Dizzy hours after walking

eat more and stay hydrated

without knowing your current fitness level.. I am going under the assumption that exercise is somewhat new to you... and I'll share my experience with you.. I began my fitness journey a couple of years ago... at the gym... after having lead a very active life (prior to marriage) I found myself looking in the mirror and wondering WTF have I been doing to myself?... it was that "aha moment" anyway...

first day at the gym... no prep... just got changed and headed for a cardio machine.. (elliptical... still my poison of choice) ... SO... best intention... set the machine for level 1... and "cardio" keep the heart within 3-4 BPM of 135.. how tough could that be?

away we go... 3 minutes in... what??? am I sweating... wh.. why am I light headed... 6 minutes in... ohh I don't feel good... wh..why am I getting all shakey... 9 minutes in... Hmmm am I gonna be the guy the paramedics cart out of here? Thank GOD the fire hall is just across the road... 12 minutes in.. I better get off of this thing before I pass out or throw up all over the place... whew!!! thank goodness that's over with...

12 minutes... that was it... I had to walk around to get myself together... I found a massage chair...sat down... closed my eyes.. until I found "normal"...a combination of anxiety, lack of fitness, lack of preparation... lack of understanding my body... I stuck with it... eventually I worked up to 45 minute stints on that same machine at a level 7... pushing the heart rate to 165 on short intervals... except.. to get there... I have a snack of some kind.. usually a clif bar...or Builder bar 1/2-3/4 hour before I work out just to make sure I have the energy to complete the task at hand...I make sure my water bottle is full... and check my determination to make sure... that is where it needs to be too.

BUT take note... if you have not exercised in a while body chemistry comes into play... as you exercise endorphins flood your body... creating a "high" that will allow you to complete your task... in the beginning it feels like "light headed...almost "out of body"... eventually you get used to that sensation... and it all but goes away (except it doesn't you just get used to it being there).. BUT it is important to fuel the exercise too...so consider taking a snack with you on your walk...eventually you will get used to being a little light headed after a work out.. it is perfectly normal...

if the light headed dizzy thing continues after a week or two... see your doctor... Good luck!!!

Do you monitor your blood pressure? One common effect of decreased calorie intake and increased exercise is lower blood pressure. And one common effect of low blood pressure is -- you guessed it -- lightheadedness.

I'm not saying that's what you're experiencing, just raising it as a possibility. See your doctor for an actual diagnosis.

In my case high blood pressure is a worry when I'm overweight, so I've come to enjoy the mild lightheadedness that signals lower BP. But I have to be careful it doesn't get too low and lead to fainting.

I get dizzy occasionally from exercise, I found it can be any one (or a combination of) the following:
1. Not drinking enough water
2. Low Iron (I got blood work done and my doctor recommended iron supplements)
3. Low blood sugar

eat more and stay hydrated

Simple yet the best advice. I used to have mega head aches when I was younger when I started working as a waiter which is a super active job and has you working in a hot kitchen. Started drinking more water and the head aches went away and never came back.
