🩸 Diabetes Education Series – Episode 9
Low Blood Sugar (Hypoglycemia)
Low blood sugar, also called hypoglycemia, occurs when your blood glucose level drops below 70 mg/dL (3.9 mmol/L). It is most common in people taking insulin or certain diabetes medications, but it can occasionally occur in people without diabetes.
Your brain depends on glucose as its main source of energy. When blood sugar drops too low, your body quickly releases stress hormones to raise it, causing early warning symptoms. If blood sugar continues to fall, it can affect brain function and become a medical emergency.

⚠️ Common Causes
Low blood sugar can happen for several reasons, including:
💉 Taking too much insulin or diabetes medication
🍽️ Skipping or delaying meals
🥖 Not eating enough carbohydrates
🏃 Exercising more than usual without eating enough beforehand
🍷 Drinking alcohol, especially on an empty stomach
🤒 Vomiting or diarrhea that prevents you from keeping food down
⏰ Taking insulin but eating much later than planned

🚑 Emergency Treatment (The 15-15 Rule)
If you are awake and able to swallow:
Step 1
Check your blood sugar if possible.
If it is below 70 mg/dL, treat immediately.
Step 2
Consume 15 grams of fast-acting carbohydrates, such as:
🥤 ½ cup (120 mL) fruit juice
🥤 ½ cup regular (non-diet) soda
🍬 3–4 glucose tablets (follow the package directions)
🍯 1 tablespoon of honey or sugar (only if the person is awake and can swallow safely)
Step 3
Wait 15 minutes.
Step 4
Recheck your blood sugar.
If it is still below 70 mg/dL, repeat the treatment.
Step 5
Once your blood sugar returns to normal, eat a small snack or meal containing carbohydrates and protein if your next meal is more than an hour away. This helps prevent your blood sugar from dropping again.

🚨 When to Call 911
Call emergency services immediately if the person:
❌ Is unconscious
❌ Is having a seizure
❌ Cannot safely swallow food or drinks
❌ Does not improve after repeated treatment
Do not give food, drinks, or honey to someone who is unconscious or unable to swallow, as this can cause choking.
If a glucagon emergency kit or glucagon nasal powder has been prescribed, use it according to the instructions while waiting for emergency medical help.

❤️ The Bottom Line
Low blood sugar can develop quickly and should never be ignored. Learning to recognize the early warning signs and treating hypoglycemia promptly can prevent serious complications.
If you have diabetes, always carry a source of fast-acting carbohydrates, wear medical identification if recommended, and let family, friends, and coworkers know how to help in case of an emergency.
