How to Assist a Diabetic Emergency: A Definitive Guide

A diabetic emergency can be a frightening and critical situation, not only for the individual experiencing it but also for those around them. Understanding how to react swiftly and effectively can literally save a life. This comprehensive guide will equip you with the knowledge and actionable steps needed to confidently assist someone undergoing a diabetic crisis, focusing on both high blood sugar (hyperglycemia) and low blood sugar (hypoglycemia). We’ll delve into recognizing the signs, administering appropriate first aid, and knowing when to seek professional medical help.

Understanding Diabetes and Its Emergencies

Before diving into emergency protocols, it’s crucial to grasp the basics of diabetes. Diabetes mellitus is a chronic condition characterized by elevated levels of glucose (sugar) in the blood. This occurs either because the body doesn’t produce enough insulin (Type 1 diabetes), or because it can’t effectively use the insulin it produces (Type 2 diabetes). Insulin is a hormone that acts like a key, allowing glucose to enter cells for energy. Without proper insulin function, glucose builds up in the bloodstream, leading to various health complications.

Diabetic emergencies primarily fall into two categories:

Hypoglycemia (Low Blood Sugar): This is often more immediately dangerous as the brain relies heavily on glucose for fuel. Without sufficient glucose, brain function can rapidly deteriorate, leading to confusion, seizures, unconsciousness, and even death if not promptly treated.
Hyperglycemia (High Blood Sugar): While less immediately life-threatening than severe hypoglycemia, prolonged and severe hyperglycemia can lead to serious conditions like Diabetic Ketoacidosis (DKA) in Type 1 diabetics or Hyperosmolar Hyperglycemic State (HHS) in Type 2 diabetics. Both DKA and HHS are medical emergencies requiring urgent professional intervention.

Recognizing the distinct signs and symptoms of each is the first crucial step in providing effective assistance.

Recognizing the Signs: Hypoglycemia vs. Hyperglycemia

Accurate identification of the type of diabetic emergency is paramount, as the treatment for low blood sugar is diametrically opposed to that for high blood sugar. Administering the wrong treatment can have severe consequences.

Hypoglycemia: The Fast and Furious Onset

Hypoglycemia typically develops rapidly, often within minutes. Its symptoms are often categorized as adrenergic (due to adrenaline release) and neuroglycopenic (due to glucose deprivation in the brain).

Common Symptoms of Mild to Moderate Hypoglycemia:

Sudden onset of sweating: The skin may feel clammy.
Trembling or shakiness: A noticeable tremor in the hands or body.
Rapid heartbeat (tachycardia) or palpitations: The person may complain of their heart racing.
Extreme hunger: A sudden and intense craving for food.
Nervousness or anxiety: Appearing agitated or restless without clear reason.
Dizziness or lightheadedness: Feeling faint or unsteady.
Irritability or mood changes: Uncharacteristic anger, sadness, or confusion.
Pale skin: A noticeable paleness to the complexion.
Headache: A dull ache or throbbing sensation.

Common Symptoms of Severe Hypoglycemia (Neuroglycopenic):

Confusion and disorientation: Inability to think clearly, answer questions, or remember recent events. They may seem intoxicated.
Slurred speech: Difficulty articulating words, similar to someone who has consumed alcohol.
Blurred or double vision: Difficulty focusing their eyes.
Lack of coordination or clumsiness: Stumbling, dropping things, or difficulty with fine motor skills.
Difficulty waking up from sleep: If they are asleep, they may be unusually difficult to rouse.
Loss of consciousness (unresponsiveness): The person may pass out.
Seizures: Uncontrolled muscle contractions.
Coma: A deep state of prolonged unconsciousness.

Example: Imagine you’re having coffee with a friend who has Type 1 diabetes. Suddenly, they start sweating profusely, their hands begin to tremble uncontrollably, and they become unusually irritable, snapping at a waiter for a minor delay. They might then complain of feeling dizzy and intensely hungry. These are classic early signs of hypoglycemia.

Hyperglycemia: The Gradual Accumulation

Hyperglycemia develops much more slowly, often over hours or even days, as blood sugar levels steadily climb. The body attempts to compensate, leading to a cascade of symptoms.

Common Symptoms of Hyperglycemia:

Frequent urination (polyuria): The kidneys try to excrete excess glucose, leading to increased urine production.
Increased thirst (polydipsia): Due to fluid loss from increased urination, the body becomes dehydrated.
Extreme hunger (polyphagia): Despite high blood sugar, cells are starved of glucose, triggering hunger signals.
Fatigue or weakness: Lack of cellular energy.
Blurred vision: High sugar levels can affect the lenses of the eyes.
Numbness or tingling in hands or feet: Neuropathic symptoms, though typically associated with long-term uncontrolled diabetes, can worsen acutely.
Slow-healing sores or frequent infections: Impaired immune function due to high sugar.

Symptoms of Severe Hyperglycemia (DKA or HHS – Medical Emergencies):

Fruity-smelling breath (DKA only): A distinct sweet or acetone-like odor, similar to nail polish remover. This is a critical sign of DKA.
Nausea and vomiting: The body’s attempt to rid itself of toxins.
Abdominal pain: Often severe in DKA.
Rapid, deep breathing (Kussmaul respirations – DKA only): The body’s attempt to expel excess carbon dioxide and acidosis.
Dry mouth and very dry skin: Severe dehydration.
Flushed face: Due to dehydration and increased blood flow.
Confusion, disorientation, or difficulty concentrating: Brain affected by electrolyte imbalance and dehydration.
Loss of consciousness or coma: In severe, untreated cases.

Example: Your elderly neighbor, who has Type 2 diabetes, hasn’t been feeling well for a few days. You notice they’re making frequent trips to the bathroom, seem unusually thirsty, and are much more tired than usual. They might mention that their vision seems blurry. While not as dramatic as a hypoglycemic event, these are red flags for potential hyperglycemia that could escalate into DKA or HHS if not addressed. If you then notice a sweet, fruity smell on their breath and they complain of severe stomach pain, immediate medical attention is required.

Immediate Action: The First Aid Protocols

Once you suspect a diabetic emergency, your immediate actions are critical. Always prioritize safety for both yourself and the person in distress.

Assisting Hypoglycemia: Glucose is Key!

This is the more common and rapidly dangerous emergency. Your goal is to get fast-acting glucose into the person’s system as quickly as possible.

Step 1: Assess Responsiveness and Safety.

Is the person conscious and able to swallow? This is the most important distinction.
Are they in a safe environment? If they are dizzy or disoriented, help them sit or lie down to prevent falls.
Do not leave them alone.

Step 2: Administer Fast-Acting Carbohydrates (If Conscious and Able to Swallow).

The “Rule of 15”: Give 15 grams of a fast-acting carbohydrate. Wait 15 minutes, recheck symptoms (if possible, blood sugar), and if still low or symptoms persist, repeat another 15 grams.
Examples of 15 grams of fast-acting carbohydrates:
- 4 glucose tablets (check label for exact dosage)
- 1/2 cup (4 ounces) fruit juice (orange, apple, grape)
- 1/2 can (4 ounces) regular soda (NOT diet soda)
- 1 tablespoon of honey or corn syrup (rubbed on the inside of the cheek if they struggle to swallow)
- 5-6 hard candies (like lifesavers, not chocolate)
- Gel tube specifically designed for hypoglycemia.
Concrete Example: Your colleague suddenly feels shaky and disoriented. They tell you they feel “weird.” Ask them, “Do you have your glucose tablets?” If not, quickly grab a regular soda from the vending machine or offer them a small glass of orange juice from the office fridge. Encourage them to drink it slowly.

Step 3: Monitor and Reassess.

Stay with the person. After 15 minutes, ask them how they feel. Do their symptoms seem to be improving?
If they have a blood glucose meter and are capable, encourage them to check their blood sugar. If it’s still below 70 mg/dL (3.9 mmol/L) or their symptoms haven’t resolved, repeat the 15 grams of fast-acting carbohydrate.
Once their blood sugar is stable and symptoms have resolved, encourage them to eat a small snack containing both carbohydrates and protein (e.g., crackers and cheese, a peanut butter sandwich, a small meal) to help prevent another drop.

Step 4: If Unconscious or Unable to Swallow (Medical Emergency!).

Call emergency services immediately (e.g., 911, 115). State clearly that you suspect a diabetic emergency and the person is unconscious.
Do NOT attempt to give them food or drink by mouth. They could choke.
Check for a medical ID. Look for a medical alert bracelet, necklace, or wallet card that might indicate they have diabetes. This information is crucial for paramedics.
Administer Glucagon if Available and You Are Trained. Glucagon is a hormone that raises blood sugar. Many people with Type 1 diabetes and some with Type 2 are prescribed emergency glucagon kits. It’s usually given as an injection, similar to an EpiPen.
- How to administer Glucagon: Read the instructions on the kit carefully. It typically involves mixing a powder with a liquid and injecting it into a large muscle (like the thigh or arm). Even if you’re unsure, emergency dispatchers can guide you.
- Important: Glucagon can cause nausea and vomiting after administration. Once the person regains consciousness, roll them onto their side (recovery position) to prevent aspiration if they vomit.
Stay with the person. Continue to monitor their breathing and consciousness until medical help arrives. If they stop breathing, begin CPR if you are trained.

Example: You find your neighbor, who you know has diabetes, unresponsive on their living room floor. You immediately call 911. While on the phone, you quickly check their wrist for a medical ID bracelet. You find a glucagon kit on their coffee table. Following the dispatcher’s instructions, you prepare and inject the glucagon into their thigh. You then carefully turn them onto their side, maintaining an open airway, until paramedics arrive.

Assisting Hyperglycemia: Support and Medical Alert

While not as immediate as severe hypoglycemia, hyperglycemia requires careful monitoring and often professional medical intervention. Your role here is more about support and ensuring timely medical evaluation.

Step 1: Assess the Situation.

Is the person conscious and coherent?
Are they exhibiting signs of DKA or HHS (fruity breath, deep breathing, severe abdominal pain, confusion)? If so, this is a medical emergency.

Step 2: Encourage Hydration (If Conscious and Able to Drink).

Offer sips of water or sugar-free fluids. Dehydration is a major concern with hyperglycemia.
Do NOT give them sugary drinks.
Concrete Example: Your colleague has been complaining of excessive thirst and frequent urination for a few days. You notice they seem very tired. Offer them a bottle of water and encourage them to drink it.

Step 3: Encourage Insulin Administration (If They Have It and Are Able).

If the person has diabetes and carries insulin, gently ask if they have taken their insulin or if they need help administering it. Many people with diabetes have specific protocols for high blood sugar (e.g., correction doses).
Never administer insulin yourself unless you are a trained medical professional or explicitly instructed by the person or emergency services and confident in doing so. A mistake could lead to dangerous hypoglycemia.

Step 4: Monitor and Seek Medical Advice/Help.

If symptoms are mild and the person is managing their condition, encourage them to check their blood sugar and follow their doctor’s instructions. They may need to adjust their insulin or medication.
Call their doctor or healthcare provider for advice if they are feeling unwell or their blood sugar is persistently high.
Call emergency services immediately (e.g., 911, 115) if you observe any signs of severe hyperglycemia (DKA/HHS):
- Fruity breath
- Nausea and vomiting
- Severe abdominal pain
- Rapid, deep breathing (Kussmaul respirations)
- Confusion, disorientation, or slurred speech
- Loss of consciousness
Concrete Example: You notice your friend, who has Type 2 diabetes, is unusually lethargic and her breath has a faint, sweet smell. She complains of stomach pain. Immediately, you call 911 and describe her symptoms. While waiting, you help her sit comfortably and offer her sips of water, but nothing else.

What to Communicate to Emergency Responders

When emergency services arrive, clear and concise communication is vital. Be prepared to provide the following information:

Your location: Exact address, apartment number, cross streets, and any relevant directions.
What happened: Briefly describe the situation and the person’s symptoms.
Type of emergency suspected: “I suspect a diabetic emergency, possibly low blood sugar, and they are unconscious,” or “I suspect high blood sugar, and they have fruity breath.”
The person’s known medical history: Do they have Type 1 or Type 2 diabetes? Any other conditions?
Medications: Do they take insulin, oral medications, or other drugs?
What you have already done: “I gave them orange juice,” or “I administered glucagon.”
Last known blood sugar reading (if available).
Any medical alert identification.

Example: When paramedics arrive, you calmly state, “My friend, Sarah, who has Type 1 diabetes, suddenly became confused and then lost consciousness. Her hands were trembling, and she was very sweaty. I found her glucagon kit and administered it about five minutes ago. She’s starting to stir now. She takes Novolog and Lantus insulin.” This provides a complete and actionable picture.

Prevention and Preparedness: Being a Proactive Assistant

While emergencies are unpredictable, a degree of preparedness can make a world of difference.

For Individuals with Diabetes:

Wear a medical alert ID: A bracelet or necklace that clearly states “DIABETES” and whether it’s Type 1 or Type 2 can save precious time in an emergency.
Carry emergency supplies: Always have fast-acting carbohydrates (glucose tablets, gel, or hard candies) readily available. If prescribed, carry your glucagon kit and ensure it’s not expired.
Educate friends, family, and colleagues: Share information about your condition, common symptoms of high and low blood sugar, and what to do in an emergency. Show them where you keep your emergency supplies.
Have an emergency plan: Discuss with your doctor what to do if you experience severe high or low blood sugar.
Keep an up-to-date medication list: Include dosages and frequency.
Regularly check blood sugar levels: This helps prevent emergencies by allowing for timely adjustments.

For Those Assisting:

Learn about diabetes: Understanding the basics empowers you to recognize and respond.
Know who in your circle has diabetes: Be aware of their condition and potential needs.
Ask about their emergency plan: If you spend significant time with someone with diabetes, respectfully ask them about their emergency protocols and where they keep their supplies.
Consider taking a first aid course: Knowing general first aid and CPR is beneficial for any emergency.
Have emergency numbers readily available: Not just 911, but also the person’s emergency contacts.
Familiarize yourself with glucagon: If someone you regularly interact with has a glucagon kit, ask them to show you how to use it. Many diabetes educators offer training.

Concrete Example: You live with a family member who has Type 1 diabetes. You’ve gone with them to their doctor’s appointments and learned about the signs of low blood sugar. They’ve shown you exactly where their emergency glucagon kit is stored in the kitchen and demonstrated how to use it. You also know they prefer orange juice for mild lows. This proactive knowledge makes you a highly effective first responder in an emergency.

Common Pitfalls and Misconceptions to Avoid

Even with the best intentions, certain mistakes can worsen a diabetic emergency.

Do NOT give an unconscious person anything by mouth. This is the most critical rule. Choking and aspiration are serious risks.
Do NOT assume all diabetic emergencies are the same. Hypoglycemia and hyperglycemia require different approaches. If unsure, treat for hypoglycemia first (if conscious), but if unconscious, call 911 immediately.
Do NOT use diet soda or sugar-free products for low blood sugar. These contain artificial sweeteners and will not raise blood glucose.
Do NOT leave the person alone. They need continuous monitoring.
Do NOT try to administer insulin yourself unless specifically trained and the situation warrants it (e.g., as guided by emergency services for a known high blood sugar in a conscious, cooperative individual, which is rare for first responders). The risk of causing a severe low is too high.
Do NOT delay calling for professional medical help if the situation is severe or you are unsure. When in doubt, call 911/115.

When to Call Emergency Services (911/115)

Always err on the side of caution. Call emergency services immediately if:

The person is unconscious or unresponsive.
The person is having a seizure.
The person is unable to swallow.
You administer glucagon, and they do not improve within 10-15 minutes, or you are unsure if they received the full dose.
You suspect severe hyperglycemia (DKA/HHS) with symptoms like fruity breath, deep/labored breathing, severe abdominal pain, persistent vomiting, or increasing confusion.
The person’s blood sugar remains dangerously low despite repeated treatment (e.g., after two or three rounds of 15-gram carbohydrate treatment).
You are unsure what to do, or the situation feels beyond your capability.

The Aftermath: What Happens Next

Once medical professionals take over, your role shifts to providing support and information.

Cooperate fully: Answer any questions paramedics or doctors have.
Provide context: If you know what led to the emergency (e.g., missed meal, new medication, illness), share this information.
Support the individual: Offer comfort and reassurance as they recover.
Encourage follow-up: Ensure the person sees their doctor after an emergency to review their diabetes management plan and prevent future occurrences.
