I am 45, and this time last year I was a 260 lb blob of fat that was afraid i wouldn't be able to get back up once i bent down..(the knees :( )
After doing circuit training classes 1-2x a week, plus working out 3-4 additional days a week, Ive dropped to 226-228 and feel and look much better. Problem is, during the circuit training classes I get dizzy after 15-20 minutes and need to take a 30 sec break every now and than. Things start going gray, and I need to stop and support myself. Kind of curious what is causing this. On CT days, I make sure I eat plenty of carbs....for breakast its usually oatmeal, but sometimes eggs and potatos with whole wheat bread. 45 minutes before class Ill have a piece of toast. would like to get through one class without feeling like Im going to hit the floor. thanks |

Well, it may or may not be normal. You're not used to exerting yourself...I think we ALL get dizzy sometimes, I know I do...it's just a matter of where that threshold is.
A little advice- you don't need a lot of carbs. Some is great, "plenty" is usually more than needed and makes it hard to lose fat. Try to get protein and fat in at every meal. Just oatmeal isn't great...a whole lot of carbs and not much else. ETA- I'm not a doctor though, so for all I know your heart may be on the verge of exploding. |

Quoted: The symptoms make me think it's low blood sugar levels. Maybe have some blood work done to see if everything is alright and it's not something more serious. It definitely doesn't sound normal. I'd be inclined to say its more circulatory in nature. The "graying out" is what makes me say this is likely non-neurological... Syncope (or pre-syncope) can usually be attributed to the pump (heart), the pipes (arteries/veins), Something in the pipes( blood- pressure, volume, sugars, etc)... Then look at the brain (intrinsic or otherwise)... Most commonly )90%+ its cardiac... Without seeing and examining the OP, i cant give much more info/help. Get your heart/bp checked out by your primary doc. |

What's your blood pressure? Were you taking BP medication when you were big and are you still taking it??????? +1 Any chance you can have someone check blood sugar when you feel light headed? Maybe check your heart rate and oxygen saturation with a pulse oximeter. Make an appointment with your MD. |

BP: at my last physical (4 months ago) when my weight was in the 260-265 range was 120/76. I take no meds on a routine basis.
Water: I drink a minimum of 32 ounces a day.. Clarification on carbs: The only time I have a carb heavy meal is on days that I have crossfit (as per advice from the trainer). I thought also it was from lack of sugar, so a couple of times Ive had some fruit or something before class and still got dizzy. Doing any kind of medical diagnostic while exercising isn't possible (or would be very difficult) during the class due to a lack of equipment. Defintiely will be following up with my MD. |

Get blood sugar checked out. Protein prior to workout and see if that helps.

| You guys need to get off the hypoglycemia boat already. OP, see your doc asap because you'll probably get bounced around getting set up for a stress test and/or echo. The longer you wait, the longer the referral might take. I'd bet $20 you have ECG changes with exertion or some valve/shunting issue. |

It would be interesting if he had an arrhythmia leading to dizziness and not shortness of breath. Have you had your cholesterol checked lately and also have you tracked your HR during these classes? |

Ive never monitored my HR during these classes...from time to Ive thought about getting a HR monitor, but frankly just don't want to spend the money on yet another gadget that in a years time will be in a drawer with other gadgets that are no long used... |

Have you every checked your HR during one of these episodes? If it happens before you see your doc just check your radial pulse and make sure your HR is below your age predicted max HR (220 - Your Age). if you are getting close to or exceeding your max that might be a good indication of why you need to stop and catch your breath and or one differential for the dizziness. |

Quoted: It would be interesting if he had an arrhythmia leading to dizziness and not shortness of breath. Ive seen dozens of patients with exercise induced syncope/presyncope caused by an arrhythmia, whether brady, tachy, or irregular... Some people just vagal down during exercise.

Could very well be something as simply as blood pressure.
Yesterday when I was doing my manimal back workout (dead-lifts supersets with dead hang pull ups) I would get light headed and I could feel a slight headache throbbing. I would simply allow a few minutes more of rest between sets to lower my heart rate and hit it again. When you get dizzy or light-headed just rest a moment to two. |

OP, does it happen around the same point iin your CT? Changing of positions/planes? What about other forms of exercise? It usually happens about 15 minutes into the CT training class and I think it is independent of a specific exercise. I also don't notice it during other forms of exercise...for example I can get on the stairmaster, elliptical, etc. and maintain 80% heart rate for 10-15 minutes and not get dizzy. To answer the post before yours, no..I do not take any weight loss supps. Also, this week was a little bit better....I was scheduled for bloodwork first thing in the AM on the day the class is held, so hadn't ate anything from about 8 pm the night before, until nine am after the blood was drawn...at that point I had a peanut butter and jelly sandwich, and than at ten am a banana....class was at 11 am.... Basically, this was the best I ever did in class in terms of stamina and being able to push myself...I think I even the impressed the instructor, as she said it was the best she had ever seen me do.... So, it might be food related (but I still plan on following up with the doc). |
| You should be drinking half your body weight in ounces of water per day. Could be blood sugar related. I have blood sugar issues and the best way for me to regulate is to make sure I eat a good amount protein before and after workout. Also bananas are perfect for 30 min before a workout. I used to play tennis professionally and they are a staple. That's why you see tennis players eating them during the matches if they go long enough. |
