What Causes Low Blood Sugar If You''re Not Diabetic?

Non-diabetic hypoglycemia can result from several underlying causes that affect blood sugar regulation. Reactive hypoglycemia occurs 2-4 hours after eating, triggered by excessive insulin release in response to certain foods, particularly refined carbohydrates. Medical conditions like insulinomas (insulin-producing tumors), adrenal insufficiency, or severe liver disease can cause persistent low blood sugar. Medications including beta-blockers, quinine, and excessive alcohol consumption can also trigger hypoglycemic episodes. Prolonged fasting, intense exercise without adequate fuel, or gastric bypass surgery may lead to blood sugar drops below 70 mg/dL, causing symptoms like shakiness, sweating, and confusion.
