E90: Nutritional and metabolic disorders in diseases classified elsewhere

The body produces energy from food. Furthermore, the body makes construction material from food, for instance to repair or construct tissue. This is also called metabolism. The metabolism is influenced by various messenger substances. The messenger substances in the body control hunger, the sugar level in the blood and digestion, for example.

You may not be able to tolerate certain foods. Or you may not be consuming enough energy overall with your food. Your nutrition or messenger substances are abnormal due to another disease.
