This past weekend I was feeling fine. On Sat, I went for an hour ride in 111*F heat. On Sun, which was only in the low 100's and overcast, I spent the whole day cleaing out my garage and lifting weights. I was okay. Had some dinner (fast food - something I rarely, rarely do), watched a little TV and went to bed at 9:40 PM. As I hit the pillow, I suddenly felt so dizzy and a bit nauseated. I got up at 2:30 AM and couldnt' maintain my balance. I felt very dizzy and very nauseated. Went back to sleep. I got up at 5:00 AM for work and felt even worse. Any movement of my head would make me really nauseated. The only other time I've felt this bad was when I was drunk, and I mean really drunk - did wayyyy too many vodka shots at a party. So I used the bathroom and within a few hours, I felt okay like 90+% better. I can shake my head, spin around, lie down, get up, etc. and not feel nauseated anymore. Any ideas? All I can think of that caused this is the fast food I had last night, but my parents also ate the same thing and they are okay. And I don't particularly care to go to the doctor if I'm feeling okay now.

Well my old man just got back from his heart attack exercise program and spoke with the nurse. It was most likely heat exhaustion. On Sat the heat index was 118* and about 105* or so on Sun. The nurse said to drink lots of fluids: water and Gatorade. I guess there is a difference between working out in the 90*'s and working out in the 110*'s.

You might have the doc check you out
for hyponatremia. A wierd situation under
which even if you have high blood pressure
you cannot retain salt. This is especially
dangerous for folks like us that do intense
exercise in 110+ heat.

I had a bought of that in 2003, but got
off my diruretics and am good to go in
the heat once again.

I don't know why, but I do find
it a kick to ride 30 or more miles
when the heat is above 110 degrees.

At 55 though, I am nearing a time when
that will be contraindicated I am sure.

I had the same thing happen to me. But no hot days and no real big rides. It went away in a couple of days, wierd!

Heah.These treads are mysterously showing up from no where . Including me last week. Wonder why. Our symptons are similiar. It is awful. A valium shot makes all things better.
Funny. I did not realize it at first. It all cought up to me, while working on my bike out in a hot garage.

The symptom can occur in hot weather if you don't cool down gradually. I ride hard for about two hours on single track all year round and I ran into this for the first time a few weeks ago. I'm riding about 25% faster this year and I suspect that's why I'm just now running into the problem.

I drink a lot and I use all four electrolytes. I read an article that said that you don't want to just stop stressful exercise in hot weather. You need to gradually decrease the level of exertion to cool down. So now I do this for about 10 to 15 minutes. It seems to have solved the problem so far.

regardless - go see your doctor. Have him check your BR and take some blood. They will probably tell you not to work out when it's so hot and to keep your self hydrated. I'm one of those 'just in case' people that thinks a visit to the doctor will show everything is alright, but you should go...'just in case'...

I certainly don't want you to think what's happening to you is what happened to me, but I had these exact symptoms that came and went for a couple of years. Turns out I had a benign tumor in my ear. It started out pressing against my balance nerve. Eventually it affected my hearing and facial nerves, but not until a month before the diagnosis. I was fortunate and it did no permanent damage to my hearing and face, but my balance isn't what it once was and I don't think it will ever return to "normal". It couldn't hurt to go see an ENT specialist and get it ruled out. I got the impression that they can tell something is fishy pretty easily with their special ear microscopes.

When my weakness turned to trembling, we called in the local doctor. To stop the shakes, he gave me a valium shot. He said it was a heat attack.

Dudes WTF, are you trying to freak me out? Hehe, no, I didn't have anything like that - brain tumor or heart attack. It was just simply too much fun in the sun in 110+* heat Sat and Sun. I only had that Sun night to Mon morning and then it's gone. No doctor for me unless I'm dying.
