Feeling Faint??

your just getting up too fast
Takes me a few seconds to get my vision clear if I jump up too fast

Could be that you are getting up too fast, but if it happens any other time it could also be low blood sugar. Try eating an orange and that might help. Also make sure you are not exercising too hard and not eating enough calories

Could be a number of things. If it's a relatively new occurrence it could be an inner ear inflammation, or it could be that your blood pressure is on the low side.

i get this too ,not just when i get up too quick ,but sometimes during a normal day ,my eyesight goes funny & can feel the colour drain from my face & feels like im going to pass out ,also get shakey with it ,worst time is when it happens in the supermarket at the checkout ,cant tell you what it is but just wanted to tell you i get it too x

I have blood pressure on the low end of normal, and that's fairly typical for me. Doctor said nothing to worry about. My husband has had three attack of passing out and hitting his head after watching a movie (so being sat or laid down for a long time somewhere warm) and then getting up too quickly!

Get yourself checked out, try and balance your blood sugar levels through the day, and get up slower.

This is not normal, you need to see your doctor.
No one on a forum knows enough about you or your medical history to be able to pick what is going on.
There's a very good chance that it's not anything to worry about, but without seeing your doctor you don't know that.

Found this info in an article - a description of lightheadedness (here is the link with the full text: http://www.pneuro.com/publications/dizzy/):
***
This is what you feel when you get up too fast, as if not enough blood is getting to your brain. A certain small amount of transient lightheadedness is normal, but sometimes lightheadedness is more persistent. This occurs with anemia from blood loss, volume loss from sweating, when you are short on fluids. Medicines that affect blood pressure regulation include antihypertensives, diuretics and antidepressants.

My BP is naturally on the lower end of the normal range and I always need to be careful not to get up too fast, turn too quickly etc. especially after working out. If you work out make sure you're drinking lots of water!

I think that if it happens infrequently you're probably getting up too fast...but if it happens every time you get up, or even daily that would be less normal.

Make sure that you're eating enough and that you are evenly (as possible) spreading your food throughout the day. Try to eat a little something every 2-3 hours to keep your blood sugar from dipping way low.

Are you drinking enough water? I get the spins at night (just like you might from drinking too much) if I haven't had enough water during the day.

Alternate option: No sitting on the couch. :P

Hope you're feeling back to normal soon.

i get visual darkness for about 2 seconds
blood gravitates to your legs when lying down and when you get up, your body adjusts
get up too fast and blood rushes to your head - causing lightheadedness
its probably just affecting your more because of the extra training you've been doing
and the need for more oxygen to your muscles
