Emergency Diabetes Care: What to Do When Blood Sugar Spikes or Drops Dangerously

When someone with diabetes faces a sudden emergency diabetes care, a life-threatening situation caused by dangerously low or high blood sugar levels that requires immediate action. Also known as diabetic emergency, it can happen to anyone—even those who manage their condition well. It doesn’t wait for office hours. It doesn’t care if you’re at work, driving, or asleep. That’s why knowing the signs and acting fast can mean the difference between recovery and hospitalization.

Low blood sugar, a condition where glucose drops below 70 mg/dL, often due to too much insulin, skipped meals, or intense exercise. Also known as hypoglycemia, it shows up as shaking, sweating, confusion, or sudden dizziness. If ignored, it can lead to seizures or unconsciousness. Quick fix? 15 grams of fast-acting sugar—glucose tablets, juice, or candy. Wait 15 minutes. Check again. Repeat if needed. Never give insulin when blood sugar is low. That’s a deadly mistake.

High blood sugar, a dangerous rise in glucose, often from missed medication, illness, or too many carbs. Also known as hyperglycemia, it builds slowly but can turn into diabetic ketoacidosis (DKA), especially in type 1 diabetes. Signs include extreme thirst, frequent urination, nausea, fruity-smelling breath, and confusion. DKA is an emergency. It needs insulin and fluids—fast. Home remedies won’t cut it. Call 911 or head to the ER. Don’t wait for it to get worse.

People with diabetes aren’t alone in this. Family, coworkers, teachers—all need to know the basics. A glucose meter, glucagon kit, and medical ID bracelet aren’t optional. They’re lifelines. And if you’re caring for someone with diabetes, learn how to use a glucagon injection. It’s simple. It’s safe. It can save a life.
