NAUSEA & VOMITING
Nausea is the sensation felt immediately before vomiting.
Vomiting is a partially voluntary act of forceful expelling of stomach contents up to and out of the mouth that may or may not be preceded by nausea.
Retching or repetitive active contraction of the abdominal muscles occurs between nausea and vomiting.
Management includes correction of clinically relevant metabolic complications, pharmacological therapy and treatment of underlying cause.

Supportive Therapy

  • Other measures to reduce nausea and vomiting may be useful, particularly in patients who have nausea and vomiting of pregnancy:
    • Patients should be advised to increase their rest because tiredness may make nausea worse
    • Advise patients to avoid sensory stimuli that trigger symptoms eg strong odors, noise, flickering lights, heat, humidity
    • Enlist support from patient’s family and friends
  • Acupressure, acupuncture and acustimulation may be beneficial in patients with PONV and in women with nausea and vomiting of pregnancy
