The suicide rate among women in some of the poorest parts of Dublin is reportedly is matching male numbers for the first time.
An HSE memo seen by The Irish Times shows half of the suspected deaths by suicide in the Dublin South Central area last year were women.
Psychiatric teams say no other areas are reporting the same levels.
Traditionally, suicide has been more prevalent amongst men in Ireland. 2016 data shows men account for almost 80% of deaths by suicide.
In total, 37 people are believed to have taken their own lives in Clondalkin, Tallaght and Ballyfermot last year.
Most of the women who died were in their 20s and 30s, had young chilren, and were from very disadvantaged backgrounds.
