OK, so self-admittedly I haven't exercised besides speed walking and some light yoga in any serious way in more than 8 years. I'm 10 months post-partum and down 50 pounds with another 50 to go on a lacto-paleo diet. I tried to work out today and it was raining so I turned on my Xbox Kinect EA sports and just doing the heart rate test made me light headed with dark spots, I couldn't even finish it!!
Don't worry, I've already set an appointment with my family doctor who is a WAPF follower himself but is that normal for an out of shape person to have this problem? I'm extremely frustrated because I know I need to do something more than walking. The only other time I get dizzy is if I get out of bed really fast or stand up quickly with my infant from a chair. Is there a natural way to deal with this? I'm feeling very discouraged right now.
Sounds to be orthostatic hypotension. There could be several causes, but postpartum mothers are one group that its prevalent in. If walking does not cause this I would recommend just sticking to brisk walking until you get a full check up to rule out other causes, and proceed from there.
More exercise variety is of course going to be preferable, but walking is AWESOME in and of itself.
Maybe you are not drinking enough water and your glycogen stores are too low before exercise.I feel crap when i'm low on glucose and my performance is suffering too.Eat some tubers,or make an occasional fruit smoothie to fuel yourself!
My first thought is adrenal fatigue, which would be fairly normal with a baby...your WAPF friendly doc would likely know some easy ways to test your adrenals. Low blood pressure could be a factor, like someone else mentioned. Every once in a while, this kind of thing happens to me, and it's invariably when I have not eaten yet that day. So I wonder if you eat prior in the day to your exercise? You don't mention if you are nursing or not, but if you are, just be sure to keep your food intake plentiful as well. Oh, and I agree with Dragonfly's advice to take more D...I recommend taking 1000 iu per 25 lbs. of body weight, and up to twice that much when you are fighting off any sort of illness or infection.
