Rectal Bleeding

I am a 50 year old male. I have a medical annually; always clear. My father is Type 2 Diabetic. My most recent FBG is 6.4. Follow-up test planned.
Having noticed bright rectal blood periodically, I had a screening colonoscopy recently; it was clear. I take 'baby' aspirin daily as recommendecd by my GP. Seems the bleeding follows additional aspirin ingestion ie: two tablets for a headache.
Last visit, my GP mentioned IBS. Is this possible? Could it be due to hemmoroids (hemorrhoids) / fissures although I have no pain or itching. Is this possible or could the colonsocopy have missed something more serious?

With a negative colonoscopy, it is unlikely that a polyp or cancer is causing the bleeding.  Hemorrhoids or fissures can be missed with colonoscopy - you may want to consider an anoscopy for further visualization.  It is possible that the colonoscopy may have missed something more serious, but it is unlikely.

IBS may be possible - although bleeding is not necessarily common.  Certainly the aspirin may cause any hemorrhoid or fissure to bleed.  You have to discuss with your physician the risk/benefit ratio of taking aspirin versus stopping it (i.e. the cardioprotective effects vs risk of GI bleed).  

If the bleeding is a concern, you may want to consider switching to Plavix, which may have a lesser bleeding risk.  

Followup with your personal physician is essential.

IBS, as a cause of bleeding is unlikely, especially without symptoms. It's very possible to have hemorrhoidal bleeding without symptoms. Having had a recent (depending on what you mean by "recent") colonoscopy would strongly relieve worry about other causes.  If you have problems with hard stools that require straining sometimes, you should increase fiber and liquid intake. If you haven't already, you should mention it to your doctor: a simple anoscopy might be all that's needed.

"Recent" colonoscopy was 12 months ago.

I was diagnosed with Crohn's about 7 years ago. Recently I began bleeding.  I started Entocort, didn't stop. Then I started prednisone 40mg. I stopped bleeding after about 10 days then I was taken down progressively to 10mg and then I started back bleeding. I was also gave hydrocortisone suppositories.  They caused discomfort so I was given Rowasa. I was also given Remicad. Well after staying on 10mg of steroids for 2 weeks I was taken down again.  Once on 5mg I started bleeding again.  So back up to 10mg of steroids. Then back down. I came off of prednisone for a week then I began to bleed yet again. I was started back on prednisone and given a second colonoscopy and then it was decided no Crohn's was present. I began to bleed again three weeks later. I went back to the doctor and he decides I have and anal fissure.  He gave me hydrocortisone (which my previous doctor had prescribed) so without telling him I used more Rowasa which had been used before since the hydrocortisone caused discomfort. I am still bleeding and it has been three weeks.  Is it an anal fissure or could it be something else?  I and really confused since I have been sick since July 03.  I have researched anal fissures and it says they cause pain during bowel movements, but I have no pain in my rectum at anytime.  I just bleed with blood clots coming out of my rectum.  Blood surrounds the stool (not sure if mixed with stool) and blood is totally covering the tissue. Is there something I am missing, should I get a new GI doctor (already on second one)? I don't understand what could be wrong since I have had a colonoscopy in Aug. 03 and Dec. 03 and in Dec. "nothing" was found yet I continue to bleed with no rectal discomfort.

I have been taking medications that cause severe constipation. As a result I have been using fleet liquid glycerin suppositories. After a while using them, I have developed light Rectal Bleeding on occasion. The blood color is dark so I know it is old, the stool is normal color, and I have no pain. My age is 38....I am thinking Internal Hemorrhoids?.....any ideas or thoughts would be appreciated. Thanks
