Low blood glucose
(Hypoglycaemia)
 |
|
 |
|
Occurs
when the blood glucose level drops too low (below
4mmol/L).
This happens when there is a sudden increase in
insulin, when you:
 |
have taken
too much insulin or medicine at one time |
|
missed a meal or
taken too little food |
|
exercised or worked
harder than usual |
|
waited too long between
eating and injecting insulin |
|
have been vomiting
or having diarrhoea |
You may experience:
|
hunger |
|
weakness |
|
tiredness |
|
giddiness |
|
sweatiness |
|

What
you must do |
| |
|
 |
Check your blood glucose
with a glucometer, if you have one |
|
Raise your blood glucose level quickly
by taking some form of sugar e.g. you
may take one of the following: |
| |
 |
 |
 |
 |
half a glass
of
fruit juice |
2 to 4 teaspoons
of sugar, honey or syrup |
5 sugar cubes |
half a chocolate
bar |
|
|
Wait 10 to 15 minutes to see if you
are feeling better |
|
If you feel better, have your usual
scheduled meal. If you are not better,
take one of the sugar snacks again |
|
| |
|
Check your blood
glucose level half an hour later
to confirm that it is back to
normal. |
|
If symptoms continue after
the second sugar snack, seek medical
attention immediately. |
|
|
| |
If you experience:
|
loss of coordination
such as blurred vision or slurred speech |
|
confusion |
|
change in mood or behaviour |
|
fits |
|
loss of consciousness |
 |
your
family member or caregiver must call
an ambulance immediately as this would
mean more urgent treatment is necessary.
