Up to 80% of all critically ill patients develop gastrointestinal dysfunction, predominantly gastrointestinal motility disorder. In critically ill patients, gastrointestinal dysfunction or gastrointestinal failure is associated with increased morbidity and mortality. Correct diagnosis and early start of treatment are essential and can influence the outcome. Therapeutic options are normal potassium and magnesium levels, restrictive fluid balance, improved gastrointestinal microcirculation, individual sedoanalgetic concepts and early enteral nutrition. In addition, numerous target-oriented medical therapeutic options are available.
