I’ve had a pretty long history with hypoglycemia and even last month i was having a lot trouble (had to eat every 90mins and even if i was 10-15mins late i would feel awful)
A few things worked for me
1) Biotin supplementation – this doubled how long i could go without food in just a couple of days, this taking 5000mg per day in 2 doses (5000mg at once gave me a terrible migraine)
2) Super clean diet – I’m far from an expert so i don’t understand the specifics but i know i improved when cutting out all fruit, sugar etc. Even a tiny tiny amount of sugar would put me on a blood sugar rollercoaster for a few days. I get my carbs from rice and potatoes, the rest of my food would be meat and veg only. Even concentrated forms of veg like beetroot capsules would cause problems.
3) Coconut oil – find about 20g-25g every 12hrs to be helpful
4) Buteyko – this is the golden bullet really, the CO2 stabalises blood sugar so quickly. I went from pretty bad to pretty much perfect in just a few days.
