The appearance of a beating, heart-like condition around the navel is relatively common in clinical practice. Sometimes it is very easy to find, especially in people who have a relatively thin body. In fact, this is due to the fact that there is a relatively large artery, the abdominal aorta, around the human belly button to the left. It fluctuates and beats at the same frequency suitable for the heart, so often a beating lump is felt around the navel, which is actually a normal physiological phenomenon. However, some abdominal aortic aneurysms may also occur, and the best way to prevent the possibility of abdominal aortic aneurysm or arterial entrapment is to do an abdominal color ultrasound exploration after feeling the beating mass. So when there is a beating around the belly button that fluctuates like the heart, there is no need to worry too much. Going to a regular hospital for an ultrasound of the abdomen will basically solve the problem and find the real cause.
