Alexia Nepola’s life was forever altered by her son Frankie Rosello’s tragic car accident in 2011, making his latest health scare especially concerning for the cast member of The Real Housewives of Miami.

In Season 7, Episode 8 of RHOM, Alexia described how 28-year-old Frankie had been experiencing severe vomiting, which led to a trip to the emergency room.

Her older son, Peter Rosello, 32, visited the Miami home she’s renting on Venetian Islands, where Alexia disclosed that they had “finally” identified Frankie’s condition: diverticulitis, described by the Mayo Clinic as the “inflammation of irregular bulging pouches in the wall of the large intestine.”

“Managing it really requires dietary control,” Alexia told Peter. “I need everyone’s support. Certain foods can trigger it.”

How Alexia Nepola’s son Frankie’s health struggles impacted her family

Alexia shared more about the emotional impact of Frankie’s three-day hospital stint on her and Peter, who was in tears upon seeing his brother. Witnessing Peter’s distress, she recalled, reminded her of the grim period in 2011 when Frankie suffered a brain injury at 13.

“Honestly, you’ve faced many challenges,” Alexia emotionally told Peter, alluding to Frankie’s accident and the passing of his stepfather, Herman Echevarria, in 2016. “It was overwhelming, but we’re in a good place now. I don’t want you to worry.”

In a confessional, the RHOM mom elaborated, “Peter’s life was so affected by his brother’s accident because he always saw his brother, instead of being the little brother, as the older brother. Like, he looked up to Frankie.”

Now, Alexia continued, Peter is “more mature” and more “at peace,” though. That’s partly why she previously asked him to be Frankie’s guardian, in the event that she can no longer take care of him.

“I’m getting older, and he will be responsible for his brother,” the Alexia + Frankie’s Beauty Bar owner told a producer. “It’s a big responsibility, but he believes, like, ‘I got this.’”

Frankie, meanwhile, said he was feeling “good” and encouraged them both to stop crying and feeling sad.

Why Alexia Nepola avoids discussing her and Todd Nepola’s divorce with her sons

Earlier on the same episode, Alexia explained that she and Frankie were living in the rental home on a month-to-month basis amid her then-ongoing divorce from Todd Nepola.

The reason? “Honestly, I don’t know where my life is right now,” she said. “I don’t know where I’m going. I don’t know what I’m doing tomorrow.”

As she told Peter, though, “For now, I’m very happy here,” to which he replied, “That’s important. You’ve just gotta keep yourself emotionally stable.”

When a producer pointed out that Alexia and Peter “seem to avoid talking about,” she confirmed the observation was accurate.

“I don’t like to involve my kids,” Alexia elaborated. “My kids have gone through so much. My pain is their pain. So, I think it’s just easier not to talk about Todd.”
