American model and beauty entrepreneur Hailey Bieber has opened up about her struggles with premenstrual dysphoric disorder (PMDD) following the birth of her first child, revealing how the experience deepened her interest in women’s health and the need for more medical research into conditions affecting women.
The 29-year-old wife of Canadian pop star Justin Bieber discussed her experience in an interview with Women’s Wear Daily (WWD), published in October 2026, explaining that her health challenges after becoming a mother made her realise how little attention some women’s health conditions receive.
Hailey, who welcomed her son, Jack Blues Bieber, with Justin in August 2024, said she experienced PMDD after childbirth.
“After I had my son, I struggled with that a bit, and there’s just not a lot of conversation or research around it,” she said.
She explained that speaking publicly about her experience was important because conversations among women facing similar challenges could help reduce feelings of isolation.
“Conversation, for me personally, makes me feel less alone. When we can identify with each other and have conversations relating to each other and talking about the things we’re dealing with and struggling with, I do think it makes it feel like less of a lonely journey,” she added.
The model had previously discussed her diagnosis during an appearance on the SHE MD podcast in March 2026. She explained that she noticed a significant difference in the intensity of her premenstrual symptoms after becoming a mother.
According to Hailey, the emotional experience became particularly overwhelming in the days leading up to her menstrual period.
She recalled experiencing intense thoughts and feelings that made ordinary situations appear much more serious than they otherwise would.
Hailey said she initially struggled to understand why the symptoms felt considerably worse than the premenstrual symptoms she had experienced before pregnancy. She eventually received a PMDD diagnosis approximately six months after giving birth.
Premenstrual dysphoric disorder is a severe condition associated with the menstrual cycle. Although it shares similarities with premenstrual syndrome (PMS), its emotional and physical symptoms can be significantly more intense and interfere with everyday activities, relationships and work.
Symptoms may include severe irritability, anxiety, depression, mood changes, fatigue, difficulty concentrating, sleep disturbances and physical discomfort. They typically occur during the period leading up to menstruation and improve after the period begins.
Hailey’s decision to speak about the condition comes as her beauty company, Rhode, strengthens its involvement in women’s health advocacy.
In October 2026, the brand announced a $5 million commitment over three years through a partnership with the Foundation for Women’s Health, a non-profit organisation working to address gaps in medical research and healthcare innovation.
The funding represents Rhode’s largest philanthropic investment to date and is expected to support research, education and innovation in areas that have historically received insufficient attention.
The partnership will focus on several areas of women’s health, including pregnancy, postpartum care, autoimmune conditions and polyendocrine metabolic ovarian syndrome (PMOS).
One million dollars from the commitment will establish the Foundation for Women’s Health Evergreen Fund, an investment initiative intended to support companies developing diagnostic tools and treatments for women’s health conditions.
The foundation’s founder and executive director, Katy Brodsky Falco, welcomed the partnership, describing the investment as an important opportunity to bring greater attention and resources to areas of healthcare that have historically been overlooked.
Hailey explained that her interest in women’s health was influenced not only by her personal experience but also by the challenges faced by people close to her.
She mentioned that her sister experiences PMOS, while several of her friends have dealt with endometriosis and other health conditions affecting women.
The entrepreneur said she felt frustrated by the lack of research, awareness and public conversations surrounding such conditions.
Motherhood has also been a significant part of Hailey’s personal journey. She and Justin welcomed their son, Jack Blues, in August 2024, marking a new chapter in their marriage, which began in September 2018.
Although the couple have occasionally shared family moments with the public, Hailey has increasingly used interviews and her business platform to discuss the realities of pregnancy, childbirth and postpartum health.
Her latest comments have renewed conversations about PMDD and the importance of recognising women’s health challenges rather than dismissing severe symptoms as ordinary PMS.
While Hailey’s experience has helped bring attention to the condition, her broader message is that more research, accessible information and open conversations are needed to help women understand and manage health challenges that can significantly affect their lives.
