When to come empty stomach?
All ultrasound examinations of upper abdomen or whole abdomen require you to come
empty stomach. This is essentially to see gall bladder in distended condition. However,
practically, we are able to see it well in most of the patients and as a rule, we
do not recommend empty stomach. But once in a while, if gall bladder is completely
contracted, we may suggest you to come empty stomach again to have a better look
at gall bladder. Coming empty stomach in the morning, however, helps in one more
way as there is less gas in abdomen which helps in better visualization.
When to come full bladder?
Generally all lower abdomen and whole abdomen examinations require full bladder.
Also examinations of KUB and early pregnancy (generally up to 3-4 months) will require
full bladder. Full bladder means you have to take lot of water at least 1-2 hrs
before examination and not pass urine. A well distended urinary bladder helps in
seeing uterus, ovaries and adnexa properly in females and prostate in males. It
also helps in seeing small stones in bladder and ureters in KUB examination. It
is important to note that an urge to pass urine does not indicate you are having
full bladder. A really full bladder will make you uncomfortable. We need you to
have full bladder, but you should be comfortable. For these examinations, come with
some margin to wait as your turn may not come immediately on reaching clinic.
Examination of children:
Examination of small children is difficult if they are crying. A well satisfied
child is less prone to crying. We do not normally recommend them to be kept empty
stomach except in some situations. Sometimes child may need to be sedated.
When you come in for your ultrasound examination for seeing the fetus well-being
Have a good meal 30 - 60 minutes prior to appointment. Drink 1 to 2 glasses of fruit
juice 20-30 minutes prior to the appointment unless otherwise ordered by your physician.
We would like your baby to be awake during your exam for more thrilling experience.
We would also like some fluids in your bladder to bring the baby’s head out of the
pelvis, but it does not need to be extremely full.
