What causes pain on the left side of the abdomen?

Abdominal pain is very common, but when treating it, you must find the cause. If you have pain on the right side of your belly, you will think of appendicitis or gallstones, etc. However, some people may have pain on the left side of their belly, which requires a detailed examination, because there are many organs on the left side of the belly. So what is the cause of the pain on the left side of the belly?

First, what is the reason for pain on the left side of the abdomen? Pain in the upper left abdomen may be caused by the stomach, spleen, pancreas, left kidney, or left large intestine; pain in the lower left abdomen may be caused by the sigmoid colon, left ovary and fallopian tube, left ureter, etc.; if it is pain around the navel, it mainly indicates a small intestine disease. In addition, sometimes there may be widespread pain throughout the abdominal cavity. This is usually caused by inflammation of the peritoneum due to irritation for some reason, such as ulcer perforation, ectopic pregnancy rupture, and internal bleeding.

Second, it is worth noting that some abdominal pain will shift with the influence of the lesion. For example, the pain starts in the center of the upper abdomen, gradually moves to the lower right within 24 hours and becomes more and more painful. This is an important sign of appendicitis. The pain was originally in the upper right corner and gradually extends to the bottom of the right rear shoulder blade. This may be a problem with the gallbladder or gallstones.

Third, the causes and effects of abdominal pain can be mild or severe. When abdominal pain occurs, in order to accurately grasp the cause, patients should pay more attention to the pain condition to facilitate the doctor's diagnosis, including the location of the pain, time, nature of the pain, whether it is accompanied by other symptoms, factors affecting the change of pain, etc. Whether abdominal pain is accompanied by other symptoms is also one of the key points in determining the cause of the disease. For example: diarrhea may be caused by gastrointestinal inflammation; constipation may be caused by fecal obstruction; vomiting should be considered as intestinal obstruction or inflammation; changes in bowel habits may be caused by lesions in the large intestine; jaundice, fever and other symptoms may be caused by bile duct or liver lesions; frequent urination, difficulty urinating, nocturia, etc. should be considered as problems with the bladder or urethra. These different symptoms that appear along with the pain can help to distinguish the true cause of abdominal pain.
