My mother is 45 years old.She recently had an aneurysm surgery,september 13th,her blood pressure is stable,she doesnt have diabetes.1 month back she used to have headaches.Now the headaches arent there,but shes dizzy all the time.She also vomits,once sometimes twice a day.I would like an opinion as to what is the cause for this.
In all likelihood the after effects of anesthesia..... also possible would be swelling in the brain around the area of the surgery.  These symptoms are likely being monitored by nursing and if they reach a certain severity level the surgeon will be notified.  Otherwise, she'll get better in the next 24-48 hrs.  The other possibility is that because of the aneurysm surgery itself there maybe been a bit of a bleed perioperative (during the procedure) or a bit postoperatively (after the surgery) and the expanding lesion or increasing pressure inside the head is causing the nausea/vomiting.  So long as symptoms aren't really marching upward and becoming more intense she should be fine. Please rate this answer with STARS if it was useful to you and I would be very appreciative.
