Diabetes is a common condition affecting millions worldwide. While many individuals with diabetes manage their condition effectively through medication, diet, and exercise, emergencies can arise. 

Knowing how to provide first aid in these situations is crucial, as quick and informed action can prevent serious complications or even save a life. Here, we will guide you through the steps to take during a diabetic emergency and highlight when it’s necessary to involve the emergency services.

Understanding Diabetic Emergencies

Diabetic emergencies typically occur when blood sugar levels become too high (hyperglycaemia) or too low (hypoglycaemia). Each scenario requires different first aid responses, and understanding the symptoms can help you identify the type of emergency and act appropriately.

Hypoglycaemia (Low Blood Sugar)

Hypoglycaemia happens when blood sugar levels drop below normal, often due to skipping meals, taking too much insulin, or exercising excessively without adjusting food intake. Symptoms include:

• Sweating
• Shakiness
• Confusion or disorientation
• Irritability
• Slurred speech
• Loss of consciousness in severe cases

Hyperglycaemia (High Blood Sugar)

Hyperglycaemia occurs when blood sugar levels are too high, often because of insufficient insulin, stress, or illness. Symptoms include:

• Excessive thirst
• Frequent urination
• Fatigue
• Blurred vision
• Fruity-smelling breath (a sign of diabetic ketoacidosis, a severe condition)

First Aid for Hypoglycaemia

1. Recognise the Symptoms: If the person appears shaky, sweaty, or confused, suspect low blood sugar.
2. Offer Fast-Acting Sugar: If the person is conscious and able to swallow, provide a sugary drink (like fruit juice or a non-diet soft drink), glucose tablets, or sweets.
3. Monitor and Reassess: Wait 10–15 minutes for the sugar to take effect. If symptoms persist, offer another sugary item.
4. Call Emergency Services: If the person becomes unconscious or unresponsive, place them in the recovery position and call 999 immediately. Do not try to give them food or drink.

First Aid for Hyperglycaemia

1. Recognise the Symptoms: If the person complains of excessive thirst, fatigue, or nausea, suspect high blood sugar.
2. Encourage Fluids: Offer water to prevent dehydration, but avoid sugary drinks.
3. Check for Insulin: If the person is carrying their insulin and is confident in administering it, assist them as necessary. Do not administer insulin yourself unless trained.
4. Monitor the Situation: If symptoms worsen or the person shows signs of diabetic ketoacidosis (e.g., fruity-smelling breath, confusion, rapid breathing), seek medical help immediately.

When to Call Emergency Services

It’s crucial to involve emergency services (999 in the UK) in the following situations:

• The person is unconscious or unresponsive.
• Symptoms persist despite initial first aid measures.
• The person is unable to swallow or ingest sugar.
• They exhibit signs of diabetic ketoacidosis or severe hyperglycaemia.

The Importance of First Aid Training

While this guide provides an overview, comprehensive first aid training can significantly boost your confidence and ability to handle emergencies. Such training equips you with the skills to identify emergencies, provide tailored care, and stay calm under pressure. If you frequently interact with individuals with diabetes, consider enrolling in our 3-Day First Aid at Work course to enhance your knowledge and preparedness.

Being equipped to provide first aid for diabetes-related emergencies can make a significant difference in outcomes. Recognising symptoms early, knowing the appropriate steps to take, and understanding when to escalate to emergency services are critical skills. By spreading awareness and promoting first aid training, we can ensure more people are prepared to offer life-saving assistance when it matters most.

FAQ

What is the first step in assisting someone with low blood sugar?
Offer them a fast-acting source of sugar, such as glucose tablets or a sugary drink, if they are conscious and able to swallow.

Should I give insulin to someone during a diabetic emergency?
No, unless you are trained and the person explicitly asks for assistance. Insulin dosage is highly individualised and incorrect administration can be dangerous.

What should I do if the person is unconscious?
Place them in the recovery position and call 999 immediately. Do not give them food or drink.

Can diabetic emergencies happen to people without a diabetes diagnosis?
Yes, although rare, conditions like hypoglycaemia can occur in non-diabetics due to other health issues. Treat them similarly and seek medical advice.

How can I prevent diabetic emergencies?
For diabetics, maintaining a balanced diet, adhering to medication schedules, and monitoring blood sugar levels are essential. For caregivers, staying informed and attentive to signs of distress is key.
