She had them taken out last winter.

In what she's called her "most personal post," Ashley Tisdale revealed that she had her breast implants removed last winter after experiencing unexplained "minor health issues" and striving to live a more "non-toxic life." In a lengthy Instagram caption, she explained that the removal allowed her to embrace her body and self and combat constant thoughts of feeling "less than."

Tisdale explained that she's had breast implants for years and that, at first, they did allow her to feel more comfortable in her body and more secure about how she looked. However, she notes, things started to get more complicated.

"As you know, I've been very open about my mental health journey and feel that this is equally important," she started. "Years ago I underwent breast enhancement surgery. Prior to the surgery, I constantly felt my body was less than, and thought this change would make me feel more whole and more secure about myself. And for a short period of time ... it did."

Tisdale noted that she struggled with "food sensitivities as well as gut issues" after her implants. And though she does not blame them explicitly, she did write that she consulted both "holistic and non-holistic doctors" and decided to have the implants removed. Tisdale noted that she'll offer up more information on a second account, @frenshe, a new endeavor that hopes to teach followers about "non-toxic living."

"This picture above was taken two months after my explant surgery and I think you can tell just how happy I am to finally be fully me," she wrote. "Over the years I've met with many holistic and non-holistic doctors and learned the importance of living a non-toxic life. I'm super excited to share with you what I've learned thus far, and would love for you to take this journey with me by following @frenshe, where we take an honest approach to our well-being and openly speak to health, beauty and everything in between."

She finished with a message about moving forward and allowing her past decisions to stay in the past: "I can't say I'm the proudest of the choices I made in the past but I don't regret it because it got me here today."

According to People, the Food and Drug Administration is investigating breast implant manufacturers after several reports linked breast implants to anaplastic large-cell lymphoma, a type of cancer. The FDA instructed manufacturers to add a warning to implants' packaging with explicit warnings of the potential dangers.
