Heart Issues Normal While Running With Calorie Deficit?

Training Advice/Discussion

5 years ago 04/16/2019 7:01pm EDT

Are low sodium, low blood pressure, and/or low blood sugar normal parts of calorie deficit dieting? Obviously low blood sugar is, and I had some mild dizziness before my run, but I really struggled with my heart working too hard on my run today.

Does anybody have any wisdom? In a recent thread it was noted that slow resting heart rate and rapid running heart rate are symptoms of low sodium, which I probably have as well.

And what are the running effects of low blood sugar? While on a diet, is it more important to get a big dose of sugar before a run?

Thanks very much.

Sounds like a person is only supposed to lose 1-2 lbs a week, and I probably lost 5 lbs in the last 10 days though calorie deficit. Guess I need to go slower and eat a little more.

Anybody deal with very low blood pressure? I almost passed out the last two times I stood up. I'm thinking my heart issues while running were from the low blood pressure.

Geez are you starving yourself? No those things shouldn’t happen and yes you should slow down and eat more. Losing 5 lbs in 10 days is way too much.

Thanks for taking the time to respond. I just read that anemia (low iron) causes postural hypotension, aka low blood pressure when you stand up. So I'll take some iron supplements in addition to my multi-vitamin.

Maybe that anemia affected my heart rate when I was jogging, slowly, and getting very tired.

It feels like I've been getting like 20-40 grams of protein a day. That's worse than Sage Canaday.

found this too:

"A lack of the vitamins B-12 and folate can keep your body from producing enough red blood cells (anemia), causing low blood pressure"

Yeah turns out my new bottle of multi-vitamins doesn't include iron. Whoops.

Since I started running 6 months ago my blood pressure went down and resting heart rate significantly down (I'm at 50 beats per minute). And sometimes when I stand up I almost pass out. Non of that happen before I started running.

It should be OK.

Consider boosting your iron intake though. Running makes our bodies burn through iron, and anemia (iron deficit) is very very common in runners.

Also don't skimp on sodium/salt, because running obviously can lead to low sodium very easily. And low sodium causes low blood pressure, which probably causes your ocassional light-headedness when standing up.

Congrats on your running and fitness though.
