Gastric dysrhythmia syndrome

Gastric dysrhythmia syndrome refers to a group of symptoms including nausea, vomiting, abdominal pain, and abdominal distension caused by disordered or excessively rapid gastric peristaltic rhythm. This syndrome mostly occurs after abdominal surgery, such as cholecystectomy, hiatal hernia repair, or pyloroplasty, as well as in severe diabetes with extensive autonomic nerve damage. Other studies suggest that an imbalance in the fine ratio between excitatory neurotransmitters (such as acetylcholine, motilin, and gastrin) and inhibitory neurotransmitters (such as norepinephrine, dopamine, vasoactive intestinal peptide, and enkephalins) may lead to gastric dysrhythmia.
