I have been noticing visible pulse in upper abdomen. I got usg and CECT abdomen done to rule out aneurysm. Both indicate that everything is normal. However, I am still unable to find a reason for the pulsation in abdomen. It's really evident when laying down. I am not particularly lean in the stomach area. I got some fat in the belly region and have grade 1 fatty liver.  I am 5.10 tall and weigh 71 kgs. Please advise. Thanks in advance.
