Refeeding Syndrome (RFS) is a potential life-threatening complication of the nutritional therapy in the replenishment phase after period of starvation. This not very known syndrome may be a life-threatening metabolic condition due to rapid, inadequate nutritional support in malnourished catabolic patients. The intake of food and therefore the switch from a catabolic to an anabolic metabolism is most considered etiological mechanism.

Lack of vitamins, especially vitamin B1 or thiamine is often present and involves severe clinical complications.
