Grace Nock Posted July 8 Share Strange question, has anyone experienced dizziness/ vertigo the day after a race (40 km) mnt bike or after a long ride. It's now happened for the second time, and I'm not sure if I'm doing anything wrong🙃. Saturday after race was all good, yesterday and today dizzy. TIA for any advice Link to comment Share on other sites More sharing options...
robbybzgo Posted July 8 Share Maybe you should try to identify if it's a blood pressure LOW or a sugar LOW. Some folk react to a sugar high (race day) and then have a bad sugar low the day after but that is more of a fatigue, not dizziness. It is termed reactive hypoglycemia. Do you take adequate rehydration solutions for 18 hours after a race. A mixed solution next to the bed helps if you wake thirsty in the middle of the night. Also are you eating sufficiently (protein) shortly after a long ride to help you recharge the energy levels Edited July 8 by robbybzgo More info...

dave303e Posted July 8 Share I would go see a doctor to rule out other things that may be more serious. From my own experience, Exercise Associated Postural Hypotension could be the issue. Mild dehydration causes low blood volume. When the legs stop working that are not forcing blood back up to kop and the low blood volume causes dizziness. Lie down with legs up and drink a bunch more if that is the case. I have stumbled away from a few finish lines robbybzgo 1 Link to comment Share on other sites More sharing options...
RobynE Posted July 8 Share I had vertigo after my race on Saturday but had half the red dust from the track in my sinuses and put it down to that 🤷♀️ Link to comment Share on other sites More sharing options...
Mamil Posted July 8 Share I get postural hypotension after heavy training too. A beer exacerbates it because ethanol is a vasodilator. Previous commentary about getting medical advice on forums applies. If I'm ever worried about something my friendly gp is my go to Danger Dassie 1 Link to comment Share on other sites More sharing options...

Danger Dassie Posted July 8 Share Could be any range of things from dehydration to something with diet/nutrition. Go for a checkup at your doctor, preferably one with a good knowledge/specialty in sport. Will do the necessary tests and you’ll have a better idea than anything here.

ChrisF Posted July 8 Share Where are you ? Excellent Dr in Durbanville for these things - Evert Bouwer Hopefully just a pre-, mid and post race nutritian thing. Not worth risking it though Mook 1 Link to comment Share on other sites More sharing options...

robbybzgo Posted July 9 Share I once suffered from the above. I awoke one morning and sat up and I suddenly felt as though I was on a boat plunging over a large wave. It felt as though the floor, in front of me, was falling away and I felt instantly nauseous. Someone did indicate to me what to do (as in the video above) and it came right. I did repeat the manoeuvre the next day as I still had a mild vertigo effect. I've never had a problem after that but it really can't be described as simple dizziness. The vertigo effect can feel very violent. Edited July 9 by robbybzgo Spelling Link to comment Share on other sites More sharing options...
mecheng89 Posted July 9 Share Phone your GP, make an appointment, that's my first choice. You might get referred to either an ENT, or a neurologist. Danger Dassie 1 Link to comment Share on other sites More sharing options...
