Abstract

Elevated levels of gastric inhibitory peptide (GIP) in anorexia nervosa may normalize after short-term weight restoration.

GLP-1 and glicentin levels do not change during the acute state of anorexia nervosa but decrease after short-term weight restoration.
The relationship between these hormone levels and the state of underweight in anorexia nervosa is not fully understood.
Long-term recovery effects on these hormone levels have not been extensively studied.
There is potential for GIP to serve as a marker for the acute state of anorexia nervosa.

Simplified

Glucagon-like peptide-1 (GLP-1), gastric inhibitory peptide (GIP), glucagon, and glicentin are gastrointestinal hormones derived from proglucagon that play crucial roles in regulating appetite and glucose homeostasis. These hormones have been examined during the acute state of anorexia nervosa (AN), with our previous study showing elevated GIP levels in the acute state which normalized following short-term weight restoration. GLP-1 and glicentin concentrations remain unchanged in the acute state, but decrease after short-term weight restoration. However, few studies have investigated whether these alterations are more than mere consequences of the severe underweight, whether they persist after long-term recovery, and whether they could therefore be considered potential trait markers.
