🔍 What Is Hypoglycemia?
Hypoglycemia refers to a condition where blood glucose levels fall below normal, typically below 70 mg/dL (3.9 mmol/L). It is most commonly seen in people with diabetes, especially those taking insulin or other glucose-lowering medications. However, it can also occur in individuals without diabetes under certain conditions.
⚠️ Why Is Hypoglycemia Important?
Low blood sugar can be dangerous and, if left untreated, may lead to:
- Confusion
- Loss of consciousness
- Seizures
- Coma
In extreme cases, severe hypoglycemia can be life-threatening.
🧠 Common Causes of Hypoglycemia
In People With Diabetes:
- Too much insulin or diabetes medication
- Skipping meals or eating too little
- Increased physical activity
- Alcohol intake on an empty stomach
In People Without Diabetes:
- Fasting or malnutrition
- Hormonal imbalances
- Liver or kidney disorders
- Insulinoma (a rare insulin-producing tumor)
📋 Signs and Symptoms of Hypoglycemia
Recognizing hypoglycemia early is crucial. Symptoms may include:
Early Symptoms | Severe Symptoms |
---|---|
Shakiness or trembling | Confusion or drowsiness |
Sweating | Slurred speech |
Hunger | Blurred vision |
Dizziness or light-headedness | Seizures |
Rapid heartbeat | Unconsciousness |
Anxiety or irritability | Coma (in rare cases) |
Pro tip: Everyone experiences symptoms differently. People with long-standing diabetes may not feel early symptoms — a condition called hypoglycemia unawareness.
🩹 Immediate Treatment of Hypoglycemia
Follow the “15-15 Rule”:
- Eat or drink 15 grams of fast-acting carbohydrates (e.g., glucose tablets, 4 ounces of juice, or 1 tablespoon of honey).
- Wait 15 minutes, then recheck your blood glucose.
- If still below 70 mg/dL, repeat the steps.
Important: If the person becomes unconscious, do not give food or drink. Call emergency medical services and use a glucagon injection if available.
🧬 Diagnosing Hypoglycemia in Non-Diabetics
Doctors often use Whipple’s Triad:
- Signs and symptoms of low blood sugar
- A measured low blood glucose level
- Relief of symptoms when glucose level is raised
Tests may include:
- Fasting blood sugar tests
- Insulin levels
- Imaging for insulinomas
🛡️ How to Prevent Hypoglycemia
For Diabetics:
- Eat regular, balanced meals
- Monitor blood sugar regularly
- Adjust insulin or medication before exercising
- Avoid alcohol on an empty stomach
- Keep glucose tablets or snacks handy
For Non-Diabetics:
- Avoid skipping meals
- Seek medical evaluation if recurrent symptoms occur
- Manage underlying conditions effectively
🏥 When to See a Doctor
Consult your doctor if:
- You have frequent episodes of hypoglycemia
- Your symptoms become severe or unusual
- You have hypoglycemia unawareness
- You’re not diabetic and experience low blood sugar frequently
🧠 Long-Term Risks of Hypoglycemia
Repeated or severe episodes of hypoglycemia may lead to:
- Cognitive decline, especially in older adults
- Poor diabetes control due to fear of low blood sugar
- Increased risk of accidents and falls
