Yes even if I do go below 5 mmol ie for before I start drive my car in Australia. No longer have hypo awareness until my glucose go below 4.2 mmol heading down to 3 ish mmol for hypo awareness.
Thankfully it only happens few times not an regular everyday hypo. (I do have high positive Type 1 Diabetes genetics - is another thing doctor need to keep an eyes on - incase autoimmune/antibodies kick up positive for Type 1 Diabetes. )
However, I do agree with you, but the point is that there are certain things our bodies do not like and the intolerance is different for everyone, it is similar to an allergy, there may be a hidden food or ingredients that could be even low carb that is causing an issue you are not aware of.
When I was researching, testing, trial and error, I found many ingredients that would effect my symptoms.
A lot of these were in production foods.
Food has been a huge problem for me for most of my life. Being lactose intolerant since very young, not being able to stomach many vegetables or some spices, and of course, many other sources of nutrition, that would at the very least would have small side effects, my blood glucose levels would be all over the place, and would put me in a state of poor health.
That is why I subscribe to eat the food I trust, mainly fresh food that has never been anywhere near a factory!
