Abdominal bloating is the result of the gastrointestinal (GI) tract being filled with gas or air. A bloated stomach usually makes one feel swollen or tight in and around the abdomen. If you have a bloated stomach, you might also be experiencing pain, frequent burping, rumbling in the abdomen, excessive gas or belching.

Aorta is the largest blood vessel in the body. Although a durable and a tough workhorse, it can sometimes weaken due to a formation of a bulge. This is called aortic aneurysm. It is the dilation or enlargement of the aorta. In some instances, the enlargement can be greater than 1.5 times the normal size.
