Had a few dizzy spells doing an easy zone 1 run today to the point I had to sit for a while and walk back
heart rate was completely normal and in range (sinus rhythm according to apple watch), Blood pressure was also completely normal.
Not sure going to the dr would do anything since they were all normal, just looking to see if anyone else has ever gotten this?
My training and fitness has been the best it has ever been so not sure what to think.
You might be dehydrated or drinking so much water during the day (this is my problem) that your minerals and electrolytes are out of wack. I have been using LMNT (warning: very salty) and it’s been very good. I’m also a heavy heavy sweater when I exercise.

Good response. Was about to post the same, with the exception of I’d previously used Precision products. For both yourself and the OP, you might consider matching sodium content of your beverage by making your own with sodium chloride instead - I started doing this after going over $1,000 on Precision products and I don’t notice a difference - throw it in the soda stream and I’ve got quality club soda.
EDIT: Citrate, I use sodium citrate
I’ve gotten panic attacks while running - some mild that I can push through - others severe and I had to walk it off.
Also, in very hot temperatures I’ve felt lightheaded, namely the run in Haines City FL 70.3 2019 was hot for me.
My battle is to try to not psych myself out.
Yes, I’ve had this when it’s hot, including after a workout. Same symptoms, no heart rate or blood pressure issue. My experience is that it only happens when it’s very hot and humid. So I think in my case it is mild heat stroke and/or dehydration (if those aren’t the same thing). Yesterday and today I worked much harder are trying to be hydrated, with crystal clear urine just before I started the run. But I still had the issue. As I become more heat adapted, it drops off tremendously. I just try to be very careful when I feel it coming on and walk.
Lightheadedness? Weakness? Actual sensation of seeing things spinning? Depending on age, family history, other factors this could be nothing or could be serious. I would err on the side of getting checked out, especially if you are older or haven’t had a physical in awhile.
Here are the 3 most probable things:
If no reason to believe 1 or 2… I’d get to the doctor.
Common symptoms of mild/moderate hypoglycemia:
Fatigue/exhaustion
Inability to complete routine exercises/tasks
Intense Hunger
Nausea or stomach discomfort/pain
Shakiness
Lightheadedness
Weakness
Sweating
Irritability
Common causes of hypoglycemia:
Rebound hypoglycemia, ie. blood sugar crash. Most commonly recognized in children after they eat candy, run around like crazy and then start wailing. Ironically, the same thing happens in adults, we just (usually) don’t cry about it. The surest way to induce rebound hypoglycemia would be to consume a high glycemic index meal 40-70 minutes prior to exercise, and NOT consume any high glycemic index foods during exercise. Even in cases of more moderate or low glycemic index food consumption in that time window before exercise, rebound hypoglycemia is remarkably common. Another common way to create rebound hypoglycemia is to either consume too little intra-workout carbs during a portion of training, or to delay post-workout carbohydrate consumption by more than 10-15 minutes especially if intra-workout carbohydrate consumption was on the lower end of the spectrum for the work output or duration of exercise.
Intense exercise in the absence of carbohydrate or minimal carbohydrate. Work out for long enough or hard enough, without sufficient carbs, and you’ll surely begin to experience mild hypoglycemia.
Prolonged period of no food consumption. Don’t eat for 12 hours, and you’re likely to experience some level of hypoglycemia as your body works hard to run in a low carb environment.
How to prevent it:
Don’t eat 31-75 minutes prior to exercise.
If you must eat in that dreaded window, be sure it’s a balanced meal, low in fat, AND ensure that you have intra-workout carbs during your workout and are actively drinking them IMMEDIATELY from the onset of exercise or even just before you start, and throughout the entire workout.
If you need to eat closer than 90 minutes to your training, try to do it 10-20 minutes before training, and make it something very easily digestible (like intra-workout carbs) so that it’s not sitting in your gut doing nothing while you train.
Ideally, eat ~2 hours prior to training. The more complex the meal is, with more fat and more fiber, the longer before training is advisable.
In cases of workouts lasting 75 minutes or more, you MUST have intra-workout carbohydrates, or you’ll surely risk the onset of at least mild hypoglycemia by the end of your training session.
How to FIX it, if it happens:
If you’re in middle of workout, drink 10-50g of carbs depending on how much you have left, and how far behind you are on your “scheduled consumption†assuming the target was to drink steadily until the end of the workout, at which point, you’d be out of intra-workout carbs.
If you’re not training, reduce activity level (sit) if possible. Drink 4-12oz water, depending on thirst, and consider moving all or part of the next meal’s healthy carbs to right now. Wait 20 minutes. If it persists intensely, consider adding 20g more healthy carbs, or moderate-moderately high GI carbs like banana, melon, mango, white rice, skim milk, most breads.
Cause is drop in blood flow through the neck to the head. Doesn’t have to be much, and is localised (there are multiple feeds into the cerebral area).
I get this a lot early morning just of the gate, or definitely if I am straining my neck and shoulders (ie waterskiing) too much.
It’s really under-diagnosed but the simple mechanical of restricted flow due to neck & shoulder overuse - which can cause concussion-type effects. A good example is Sidney Crosby, all the BS of high power docs this and that. I called it as a neck issue, having had the same type of head twisting hit.
And it was!
In certain situations I have trouble standing, have to hold on to something at times.

Yes, I have had this several times. Including twice actually fainting while running with resulting ambulance trips to hospital! The last one was earlier this year where I fainted and fell over a 50ft bank! Luckily only had a few scratches. Was unconscious a few minutes but took 20 mins to be fully lucid.
I have had the full battery of cardiac and neurologic tests and everything is structurally fine.
It has only happened for me when doing an easy recovery run, the day **after **a very heavy IM training weekend. I start feeling a bit light headed, seeing stars a little, if I stop for a bit then i’m usually ok. It’s when I think i’ll just carry on to that bench / water fountain a couple of mins away that I faint.
Doctor’s can’t pinpoint *exactly *what it is but as per DrAlex above, I suspect reactive hypoglycemia. These episodes have been when probably glycogen depleted and have eaten carbs not too long before running. If I run fasted i’m fine. HR is fine during, haven’t checked the sinus wave.
I’m wondering if the Supersapiens tracker would be useful to track blood glucose and correlate.
One thing to check is your resting blood pressure (post it if you can). Mine is low, a bit lower than my 20 year old son, who was a comp swimmer & fit.
My resting heart rate is in the mid 40’s.
Your blood flow is at its best when there is no digestion happening, and the body is properly hydrated.
For hockey I never ate anything within that 3 hour window before the game. Probably should have tried gels tho!!
6-7pm training at the gym doing squats, I got blurry vision and dizzy. Had to collect myself, before continuing the workout.
Blood flow directed to the legs +low blood pressure and corrupted by what I ate through the day.
I’m a lot better these days combination of low dose ASA, and legs & body is in better shape overall. But it’s remarkable, I was able to isolate that working my hamstrings in deep bend, single leg squat etc is connected to the dizziness/head rush thing.
