What Causes Bright Red Blood in Stool?

The causes of blood in stool cannot be generalized and should be comprehensively analyzed and judged based on factors such as age of onset, the manner, amount, color of the blood, and the presence of symptoms such as pain. Typically, it may be related to conditions such as rectal cancer and hemorrhoids. Firstly, there are various causes of blood in stool, and this symptom can be associated with various gastrointestinal diseases. The specific diagnosis should be made through comprehensive analysis based on factors such as age of onset, the manner, amount, color of the blood, and the presence of symptoms like pain. If the stool appears tarry or black, the bleeding is likely to be located in the upper digestive tract, suggesting a higher possibility of bleeding from the stomach or duodenum. If the blood is purplish red, mixed with mucus, and accompanied by a foul odor, the possibility of intestinal cancer, especially rectal cancer, should be considered. Generally, if the blood in stool is bright red and appears as droplets on the surface of the stool, the bleeding is most likely to occur at or near the anus, which may indicate hemorrhoids. However, it is worth noting that in cases of massive upper gastrointestinal bleeding, the blood can also appear bright red due to the short residence time in the digestive tract. To confirm the diagnosis, medical examination becomes a crucial step.

Secondly, regarding prevention measures for blood in stool, it is important to maintain a good lifestyle with a balance between work and rest, avoiding excessive fatigue, and keeping the body healthy. Additionally, it is crucial to maintain a healthy diet with regular meals, reduced intake of spicy and greasy foods such as chili, alcohol, and smoking, and increased consumption of vegetables, fruits, and other foods rich in fiber and vitamins to maintain soft and smooth bowel movements.
