What is the cause of abdominal distension and pain in lung cancer? Consider chemotherapy reaction

When lung cancer patients experience abdominal distension and pain, the first thing to consider is whether it is a reaction to chemotherapy. The second possibility is constipation, and the third possibility is abdominal metastasis.

Lung cancer is a disease of the respiratory system, and most of the time the symptoms are coughing, chest tightness, chest pain or shortness of breath. So, what is the cause of abdominal distension and pain in lung cancer?
Chemotherapy reaction <br/>If lung cancer patients take chemotherapy measures during the treatment process, it is very likely that the chemotherapy drugs will have a strong toxic effect on the patient's digestive tract, which may cause abdominal distension and abdominal pain in the patient. Of course, some patients may also experience vomiting blood or loss of appetite.
Constipation <br/>If the patient has not undergone chemotherapy but still has abdominal distension and abdominal pain, it may be caused by constipation. After all, if a normal person is constipated, he will have some abdominal discomfort to a certain extent. It’s just that lung cancer patients have a relatively poor physical constitution, so abdominal distension and abdominal pain will be more serious.
Abdominal metastasis <br/>If the patient has not undergone chemotherapy and the abdominal distension and pain are not caused by constipation, then it is necessary to consider whether it is abdominal metastasis. If the liver metastasizes to the retroperitoneal lymph nodes, it will cause abdominal distension and pain. At this time, further medical examinations and diagnoses must be performed before specific treatment measures can be taken.
