A diabetic attack—whether it's a sudden drop or spike in blood sugar—can be scary, both for the person going through it and anyone nearby. But knowing what to do in the moment can make all the difference.
First things first: stay calm. That might sound easier said than done, but a clear head helps you respond quickly and effectively.
There are two types of diabetic emergencies to look out for: hypoglycemia (low blood sugar) and hyperglycemia(high blood sugar).
If it is low blood sugar hypoglycemia
This tends to come on fast. Common symptoms include shakiness, sweating, confusion, dizziness, or even irritability. If someone is conscious and able to swallow, give them something with quick-acting sugar: fruit juice, regular soda (not diet), glucose tablets, or even a spoonful of honey or sugar. Follow that up with something more substantial like crackers or a sandwich to keep their levels stable.
If the person becomes unresponsive, don’t try to give them food or drink—that could cause choking. Call 911 immediately. If they have a glucagon emergency kit and you’re trained to use it, now’s the time.
If it’s high blood sugar (hyperglycemia):
This develops more gradually and may involve extreme thirst, frequent urination, nausea, dry mouth, or a fruity smell on the breath. If the person is alert and able, they should check their blood sugar and possibly take insulin if their doctor has instructed them to do so in these situations.
Encourage them to drink water to stay hydrated and help flush out the excess sugar. But again, if they’re confused, vomiting, or unable to stay awake, it’s time to call emergency services.
A few extra tips:
- If the person wears a medical ID bracelet or has emergency instructions on their phone, check those right away.
- Never assume which type of diabetic episode they’re having if you’re unsure. When in doubt, treating for low blood sugar is safer in the short term.
- Once things have stabilized, follow up with a doctor to figure out what caused the episode and how to prevent it in the future.
The bottom line? Diabetic attacks are serious, but with quick thinking and a little preparation, you can help turn a dangerous moment into a manageable one.
