Anorectal Symptom

Rectal Bleeding.

Rectal bleeding is alarming. It is also extremely common — and in the vast majority of cases, the cause is benign: hemorrhoids, anal fissures, or another treatable condition. Most patients with rectal bleeding are not facing cancer.

That said, rectal bleeding is also the most important early warning sign of colorectal cancer. It deserves evaluation. Not panic — evaluation. We are going to be direct about what to look for, when to be seen, and what we'll do once you are here.

Dr. Johnson provides a careful, thorough evaluation for patients with rectal bleeding

If you've noticed any of these, it's worth a conversation.

Most patients tell us they assumed the symptom was minor — or just something they would have to live with. Neither is usually true.

  • Bright-red blood on the toilet paper or in the bowl
  • Blood mixed in with stool
  • Dark or maroon-colored blood
  • Black, tarry stools (this needs prompt evaluation)
  • Bleeding with pain (often a fissure)
  • Bleeding without pain (often a hemorrhoid — but always worth checking)

Types & subtypes

Bright Red on Paper

The most common pattern. Usually originates very close to the anal opening — most often an internal hemorrhoid or an anal fissure. Almost always benign, almost always treatable.

Bright Red Mixed with Stool

Originates from slightly higher in the rectum. Usually still hemorrhoidal in origin but warrants a careful evaluation to be certain.

Dark or Maroon Blood

Originates higher in the colon. Warrants prompt evaluation and usually colonoscopy. Not within PHII's primary scope — we will coordinate the referral if it is what you need.

Black, Tarry Stool

Suggests bleeding from the upper GI tract. Requires urgent evaluation, often in an emergency setting. This is not something to manage with an outpatient appointment.

Common causes & risk factors

  • Internal hemorrhoids (the most common cause by a wide margin)
  • Anal fissures
  • Diverticular disease
  • Inflammatory bowel disease
  • Polyps or, rarely, colorectal cancer
  • Anticoagulant medication can amplify bleeding from any of the above

Treatment Approach

Non-surgical first. Always.

Most patients with rectal bleeding improve significantly with behavioral, physical, and minimally invasive treatments — long before surgery enters the conversation. Here is the full toolbox, in the order we typically work through it.

Non-surgical options

Targeted physical exam
A careful, gentle anorectal examination — often the only diagnostic step needed for typical hemorrhoidal bleeding. Performed with full explanation and consent.
Anoscopy
An in-office, brief look at the lower rectum and anal canal. No prep, no sedation, no driver.
Hemorrhoid banding when indicated
If bleeding is from internal hemorrhoids, the banding procedure addresses both the bleeding and the underlying hemorrhoid.
Coordinated screening
When the picture suggests higher-up bleeding, or when colorectal cancer screening is overdue, we coordinate the appropriate referral. We will not punt; we will hand the referral off completely.

A Patient Story

I was terrified. I had been bleeding for six weeks and assumed the worst. Dr. Johnson saw me within four days, diagnosed an internal hemorrhoid in the first ten minutes, and explained the screening timeline I should be on regardless. The relief was indescribable.

Frequently Asked

Rectal Bleeding: the questions patients ask Dr. Johnson.

Is rectal bleeding always serious?

Almost never the worst-case scenario, but always worth evaluating. The two most common causes — internal hemorrhoids and anal fissures — are entirely benign and entirely treatable. The reason we still want to see you is that the rare causes that aren't benign are far more treatable when caught early.

— Lisa L. Johnson, M.D., U.R.P.S.

When should I be seen urgently?

Heavy bleeding, lightheadedness, black or tarry stools, or a change in bowel habits accompanying the bleeding warrant prompt — often emergency — evaluation. Persistent bleeding for more than a few days, even if mild, also warrants an appointment within the next week or two.

— Lisa L. Johnson, M.D., U.R.P.S.

Do I need a colonoscopy?

Depends on the pattern of bleeding, your age, your family history, and whether you are due for routine screening. Many patients with classic hemorrhoidal bleeding do not need a colonoscopy specifically for that bleeding — but they should still be up to date on routine colorectal cancer screening. We will tell you honestly which category you are in.

— Lisa L. Johnson, M.D., U.R.P.S.

Could this be cancer?

It is the question on every patient's mind, so I want to answer it straight. In most patients — particularly under 45, particularly with classic bright-red, painless or activity-related bleeding — the answer is overwhelmingly likely to be no. For older patients, patients with risk factors, or patients with concerning bleeding patterns, we evaluate carefully and coordinate the right next step. We will not minimize, and we will not catastrophize.

— Lisa L. Johnson, M.D., U.R.P.S.

What if I'm on a blood thinner?

Blood thinners amplify bleeding from any source — including hemorrhoids that might otherwise be silent. We still want to see you, we still want to identify the source, and we will coordinate with your prescribing physician about any medication considerations around treatment.

— Lisa L. Johnson, M.D., U.R.P.S.

Ready when you are.

A thorough, unhurried evaluation with Dr. Johnson. You will leave with a written plan — and clarity on what rectal bleeding is doing in your body, and what to do about it.
