Many pregnant individuals experience a sensation of a pulse or “heartbeat” in their stomach. This is a common and normal physiological experience during pregnancy. This article explains the reasons behind this sensation, clarifies how it differs from a baby’s heartbeat, and provides guidance on when to consult a healthcare provider.
Understanding the Sensation
The pulsating sensation felt in the stomach during pregnancy is the mother’s own pulse, not the baby’s, and becomes more noticeable due to significant physiological changes. Total blood volume increases substantially, by approximately 30% to 50% over the course of pregnancy, leading to a more forceful flow through major arteries. A large artery, the abdominal aorta, runs down the middle of the body in the abdomen. As the uterus grows, it can also exert pressure on this aorta, which further contributes to the sensation of a strong pulse in the stomach area. This sensation can be particularly noticeable when lying down or after eating, as blood flow is directed towards the digestive system.
Distinguishing from Your Baby’s Heartbeat
It is common to mistake the felt pulse for the baby’s heartbeat, but it is highly unlikely to be felt externally. A baby’s heartbeat is considerably faster than an adult’s, typically ranging from 110 to 160 beats per minute, often described as a rapid “galloping” or “train-like” sound. An adult’s resting heart rate is generally between 60 and 100 beats per minute. The baby’s heart is small and is protected by layers of amniotic fluid, the amniotic sac, the uterine wall, maternal muscles, and skin, making it very difficult to perceive as a distinct external pulse. Healthcare providers use specialized equipment, such as a Doppler ultrasound device, to monitor a baby’s heartbeat, amplifying the sound to be heard clearly.
When to Consult Your Healthcare Provider
While feeling a pulse in the stomach during pregnancy is generally a normal occurrence, medical advice should be sought in specific situations. Always discuss any new or unusual symptoms with a healthcare professional. Contact your doctor or midwife if the pulsating sensation is accompanied by other concerning symptoms. These include severe abdominal pain or cramping, vaginal bleeding, severe dizziness, a rapid heart rate, shortness of breath, or any sudden changes in the pulse’s intensity or character. Reaching out to a healthcare provider can provide reassurance and rule out underlying conditions.
