Hyperalimentation refers to a state where quantities of food consumed are greater than appropriate.[1] It includes overeating, as well as other routes of administration such as in parenteral nutrition.

The term can also be used to describe ingestion to compensate for past deficiencies.[2] In this context, it can refer to parenteral nutrition, though this has been described as incorrect.[1]

It is a frequent iatrogenic cause of normal anion gap acidosis, a subset of metabolic acidosis.

Hyperalimentation can also cause an osmotic diuresis due to an increased load of urea from protein catabolism. Frequently, it is also associated with opportunistic infections by Candida albicans.
