are you taking electrolyte supplements? the keto diet can cause you to lose sodium, potassium, magnesium. Even if you're drinking a ton of water, if your electrolytes are low it could cause low blood pressure and give you a headache. a good supplement is LMNT.
Discussion
I drink an electrolyte drink with apple cider vinegar, lemon juice and keto chow essential electrolytes throughout the day. If I leave during the day I take a big bottle of that with me but if I'm gone longer than expected I use keto chows saltt packets.
I have looked at lmnt packets but haven't tried it yet. Wanted to use up the Saltt packets first.
honestly it sounds like something is wrong, keto flu shouldn't last that long unless you are going in and out of ketosis by eating too many carbs regularly.
consider heading to an urgent care or an emergency room for a1c and urine test for ketones to evaluate for diabetes/ diabetic ketoacidosis. I once had a patient end up in the ICU for a few days by doing the keto diet when he had type 2 diabetes. certainly not, but can happen.
sounds like you're doing ok with electrolytes.
it might be good to check a metabolic panel. that will show your sodium and potassium levels, kidney function, etc. If you want to check magnesium levels, that isn't part of the normal metabolic panel, so you'll have to ask for that separately.
if you get checked out and there are no problems with Labs etc, I would reconsider the keto diet. typically when people are having success with it, they feel great, they don't feel hungry, their thinking is clear. this is certainly not the case for you. Even if you're losing weight, you're very likely to gain it all back when you stop.
I was in the ER for kidney stones last month no major red flags on any of my blood work, just some were a bit more elevated than normal. Na and K are normal, glucose is higher not sure why that's suddenly changed.
It just seems odd that the person sitting next to me is fine but everything #keto is "supposed to" help with has gotten so much worse.
I'm seriously questioning if this is the right thing for my body, if my goal was losing weight I'd probably call it a win. But I was under the impression it would help asthma, ADHD, and pain.
I'm also starting to get more confused about what it is I cut out of my diet that is causing all the issues.
I will talk to my doc about checking my magnesium. I didn't see it on any of my tests. They did a mess of teats on me besides the metabolic one.
