When was i told that i had acid reflux/gerd i noticed my stomach pulse it got me really worried because i never noticed it does it mean aaa or nothing?

Rare...: It is extremely rare for a person in your age group to have AAA, unless you suffer of an ongoing cardiovascular condition which would be most likely congenital( before even born). Acid reflux, which is not life threatening , is most likely to happen depending on your symptoms. If you have not been examined do so with your regular doctor so you can get answer for all your concerns.

NO..: Noticing your pulse in the pit of your stomach is normal. Aortic aneurysm would be hardly likely at age 21, the risk increases with age, particularly a risk for male smokers over the age of 55. There is also a genetic component. First degree relatives and siblings of a patient with AA have a significantly increased risk of having the development of an AA.
