The IUFD medical abbreviation means intrauterine fetal demise, the clinical term for a fetus that has died while still inside the uterus. Some records spell out the D as death instead of demise, and both versions mean the same thing.
Families sometimes meet these letters in a hospital record, an ultrasound report or a portal summary after a loss, often at a time when they are already grieving. This page explains the term calmly and plainly: what it refers to, how it relates to the word stillbirth, how it appears in obstetric notes, and which nearby abbreviations look similar but mean something else. It is written for general understanding, not to explain any single person's care.

What the IUFD medical abbreviation refers to
IUFD describes a fetus that has died before birth while still in the uterus. The word intrauterine means inside the uterus, fetal refers to the developing baby, and demise is a formal word for death.
In the United States, fetal deaths are generally reported once a pregnancy has reached about 20 weeks, and losses later in pregnancy are commonly called stillbirths. Other countries and international bodies use different week cutoffs, such as 22, 24 or 28 weeks, so the exact boundary depends on where the record was written. A loss earlier in pregnancy is usually called a miscarriage, recorded as SAB for spontaneous abortion, a medical term that does not imply anything was done to end the pregnancy.
IUFD medical abbreviation in pregnancy notes
Obstetric notes follow a compact style. A single line often holds the pregnancy history, the gestational age and the finding.
| Part | Meaning |
|---|---|
| G2P1 | Second pregnancy, one previous birth |
| 32w by LMP | 32 weeks, dated from the last menstrual period |
| US | Ultrasound |
| IUFD | Intrauterine fetal demise |
| no cardiac activity | No heartbeat was seen on the scan |
In a handoff: "Admitted at 34 weeks with IUFD, plan induction, family has requested chaplain visit." Here the care team is passing on the finding, the plan for delivery and the family's wishes for support.
How it differs from similar abbreviations
Several obstetric abbreviations start with IU because they all describe something inside the uterus. Reading the last letters carefully avoids a serious misunderstanding.
| Abbreviation | Meaning |
|---|---|
| IUFD | Intrauterine fetal demise |
| IUGR | Intrauterine growth restriction, a fetus smaller than expected |
| IUP | Intrauterine pregnancy, a pregnancy confirmed to be in the uterus |
| IUD | Intrauterine device, a form of contraception |
| IUI | Intrauterine insemination, a fertility procedure |
Because IUD is also a well-known contraceptive device, many records now write IUFD in full or as fetal demise in patient summaries.
What the care record may include afterward
After this diagnosis, notes often list tests the team may offer to look for a cause, such as an examination of the placenta, blood tests and genetic testing, with the family's consent. A cause is not always found. Records may also include terms such as induction of labor, delivery details and plans for follow-up visits.
Many hospitals have bereavement teams, social workers or chaplains, and notes may mention these services. The language in the chart is clinical by design, and it is meant to record facts accurately rather than to describe feelings.
Why clinicians use this formal term
Medical records need a precise, standard term that coders, other clinicians and reporting systems understand the same way. IUFD tells the next reader exactly what happened and where, which matters for follow-up care in a future pregnancy and for official fetal death reporting.
In conversation with families, clinicians usually use gentler and plainer words. Seeing the abbreviation in writing does not reflect how the staff view the loss. Other formal condition terms used in records are explained in the diagnosis abbreviations section, and a related monitoring test, the NST or nonstress test, appears in many later pregnancy notes.
Questions families may want to ask
If this term appears in your own record, it is reasonable to ask the care team to explain any part you do not understand.
- What tests were done, and when will results be available?
- Was a cause identified, or is the review still in progress?
- What follow-up appointments are planned for my own recovery?
- What support services are available through the hospital?
This information explains a medical term in general. Your obstetric provider or nurse can talk through your own records and answer questions about your health and any future pregnancy.
Frequently asked questions
What does IUFD mean in pregnancy?
IUFD means intrauterine fetal demise, a fetus that has died while still inside the uterus. It is the clinical term found in hospital records and ultrasound reports.
Is IUFD the same as stillbirth?
They overlap. Stillbirth usually describes a fetal death later in pregnancy, and an IUFD at that stage is recorded as a stillbirth. The exact week cutoff varies between countries and reporting systems.
What is the difference between IUFD and IUGR?
IUGR means intrauterine growth restriction, a fetus that is growing more slowly than expected but is alive. IUFD means the fetus has died. The letters look alike, so records should be read carefully.
Does IUFD mean the same as miscarriage?
Not quite. Miscarriage usually refers to a loss earlier in pregnancy, before about 20 weeks in the United States. IUFD is typically used for losses after that point, though usage varies by setting.
Why does my record say demise instead of death?
Demise is simply a formal medical word for death. Records may use either IUFD for demise or IUFD for death, and both mean the same thing.
