Drinking alcohol one day and having an ultrasound the next day will generally have no effect. Drinking alcohol generally affects the blood aspect of the test because alcohol enters the blood system, whereas ultrasound does not involve the blood, so there is generally no significant effect. Ultrasound examination generally includes abdominal examination, that is, the liver, gallbladder, pancreas, spleen and abdominal cavity and other parts; gynecological examination, including the uterus, pelvis and ovaries, etc.; urinary examination, whether there are stones and tumors, etc.; the surface of the body masses and lesions, as well as limbs and cardiac vascular examination. In addition, there are many other things to be aware of during an ultrasound examination, and it is recommended to consult a specialist if necessary.
