Liver cancer patients’ left lower abdominal pain after eating and pulling will not hurt anymore, which is usually related to gastrointestinal flatulence, hepatic ascites, metastatic spread of cancer cells and other factors. 1. Gastrointestinal flatulence: it is mostly related to irrational diet, such as eating too much or eating too greasy, which will affect gastrointestinal peristalsis and lead to gastrointestinal flatulence, which is not digested all the time, and will cause abdominal pain, and the symptom will be relieved after defecation. 2. Hepatic ascites: when the condition of liver cancer worsens and develops to advanced stage, causing hepatic ascites, it will lead to abdominal distension and abdominal pain, but the symptoms will be relieved after defecation. 3. Metastasis and spreading of cancer cells: If the liver cancer is in the middle stage or advanced stage, the cancer cells will metastasize and spread through the distal region, which will easily cause cancer pain, including abdominal pain and lumbar pain, etc., which can be relieved after defecation in some patients. When diagnosed with liver cancer, patients should carry out treatment as early as possible. If there are symptoms of lower abdominal pain, patients should take analgesics, such as aspirin and morphine, as prescribed by doctors to avoid the development of the disease.
