Mama June Passes Out ... Rushed to Hospital

Mama June was just rushed to the hospital after collapsing at her home in Georgia Wednesday... TMZ has learned.

We're told June had been complaining about not feeling well, and had thrown up several times throughout the day. She passed out right after walking down the stairs in her house. She regained consciousness, but then had multiple fainting spells ... so her daughter, Pumpkin drove her to the hospital.

We're told June has been pushing it with her diet lately, and after passing out she admitted she hadn't eaten much today.

June's still in the hospital. We're told doctors plan on giving her a CT scan and taking blood work.
