When diabetic sugar is low, also known as hypoglycemia, it can be dangerous if not treated quickly. Knowing the symptoms, causes, and what to do can help you stay safe and healthy.
When Diabetic Sugar Is Low: What Happens?
Low blood sugar (hypoglycemia) usually means your glucose level is below 70 mg/dL. This can happen for people with both type 1 and type 2 diabetes. It’s often caused by too much insulin, missing a meal, eating less than usual, or extra physical activity.
Symptoms of Low Blood Sugar in Diabetes
- Shaking or feeling jittery
- Sudden sweating
- Dizziness or lightheadedness
- Hunger
- Confusion or trouble concentrating
- Fast heartbeat
- Irritability or mood changes
- Blurred vision
- Weakness
Severe low blood sugar can cause fainting, seizures, or even a diabetic emergency. Always take symptoms seriously and act quickly.
What To Do When Blood Sugar Is Low for Diabetics
If you notice symptoms, check your blood sugar right away. If it’s below 70 mg/dL, follow the “15-15 Rule”:
- Eat or drink 15 grams of fast-acting carbs (like glucose tablets, 4 oz juice, or regular soda).
- Wait 15 minutes, then recheck your blood sugar.
- If it’s still low, repeat the steps.
Once your sugar returns to normal, eat a small snack if your next meal is more than an hour away. If you lose consciousness or can’t swallow, someone should call 911 immediately.
How To Prevent Low Blood Sugar
- Eat regular meals and snacks.
- Don’t skip meals.
- Monitor your blood glucose often, especially if you’re on insulin.
- Carry a quick sugar source at all times.
- Talk to your doctor about adjusting medications if you have frequent lows.
Why This Matters
Managing low blood sugar is key for safe diabetes care. It helps prevent emergencies and keeps you feeling your best. If you have frequent lows, talk to your healthcare team about your diabetes management plan.
