Oscar-winning actress Lupita Nyong’o is using her global platform to speak out against a long-standing crisis in healthcare. She is highlighting how a historical focus on the male body has left women’s health in the shadows.

The Kenyan-born Mexican star, known for her roles in 12 Years a Slave and Black Panther, is now advocating for urgent research into uterine fibroids. She argues that the medical world has treated men as the "default" for far too long.

The 'Male Default' in Medicine

For decades, medical researchers and doctors operated under the assumption that findings from male subjects would apply to everyone. Nyong’o points out that this is simply not true.

Because drug dosages were traditionally designed around male weight and metabolism, women have faced significant risks. Statistics show that women are twice as likely as men to suffer serious side effects from certain prescription medications.

"Doctors and researchers assumed male bodies were the default, and that findings from men would apply to everyone. They don’t,Lupita Nyong'o said.

The consequences of this bias can be fatal. Nyong’o noted that some heart medications designed to save men’s lives can actually increase the risk of cardiac death in women.

The Silent Crisis of Fibroids

A primary focus of Nyong’o’s advocacy is the prevalence of fibroids. These are non-cancerous growths in the uterus that can cause severe pain and complications.

According to the actress, fibroids affect up to 80% of women.

Despite how common they are, they remain one of the most underfunded areas of medicine. This lack of research has led to a reliance on surgery. Fibroids are currently the leading reason for hysterectomies.

A Call for 'Overdue' Research

Nyong’o, who has previously shared her own personal journey with fibroids, is working with the Foundation for Women's Health to demand change. She insists that focusing on women’s health is not about asking for special treatment. Instead, it is about "catching up" after years of exclusion.

"More research specifically focused on women isn’t about special treatment. It’s about catching up,she added.

The actress is encouraging the public to support the #MakeFibroidsCount campaign. She is directing her followers to resources that fund specific research into women’s health issues.

By shining a light on these disparities, Nyong’o hopes to ensure that future medical breakthroughs are designed for everyone, regardless of gender. Research focused on women is no longer just a request; she argues it is a necessity that is deepy overdue.
