Dry stool is usually not bowel cancer. After the occurrence of bowel cancer, the patient’s bowel habit will be changed, manifesting as increased frequency of bowel movement or even diarrhea, and the nature of bowel movement will be changed, manifesting as unshaped bowel movement and blood in the stools, or even mucous blood stools and pus and blood stools, so after the occurrence of bowel cancer, the bowel movement will not be dry, in other words, if there is dryness in the stools, it has nothing to do with the bowel cancer in general. In other words, if there is dry stool, there is no relationship with bowel cancer. When there is dry stool, it may be related to the low dietary fiber eaten by the patient, and also related to the low water intake, etc. The patient should not eat spicy and stimulating food, and can eat fresh vegetables and fruits, and need to drink more water, and can take oral medication for laxative and laxative treatment if necessary.
