Porsha Williams is recovering after being rushed the hospital in Atlanta on Monday.
Atlanta Fire and Rescue arrived on the scene and transported Williams to Piedmont Hospital.
A source later told People magazine the star was "doing OK" in the wake of the incident.
Insiders suggested to TMZ that Williams' collapse was due to her not eating.
The star's sister, Lauren Williams, had revealed her sibling has low blood sugar issues when Williams fainted on a flight from Atlanta to Miami in March.
Williams has appeared as a series regular on "The Real Housewives of Atlanta" for three seasons and co-hosted "Dish Nation" since 2014.
She will compete on "The New Celebrity Apprentice," which is slated to premiere in January 2017.
