Mama June Shannon was rushed to the hospital on Wednesday after passing out at her home in Georgia.
A source confirms to ET that the 36-year-old former Here Comes Honey Boo Boo star collapsed while walking down the stairs in her house. She regained consciousness, but ended up fainting several more times.
According to the source, June told her family that she hadn't been feeling well all day and she wasn't able to keep down any food she attempted to eat.
June's 16-year-old daughter, Lauryn "Pumpkin" Shannon, accompanied her mother to the hospital via Uber, where the mother-of-four underwent blood work and a CT scan. It is believed that June is still at the hospital awaiting the results of her tests.
"June has been dieting pretty hard recently," the source told ET. "She hasn't been eating three meals a day and she hasn't been herself."
June has lost a great deal of weight in recent months, during which time she and estranged husband Mike "Sugar Bear" Thompson appeared on WE tv's Marriage Boot Camp to address his cheating ways.
June is also set to appear on the E! cosmetic surgery docu-series Botched, where she's seeking surgery to remove excess skin, following her extensive weight loss.
In fact, Mama June's entire family are currently filming a brand new "real and unscripted" reality show, according to an announcement made on 10-year-old Alana "Honey Boo Boo" Thompson's Facebook page. Check out the video below for more.
