Reasons why patients with colorectal cancer often have diarrhea

Intestinal cancer is a common malignant disease of the digestive system, ranking fourth in the incidence of malignant tumors. Patients with intestinal cancer often suffer from diarrhea, which not only seriously affects the patient's normal life, but also causes certain damage to the patient's physical and mental health. Let's take a look at the reasons why patients with intestinal cancer often have diarrhea.

Intestinal environmental factors

For most patients with colorectal cancer, the intestinal environment changes after surgery, the number of some beneficial bacteria decreases, and the normal flora in the intestine that is sensitive to antibiotics is suppressed due to the use of antibiotics. As a result, the balance of the intestinal flora environment is broken, the flora is unbalanced, and diarrhea occurs.

Reasons for surgery

Intestinal cancer patients who need surgery may have a certain intestinal segment removed, which greatly reduces the intestinal mucosal contact area and intestinal content volume, resulting in increased stool water content, which may cause frequent diarrhea. If patients with low rectal cancer who require the anus to be preserved often experience diarrhea, it may be because the anal sphincter or pelvic floor nerves were accidentally damaged during surgery, causing anal sphincter dysfunction and diarrhea.

Dietary factors

Many family members consider that the patient is weak after surgery, so they feed the patient a lot of nutritious soups and food. In fact, the patient's gastrointestinal function has not yet fully recovered to normal, and many foods, especially greasy and difficult to digest foods, cannot be absorbed normally, and diarrhea is caused by indigestion.

Tips: How to relieve diarrhea in patients

1. Diet: After the anus is exhausted 3 days after surgery, give the patient liquid food, such as rice soup, millet porridge, etc.; gradually give semi-liquid food. The diet should be as light and mild as possible.

2. If the patient experiences diarrhea during chemotherapy, he or she should report it to the doctor and take medication under the doctor's guidance.
