One of the most common questions expectant mothers ask before an ultrasound is:
“Should I drink a lot of water before my scan?”
The answer depends on the type of ultrasound and the stage of pregnancy.
Early Pregnancy (6–12 Weeks)
During early pregnancy, the uterus is still located deep within the pelvis.
A moderately full bladder can help improve visibility during a transabdominal ultrasound, making it easier to see the pregnancy and surrounding structures.
In some cases, your healthcare provider may recommend drinking water before the appointment.
Mid-Pregnancy and Beyond (18–22 Weeks and Later)
For anatomy scans and most ultrasounds after the first trimester, drinking large amounts of water is usually unnecessary.
By this stage, the uterus and baby are much larger and can typically be seen clearly without a full bladder.
In fact, an overly full bladder may cause discomfort during the examination.
Can Drinking Water Help the Baby Show Their Face?
Many parents hope that drinking extra water will help them get better ultrasound images.
However, a baby’s position is influenced more by factors such as:
- Fetal position
- Amniotic fluid volume
- Placenta location
- Timing of the scan
Drinking more water does not guarantee that your baby will cooperate for photos.

✔ Eat normally
✔ Stay normally hydrated

Final Thoughts
Whether you need to drink water before an ultrasound depends on your pregnancy stage and the type of scan being performed.
For many routine mid-pregnancy ultrasounds, extra water is not required.
When in doubt, always follow your healthcare provider’s instructions.
