Signs That You Have Low Blood Sugar (Hypoglycemia)

Summary

Hypoglycemia, or low blood sugar, is a critical health condition that can be life-threatening. It typically presents with a blood glucose level below 50 mg/dL, though symptoms may vary. Common causes include medication overdose, especially of anti-diabetic drugs, infections, alcohol consumption, dietary changes, metabolic disorders, and insulin-secreting tumors. Symptoms range from altered mental status to dizziness and blurred vision, and it's often seen in diabetic patients.

Takeaways

• 🔍 Low blood sugar, also known as hypoglycemia, is a condition characterized by reduced blood glucose levels.
• 📉 Normal fasting blood glucose levels range between 70 to 100 milligrams per deciliter.
• ⚠️ A plasma glucose level below 50 milligrams per deciliter is considered the threshold for hypoglycemia.
• 🚨 Hypoglycemia can be extremely fatal and may lead to death if not promptly addressed.
• 💊 Causes of hypoglycemia include medication overdose, particularly anti-diabetic medications like insulin.
• 🍻 Other causes include infections, alcohol intake, dietary changes, metabolic changes, and activity changes.
• 🍽️ Prolonged fasting and insulin-secreting tumors, such as insulinomas, can also cause hypoglycemia.
• 🏥 Gastrointestinal problems, bariatric surgery, and liver disease are additional causes.
• ❓ In some cases, there is no identifiable cause for hypoglycemia.
• 🩺 Common signs and symptoms of hypoglycemia include altered mental status, headache, anxiety, nausea, fatigue, sweating, increased heart rate, extreme hunger, dizziness, decreased concentration, and blurred vision.

Hypoglycemia is most often seen in diabetic patients.

What are some major causes of hypoglycemia?

Major causes of hypoglycemia include medication overdose (especially anti-diabetic medications such as insulin), infections, alcohol intake, dietary changes that restrict glucose intake, metabolic changes, activity changes, prolonged fasting, insulin-secreting tumors (such as insulinomas), gastrointestinal problems, bariatric surgery, and liver disease.

Can hypoglycemia occur without an identifiable cause?

Yes, in some cases, there is no identifiable cause for hypoglycemia.

What are some common signs and symptoms of hypoglycemia?
