• Amanda Seyfried said she suffered a "spinal" issue when she delivered her son last year
  • The actress shared that she has since recovered
  • Seyfried revealed she took self-care measures in order to prevent postpartum depression

Amanda Seyfried has opened up about the health struggles she experienced when she gave birth to her second child a year ago.

Seyfried, 35, recently spoke with People about the delivery of her baby boy, Thomas, now 1, last year. The actress, who also shares 4-year-old daughter Nina with husband Thomas Sadoski, 45, revealed that she faced "spinal challenges" that made the birth complicated.

"I had something that went wrong with my second birth. The baby was OK, but it was tricky and it was painful and it didn't have to happen, and it did so it added an extra level of trauma," the Oscar nominee told the outlet at the "A Mouthful of Air" screening at the Roxy Hotel in New York City Sunday night.

Seyfried also shared the challenges of delivering a child, which include the abrupt cessation of regular health care visits coupled with handling multiple medical invoices while recovering.

"I went to the doctor every week at the end of my pregnancy and all of sudden it's like, 'Bye, here's some hospital bills!' I mean, I kept receiving them and I'm still healing from something," she explained.

As for her current condition, the "Mamma Mia" star told People, "I'm OK. It was a very physical thing and it was a spinal thing, but I'm OK."

For her pregnancies, Seyfried took self-care measures in order to prevent postpartum depression, which she admitted she was "terrified of suffering from."

"I ended up doing a lot of CBT therapy before I had my first kid and then I was really lucky, I didn't suffer from any depression and I felt like I had won in some way," she explained. "It was hard, and it was so hard, the struggle, but it wasn't anything I didn't think I could handle. And with my second kid, that's partly because I was on my medication and I never got off of it."

The "Mean Girls" actress previously told Allure back in 2016 that she was taking medication for obsessive-compulsive disorder (OCD). "Yeah. I'm on Lexapro, and I'll never get off of it. I've been on it since I was 19," she said at the time.

During her chat with People, Seyfried shared how she and her husband managed to juggle their two children while also dealing with her health issues. According to the actress, her husband would look after their daughter while she fed their son. They also had people who could drive her to and from the hospital.

In 2018, Seyfried revealed in an interview with PorterEdit how motherhood changed her and affected her career. The "Jennifer's Body" star said she became picky when it came to her movie projects and would no longer wear thongs or do sex scenes.

Seyfried's latest movie, "A Mouthful of Air," hits theaters Friday.
