What im seeing here is orthostatic hypotension- read about it- and youll likely to see the symptoms u just mentioned such as dizzy spells upon getting up from the bed. This is caused by a sudden drop in blood pressure after changing body positions. Orthostatic hypotension though is just a symptom and not a disease---- it is however caused by possible underlying diseases/health problems such as anemia, among others.
As always, if you have concerns about your health, especially with signs/symptoms which are so unusual --- go see your doctor. everyone on yahoo answers cannot diagnose and were all taking guesses. good luck with your check-up.
well when you get up from bed and continue to walk, your head is draining the blood that was up there and going back down to your body. It is normal. That is why school nurses always say "dont get up too fast" and "sit 20 sec before walking away" in the morning. drink plenty of water, your body detoxis itself all night and it's best to get all that junk flushed out of your system.dehydration also is an explains the dizziness/lightheaded feeling. I had the exact feeling that you had. Also, if your blood is moving quickly in your neck, it can also be a sign you need excersise. hope this helps.
well this happens to me when i'm DEHYDRATED. So if you haven't been drinking much water lately, drink at least 6 glasses a day.
No one but a physician can tell you what is going on, and not without an examination. Tell your parents that you think you need to see a doctor and make an appointment ASAP.
