From the Research

Non-diabetic hypoglycemia can be caused by several factors including medications, alcohol consumption, critical illness, hormone deficiencies, and certain tumors, as highlighted in a recent study 1 that discussed the successful treatment of refractory hypoglycemia with octreotide in a patient with hepatocellular carcinoma. The causes of hypoglycemia in non-diabetic patients are diverse and can be attributed to various factors. Some of the key causes include:

  • Medications such as insulin (taken by non-diabetics), quinine, salicylates, sulfonamides, and pentamidine, which can lower blood glucose levels
  • Excessive alcohol consumption, which can inhibit gluconeogenesis in the liver, leading to hypoglycemia
  • Critical illnesses such as severe liver disease, kidney failure, sepsis, and starvation, which can disrupt glucose regulation
  • Hormone deficiencies, including adrenal insufficiency, hypopituitarism, and growth hormone deficiency, which can affect glucose metabolism
  • Certain tumors, such as insulinomas (insulin-producing tumors) and other tumors that secrete insulin-like growth factors, which can cause hypoglycemia
  • Reactive hypoglycemia, which can occur after meals due to excessive insulin secretion
  • Genetic disorders affecting carbohydrate metabolism, such as glycogen storage diseases, which can lead to hypoglycemia Treatment of non-diabetic hypoglycemia depends on the underlying cause, but may include dietary changes, addressing the primary condition, or in some cases, medications like diazoxide or octreotide to manage insulin secretion, as discussed in a study on the use of octreotide for hypoglycemia caused by sulfonylurea and DPP-4 inhibitor 2. It is essential to identify and address the underlying cause of hypoglycemia to prevent recurrent episodes and improve patient outcomes, as emphasized in a review on hypoglycemia in diabetes 3.
