Blood in Stool: Is It Hemorrhoids or Something Else? - Internal Medicine

I'm very scared?


Hello doctor, I have been experiencing some difficulty with bowel movements lately.
It has been over a week since my last bowel movement.
After drinking vinegar and eating apples, I finally felt the urge to go.
However, when I did, I noticed bright red blood on the stool, which seems to be adhering to it, although the stool itself is soft.
Could this be hemorrhoids, or is it just a normal occurrence due to not having a bowel movement for so long? Additionally, I had a bike accident where I hit the handlebars near my stomach due to an emergency stop.
I had an X-ray at that time, and the doctor said there was nothing unusual.
Could the current rectal bleeding be related to that impact? If there were any injuries or damage to my stomach, what symptoms would I expect to see? What should I do to take care of my stomach now?

Based on your age and the symptoms you described, the likelihood of blood in your stool being caused by constipation is higher, rather than being a result of malignant tumors such as colorectal cancer.
Additionally, the abdominal impact from riding a motorcycle a few days ago is unlikely to have caused the issues you described, and it is not considered gastric bleeding.
I recommend that you engage in regular exercise, drink plenty of water, and consume more fruits and vegetables, as these measures should help improve your condition.
If you still have concerns, you may consider undergoing a rectal and anal examination.

When it comes to the presence of blood in stool, it is essential to understand the potential causes and implications of this symptom. Based on your description, you have experienced a week of constipation followed by the passage of soft stool that is accompanied by bright red blood. This situation raises several considerations regarding the possible causes of the bleeding.

Firstly, the bright red blood that adheres to the stool is often indicative of bleeding from the lower gastrointestinal tract, particularly the rectum or anus. One of the most common causes of such bleeding is hemorrhoids, which are swollen veins in the rectal area that can become inflamed and bleed, especially during bowel movements. Given that you mentioned having difficulty with bowel movements, it is plausible that straining during defecation could have exacerbated or caused hemorrhoids, leading to the observed bleeding.

Another possibility is anal fissures, which are small tears in the lining of the anus that can occur due to passing hard or large stools. These can also result in bright red blood during bowel movements and are often accompanied by pain.

Regarding your concern about the impact of a previous injury from a motorcycle accident, it is less likely that this would be the direct cause of the blood in your stool unless there was significant trauma to the abdominal area that resulted in internal bleeding. Since you have already undergone an X-ray that showed no abnormalities, it is reassuring that there is no immediate concern regarding major internal injuries. However, if you experience symptoms such as severe abdominal pain, vomiting, or changes in bowel habits, it would be prudent to seek further medical evaluation.

In terms of gastrointestinal health, maintaining a balanced diet rich in fiber can help prevent constipation and promote regular bowel movements. Foods such as fruits, vegetables, whole grains, and adequate hydration are essential. If you find that you are frequently constipated, consider incorporating more fiber into your diet and staying well-hydrated. Over-the-counter stool softeners or fiber supplements may also be beneficial, but it is advisable to consult with a healthcare professional before starting any new medications or supplements.

If the bleeding persists, worsens, or is accompanied by other concerning symptoms (such as significant abdominal pain, weight loss, or changes in bowel habits), it is crucial to seek medical attention. A healthcare provider may recommend further diagnostic tests, such as a colonoscopy, to evaluate the source of the bleeding and rule out any serious conditions.

In summary, while hemorrhoids or anal fissures are likely culprits for the bright red blood in your stool, it is essential to monitor your symptoms closely. Maintaining a healthy diet and lifestyle can significantly contribute to your gastrointestinal health. If you have ongoing concerns or if your symptoms change, do not hesitate to reach out to a healthcare professional for further evaluation and guidance.
