Insulin injection. She has diabetes mellitus. This is a disorder affecting glucose sugar metabolism, where the sugar is not oxidised due to a lack of the hormone insulin, secreted by the pancreas in healthy individuals. In diabetics, unused sugar accumulates in the blood and the urine. Fats are utilised as an alternative energy source, which leads to a build-up of ketones in the blood that may eventually cause convulsions and diabetic coma. Treatment is based on a strict diet and the use of daily insulin injections to maintain the blood-sugar balance.
