Dizzy spells after walking?

[MrBig]

Bit of background... I lost 8 stone about 4 years back and was happily maintaining it until I lost my job and covid hit within the space of a few weeks. Mental health took a serious downturn and I put about 3 stone back on over the last 18 months or so. Finally got my st together about 6 weeks before christmas, then had some food and drink over christmas, and started back with the exercise/healthy eating regime afterwards.

In order to speed up the progress ive got into the habit of doing an hour or so brisk walk at lunchtime at least 4 times a week. Typically 3-4 miles, also tieing this in with a couple of gym visits a week. What I'm finding though is that after a walk, I am getting dizzy and a bit lightheaded for an hour or so afterwards. Is this likely to be dehydration? I have upped my water intake but wondering if its enough?

Edit: also suffering from very cold extremities (hands especially) since starting this routine. Could it be related?

Don’t mean to scare you, but have you had any of the mRNA vaccines? A chap my wife treated suffered a blood clot (lungs I believe) after his Pfizer booster and had cold extremities and dizzy spells (plus breathlessness and chest pain).

If I were you I'd reduce the routine for a while and see you feel more normal. I get dizziness but for me it's an inner ear issue. I avoid what causes it.

Seriously!! Another opportunity to bang on about anti-vaxxing!! OP, you should consult your GP rather than a chat thread on Pistonheads. Could be any number of things from not serious to more serious so best not to speculate.

It could be something serious.

It could be something simple, such as low blood sugar. It used to get to me sometimes, but I manage it now with slightly sugary snacks.

What it most certainly is, is something you should see your GP about.
