The term stomach cramps is nonspecific and is used to refer to a number of different symptoms or sensations. People often refer to a "stomachache" or "abdominal cramps" to refer to pain that is perceived anywhere in the abdominal area. As such, the list of potential causes is extremely varied. Organs of the abdomen include the stomach, small intestine, colon, liver, gallbladder, and pancreas, and problems or diseases of all of these organs may be the source of pain. Occasionally, pain may be felt in the abdomen even though it is arising from organs that are close to, but not within, the abdominal cavity, such as conditions involving the lower lungs, kidneys, uterus, or ovaries.
