Nausea and Vomiting
Nausea is an unpleasant sensation of being about to vomit, can occur alone or can accompany vomiting, dyspepsia, or other gastrointestinal symptoms. It is common symptoms in patients receiving palliative care and is associated with substantial physical and psychological distress and worsening of quality of life. In cancer patients, cancer treatments and opioids are the most common causes. Management include supportive measures such as maintaining proper oral hygiene, frequent small volume food and fluid intake at regular intervals, intravenous fluids if appropriate, and discontinuation of unnecessary medications. Specific treatment should target the underlying cause, e.g., aggressive bowel regimen for opioid related constipation, and 5HT3 receptor antagonists for chemotherapy induced nausea.
