About 1 in 8 new mothers in the United States experience postpartum depression symptoms, according to the Centers for Disease Control and Prevention. Some women develop symptoms soon after giving birth, but others struggle with depression months later.
Postpartum depression can leave a mother feeling constantly anxious, exhausted or disconnected from her baby. Some women lose interest in activities they previously enjoyed. Others feel guilty because they are not experiencing the happiness everyone expected after childbirth.
Researchers have also found that recorded diagnoses are increasing. A study published in JAMA Network Open in November 2024 examined 442,308 births in Southern California and found that documented postpartum depression rose from 9.4% in 2010 to 19.0% in 2021.
Digital pregnancy tools such as Femia allow women to record symptoms and changes during pregnancy. However, an app cannot diagnose depression or replace a medical appointment, and users should review how their personal health information is handled.
Postpartum depression is part of the wider problem of anxiety and depression in America, but the physical and emotional changes surrounding childbirth give it particular challenges.
How Common Is Postpartum Depression?
We found that 12.5% of women who have recently given birth experience postpartum depressive symptoms. Other research puts the figure closer to 1 in 7 mothers, or 14.3%.
The StatPearls medical review discusses the 1-in-7 estimate. Published studies have also reported rates ranging from roughly 10% to 20%, depending on the population and how depression is measured.
Some researchers ask mothers to complete questionnaires about their symptoms. Others examine medical records to count formal diagnoses. A woman who experiences depression but never speaks to a doctor might appear in a questionnaire study but not in medical records.
Timing changes the results too. A mother who feels fine during her six-week checkup could develop symptoms four months after delivery.
You might also encounter annual estimates of 600,000 women experiencing postpartum depression or 900,000 experiencing a wider range of mental health problems following pregnancy, including pregnancy loss. Neither figure is established as a current national count by a single clearly identified study.
Women who experience miscarriage or stillbirth can also develop depression. However, combining those cases with depression after a live birth produces a wider estimate covering a separate population.
Postpartum Depression and the Baby Blues
Many women experience emotional changes during the first days after childbirth. Doctors call this the baby blues, which can involve crying, irritability and sudden changes in mood.
The baby blues generally improve within two weeks. Postpartum depression lasts longer or causes symptoms serious enough to interfere with daily life.
A mother experiencing severe distress should not wait two weeks before seeking medical help.

Some Mothers Never Receive a Diagnosis
A mother might tell her doctor that she feels fine six weeks after giving birth. Two months later, she starts struggling with anxiety, insomnia or persistent sadness. If she has no further appointments, those symptoms might go unnoticed.
Some postpartum mental health resources estimate that nearly half of affected mothers remain undiagnosed. However, that claim lacks a clearly identified national study and reporting period, so it should not be treated as a confirmed current percentage.
There are several reasons women miss treatment. Some worry about being judged, particularly if they struggle to bond with their baby. Others cannot afford appointments or find a mental health professional nearby.
The American College of Obstetricians and Gynecologists advises healthcare professionals to screen for depression and anxiety during pregnancy and after delivery.
Screening should also lead to follow-up care. Identifying symptoms accomplishes little if the mother cannot arrange an assessment or treatment afterward.
What Increases the Risk of Postpartum Depression?
Previous depression or anxiety is among the strongest known risk factors. Women who experienced postpartum depression after an earlier pregnancy also face a higher chance of developing it again.
Still, postpartum depression can affect women who have never experienced a mental health problem.
The existing video discusses postpartum depression and its risk factors. It is included as supplementary material, rather than as the source for the statistics in this article.
Hormones, Sleep and Physical Recovery
Estrogen and progesterone levels fall sharply after delivery. Hormonal changes can contribute to depression in susceptible women, although they do not explain every case.
Sleep deprivation can make symptoms harder to manage. Nighttime feeding and repeated interruptions leave many parents exhausted, and persistent insomnia deserves medical attention.
Doctors also consider thyroid problems because postpartum thyroiditis can produce fatigue, irritability and depression-like symptoms.
Family History and Financial Pressure
A personal or family history of depression or bipolar disorder helps doctors identify women who may benefit from closer monitoring. Some mental health conditions also begin earlier in life, as discussed in our coverage of mental health disorders among adolescents.
Financial pressure adds another burden after childbirth. Medical expenses, childcare costs and lost income can make an already exhausting period harder.
A difficult delivery or serious complications affecting the mother or baby can also increase emotional distress. Younger mothers sometimes face additional financial challenges, although age alone does not determine who develops depression. Changes in maternal age are also visible in U.S. birth rate statistics.
Postpartum Depression Rates by Race and Ethnicity
The California study involving 442,308 births found that recorded postpartum depression increased across every racial and ethnic group examined.
Researchers led by Nehaa Khadka examined medical records from Kaiser Permanente Southern California. Their paper, Trends in Postpartum Depression by Race, Ethnicity, and Prepregnancy Body Mass Index, was published in 2024. The study DOI is 10.1001/jamanetworkopen.2024.46486.
| Group | 2010 | 2021 | Relative Increase |
|---|---|---|---|
| White | 13.5% | 21.8% | 61% |
| Black | 9.2% | 22.0% | 139% |
| Hispanic | 8.9% | 18.8% | 111% |
| Asian/Pacific Islander | 3.6% | 13.8% | 283% |
Source: Khadka et al., JAMA Network Open, 2024. Figures describe documented postpartum depression within the California healthcare system, not nationwide prevalence. Relative increases are calculated from the displayed rates.
Asian and Pacific Islander patients experienced the largest relative increase, rising from 3.6% to 13.8%. Black patients reached 22.0% in 2021, slightly above the 21.8% recorded among White patients.
Higher diagnosis rates do not automatically mean depression itself became more common at the same pace. Improved screening, medical documentation and access to care can also change the numbers.
Research published in the American Journal of Obstetrics and Gynecology has also examined postpartum mental health across patient groups. The figures in the table, however, come from the 2024 JAMA study.
Postpartum Depression Also Affects Fathers
About 1 in 10 fathers experience depressive symptoms during the period surrounding childbirth, according to a 2010 meta-analysis published in JAMA.
The researchers examined 43 studies involving 28,004 participants and estimated paternal depression prevalence at 10.4%, with a 95% confidence interval of 8.5% to 12.7%. The studies covered pregnancy through the first year after birth, rather than fathers during one fixed month.
UT Southwestern Medical Center also explains how paternal depression can appear as anger, withdrawal or increased alcohol use rather than obvious sadness.
Symptoms deserve attention when they persist or interfere with work, relationships or caring for a child. Depression affecting one parent can also place additional strain on the other.
Adoptive Parents Can Experience Depression Too
Adoptive parents sometimes experience depression after a child joins the family. New responsibilities, interrupted sleep and emotional pressure can affect parents regardless of how their family was formed.
The MGH Center for Women’s Mental Health has discussed research on post-adoption depression, including studies involving Purdue University researchers.
Reported rates vary considerably because studies examine separate groups and use different questionnaires. A single percentage would give readers more certainty than the available research supports.
How Breastfeeding Affects Postpartum Depression
Some studies report lower depression rates among women who breastfeed. However, that does not prove breastfeeding itself prevents depression.
A woman who is already depressed might stop breastfeeding because feeding becomes difficult or exhausting. Pain, problems with latching and worries about milk supply can also increase stress.
A research review on breastfeeding and maternal mental health explains why the relationship works in both directions.
Hormones such as oxytocin and prolactin are involved in breastfeeding, but feeding experiences vary widely. The USDA also offers information about low milk supply and breastfeeding support.
Mothers who cannot breastfeed or decide to use formula still deserve proper mental health care. Feeding difficulties should never prevent someone from seeking treatment for depression.
When Postpartum Depression Becomes a Medical Emergency
Postpartum depression is usually associated with sadness, anxiety, exhaustion and difficulties managing daily life. Most affected mothers do not become violent.
Postpartum psychosis is a separate and much rarer psychiatric emergency. A 2018 clinical review by Lauren M. Osborne estimates that it affects 1 to 2 women per 1,000 births.
Those figures come from medical research rather than a current national count. Symptoms can include hallucinations, delusions, severe confusion and major changes in behavior.
A person experiencing psychosis may lose the ability to judge what is real. Emergency assessment is necessary because the condition can endanger both the mother and her baby.
The Lindsay Clancy Case Raised Questions About Postpartum Mental Healthcare
In January 2023, three young children died at their family home in Duxbury, Massachusetts. Their mother, Lindsay Clancy, was charged with murder.
Her defense argued that she had experienced postpartum psychosis and was not criminally responsible for the killings. Prosecutors challenged that argument, saying the evidence showed she understood her actions.
The case attracted national attention. In August 2026, hundreds of supporters gathered outside a Massachusetts courthouse, with some speaking publicly about their own experiences of postpartum mental illness.
WBUR reported on the August demonstration, where supporters called for greater recognition of serious mental health problems following childbirth.
The trial ended without a verdict. On September 4, 2026, the judge declared a mistrial after jurors failed to agree on criminal responsibility. WBUR’s courtroom report described the deadlocked jury and the decision.
Clancy’s defense has subsequently challenged aspects of the proceedings, and her legal responsibility remains unresolved. The criminal allegations, the deaths of the children and the medical testimony deserve separate consideration.
The case also brought attention to postpartum psychosis, which should not be confused with ordinary postpartum depression. Depression does not, by itself, establish that someone is violent or unable to recognize their actions.
When Should Someone Seek Treatment?
Persistent sadness, severe anxiety, hopelessness or difficulty managing everyday activities are reasons to contact a doctor or mental health professional. Symptoms can appear months after childbirth, so the absence of problems during an early postpartum appointment does not rule out later depression.
Treatment commonly includes psychotherapy, medication or a combination of the two. A clinician may also investigate thyroid disease, severe insomnia or another medical problem contributing to the symptoms.
Women who are breastfeeding should discuss medication choices with their prescriber instead of stopping treatment on their own. According to the National Library of Medicine’s LactMed review of sertraline, sertraline is generally considered a preferred antidepressant during breastfeeding because infant exposure is usually low.
The LactMed review of paroxetine also identifies it as one of the preferred options. The MGH Center for Women’s Mental Health explains that treatment decisions should take account of the mother’s symptoms, previous medication response and the health of the baby.
Thoughts of suicide, fears of harming a baby, hallucinations or severe confusion require immediate medical assessment. In the United States, 911 is available for immediate emergencies, and the 988 Suicide & Crisis Lifeline provides crisis support.
Frequently Asked Questions
Can Postpartum Depression Start Months After Birth?
Yes. Some mothers develop symptoms well after their first postpartum appointment. Persistent depression, severe anxiety or difficulty functioning deserves medical attention even when the first weeks after delivery went smoothly.
Can Untreated Postpartum Depression Last for Years?
Depression can continue for months and become persistent without appropriate care. Earlier treatment can reduce the time a person spends experiencing severe symptoms and help restore daily functioning.
Does Hormonal Birth Control Affect Postpartum Depression?
Researchers have studied hormonal contraception and mood, but the findings vary by method and individual medical history. A clinician can help a woman with previous depression compare available birth control methods and discuss possible effects on mood.
