Hypoglycemia after eating avocado

[LeoS9]

Hi, i'm 21 and today is the second time i notice a really unusual and apparently unexplainable symptom.
This afternoon i ate some fruit (some bananas and oranges) and after 2 hours i ate an avocado with some egg yolks; once eaten the avocado, i started experiencing hypoglycemia-like symptoms in 15-20 minutes.
The symptoms were: sudden weakness with inability to walk (i had to sit down) and tremors; probably also some degree of lightheadedness. The symptoms resolved in few time (10 minutes) spontaneously.

I've eaten avocado many times this year, but this is the second time i experience hypoglycemia symptoms after eating avocado. The other time this happened i ate 2 avocado following (2 hours later) a meat serving. That time i promptly consumed sugar as the symptoms were particularly strong.

What could cause a similar reaction? Please notice i suspect a SIBO condition, and maybe hypochlorydria.
Another thing i thought of is a vagal response, due to unknown reasons.
I have no hypoglycemia nor reactive hypoglycemia, but on a high carb diet i experience tiredness after eating. Thyroid panel is normal.

What could be the cause?
Thank you in advance
