It is commonly found in cholecystitis, gallbladder stones, liver cancer, etc. Patients may be accompanied by nausea, vomiting, aversion to oil, bitter mouth, yellow skin staining, fever and other symptoms. Ultrasound or CT examination of liver, gallbladder, spleen and pancreas as well as liver function tests are recommended to clarify the diagnosis. Second, colon disease. It is seen in colitis, colon polyps, colon cancer and intestinal obstruction, intestinal flatulence, intestinal spasm, etc. It is recommended to do standing abdominal plain film and, if necessary, colonoscopy to clarify the diagnosis. It is recommended not to apply strong painkillers until the cause is clear, but if the patient has more obvious pain, 654-2 can be given to relieve spasm and pain, or according to other symptoms of the patient. For example, when the patient has nausea and vomiting, no bowel movement, no defecation and no exhaustion may be a sign of intestinal obstruction. It is recommended to give an enema and observe the patient’s symptoms so that the condition will not be masked.
