Rectal Bleeding: Can Sexual Activity Trigger Internal Hemorrhoids? - Surgery

Hemorrhoidal bleeding caused by sexual intercourse?


Hello, doctor.
Last month, I experienced a sudden episode of heavy rectal bleeding and was taken to the hospital for treatment.
After undergoing a colonoscopy, I was diagnosed with mild internal hemorrhoids and anal swelling.
I would like to know if it is really possible for internal hemorrhoids to cause such a significant amount of bleeding suddenly? Additionally, after improving my diet and lifestyle, I have had almost no bleeding symptoms, but after sexual intercourse, I suddenly feel gas movement in my abdomen and need to go to the bathroom, resulting in heavy rectal bleeding again (it is all fresh blood).
Can I still exercise after being diagnosed with internal hemorrhoids?

In young individuals, significant bleeding is mostly due to hemorrhoids.
If dietary and lifestyle modifications do not stop the bleeding, medication should be used.
If medication is ineffective, further examination or invasive treatment may be necessary.
There are no restrictions on exercise for internal hemorrhoids; however, activities such as weight training that increase anal pressure should be temporarily avoided.

Rectal bleeding can be a concerning symptom, and understanding its causes is essential for effective management. In your case, the diagnosis of mild internal hemorrhoids (or "internal痔") and anal swelling provides a clear starting point for understanding your symptoms. Internal hemorrhoids can indeed lead to significant bleeding, especially if they become inflamed or thrombosed. It is not uncommon for individuals with internal hemorrhoids to experience sudden and substantial bleeding, particularly during bowel movements or after activities that increase abdominal pressure, such as sexual activity.

When engaging in sexual activity, especially if it involves positions or movements that put pressure on the abdominal area, it can lead to increased intra-abdominal pressure. This pressure can exacerbate existing hemorrhoids, potentially causing them to bleed. Additionally, if there is any straining during sexual activity or if the anal area is manipulated, it could further irritate the hemorrhoids, leading to bleeding.

Your observation that bleeding occurs after sexual activity suggests that the physical exertion or pressure from the activity might be triggering your symptoms. It’s important to note that while sexual activity itself does not directly cause hemorrhoids, it can aggravate pre-existing conditions, leading to bleeding.

Regarding your question about exercise, it is generally advisable for individuals with hemorrhoids to engage in regular, moderate exercise. Exercise can help improve bowel function and reduce constipation, which is a significant contributor to hemorrhoid formation and exacerbation. However, high-impact activities or exercises that involve heavy lifting or straining should be approached with caution, as they can increase abdominal pressure and potentially worsen your symptoms.

In terms of dietary and lifestyle changes, continuing to maintain a high-fiber diet, staying hydrated, and avoiding straining during bowel movements can significantly help manage your symptoms. If you find that certain activities, including sexual activity, consistently lead to bleeding, it may be beneficial to discuss this with your healthcare provider. They can provide tailored advice and may suggest treatments such as topical medications, rubber band ligation, or other interventions if necessary.

If you experience significant or recurrent bleeding, it is crucial to seek medical attention. While mild internal hemorrhoids can often be managed conservatively, more severe cases may require medical intervention. Additionally, any new or worsening symptoms should be evaluated to rule out other potential causes of rectal bleeding, such as anal fissures, diverticular disease, or other gastrointestinal issues.

In summary, while sexual activity can trigger bleeding in individuals with internal hemorrhoids, it is essential to manage your overall health through diet, exercise, and regular medical check-ups. If you have concerns about your symptoms or if they persist, do not hesitate to consult with your healthcare provider for further evaluation and management.
