What To Do

What To Do If Someone Has a Diabetic Seizure

Key Takeaway: If someone with diabetes has a seizure, protect them from injury, time it, call 000, and check breathing as soon as the seizure stops. Do not restrain them and do not give food or drink until they are fully awake and can swallow safely.

Many diabetic seizures are linked to severe hypoglycaemia, but your first aid does not depend on proving the cause. Treat it as a medical emergency and keep the person safe until paramedics take over.

🚨 What To Do Immediately

1. Protect them from injury and time the seizure

Move away hard, hot, or sharp objects. Put something soft under the head if you can do that safely. Start a timer straight away. Healthdirect’s seizure guidance says seizure length matters, and a seizure lasting 5 minutes or more needs urgent emergency response.

2. Call 000 early

If the person has diabetes and is having a seizure, do not wait to see if they “snap out of it”. Healthdirect includes diabetes among the reasons to call an ambulance for a seizure, and severe hypoglycaemia guidance tells you to treat drowsiness, unconsciousness, or seizure as an ambulance case.

3. Do not hold them down and do not put anything in the mouth

Better Health Channel’s seizure first aid advice says not to restrain the person and not to put anything in their mouth. That includes glucose gel, jelly beans, water, tablets, or insulin while the seizure is happening.

4. When the seizure stops, check breathing immediately

If they are breathing but not fully awake, place them in the recovery position and keep watching closely. If they are not breathing normally, follow DRSABCD and start CPR.

5. Stay with them and keep the area calm

After a seizure, people can be confused, frightened, drowsy, or slow to respond. Do not leave them alone, and do not let them stand up or walk off too quickly.

📞 Call 000 and Say “Diabetes Emergency”

This is not a “watch and wait” situation. Call 000 and say the person has diabetes and is having, or has just had, a seizure.

  • Tell the operator it is a diabetes emergency with seizure activity
  • Give the exact location and whether the person is breathing normally
  • Say when the seizure started and whether a second seizure has happened
  • Mention insulin, diabetes medication, pregnancy, injury, alcohol, or recent illness if you know about it

Healthdirect’s seizure page specifically includes diabetes as a reason to call 000. If the seizure happened in a bath, pool, or other water setting, our guide to what to do if someone has a seizure in water covers the extra drowning risk.

🧠 Why a Diabetic Seizure Is an Emergency

When people say “diabetic seizure”, they usually mean a seizure happening in a person with diabetes, often because blood glucose has dropped dangerously low. Severe hypoglycaemia can affect the brain enough to cause confusion, collapse, unconsciousness, or seizure.

Healthdirect and Better Health Channel both note that severe hypoglycaemia can lead to unconsciousness or seizure. Your job is not to diagnose the exact glucose number on the spot. Your job is to protect the airway, protect from injury, and get urgent medical help.

Even if the seizure stops quickly, the emergency is not over. A seizure linked to diabetes can mean the person still needs monitoring, more treatment, and a medical review to prevent it happening again.

If the person only seems shaky, sweaty, confused, or faint rather than actively seizing, our guide to what to do if someone faints from low blood sugar covers the earlier-stage hypo response.

🍬 When Glucose or Glucagon Matter

Nothing by mouth during the seizure or while they cannot swallow safely

If the person is seizing, unconscious, or too drowsy to swallow, do not give sugar, fluids, food, or tablets by mouth. That creates a choking risk. Both Healthdirect and Better Health Channel say severe or unconscious hypoglycaemia should not be treated by mouth.

Once fully awake and able to swallow, glucose may help

If the seizure has stopped, the person is awake enough to swallow safely, and the ambulance is on the way, you can follow their personal diabetes plan or give fast-acting glucose such as glucose tablets, gel, fruit juice, or regular soft drink if that is what they normally use.

Glucagon only if it is available and you know how to use it

Healthdirect says that if the person has a glucagon injection and you know how to use it, you should administer it. Better Health Channel also says glucagon can be given by a trained support person for severe or unconscious hypoglycaemia. If you are not trained, focus on 000, recovery position, and breathing until paramedics arrive.

❌ What Not To Do

Do not hold them down.

Do not put anything in the mouth during the seizure.

Do not force jelly beans, glucose gel, water, or tablets into someone who is unconscious or not swallowing properly.

Do not give insulin because you think the problem “must be high sugar”. A seizure in a person with diabetes needs emergency care, not guesswork.

Do not leave them alone once the seizure stops, even if they seem embarrassed or want to get up quickly.

🎓 Why First Aid Training Matters

A diabetic seizure is a high-pressure scenario because you may be thinking about both seizure first aid and a diabetes emergency at the same time. In a HLTAID011 Provide First Aid course, you learn how to respond to seizures, unconscious casualties, breathing checks, CPR, and recovery-position care. That kind of first aid training helps you act in the right order when the situation feels chaotic.

FAQs

Do I always call 000 for a diabetic seizure?

Yes. A seizure in a person with diabetes should be treated as a medical emergency. Call 000, protect them from injury, and check breathing once the seizure stops.

Should I put sugar or glucose gel in their mouth during the seizure?

No. Do not give anything by mouth while they are seizing, unconscious, or too drowsy to swallow safely. Wait until they are fully awake and able to swallow, or follow paramedic instructions.

What if they carry glucagon?

If glucagon is available and you know how to use it, Healthdirect says it can be given for severe hypoglycaemia. If you are not trained, focus on 000, recovery position, and breathing until paramedics arrive.

What if the seizure stops and they look better?

Stay with them and keep the ambulance call in place. A diabetic seizure can settle quickly and still need urgent treatment and medical review.

• Do not restrain them
• Do not put anything in the mouth
• When it stops, check breathing
• Breathing but unconscious → recovery position
