Abstract
Nausea, vomitus, diarrhea and constipation rank among the most frequent gastrointestinal complications in oncology patients. It is necessary to prevent nausea and vomitus before the therapy administration.
Convenient antiemetics are chosen depending on emetogenic potential of ongoing therapeutic regimen. Main trouble in diarrhea treatment is its various etiology, even sometimes the etiology is multifactorial.
Therefore it is very important to make a good differential diagnosis and to focus on patient s anamnesis: past surgeries, ongoing therapy and patient s regimen and diet. Constipation in oncology patient is very commonly caused by his medication, which is difficult to replace.
Therefore laxatives become the part of the patient s regular farmacotherapy. Key words: constipation, diarrhea, gastrointestinal complications, nausea, vomiting.
