It depends on why you are light headed :) When do you notice it? Does any certain thing bring it on? Have you checked your blood pressure while you are light headed? When was the last time you ate?
Hi
Welcome to the MedHelp forum!
There are many causes of dizziness, lightheadedness, passing out, blackouts etc. It is difficult to comment without examination. You need to get examined to rule out a few things such as low blood pressure, postural hypotension (fall in blood pressure, cervical spinal nerve compression, hypoglycemia (low blood sugar), severe anemia, an underactive thyroid (called hypothyroidism), overactive thyroid (called hyperthyroidism), adrenal insufficiency (called Addison's disease), GERD or gastric reflux, and internal ear infections.
Since I cannot examine you and know other related conditions you may be having, nor is a detailed history possible on net, I have listed the various possibilities that should be looked into. Please consult your PCP for primary examination followed by proper referral.
Take care!
I think the more important question is why are you getting light headed to begin with!? Maybe try eating something or eating something with sugar and see if that helps...
