Cancer patients vomit after eating. What's going on?

Vomiting generally refers to vomiting. Cancer patients vomiting after eating may be caused by chemotherapy side effects, tumor compression, cancer cell proliferation and other factors. Specific analysis is as follows:

1. Chemotherapy side effects

Chemotherapy drugs enter the human body, which will stimulate gastrointestinal smooth muscle, leading to gastrointestinal smooth muscle contraction and spasm, nausea and vomiting.

2. Tumor compression

part of the tumor may be located near the digestive tract, such as esophagus, stomach or intestinal tract. Tumor growth will compress or hinder the normal passage of food, leading to nausea and vomiting.

3. Cancer cell proliferation

If cancer cells spread to gastrointestinal sites, resulting in gastrointestinal mucosa damage, it will affect digestive function, promote gastrointestinal motility hyperactivity, nausea, abdominal distension, loss of appetite and vomiting.
