How do you recover from the brain fog?

It does seem like I'm going through everything with you @shakey-kate

If I said to you before diagnosis, I would get brain fog. But it doesn't really describe it.
I am an avid reader, I have a lot of science fiction, murder mystery, etc. On my bookcase, plus around 300 ebooks of every description, lots of downloading, about metabolic conditions etc. Including meds and treatment, keto, T2.
So during this period which was around four to five years, cos I was misdiagnosed with T2..
My dietary intake and lifestyle was to the doctors recommendations.
So once past diagnosis and started keto for real, and within a few weeks which included my fasting test, which I didn't go hypo. My brain woke up, the fog cleared and I started remembering things. Because the worst thing was, I had forgotten a lot of things including family celebrations, births, death, marriage, birthdays and a lot more, there are a lot of pictures of me being there. But I have no memory of it.
And the books I had read, when I did again, just didn't remember anything from them, it was reading them for the first time. An avid football fan, a coach for my local youth club. I was there but partial memories of it all.
That was the constant hypos of uncontrolled RH!
Horrible!
As I have said previously a catch breakfast is the beginning of the daily rollercoaster ride of high and lows of BG levels. That is the symptomatic effect of food, when you have RH.
As [USER=88961]@AndBreathe said carbs are like throwing petrol on a fire if you have RH.

Best wishes.

I will go through the science, as far as I can let you understand the sequence.
However, because of the hypo, during the fasting test, which means it may not be RH, Then again, as you say, the more details, there is something that resembles RH.
And I would like to think that I am not pushing you into something that may cause harm.
And I believe may have more tests upcoming.

Here goes.
RH is a food issue, it is also an imbalance in your hormonal response. And the consequences of overproduction of insulin. It is not just one thing. It is a sequence of abnormal reactions to someone who has normal blood glucose levels, after fasting for more than four to five hours such as before eating in the morning.

You have an intolerance, such as one of the sugar or grains etc, that are carbohydrates that when you eat thm, they turn into the glucose you need for energy etc, insulin is a part of the first phase response to that glucose because, that is the chemical reaction to produce energy from...
For some metabolic reason, the insulin response is not in balance with the amount of carbs/ glucose derived.
So, the more carbs, the less energy derived, the more glucose rises quickly. My spike even higher than double figures, goes up last the trigger of around 8. And the hyper symptoms start.
If this goes on for a long time, insulin resistance may impact your energy levels.
As well as the circulating insulin that is produced but not converted into energy.
This will impact your organs function to produce the other necessary additional hormones etc.
That is why fatty liver are found in metabolic conditions.
At this point of the rapid spike (instead of a normal curve) the brain is receiving signals from your body, to say that your spike is not normal., It also subconsciously sending signals to your organs, your gut biotica, your enteric system the whole digestive system that, all is not as it should be.
And demands from the organs to get the balance back.
And they do.
However, the pancreas goes into producing more than enough insulin for that high abnormal spike, this overproduction of insulin is called the overshoot. This overshoot of insulin impacts the glucose because the pancreas, brain and the brain gut axis, keeps insisting on more.
Too much insulin.
It floods into the blood, and the BG levels drop a bit quicker than normal, and more symptoms.
It drives down into hypo levels. The liver is responding with glucogenisis (liver dump) but it only has a slowing effect. And the hypo happens. It is usually arrested and the BG levels rise, but sometimes need a nudge to do so.
In summary.
You eat carbs, you spike, you overshoot, you hypo.
Not forgetting that it can be other causes other carbs, such as too much exercise, stress and so on.
And the reverse is the treatment.
No carbs, no spike, no overshoot, no hypo.

And of course, if the meal you have caused the reaction. And you over treat the hypo, it will start all over again. The rollercoaster ride of BG levels.
Hence the horrible symptoms.
And the subsequent health issues over time.

I hope that helps you understand it.
Keep asking.
Best wishes.

And just to rub it in.
I climbed Ben Nevis about thirty years ago.
And Snowdon twice.
Climbed the mountains in the lakes.
Sorry!
Ha!

It's not the staff, it's the politicians! And the medical industry, profit before lives!
And the text books that the doctors refer to.
Otherwise this forum wouldn't be needed
