Predictors of impaired awareness of hypoglycaemia and severe hypoglycaemia in adults with type 1 diabetes.

Diabetic medicine : a journal of the British Diabetic Association·2025

Severe hypoglycemia in adults can stem from hypopituitarism. Undiagnosed growth hormone deficiency significantly impacts glucose metabolism, leading to recurrent hypoglycemia episodes in patients with hypopituitarism.

Area of Science:

  • Endocrinology
  • Metabolic Disorders
  • Neuroendocrinology

Background:

  • Hypoglycaemia is a rare complication of hypopituitarism in non-diabetic adults.
  • A patient with Cushing's disease underwent bilateral adrenalectomy and pituitary radiotherapy.

Observation:

  • The patient experienced recurrent seizures and symptoms of spontaneous hypoglycaemia 20 years post-treatment.
  • Glucocorticoid replacement therapy adjustments did not resolve the hypoglycaemic episodes.

Findings:

  • Severe hypoglycaemia resolved following the diagnosis and treatment of growth hormone deficiency.
  • Growth hormone deficiency was identified as the cause of persistent hypoglycaemia.

Implications:

  • Undiagnosed growth hormone deficiency in hypopituitarism patients can impair glucose metabolism.
