I am 10 weeks out of surgery with a 46lb loss yay me, and have recently begun a gym routine and and boxing class.

On the days I do weights I am usually fine but sore for a few days

But any day I to intense cardio, I find in the evening I have the worst headaches to point I cant handle bright lights or loud sounds.

Just wondering if anyone has experienced this or having any ideas what could be causing this

It is because you are dehydrated. You need to hydrate before during and after you exercise. Also appropriate stretching before and after along with a cooling down regimen will help as well.

Definitely drink a lot more. I also found that my blood sugar dipped really low after cardio, so I literally started eating 5-7 gummy bears after each workout and that helped!

I carry a drink with me everywhere, but will defiantly try topping up before/ after sports

I do feel very weak straight after so I may take up your idea @@JamieLogical

Someone else here on the forums actually suggested it to me. The type of sugar in gummy bears is processed very quickly and quickly elevates blood sugar levels the same way the special tabs that diabetics take do. I was getting dizzy immediately after working out. Eating just a few gummy bears would make me feel better very quickly. But obviously, don't overdo it. They are pure sugar and empty calories!

I agree, it sounds like you are dehydrated. You should be drinking lots throughout the day leading up to working out, not just during a workout.

Headaches have stopped! I think it was just my body getting used to all the new activities! But thank you for everyone's input !
