What happened to diarrhea and hematochezia?

Diarrhea and blood in the stool may be caused by diseases such as intestinal tuberculosis, inflammatory bowel disease, and colorectal cancer.

1. Intestinal tuberculosis

Intestinal tuberculosis is caused by infection with Mycobacterium tuberculosis. Patients can form ulcers due to inflammatory stimulation of the intestinal mucosa, leading to diarrhea, blood in the stool, and abdominal pain.

2. Inflammatory bowel disease

Inflammatory bowel disease is a non-specific inflammatory disease of the intestine. Patients may experience symptoms such as diarrhea and blood in the stool due to long-term inflammatory stimulation of the intestinal mucosa.

3. Colorectal cancer Patients with colorectal cancer may

experience bleeding and blood in the stool due to local infiltration of the intestinal mucosa by cancer cells, and diarrhea may occur due to traction of the intestinal tract.
