Dizzy while exercising

Definitely make sure you're fueling your body properly before you begin your workout. Try and get a carb and a protein in there.. like oatmeal (complex carb!) and a protein shake, then workout 30min-60min after. Also make sure you're warming up properly to get your heart pumping... I always have to do a solid ten minutes of cardio before I begin circuit training because of my low blood pressure, or else I experience the same dizziness you do.

Have some good quality carbs 30-60 minutes before exercising, and keep yourself hydrated.

I workout first thing in the morning, so have oatmeal before I leave for the gym and then get through about 1L of water while working out.

Also, make sure you breathe correctly. I have a tendancy to hold my breath, so when I do breathe all most of the Oxygen get's diverted to my muscles and giving me a headrush. hehehehe

If my blood sugar is too low I have this problem. I had to up my calories and protein intake to get my dizziness to stop! The protein keeps the blood sugar levels more even. When I don't get my calories in that I should I have dizziness with fast or sudden motion. You may have to play with your diet to figure out what eliminates it for you!

Start by logging your food and keep a workout journal for a week or so. In the food journal, try to include water intake and times of your meal. After every workout, write down how you feel. Then you can go back and see what you ate and how it affected your workout.

I suffer from low blood pressure and had the same symptoms even passed out while exercising. You need to up your salt intake and keep very hydrated. That did wonders for me

Watch to see your head position when you get dizzy. If you are getting dizzy with certain head movements it could be a vestibular problem (inner ear). Your dizziness doesn't sound like its that kind of problem though. Like everyone else has mentioned, fuel your body and keep hydrated. You need carbs for energy to burn! Good luck and you can always message me if you find that you do get dizzy with certain head movements!

All I drink is water since I cut out soda. (thank goodness) I usually eat oatmeal or a good cereal for breakfast. I do workout DVDs which have a warmup section built in. (don't know if it's enough, it usually lasts 5 mins) I ran out of my protein mix so that could be an issue too. I might not be eating enough even though I eat a lot healthier, but I think it's a combination thing. One friend told me to eat an apple before working out, but I've never thought of that.

I've also noticed my BP is low. Sometimes its in the 80/50 ballpark, but I've been told that's normal.

And how many calories are you eating?

Somewhere in the 1300 calorie ballpark. I'm going to keep a closer track on it. I think some days I let myself slip below.

Try upping your calories to see if that helps. I would bump it to 1500-1600 as I have a feeling you aren't eating exercise calories back. If that doesn't work, there is a chance you could have hypotension.

I used to get this problem very severely until I read an article about over hydrating during exercise. It's estimated that 80-90% of people drink too much during exercise. It's important to stay properly hydrated but this should be done beforehand, if you're dehydrated when you start to exercise, then it's too late to change it. When you drink large quantities during exercise it can go straight to your brain and cause dizziness (amongst more serious things). When I felt dizzy I always felt like I needed more fluid and it always made me worse. Now I make sure I thoroughly hydrate in the mornings at least an hour before I exercise. When I do exercise, I take a small amount of an electrolyte sports drink during and a decent amount when I finish, and I don't tend to get dizzy any more.

I changed my diet up a bit and it has improved. I drink water throughout the day. (usually 8 oz with everything eaten). I don't drink much during a workout, if any at all. I usually wait till I'm done. I've still been eating better but unfortunately I injured my ankle a few days ago and can't seem to recover. I've been trying to think of good cardio exercises to do while my ankle heals.

Why not just do weight training? And i hope you recover soon.

You may have BPPV. Check it out one the web. Hope this helps

Coming up too fast from any low position and getting dizzy is called 'orthostatic hypotension' - it's a fancy way of saying that the blood in the lower part of your body isn't getting to your head fast enough. Be careful coming from sitting/laying position to an upright position.

Haven't read everyones comments..but a number one reason for dizziness and fainting is Blood pressure. If you check out ok there, make sure your taking a daily vitamin and eating properly...along with LOTS of water. If you still have an issue than i think you nee to consult your doc. Also PROTEIN is a big reason why i get dizzy and feel weak. I feel like i eat enough of it, but once i feel like your feeling i eat something with lots of protein and i have to do it for a few days before i feel better. GL and i hope you find the problem.
I had worst dizziness and fainting spells when i was preggo because my already low iron levels and BP got lower and lower. It was a struggle to keep them up

You could have low potassium levels, keep track of your potassium. Usually dizziness, nausea, muscle cramps etc. are signs of low potassium. I don't really track my calories on here, but I track my potassium levels. It has been said that people ages 19-50 need about 4700mg per day. The daily recommended value is 3500, but if you're athletic you may need more than that. If you feel like your potassium levels are too low, you need to see a doctor.
Also, same symptoms can happen if your potassium levels are too high. Usually this happens if you're taking a potassium supplement. Sometimes you could be getting enough potassium, but your body is depleting it faster than it can absorb it. That's when you should see a doc about it.

^^ this exactly!!
