Blood in the stool?
A few days ago, the doctor noticed that the stool was harder than usual, and there was blood when wiping afterward.
In recent days, there has also been blood on the tissue after bowel movements.
The blood is bright red but not mixed in with the stool; it is only on the outside.
The amount is about the size of a 50 NT dollar coin.
I checked online for symptoms related to colorectal cancer, and I’m wondering if this could be an injury or something else.
Besides the first hard stool that caused some pain, the subsequent ones have not been painful.
Would drinking more water help improve this? Thank you, doctor.

There are three common causes of rectal bleeding: 1.
Anal fissures or skin abrasions, characterized by a small amount of blood accompanied by a sharp pain at the site of the injury.
2.
Ruptured thrombosed hemorrhoids, which typically produce a slightly larger volume of blood, usually occurring after straining during bowel movements, and may be painless or cause mild discomfort.
3.
Gastrointestinal bleeding related to conditions such as polyps, ulcers, or tumors, which presents with darker blood and may be associated with changes in bowel habits or abdominal symptoms; this is less common in younger individuals.
Based on your situation, it seems more similar to the first cause.
It is advisable to increase your fluid intake and dietary fiber to prevent constipation.
If the bleeding persists, a medical evaluation is necessary.

When it comes to the presence of blood in stool, particularly when it appears as bright red blood on toilet paper after wiping, it can be concerning and warrants careful consideration. The symptoms you describe suggest that the blood is likely coming from the rectal area rather than being mixed with the stool itself, which can help narrow down potential causes.
One of the most common causes of bright red blood on toilet paper is hemorrhoids. Hemorrhoids are swollen veins in the lower rectum or anus that can cause discomfort, itching, and bleeding, especially during bowel movements. If the stool is hard, as you mentioned, it can lead to straining during defecation, which may exacerbate hemorrhoids and result in bleeding.
Another possible cause could be anal fissures, which are small tears in the lining of the anus that can occur due to passing hard stools. These fissures can be quite painful and often lead to bright red blood on the toilet paper or in the toilet bowl.
While these are the most common explanations, it is essential to consider other potential causes, especially if the bleeding persists or is accompanied by other symptoms such as abdominal pain, changes in bowel habits, or weight loss. Conditions such as diverticular disease, colorectal polyps, or even colorectal cancer can also lead to rectal bleeding, although these are less common in younger individuals without other risk factors.
To address your question about whether drinking more water can help, staying well-hydrated is indeed beneficial for overall digestive health. It can help soften stools, making them easier to pass and potentially reducing the risk of hemorrhoids and fissures. Additionally, incorporating a diet rich in fiber can also aid in preventing constipation and promoting regular bowel movements.
However, it is crucial to seek medical attention if you experience persistent bleeding, significant pain, or any other concerning symptoms. A healthcare professional can perform a thorough evaluation, which may include a physical examination, a review of your medical history, and possibly further diagnostic tests such as a colonoscopy if deemed necessary.
In summary, while the symptoms you describe may be due to common and less serious conditions like hemorrhoids or anal fissures, it is essential to monitor your symptoms closely. If the bleeding continues or worsens, or if you have any other concerning symptoms, please consult a healthcare provider for a proper diagnosis and treatment plan. Early intervention can help address any underlying issues and provide peace of mind.
