Rectal Bleeding: Causes and When to Seek Help

Blood in the stool?

Hello, I experience pain in my anus when I have a bowel movement, and then there is blood, which is bright red.
What could this be? It has been three days, and my lifestyle is irregular; I often go to bed late.
Could this have an impact?

This situation likely indicates a higher possibility of hemorrhoidal bleeding.
As long as there is no further bleeding, it should not be a concern.
It is recommended to avoid constipation during this period and to shorten the time spent on bowel movements.
Maintaining a good daily routine is also important; try to avoid staying up late.
Warm sitz baths may help alleviate symptoms, and you can also purchase hemorrhoidal suppositories at the pharmacy for use.
It is best not to take stool softeners indiscriminately; at this age, increasing dietary fiber and hydration should be sufficient.
If bleeding persists, it is advisable to consult a physician for evaluation.

Rectal bleeding can be a concerning symptom, and it's important to understand its potential causes and when to seek medical help. The presence of bright red blood during bowel movements often indicates that the bleeding is coming from the lower gastrointestinal tract, particularly the rectum or anus. Here are some common causes of rectal bleeding:
1. Hemorrhoids: These are swollen veins in the rectal area that can become inflamed and bleed, especially during bowel movements. Hemorrhoids are a common cause of bright red blood in the stool and can be associated with pain, itching, or discomfort.

2. Anal Fissures: A tear in the lining of the anus, often caused by passing hard stools, can lead to sharp pain and bleeding during bowel movements. The blood is usually bright red and may be seen on the toilet paper or in the toilet bowl.

3. Diverticular Disease: Diverticula are small pouches that can form in the walls of the colon. If these pouches become inflamed or infected (diverticulitis), they can cause bleeding.

4. Colorectal Polyps or Cancer: While less common, polyps (growths on the colon lining) and colorectal cancer can also cause rectal bleeding. This is particularly concerning if the bleeding is persistent or accompanied by other symptoms such as weight loss, changes in bowel habits, or abdominal pain.

5. Gastrointestinal Infections: Certain infections can cause inflammation and bleeding in the gastrointestinal tract, leading to rectal bleeding.

Given that you have been experiencing this symptom for three days, it is advisable to seek medical attention, especially if the bleeding persists, increases in volume, or is accompanied by other symptoms such as severe pain, fever, or changes in bowel habits. A healthcare provider can perform a thorough evaluation, which may include a physical examination, a digital rectal exam, and possibly imaging studies or a colonoscopy to determine the exact cause of the bleeding.

Regarding your lifestyle, irregular sleep patterns and stress can contribute to gastrointestinal issues, including constipation, which may exacerbate conditions like hemorrhoids or anal fissures. Maintaining a regular sleep schedule, a balanced diet rich in fiber, and staying hydrated can help improve bowel health and reduce the risk of further complications.

In summary, while there are several potential causes for rectal bleeding, it is crucial to consult a healthcare professional for an accurate diagnosis and appropriate treatment. Early intervention can help manage any underlying conditions and prevent more serious complications.
