Low Blood Sugar (Hypoglycemia): Key Signs and Symptoms to Watch For 🩸
Low blood sugar, or hypoglycemia, is a health concern that can happen to anyone, but it’s especially common among people with diabetes. Recognizing the signs and symptoms early can prevent serious complications and help you respond quickly. Here’s a detailed guide to understanding what low blood sugar looks and feels like, along with practical advice on what actions to take.
What Is Low Blood Sugar? 🤔
Low blood sugar means there’s not enough glucose in your bloodstream to fuel your body’s needs—usually defined as a level below 70 mg/dL (3.9 mmol/L). Glucose is the body’s main energy source, and your brain relies on it to function properly. If levels drop too low, your body and mind can’t work as they should.
What Causes Low Blood Sugar? 🦠
Common reasons for hypoglycemia include:
- Too much insulin or diabetes medication
- Skipping or delaying meals
- More physical activity than usual, without extra carbs
- Drinking alcohol (especially on an empty stomach)
- Certain illnesses or health conditions
