i have had dizzy spells for the last couple of years. Mainly when I first stand up it happens with a minute of walking. My vision starts to go out even with my eyes open I cant see. I just black out. My whole body goes numb including my throat. My hands some times rock back and forth.I have passed out from it before. Im alittle confused at first when it happens but I still remember everything when it happens. I just cant see anything or talk. Ive learned how to deal with this. But it seems like its getting worse. Im doing it several times a day now. Its a scary feeling. Some times its mild and other times its all I can do to lower my self to the ground so I dont fall. Everyone I have talked to about this says its because I have low blood pressure. Im not on any medication. And have no known medical conditions. I am an active mother of four. Im just wanted to know what this is why it happens and what I can do to prevent it from happening or at least control it better. And if there is anything I can do in my life style to either make it stop or at least control it better. Any advice would be appreciated thank you.Josie Gaunt

Hello, Thanks for the query to Chat Doctor. Forum. I would come up with these possibilities for such type of symptoms, This includes.1 Postural hypotension, diagnosis can be confirmed by physical examination at the time of episode.2 Hypertension, diagnosis can be confirmed by physical examination.3 Anemia, diagnosis can be confirmed by examination of blood for hemoglobin level .4 Diabetes, diagnosis can be confirmed by blood sugar examination. In my opinion don't trust peoples, rather consult a physician and get his opinion as physical examination is very important in this type of cases.
