For some women, the two-week luteal phase of their menstrual cycle can be extremely disruptive and life altering. PMDD or Premenstrual Dysphoric Disorder is mental health disorder directly linked to regular hormonal fluctuations that take place during a cycle. People living with PMDD can experience anger, anxiety, severe depression, and even suicidal thoughts which then stops shortly after menstruation begins. Two women, Shariya in the US and Janna in Germany tell us how PMDD has impacted them.

There’s very little scientific research about why PMDD happens and the signs or symptoms can be missed by doctors. We hear from BBC Health Reporter Ruth Clegg, who’s been reporting on how social media has shifted perceptions of the disorder, and led to changes around how doctors screen for symptoms.

If you are affected by any of the issues in this episode, or suffering distress or despair and need support, you could speak to a health professional, or an organisation that offers support. Details of help available in many countries can be found at Befrienders Worldwide. www.befrienders.org
