sick day rules
102
what do the sick day rules state in regards to lifestyle advice
Ensure to STAY HYDRATED DONT FAST IF CANNOT EAT take sugary drinks and or icecream to replace the blood sugar IF CAN BLOOD SUGAR MONITOR do every 2 - 4 hours IF NOT look out for signs of hyperglycaemia

105
Why does metformin need to be stopped during sick days
increased chance of lactic acidosis due to the increased thirst when we are sick
106
Why do Sulphonylureas need to be stopped during sick days if cannot eat or drink
If unable to eat or drink then makes more prone to hypoglycaemia
107
Why do GLP-1 Analogues need to be stopped during sick days
dehydration leads to higher chance of serious side effects

Why do SGLT2 Inhibitors need to be stopped during sick days
higher chance of keto acidosis
108
what adjustment to the insulin should be made when we are taking a sick day and we have a blood glucose of less than 4 mmol/ l
firstly treat the hypo by having a sugar snack e.g. jelly babies or ice cream then reduce the regular insulin dose by 20%
109
what adjustment to the insulin should be made when we are taking a sick day and we have a blood glucose of more than 13mmol/l
Take carbs as a meal replacement Sip sugar free fluids 100ml per hour to stay hydrated Increase insulin dose by either 2, 4 or 6 units to increase depending on how high it is over 13 if < 17 then 2 if < 22 then 4 if > 22 then 6
