EXCLUSIVE: Bethenny Frankel Gets Emotional About Health Scare: 'Something Felt Off'

Bethenny Frankel is opening up about her recent, potentially life-threatening, health scare.

The Real Housewives of New York star sat down with ET's Lauren Zima on Tuesday, where the 45-year-old mother of one got emotional while talking about her challenging battle with endometriosis, uterine cysts and aggressive fibroids, and the invasive surgery it required.

"I had endometriosis my whole life," Frankel revealed. "When I would get periods, I would just experience very heavy bleeding and pain and cramps and that was a real big problem. I had a laparoscopic procedure in my early thirties and it seemed to calm [the bleeding] down, and then later, I was able to get pregnant and my machine seemed to be working OK."

Frankel gave birth to her daughter, Bryn, whom she shares with her ex, Jason Hoppy, in May 2010. While she thought that her uterine problems had subsided after having a child, she began suffering painful cramps and excessive bleeding a few years later.

"I went to the doctor and they said that I had cysts and fibroids, which is common, and [they] didn't really feel like there was any alarm [at the time]," Frankel recounted. However, she later had a miscarriage, "which I now think [was] because of the fibroids, which were growing."

Two to three years ago, Frankel began using an intrauterine device (IUD), a internal conceptive which contains progesterone, which seemed to "calm down the bleeding" caused by the fibroids. However, within the last six months, the pain and bleeding worsened and Frankel sough medical advice at the suggestion of one of her friends.

"My doctor said, 'Okay you are bleeding, I can't tell exactly what it is, it might be the fibroids. Let's at least take [the IUD] out,'" Frankel said. After removing the contraceptive, her bleeding became exponentially worse.

"I used to be a crier, and now I'm a bleeder. A stage five bleeder. It was very, very bad and graphic and just really brutal," she explained. "I thought it was normal but then after a couple of days people around me were like, 'This isn't normal.'"

"I went back to the doctor and he sent me for a sonogram, and basically said that my uterus had doubled in size and that I had lost almost 10 percent of my blood," Frankel recalled. "[He] gave me the measurements of the fibroids, which I didn't understand."

Frankel's doctor informed her that she had a number of large fibroids that he could see, and cautioned here that there were "probably a lot more" that would be found when she went in for surgery.

She was presented with a number of different options for how to treat her serious fibroid problem. "He said, 'You could get a myomectomy,' which is you go through my C-section scar and take all the fibroids out, [or he could] do a hysterectomy, which was very jarring just to hear that word."

"I'm no spring chicken, but still it was like, that's not a word I want to hear," Frankel added.

After getting her doctor's diagnosis, Frankel said she began to get a lot of advice from her friends on how to handle the situation, and was repeatedly told to get a second opinion instead of opting for surgery right away.

Another factor that swayed Frankel's decision to delay the procedure was a long-planned trip to Aspen, Colorado with her young daughter. "It was her break and I really didn't want to disappoint her and waste the break, or the precious time I have with her," Frankel explained.

While the reality star was leaning toward the myomectomy option, she was told she'd need to write a living will and would require six-weeks of recovery time, making the Aspen vacation impossible. So, Frankel decided to try some alternative treatments.

She went to a doctor who specialized in female hormone treatments, who put her on a "natural version" of progesterone. The treatment, which would stop the bleeding, but couldn't be taken for long periods of time, was one of several options she attempted.

"[I] was taking all kinds of pills, and iron, and vitamin C, and natural progesterone, and the stronger progesterone," Frankel said. Things "calmed down a little bit" and the reality star decided to go on the trip with her daughter.

Unfortunately, things didn't go well for Frankel on the trip. She ended up needing to be hospitalized when he pain and bleeding kicked back up tremendously.

"That was really bad, because I had really tried to hold it all together, and I really didn't want to disappoint her on this trip," shared Frankel, who got choked up thinking about her little girl. "It was just scary, I had my daughter in the hotel, I had to find a baby sitter to go watch her while I went to the hospital."

When she got to the Aspen hospital, Frankel was treated by "a great OBGYN who happened to be there in the middle of the night." The doctor did another sonogram on Frankel's uterus and discovered that the fibroids had grown significantly since she last had them measured.

The OBGYN in Aspen advised Frankel to listen to the advice of her personal physician, which was enough to get her to commit to getting the myomectomy. So Frankel and her daughter returned home to New York and she booked the surgery.

Contemplating the procedure, it was clear Frankel was getting emotional thinking about her daughter and the effect Frankel's health scare had on her.

"The surgery gave me a lot of anxiety, and it never would have if I weren't a mother," she explained. "It just really was different. You don't like to hear like, 'Do you have a living will?' You start to think about all these crazy things."

While Frankel was worried about the turmoil her surgery might cause on her young child, the former talk show host said that Bryn actually had a surprising level of understanding when it came to why her mom was going under the knife.

"When I actually did go to the hospital and said, 'I'm getting surgery, we're going to the hospital for a couple of days,' she said, 'Is that going to stop your bleeding?' So she understood," Frankel said. "It was like a very 6-year-old explanation [but] she did make the correlation between the bleeding and 'Now you're going to stop.'"

"You just think of things very differently [when you're a parent]," she added. "You're more emotional. You don't want to go under."
