E89: Postprocedural endocrine and metabolic disorders, not elsewhere classified

E89.1: Postprocedural hypoinsulinaemia

The sugar level in every person’s blood increases after eating. The pancreas then produces the messenger substance insulin. Insulin ensures that the sugar from the blood is absorbed into the cells. After eating, the pancreas releases insulin into the blood. As a result, the sugar level in the blood drops again for a while after eating.

If there is insufficient insulin, the sugar level in the blood does not decrease properly. In that case, there is too much sugar in the blood. It can also be said that the blood sugar is too high.

In your case, the blood sugar has increased after an examination or treatment. You may have undergone an examination or treatment on your pancreas. It is also possible that you had insufficient insulin in your blood after an operation.
