Teen Mom 2’s Leah Calvert’s daughter Ali Simms may become wheelchair bound

UPDATE: Ali Has been diagnosed with a rare form of muscular dystrophy.

Leah Calvert has struggled to learn what’s ailing adorable Ali Simms for the past few years, which fans of Teen Mom 2 have watched play out on screen. Last spring, Leah and ex-husband Corey Simms seemed to get some long-awaited answers about Ali’s mysterious health problem. Unfortunately, it seems Ali’s condition has only deteriorated in the time since.

“Things went from bad to worse with Ali and it turns out that she could have to be in a wheelchair soon,” a source close the family told Radar Online, adding Leah and husband Jeremy Calvert decided to move to a wheelchair accessible home after learning the news. “They are also planning on getting a place that allows horses because that will be part of Ali’s therapy.”

The source didn’t go into specifics about Ali’s condition, only saying it was “some sort of mitochondrial disease” that will worsen. That must be particularly devastating for Leah and her family, as they have hoped Ali would be able to walk without assistance.

“Ali has been doing therapy for a few years now and seemed to be improving, however, from what the doctor told the family at Ali’s big doctor appointment in July, her disorder will just keep getting worse,” the source said.

Although Leah hasn’t addressed any specific developments with Ali’s health, she did allude to some challenges this summer via Twitter.

This is happening, is it real? I can wake up from this nightmare at anytime now!

Leah’s former father-in-law also tweeted about the family’s fresh pain after a doctor’s appointment in July.

Every few months we make a journey full of hope only to go home with our hearts ripped out.

After that, Leah confirmed she and Jeremy made the difficult decision to move the family into a new house.

After purchasing our first home together and now moving for the reasons we are is hard to adjust to, but I know it is best for our family!

It would be understandable for Leah and her family to focusing on Ali’s handicaps, considering they just want to learn how to best address them and help the sweet little girl succeed. However, the family maintains an incredible “glass half full” attitude.

When I pray for Ali, not only do I pray for her to overcome her issues, I thank The Lord for all the blessings both the twins already recvd.

The public is sure to learn more about what’s ailing Ali (and how she’s working to overcome odds) during the upcoming fifth season of Teen Mom 2.
