E64.0: Sequelae of protein-energy malnutrition

In the past you were lacking nourishment or certain nutrients. As a result, you are having symptoms.

Your body needs food in order to have enough energy, grow and stay healthy. Food is made up of various nutrients. For example, the body needs proteins to build muscle so that certain processes in the body can occur.

When you do not get enough nourishment or nutrients, various problems can occur. For example, you may lose weight and get thin. Some of the problems may also occur when you once more get enough nourishment and nutrients.

There can be various reasons why there is a temporary lack of nourishment or certain nutrients. For example, you may not have eaten enough for a certain time. It is also possible that, due to some other condition, you were temporarily unable to properly absorb nourishment or nutrients. It is also possible that you temporarily needed more nourishment than normal due to some condition.
