HI, thanks for using healthcare magic
You may need to have your blood pressure and pulse checked in a sitting then standing position to see if there is any significant change.
Some persons may have a drop in blood pressure that causes symptoms on standing.
The causes for persistent
vomiting include: (1)infection--kidneys, liver
(2)side effect of medication
(3)high levels of calcium
(4)kidney failure
(5)alcohol use
(6)GERD- reflux
(7)mass in the liver
(8)lesion in the brain
(9)meniere's disease which is a condition involving the ears, not lifethreatening
You may want to consider seeing
neurologist (doctor specializing in nerve disease), to find the cause of the
dizziness,
headaches and
nausea.
Treatment would depend on the cause found.
I hope this helps
