Joe Manganiello, the 49-year-old actor known for his roles in "True Blood" and "Magic Mike," has come forward with shocking revelations about a secret health crisis that nearly cost him his life. For nearly a decade, Manganiello suffered in silence while battling a debilitating mystery illness that left him unable to walk and forced him to undergo multiple serious operations.

The actor shared his harrowing experience in an emotional Instagram video, breaking his silence just one day after announcing his upcoming memoir, "Bloodlines," exclusively through PEOPLE . In the video, Manganiello disclosed that only a tight-knit circle of family and friends knew about the health struggles that consumed the past ten years of his life.

"I suffered in silence, battling a deadly mystery illness, and other than a very small circle of family and friends, I hid it from the rest of the world," Manganiello said in the video . He explained that despite consulting with leading medical specialists worldwide, doctors were unable to determine the root cause of his condition.

The actor described undergoing what he called "very serious operations and procedures" in desperate attempts to buy himself more time . These medical interventions, he revealed, "mutilated parts of my body" and left him so physically compromised that he could not stand or walk at certain points .

Manganiello also detailed the psychological toll of his treatment regimen, saying he spent "months and months heavily medicated" while enduring "excruciating bouts of chronic pain" . The health crisis began with what he describes as a cascade of autoimmune-related illnesses that attacked multiple organ systems throughout his body.

A Seven-Year Medical Ordeal

According to the synopsis of his forthcoming memoir, Manganiello's "seven-year ordeal" involved chronic pain and what doctors described as a "life-saving organ amputation" . The autoimmune conditions affected his skin, thyroid, eyes, lungs, and digestive system . Medical professionals were left with few answers and no clear explanation for his deteriorating condition.

"It was the most brutally difficult time of my life, one I wouldn't wish on my worst enemy, but also my greatest adventure," Manganiello said in a statement to PEOPLE . The actor noted that the process of writing "Bloodlines" gave him perspective, helping him view his suffering as "a cocoon from which I would emerge forever changed" .

A Journey Beyond Traditional Medicine

When conventional medicine failed to provide answers, Manganiello embarked on an unconventional path to healing. His search expanded globally and led him to investigate his family history and ancestry in unexpected ways . The memoir documents his exploration of what he describes as "shamans, pagan rituals, ancient myths, long-lost family records and the rebirth of his own spirituality" .

His genealogical investigation revealed ancestors who survived the Armenian genocide and others who lived with chronic illness, suggesting patterns that may have contributed to his own medical condition . Manganiello spent three years writing the book, which he described as documenting his "10-year search for answers" while expanding both geographically and backward in time .

Looking Forward

The actor expressed hope that sharing his story might provide comfort and inspiration to others facing similar health challenges. "If you're out there and you're suffering, then there's hope, and hopefully you'll get something out of it," Manganiello said in his video .

"Bloodlines" is scheduled for release on October 13 in print, Kindle, and audiobook formats. The memoir is now available for pre-order wherever books are sold . The book promises to explore themes beyond his medical crisis, including inheritance, masculinity, faith, ambition, and the identities people construct to endure hardship .

For Manganiello, what began as a terrifying health battle has transformed into what he considers his greatest adventure, offering him a new perspective on life, suffering, and the hidden histories that shape our present.
