One of the more unpleasant side effects of surgery is nausea.
Several different culprits may be to blame. Low blood pressure, low
blood sugar, or dehydration after surgery can cause lightheadedness,
dizziness and nausea. Intravenous fluids can be given during and after
the procedure to help decrease the risk of these problems.
General anesthesia and sedative medications used during surgery can
cause nausea, as can the narcotic pain medications used during and
after surgery. These effects can usually be combated with anti-nausea
medication. Usually, postoperative nausea and vomiting passes fairly
quickly within the first few hours of the procedure. Patients who have
a history of nausea and vomiting after surgery should talk to their
surgeon and anesthesiologist so the team can be better prepared to
prevent the unpleasant feeling before it starts.
