There are many causes of abdominal pain, ranging from life-threatening emergencies to chronic functional disorders and dysfunctions of certain organs and systems. For people who have not studied medicine, it is relatively difficult to identify which organ is the problem. Some older patients may have experience, such as abdominal pain with nausea and acid reflux, which may be thought to be a problem of the stomach; or some abdominal pain with loose stools and changes in the frequency of stools, which may be thought to be a problem of the intestines. Another example is annual medical checkups that reveal biliary stones, abdominal pain in the upper right and upper middle abdomen that radiates to the back, or even fever and yellow eyes, which may be biliary tract problems. Some abdominal pains are deeper in location, a band of pain, colic and radiating to the lower abdominal urethra, redness in the urine, may be renal colic, stones in the ureter, etc. In general, it is still difficult to identify the organs associated with abdominal pain without medical knowledge. Most abdominal pain, especially chronic abdominal pain, is a gastroenterological problem. Of course, some patients with abdominal pain who are older and have diabetes mellitus and hypertension, and whose gastroscopy, abdominal ultrasound, and CT examination reveal that the digestive system is fine, still have boring pain, which may be an atypical heart problem. Therefore, abdominal pain is a very complex condition and it cannot be asserted which diseases are involved, but should be analyzed specifically.
