Headaches after workout

[Pink nova 99]

Any insight would be greatly appreciated 🙂

I have been working out 6 days a week doing 45 minute kickboxing which burns about 500 calories. The classes are intense but I just can not get my heart rate up high to burn a lot of calories like some other women there. My heart rate is also super quick to slow down during the short rest periods in between rounds.

I have been taking double classes just to increase fat burn and calorie loss but every time I have done that, I end up with a raging headache all night and morning. Tylenol doesn’t fix it...it literally keeps me from sleeping. I feel nauseous and weak. I burn about 950 calories in those double classes and I eat about 1200 calories per day. I have tried to eat bigger meals before my workout but that doesn’t help. I always have a Premier Protein drink after my work out. I also stay hydrated throughout the workout.

I really love my double classes as it’s such an intense workout but I dread feeling like crap afterwards. What changes should I make?

Thanks for your help!

You should get your blood tested and see if you are lacking Vitamins. It sounds like you might be low on potassium. Keep an eye on your blood pressure too. Drink this stuff instead of Water when you're working out.

It sounds like deyhradtion, but I'm no Dr. I think I would consult with your PCP or Surgeon. It also could be low electrolytes.

Headache is a classic dehydration symptom. Are you consuming electrolytes with your Water during your workouts? If not, it's a very good idea to do so.

Thanks for all of your input!!!!! I tried Powerade zero today to rule out dehydration and I was still getting crazy headaches although not as bad as before.

I was moping and feeling sorry for myself lol and then a lightbulb went off...low blood sugar!!!!!!! I feel like an idiot. I have type 2 diabetes but I’ve been off meds since my surgery and it’s been a non issue. I checked my blood sugar levels and it was 3.9 which is low especially since it was hrs after my workout and I already ate. After having some sugar, I felt better. I could kick myself for not thinking of this sooner but ahhh well. At least I know now!!!!
