Rectal Bleeding: Hemorrhoids or Anal Fissures? - Surgery

Rectal bleeding


Hello doctor, I would like to ask about a situation I've been experiencing for about a week.
After having a bowel movement, I sometimes notice blood dripping from my anus, but usually, it stops as soon as I leave the toilet.
I've also observed that sometimes just sitting on the toilet causes me to see fresh blood on the toilet paper when I wipe.
It feels like the pressure from sitting on the toilet is causing the bleeding.
Could this be bleeding from hemorrhoids or an anal fissure? What should I do for care and management moving forward?

Anal fissures are typically associated with pain during or after bowel movements; internal hemorrhoids may cause more significant bleeding but are not necessarily painful.
During the acute phase, it is advisable to take warm sitz baths, reduce the time spent in the bathroom, avoid alcohol and irritating foods, and use hemorrhoid creams or suppositories to alleviate symptoms.
If bleeding persists, a visit to a gastroenterologist or a colorectal specialist is necessary for evaluation.

More Info


Rectal bleeding can be a concerning symptom, and it is essential to understand the potential causes and appropriate management strategies. Based on your description, it sounds like you may be experiencing either hemorrhoids or anal fissures, both of which are common conditions that can lead to rectal bleeding.

Hemorrhoids are swollen veins in the lower rectum or anus, similar to varicose veins. They can be classified as internal or external. Internal hemorrhoids are usually painless and may cause bleeding during bowel movements, often presenting as bright red blood on the toilet paper or in the toilet bowl. External hemorrhoids, on the other hand, can be painful and may cause discomfort, especially when sitting or during bowel movements.

Anal fissures, on the other hand, are small tears in the lining of the anus. They are often associated with pain during and after bowel movements, and the pain can be severe. Bleeding from an anal fissure typically appears as bright red blood on the toilet paper or on the stool itself. Fissures are often caused by passing hard stools or straining during bowel movements.

Given that you mentioned the bleeding occurs after bowel movements and sometimes when you sit on the toilet, it is possible that you are experiencing one of these conditions. The fact that the bleeding stops shortly after leaving the toilet suggests that it may be related to the pressure exerted during bowel movements or sitting.


Management and Care
1. Dietary Changes: To prevent further episodes of bleeding, it is crucial to maintain a diet high in fiber. This can help soften the stool and make bowel movements easier. Foods rich in fiber include fruits, vegetables, whole grains, and legumes. Additionally, staying well-hydrated by drinking plenty of water can also aid in preventing constipation.

2. Over-the-Counter Treatments: For hemorrhoids, topical treatments such as hydrocortisone creams or witch hazel pads can provide relief from itching and discomfort. For anal fissures, topical anesthetics or medications that promote healing, such as nitroglycerin ointment or calcium channel blockers, may be recommended by your healthcare provider.

3. Sitz Baths: Taking warm sitz baths can help soothe the area and promote healing. Soaking the anal area in warm water for about 10-15 minutes several times a day can provide relief from pain and discomfort.

4. Avoid Straining: It is essential to avoid straining during bowel movements. If you feel the urge to go, try to respond promptly rather than holding it in, as this can lead to harder stools and increased straining.

5. When to Seek Medical Attention: If the bleeding persists, increases in volume, or is accompanied by severe pain, changes in bowel habits, or any other concerning symptoms (such as fever or significant weight loss), it is crucial to seek medical attention. A healthcare provider may perform a physical examination and possibly recommend further investigations, such as a colonoscopy, to rule out other potential causes of rectal bleeding.

6. Follow-Up Care: Regular follow-up with your healthcare provider is essential to monitor your symptoms and adjust treatment as necessary. If you have been diagnosed with hemorrhoids or anal fissures, your provider can guide you on the best management strategies and when to consider more invasive treatments if conservative measures fail.

In summary, while hemorrhoids and anal fissures are common causes of rectal bleeding, proper management through dietary changes, topical treatments, and lifestyle modifications can significantly alleviate symptoms. However, it is essential to consult with a healthcare provider for an accurate diagnosis and tailored treatment plan.
