Gastric carcinoma may rarely be the cause of tumour-associated hypoglycaemia. We report the case of an elderly woman who presented in hypoglycaemic coma, and who was found subsequently to have an adenocarcinoma of the stomach. Hypoglycaemia persisted despite prednisolone, diazoxide, and a high concentration dextrose infusion. The few published cases are reviewed in which an association was established between gastric carcinoma and hypoglycaemia, and the possible aetiology of the hypoglycaemia is discussed.
