Diarrhea is characterized by watery bowel movements for at least 3 times each day. During diarrhea, intestinal mucosal cells secrete excess water and electrolytes. If diarrhea cannot be controlled, dehydration, imbalance of sodium and potassium and insufficient nutrition will occur. Therefore, we must know how to control diarrhea.

Causes of cancer patients prone to diarrhea

• Tumor cells produce hormones that interfere with the normal absorption and peristalsis of the intestinal tract, or radiotherapy and chemotherapy cause damage and inflammation to the intestinal cells, so the intestine cannot absorb nutrients, water and electrolytes for blood circulation.
• The surface of the intestine becomes smooth, allowing the peristalsis to become faster for absorption, and damage to the intestine is often the cause of infections in the body.
• Excessive use of antibiotics can also lead to diarrhea, and severe diarrhea can sometimes disrupt the treatment of cancer.
