What just happened?

[WhodoVoodoo]

I had a small breakfast this morning (cup of tea and a bowl of yoghurt) and have been out walking the dog. Various things meant that lunch was delayed. I started preparing lunch when I felt very hungry so grabbed a banana. After eating the banana I felt dreadfully sick and went for a lie down. I happened to notice that my heart rate was 46! Normal resting heart rate for me is high 50s low 60s. What just happened? Surely being hungry/thirsty increases heart rate?

I'm fine now, just curious about mechanisms at work here.

My unscientific guess would be your blood rushed from your periphery to your stomach/internal organs to start digesting the banana asap?

Did you take your pulse manually or with a tracker?

I can’t eat bananas I feel sick about 15 mins after eating one
I don’t know why I feel sick but I don’t have them even though I actually like them
Have you ever had a reaction before ?

Too much potassium when blood sugar was already low.

MassiveOvaryaction I have a Fitbit on. I could hear my heart sounded slow so just opened my eyes to take a peek and pulse was through the floor. I think your theory sounds likely.
KrazyboutKillian I'd literally just finished the banana so there wasn't really any time before I felt so sick I went to lie down. No, never had any reaction to bananas - I love them!
PetrichorSoul Not sure my body would have absorbed anything from the banana that quick? I'd just finished it.

I'm not anxious just curious. Thank you for replying.

Then I’d guess reactive hypoglycaemia if you’d just finished it.

There’s a lot of sugar in bananas.
