Diarrhea, also known as diarrhea, is a symptom. Diarrhea is not necessarily caused by liver cancer, but also caused by intestinal diseases, acute poisoning and systemic infection. Symptoms of liver cancer are more complicated. Early stage of liver cancer starts insidiously and lacks typical symptoms. When the disease develops to advanced stage, jaundice, ascites, vomiting, diarrhea and other symptoms will appear. This shows that liver cancer does not necessarily cause diarrhea. When there are intestinal diseases such as enteritis, colitis, dysentery, irritable bowel syndrome, etc., acute poisoning caused by accidental consumption of poisonous mushrooms, puffer fish, fish guts, etc., or systemic infections such as sepsis, typhoid fever, etc., diarrhea will also appear. This shows that diarrhea is not necessarily liver cancer. The causes of diarrhea are more complicated, so it is suggested that patients should consult the doctor in time to find out the causes of diarrhea, so as not to miss the condition.
