The abdomen is the area of the body between the thorax and the pelvis and includes the belly, stomach, or midriff and all of the organs and structures within it. Because the abdomen contains organs belonging to the digestive tract, urinary system, and other systems, it is prone to a wide variety of illnesses and conditions. Many of the more serious conditions that affect the abdomen directly inhibit or disrupt numerous essential processes.


1. Viral Gastroenteritis

One of the more minor conditions of the abdomen, viral gastroenteritis causes watery diarrhea, abdominal cramps, vomiting, and nausea. Many people refer to the condition as the stomach flu. Depending on the cause, viral gastroenteritis may appear a few days after the infection begins, and severe cases can last over a week. Generally, there is no treatment for viral gastroenteritis. Over-the-counter medications may soothe the symptoms, but the condition should resolve in a matter of days.
