11 Warning Signs Of Hypoglycemia That You Should Never Ignore


Hypoglycemia, also known as low blood sugar, is something you may have heard of before, but may not know quite exactly what it is. Although it's most common in people with diabetes, it can occur for other reasons as well, and there are distinct warning signs of hypoglycemia that you can look out for. Low blood sugar can cause both short-term and longer-term complications, making it important you know what bodily changes could signify the condition.

"Hypoglycemia typically relates to a blood sugar less than 60 for most people," says Dr. Heather Bartlett over email. "However, some people that are unknown diabetics or are pre-diabetic may be living at a higher blood sugar all the time, above normal, so even a drop to what is considered normal for most people could provoke a symptom of hypoglycemia."

In addition to diabetes, hypoglycemia can be caused by diet, certain medications, hormone or enzyme deficiencies, and more, according to medlineplus.com. Discovering signs of hypoglycemia can help you get treated for any underlying medical issues and prevent further damage.

If you're feeling off and think your blood sugar might be to blame, watch out for these 11 warning signs that could mean you're hypoglycemic.

1. Fatigue


If you feel exceptionally tired all the time, your blood sugar may be to blame. When your blood sugar levels plummet, it leaves you feeling fatigued and sleepy, even throughout the day, according to universityhealthnews.com.

2. Irritability & Anxiety


When not enough glucose crosses the cell membrane of brain cells, it can cause a deterioration in a person's mental status. This could result in severe mood swings or anxiety, or it could even be something as mild as general irritability or feeling easily annoyed, according to everydayhealth.com.

3. Headaches


Headaches from hypoglycemia are usually described as a dull, throbbing feeling in the temples, according to verywell.com. It can also trigger migraines, but instead of being accompanied by the usual nausea, vomiting, and sensitivity to light and sound, these migraines come with other symptoms of hypoglycemia such blurry vision, fatigue, irritability, and confusion.

4. Constant Hunger


Hypoglycemia can make you feel a constant, excessive hunger, according to healthcentral.com. Eating can usually help raise blood sugar, but avoid foods like sugar and carbohydrates that can cause a crash again later on.

5. Heart Palpitations


If you find that your heart is racing more than normal, your blood sugar might be low. Hypoglycemia commonly causes a rapid heartbeat and heart palpitations, according to Healthline.com.

6. Pale Skin

Hypoglycemia can also affect the look of your skin. When your blood sugar drops, your face can become cold and pale, according to everydayhealth.com.

7. Brain Fog


In addition to fatigue and headaches, hypoglycemia can also cause a brain fog. Your brain needs glucose for fuel, so when it lacks energy, it can't perform properly, leaving you feeling dazed and confused, according to Dr. Michael Lam in an article on dr.lam.com.

8. Dizziness


Dizziness and lightheadedness can occur as a result of low blood sugar, according to the NHS. This is often accompanied with feelings of confusion and fatigue, and it could even include disorderly behavior that could be confused with drunkenness.

9. Tingling Sensation Around The Mouth


If your mouth or lips are tingling, you might have hypoglycemia, according to verywell.com. This could also include tongue numbness or metallic taste in the mouth.

10. Sweating


Early warnings of hypoglycemia include unusual sweating that may be later accompanied by chills, according to diabetesselfmanagement.com. It can occur all over the body, not just on the armpits, and it can progress from mild to drenching.

11. Shaking


When your blood sugar drops, you may get some shakiness along with your anxiousness and fast heart rate, according to healthline.com. This could also be accompanied by skin tingling as well.

Whenever you feel any of these symptoms together, it's best to see a doctor to prevent any complications from hypoglycemia.
