Lena Dunham knows she is more fortunate than most when it comes to her health and well being.
The Girls star shared a pic on Thursday from her emergency hospitalization earlier this week, revealing the medical care was due to complications from her recent endometriosis surgery.
"Thank you for all the love & concern that's been pouring in since Tuesday," the 30-year-old filmmaker wrote. "Although I'm much healthier than I was a year ago, complications arose from my most recent endometriosis surgery."

Dunham followed the update with an acknowledgment of her access to healthcare, while nodding to the battle over Obamacare happening in Washington.
"When the healthcare of so many American women, especially our trans sisters, is at-risk- or already nonexistent- I am lucky to be in the position to seek help when I'm in pain," she wrote. "To those in that privileged spot- never forget that we are blessed and can pay it forward by supporting Planned Parenthood and LGBTQ clinics like Callen-Lorde with our ? and ⌚️."
"I also want to remind all the women suffering from chronic illness that we aren't weak- quite the opposite, actually," she added. "We do our jobs with skill even when we're struggling. We care families even when we can hardly care for ourselves. We serve major face on a red carpet when we feel like lying face down would be more appropriate."

"I'll always be proud of those Met Gala pics," Dunham continued, referencing her appearance at the fashion event before being rushed to the hospital. "Not just because I felt beautiful, surrounded by art and magic, hugging my best friend tightly, but because they're evidence that women contain steely multitudes. Just that morning @dianafalzone sued Fox after they took her off air for disclosing her endometriosis. But they're the ones who lost when they fired her, because everyone who's anyone knows that if you can battle chronic illness there's nothing you can't take on."
Following her hospitalization on Monday, a source told ET, "Lena is at home resting and doing well," adding, "As you know she's very public about her battles with endometriosis."
