Dizzy spells
 
DH is in training so has been obsessively taking his pulse several times a day. Out of curiosity he took mine and it turns out I have a VERY low heart rate - 41 bpm. When i work out it ranges between 99-120 depending on what Im doing, again low for someone exercising.

Anyhoo, since Ive been LCing - about 5 weeks - I've been having a few dizzy spells and they're coming more frequently. Tonight I did a work out, lay on the floor to recover, and when I got up I fainted. I've always had low blood pressure, but havent fainted in years.

Is this a typical side effect?

Howis your salt intake looking? I think the wise owls here will tell you th drink broth and get more salt. Hopefully they will chime in.

If that heart rate is accurate, I'd suggest you see a doctor ASAP.

When I was undiagnosed hypothyroid, my heart rate was recorded at 57 during some testing, and I was told that any number below 60 was 'problematic.' Some people will have a 'natural' rate in the high 50s, but anything below 50 should be checked medically. It is abnormal and can be life threatening, according to what I was told.

My wife had a fainting spell. She had all the cardiac tests done, EKG, echocardiogram, 24 hour halter monitor, and tilt table. They couldn't find anything wrong and chalked it up to dehydration because the was breast feeding and not taking in enough fluid.

She also has a naturally low heart rate and blood pressure.

I 'think' my salt intake is quite good. yesterday in particular it was higher than usual. I dont ahve the symptoms of hyperthyroidism - google is my friend :) It could be dehydration since it happened after exercise, although I do drink a lot.

Hubby wants me to see a doctor as well. I didnt really want to since at this stage he doesnt know I am LCing, and I dont know what his response will be :(

If your salt intake is high enough, I'd also take a look at your other electrolytes... how's your potassium intake? Do you supplement with anything at all? I'd keep an eye on your iron/ferritin levels as well, as being anemic or having an iron storage problem (ferritin) can make people experience some increased weakness and dizziness.

I would definitely be curious why no one's ever found a cause for the low BP/low heart rate though! Maybe time to see a new doctor, or a specialist if it doesn't clear up?

I meant to add... especially when you're working out, be sure you're getting enough calories! I know a lot of people new to LC actually under eat because they're not aware of how many calories they should ACTUALLY be eating versus. That can cause all kinds of nasty issues!

I take a multivitamin, but it possibly doesn't contain enough potassium for a low carber. I dont believe my iron is a problem. I had ironic anemia up until my 30s. I also eat a lot of red meat since I grow my own beef and lamb. We would eat one of the other 5 nights a week, easy.

The low blood pressure is from childhood. Its just a part of me. In fact I was tested for leukaemia because of that, the anemia and frequent nose bleeds. I dont know about he low heart beat tho as I've never paid any attention to that.

I suspect it may be a calories thing since I was kind of hungry the last few days and I ignored that
thinking it was just daylight savings body clock screw up. However my weigh in this morning has an almost induction size loss.

Thanx for you thoughts. I am still going to see my doc just to be sure, but I think I'll be fine :)

It definitely could be a calorie thing... it usually turns out that we need far more calories than we think, due to all the low fat "fad" diets out there pushing the "calories in, calories out" mentality and theory on us. LC has pretty much taught us what a load of crap that is! :laugh:

I'd look into supplementing your potassium for sure, just to be safe. A multi usually doesn't contain enough of any one thing to make up for a deficiency and there's no danger in taking additional potassium (unless of course you take prescriptions that warn against taking supplements, but you obviously don't if you're already on a multi). Women lose potassium far quicker than men do when they sweat, and since you're exercising that definitely comes to mind... especially since many LC-ers are already low on potassium to begin with :)

Also, I wouldn't dismiss iron so easily. Your blood serum levels for iron may be perfectly fine, but your ferritin may be insufficient. That would basically mean that due to your diet (the red meat, etc) there's enough iron in your bloodstream... but your body isn't storing it to utilize it properly. Doctors don't normally test for ferritin levels unless you specifically ask for it, or if they're looking for something specific like a thyroid condition for example. Many people have great serum levels of iron, but poor ferritin... so that may be something to look into!

Either way, good luck to you and I hope you're feeling better soon!

Saw the doctor. She was impressed by my low heart rate, and tested me lying down and sitting up. Same with blood pressure. Both stayed the same. She was a bit concerned about the dizziness and fainting so ordered some blood tests.

You know how some nurses can take your blood so gently, its like its a stick of butter in your veins? Well, I didnt have that nurse :( I also got to have my first ever EEG which said I have a good, healthy sinus rhythm. its just a whole bunch slower than most others :)

So next week I can ring and get the results. She's testing for diabetes, hypothyroidism and electrolytes. The only thing i am wondering is will LCing give a funny reading for the diabetes test?

Oh, and I have the all clear for resuming working out :D

lilbeetle, I've read that low carbers can have a slightly higher fasting blood sugar than they had before they started low carbing, but I don't think it's enough to be of concern. Low carbing is actually beneficial for preventing diabetes. By low carbing, I got my A1c down from a pre-diabetes level to normal. By the way, I also have a slow resting heart rate, but not as slow as yours (54). My doctor said it's from 30 years of consistent exercising; athletes have been known to have very slow heart rates. For the most part, this is good because it means your heart isn't working as hard. Usually, it isn't problematic unless there are symptoms...which you are having, but, hopefully, it's something that can be easily treated. Good luck and please keep us posted!

Results are in...


Normal.

There was an offer to explore this further but since it costs $$$ and since there have been no fainting episodes, and much, much fewer dizzy spells, I declined. I suspect it was just something to do with my body chaging over from carb fueling, to fat fueling.

I did up my salt intake, my fat intake and drank more water, so they might have helped too :)

Thanks for your help everyone :)
