A fundal massage is a hands-on technique performed on your lower abdomen after childbirth to help your uterus contract and prevent heavy bleeding. A nurse or midwife presses on and massages the top of your uterus (called the fundus) through your belly to encourage it to firm up. It’s one of the most common procedures in postpartum care, and nearly every person who delivers vaginally or by cesarean will experience it at least once in the hours after birth.
Why It’s Done
After you deliver the placenta, the uterus needs to clamp down on itself to close off the blood vessels where the placenta was attached. When the uterus stays soft and relaxed instead of contracting, a condition called uterine atony, those blood vessels keep bleeding. Uterine atony is the single most common cause of serious postpartum hemorrhage, which is heavy bleeding in the first 24 hours after delivery.
Fundal massage works by physically stimulating the uterine muscle to contract. The pressure also triggers the release of natural compounds called prostaglandins in the uterine tissue, which promote further contraction. The International Confederation of Midwives and the International Federation of Gynaecologists and Obstetricians jointly recommend routine massage of the uterus after the placenta is delivered.
How the Massage Is Performed
The provider places one hand just above your pubic bone to stabilize the lower part of your uterus. With the other hand, they start at your belly button level and use the flat part of their fingers to feel for the top of the uterus. Once they locate it, they massage the fundus in a circular motion. If the uterus feels soft or spongy (clinically described as “boggy”), the provider continues massaging until it firms up into a hard, grapefruit-like shape. That firmness signals the uterine muscle is contracting properly.
The check takes only a minute or two when the uterus responds quickly. If the uterus stays soft despite massage, that alerts the care team that something more may be needed, such as medication to help the uterus contract.
How Often It Happens After Birth
In the first hour or two after delivery, your nurse will check your fundus frequently, often every 15 minutes. The checks gradually space out as your condition stabilizes. In a Cochrane review trial involving 200 women, massage performed every 10 minutes for 60 minutes after delivery of the placenta reduced blood loss and cut the need for additional contraction medications by roughly 80%. At 60 minutes, women who received regular massage lost an average of about 77 mL less blood than those who didn’t.
During your hospital stay (typically one to three days), providers will continue pressing on your abdomen periodically to check that the fundus is descending as expected. Each day, the top of the uterus should sit a little lower in your belly as it shrinks back toward its pre-pregnancy size, a process called involution.
What It Feels Like
There’s no way around it: fundal massage can be quite painful, especially in the first few hours after birth. Many people describe it as intense cramping or deep pressure that catches them off guard. The sensation is similar to strong labor contractions and typically peaks for about five minutes before easing. If you’ve had previous pregnancies, the cramping (called afterpains) tends to be even stronger because the uterus has to work harder to contract back down.
Breastfeeding can intensify the cramping because nursing triggers the release of oxytocin, which causes the uterus to contract. Some strategies that help manage the discomfort include slow breathing and relaxation exercises (the same kind used during labor), lying on your stomach with a pillow under your lower belly, walking when you’re able, and taking an over-the-counter pain reliever like ibuprofen if your provider has cleared it.
How Effective It Is
When used on its own, fundal massage clearly reduces blood loss in the first hour after delivery. The Cochrane review found that at 30 minutes post-delivery, women receiving massage had measurably less bleeding than those who didn’t. The need for additional contraction medications dropped significantly in the massage group.
The picture changes, though, when massage is combined with standard contraction medications like oxytocin (which most hospitals administer routinely). In that scenario, adding massage on top of the medication did not show a statistically significant further reduction in serious hemorrhage. This suggests that for women already receiving medication, massage may serve more as a monitoring tool: a way to physically check that the uterus is staying firm, rather than as the primary prevention measure.
Risks of the Procedure
Fundal massage is generally safe, but improper technique carries real risks. Applying too much downward pressure on a relaxed uterus is one of the two most commonly cited causes of uterine inversion, a rare but serious complication where the uterus partially or fully turns inside out. Providers are trained to avoid pushing the uterus downward and instead focus on circular massaging motions. Overly aggressive pressure with the fingertips can also, in extreme cases, risk perforating the uterine wall.
For the patient, the main “risk” is significant discomfort. Bruising of the abdominal tissue is possible if repeated firm massage is needed over several hours, particularly after a cesarean delivery where the incision site adds to the soreness. If your uterus doesn’t firm up with massage alone, your care team will move to other interventions, starting with contraction medications and escalating from there if bleeding continues.
What a “Boggy” Uterus Means
You may hear your nurse say your uterus feels “boggy.” This means the uterine muscle is soft and not contracting the way it should. A boggy uterus paired with heavy bleeding is the textbook sign of uterine atony and prompts immediate action. The first step is always fundal massage. If the uterus firms up and stays firm, the situation is typically resolved. If it repeatedly softens again or doesn’t respond to massage at all, that signals a more stubborn case of atony that requires medication or further intervention.
A firm fundus, by contrast, feels like a hard ball roughly the size of a grapefruit sitting behind your belly button. That’s exactly what the care team wants to feel each time they check. Over the following days and weeks, the uterus continues shrinking until it returns to roughly its pre-pregnancy size, usually around six weeks postpartum.
