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
- π Low blood sugar, also known as hypoglycemia, is a condition characterized by reduced blood glucose levels.
- π Normal fasting blood glucose levels range between 70 to 100 milligrams per deciliter.
- β οΈ A plasma glucose level below 50 milligrams per deciliter is considered the threshold for hypoglycemia.
- π¨ Hypoglycemia can be extremely fatal and may lead to death if not promptly addressed.
- π Causes of hypoglycemia include medication overdose, particularly anti-diabetic medications like insulin.
- π» Other causes include infections, alcohol intake, dietary changes, metabolic changes, and activity changes.
- π½οΈ Prolonged fasting and insulin-secreting tumors, such as insulinomas, can also cause hypoglycemia.
- π₯ Gastrointestinal problems, bariatric surgery, and liver disease are additional causes.
- β In some cases, there is no identifiable cause for hypoglycemia.
- π©Ί 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.
