[An unusual case of prolonged hypoglycemia]

The author described a case of protracted hypoglycaemia in a young type I insulin treated diabetic, associated at first with neurological symptomatology imitating a cerebrovascular attack. After three days, when it was necessary to administer repeatedly glucose by the i.v. route on account of low blood sugar levels, the carbohydrate metabolism deteriorated and called for administration of similar insulin doses as before. In the discussion the author deals with pathogenetic possibilities of the described condition.
