Can perimenopause cause rectal bleeding?

Hello,

Welcome to icliniq.com.

I understand your concern.

Since you have had multiple scans, an MRI (magnetic resonance imaging), a sigmoidoscopy, and a colonoscopy without any significant findings, it is reassuring that nothing serious has been detected. Given your history of hemorrhoids and vaginal atrophy, there are a few possible reasons for bleeding from the back passage during your periods. Hormonal changes during your cycle can increase blood flow to pelvic veins, making hemorrhoids more likely to bleed.

Straining or constipation can further worsen this. Additionally, perimenopause causes estrogen fluctuations, which can lead to increased fragility in blood vessels and tissues, including those in the rectal area. Vaginal atrophy, which leads to thinning and dryness of vaginal tissues, may also irritate the surrounding rectal area, making it more prone to minor bleeding. Although your previous tests have not indicated endometriosis, some women with deep infiltrating endometriosis experience rectal bleeding during their periods due to endometrial tissue affecting the bowel.

If the bleeding worsens or occurs outside your period, further evaluation may be needed. Managing hemorrhoids with fiber supplements, hydration, sitz baths, or medicated creams may help reduce symptoms. Vaginal estrogen therapy, if not contraindicated, could improve vaginal atrophy and reduce irritation around the area. If symptoms persist or worsen, consulting a gastroenterologist or gynecologist for further assessment would be advisable. If the bleeding remains light and occurs only during your period, it is likely related to hemorrhoids or hormonal changes, but monitoring any new symptoms is essential.

I hope this helps.

Let me know if you need further guidance.

Thank you.
