I recently got out of the Marine Corps (No I never did that when I was in). But before boot camp, I was a typical 15-18 year old who dabbled in everything under the sun, minus needles and freebasing ...
No, never. Either your heart has prolapsed into your stomach or you have gastrointestinal problems. If it is uncomfortable see a doctor.
may be young for aneurysm,but,can happen..see MD for ultrasound...............
Yes. Absolutely. Don't let others' ignorance cause you to panic.
Your aorta runs just left of midline in your abdominal cavity. Especially if you are thin, you will be able to feel this pulsation, and will be able to follow its path through your abdomen.
What these other people are referring to is an abdominal aortic aneurysm (AAA). In this, the wall of the aorta stretches out in one specific spot, causing a "balloon" to form. This balloon will have a "pulse" to it as well, is easily palpable, and is a primary sign of this condition.
However, a AAA will present as an AREA of pulsating, not just a "spot". It is often described as a "pulsating mass". Now, if THIS is the case, it's possible that you have a AAA. But it usually accompanied by other symptoms, such as low blood pressure or dizziness.
Most people don't feel the pulsing there. If you ever feel pain from it go to the emergency room immediately. Some people do feel the pulse there though. That's the descending abdominal aorta, one of the largest blood vessels in your body. You shouldn't feel the pulsing all the time, but on occasion isn't that abnormal.
Yes, that is quite common, especially if you are thin. There is a large vein that travels through your abdomen and returns blood to the heart. If your stomach is empty, or you are just very thin, you might feel (or see!) your heartbeat in your stomach. It's normal, don't worry about it. If I rest something on my stomach while I'm lying down the thing I rested on my stomach will bounce around to my heartbeat. LOL.
Hope that helps.
