Olsen Twins: 'Fuller House' Emptier As Mary-Kate And Ashley Olsen Skip Show Amid Lyme Disease Reports

The Olsen twins will not appear in Fuller House. Amid rumors that Ashley Olsen is struggling with Lyme disease, neither she nor Mary-Kate will return to the iconic situation comedy scheduled to air on Netflix, according to the Hollywood Reporter.

On the original Full House, the Olsen twins shared the role of Michelle Tanner. But although fans hoped that they would take part in the revival on Netflix called Fuller House, executive producer Robert L. Boyett set the record straight.

"Although Ashley and Mary-Kate will not be a part of Fuller House, I know how much Full House has meant to them and they are still very much considered family. It has been exciting to see how they have built their professional careers, and I support their choice to focus on their fashion brands and various business endeavors. I appreciate their support and good wishes towards Fuller House."
As to who will appear in Fuller House?

Candace Cameron Bure (D.J.), Jodie Sweetin (Stephanie), Andrea Barber (Kimmy Gibbler), John Stamos (Uncle Jesse), and Dave Coulier as Uncle Joey are to return. Bob Saget and Lori Loughlin may appear in Fuller House as well.

But it was the Olsen twins who became the subject of speculation after they claimed to know nothing about Fuller House. Stamos attacked them on Twitter for their comment, which he then deleted.

In recent years, Ashley and Mary-Kate have been focused on their fashion careers. They have two lines of attire, Elizabeth and James and The Row.

And despite acting on Full House at 9-months-old, the twins have spent years away from the small screen. As the Inquisitr reported, Ashley Olsen has Lyme disease, and those who know the actress and designer say that it's getting progressively worse.

And now Ashley, with her twin Mary-Kate Olsen by her side, is fighting to regain her health. The first hint that something was wrong came in 2012.

"I don't like to be the center of attention anymore," said Ashley, abruptly retreating from the spotlight.

But it now appears that she may have exited the entertainment world prematurely because she was trying to hide her diagnosis of Lyme disease and the enervating symptoms of that condition.

"She's really sick," revealed a source.

But what is Lyme disease, and how does it affect the body? It's more devastating than most people realize, and it also has a higher rate of infection than commonly known, according to Healthline.

The U.S. Centers for Disease Control and Prevention (CDC) estimate that 300,000 Americans receive Lyme disease verdicts annually. Most of those diagnoses occur in the Northeast and the states between Wisconsin and Minnesota.

People develop Lyme disease after being bitten by a tick infected with Borrelia burgdorferi. Symptoms range dramatically, making it difficult to diagnose the disease. They may range from muscle aches and exhaustion to brain fog and depression.

As the Inquisitr reported, both Yolanda Foster and Avril Lavigne also have battled Lyme disease.

The singer has revealed that the diagnosis came only after she spent five months suffering to even breathe as she lay in bed, feeling helpless.

"I felt like I couldn't breathe, I couldn't talk and I couldn't move. I thought I was dying."
