Rectal Bleeding: Is It Hemorrhoids or Anal Fissures? - Surgery

Bowel issues


Hello Doctor, this morning I had a bowel movement that was normal.
However, later I experienced some discomfort in my abdomen, which felt crampy and rolling, and then I had diarrhea.
After the diarrhea, when I wiped for the fourth or fifth time, I noticed very tiny red spots on the toilet paper (the stool itself was yellow).
Could this possibly be a sign of anal fissure or hemorrhoids? Thank you for your response, Doctor.

When it comes to rectal bleeding, distinguishing between hemorrhoids and anal fissures is crucial for appropriate treatment and management. Both conditions can cause bleeding during bowel movements, but they have different underlying causes and treatment approaches.

Hemorrhoids are swollen veins in the lower rectum or anus, similar to varicose veins. They can be internal (inside the rectum) or external (under the skin around the anus). Symptoms often include painless bleeding during bowel movements, itching, and discomfort. The blood is usually bright red and may appear on the toilet paper or in the toilet bowl. Hemorrhoids can be caused by increased pressure in the lower rectum due to factors such as straining during bowel movements, prolonged sitting, pregnancy, or obesity.

Anal fissures, on the other hand, are small tears in the lining of the anus. They are often associated with painful bowel movements, and the pain can be severe, sometimes lasting for hours after the bowel movement. Bleeding from an anal fissure is typically bright red and may be accompanied by sharp pain during and after bowel movements. Fissures are commonly caused by passing hard or large stools, chronic diarrhea, or anal trauma.

In your case, the presence of small red blood spots on the toilet paper after experiencing diarrhea could suggest either condition. Given that you mentioned the stool was yellow and that you had abdominal discomfort, it is possible that the irritation from frequent wiping after diarrhea could have caused a minor anal fissure. However, if the bleeding continues or worsens, or if you experience significant pain, it is essential to consult a healthcare professional for a proper diagnosis.

Management and Treatment:
1. For Hemorrhoids:
- Dietary Changes: Increase fiber intake to soften stools and reduce straining. This can include fruits, vegetables, whole grains, and plenty of fluids.

- Over-the-Counter Treatments: Creams or ointments containing hydrocortisone can help reduce inflammation and discomfort.

- Sitz Baths: Soaking in warm water can relieve pain and promote healing.

- Medical Procedures: If conservative treatments fail, procedures such as rubber band ligation or sclerotherapy may be considered.

2. For Anal Fissures:
- Dietary Adjustments: Similar to hemorrhoids, a high-fiber diet is crucial to prevent constipation and straining.

- Topical Treatments: Numbing creams or ointments can help alleviate pain. In some cases, prescription medications that relax the anal sphincter may be used.

- Sitz Baths: Regular warm baths can promote healing and relieve discomfort.

- Surgery: If fissures do not heal with conservative measures, surgical options may be necessary.

When to Seek Medical Attention:
- If you experience persistent bleeding, significant pain, or if the bleeding is accompanied by other symptoms such as fever, changes in bowel habits, or weight loss, it is essential to seek medical evaluation. A healthcare provider can perform a physical examination and may recommend further tests, such as a colonoscopy, to rule out other conditions.

In conclusion, while your symptoms could indicate either hemorrhoids or anal fissures, the best course of action is to monitor your symptoms closely and consult a healthcare professional for an accurate diagnosis and tailored treatment plan. Early intervention can help prevent complications and ensure a quicker recovery.
