Bethenny Frankel is sharing a medical announcement with her fans and followers. "Months ago, I decided I was going to be very proactive about blood tests, bone density, all the things I heard people talking about," Frankel, 55, shared via Instagram on Thursday, January 22. "I started to take a series of blood tests. Each time, my kidney function was coming up low." After making an appointment with a kidney specialist, the former Real Housewives of New York City star received a diagnosis. "He said to me, 'You have stage 2 chronic kidney disease.'" Frankel revealed.
