Hypoglycaemia (or ‘hypos’) and
hyperglycaemia are common complications of diabetes, and occur when the blood
sugar level is too low or too high, respectively. If untreated, either
condition can lead to the person falling unconscious and diabetic coma.
The person may display the following signs:
- Weakness, faintness, or hunger
- Palpitations and muscle tremors
- The person may appear confused or
- Sweating and cold, clammy skin
- Pulse may be rapid and strong
- Deteriorating level of response
The person may be carrying a diabetic's
warning card, glucose gel, tablets, or an insulin syringe.
What to do
- Help the person to sit or lie down.
- If the person has their own glucose gel/tablets
help them to take it. If not, give them a sugary drink, sugar lumps, chocolate
or any other sweet food.
- However, if they appear to be losing consciousness,
do not give anything to eat or drink as they may not be able to swallow or
drink it properly.
If the person falls unconscious:
- Call 999 or 112 for an ambulance
- If person’s breathing and circulation have
stopped, begin CPR
- If the patient loses consciousness but is
still breathing normally place them in the recovery
Symptoms may include any of the following:
- Warm, dry skin
- Rapid pulse and breathing
- Abdominal pain and vomiting
- Fruity/sweet breath
- Excessive thirst
- Need to urinate
What to do
- Allow person to self-administer insulin
- Give a non-sugary drink to prevent
- Dial 999 (or 112) for an ambulance
- If the casualty is unconscious, check for
signs of circulation and breathing and begin CPR if necessary.
Note: If you are unsure whether the person
is hyper- or hypo- gycaemic, give a sugary drink anyway, as this will do no
undue harm to a person who is hyperglycaemic.
