Why do you get thirsty after you eat ice cream?
I just ate ice cream and i have a thirsty feeling.
In the case of ice cream, it's most likely because of the high dairy content. Like a glass of milk, it leaves your mouth feeling dry (from the milk/dairy residue left behind), and the "thirst" is your body trying to clear the coating away.
It's the sugar !!!
If I was you, I would worry.
It's usually the sugar content, works the same with eating something salty.
The sodium content of the ice cream dehydrates your body. It also leaves a coating on your tongue and throat that makes you want to drink something.
It's probably from the sugar it's normal it happens to me too
