Some 75% of mothers with mental health problems do not get diagnosed or receive adequate treatment say the Maternal Mental Health Alliance.
Tuesday 3 May is World Maternal Mental Health Day focusing on raising awareness of maternal mental health issues so that more women will get treatment and fewer will suffer.
The Maternal Mental Health Alliance add that one in five new mothers experience some type of perinatal mood and anxiety order.
They say that it is important to declare a World Maternal Mental Health Day in order to give more visibility to the problem, combat social stigma and improve detection and treatment.
They add: “Women, as well as their family and friends, need to know the signs of maternal mental ill-health and that they are not alone. They can find help and support for perinatal mental health problems.”
The Alliance are encouraging people to tweet using #maternalMHmatters and contribute to the conversation.
