Rectal bleeding that comes and goes

At a glance

Rectal bleeding that appears, settles, and then returns is one of the most common patterns people experience. It is usually caused by hemorrhoids or fissures that flare and improve depending on stool consistency, diet, and other factors.

This intermittent pattern can create a particular kind of anxiety — the bleeding seems to go away, which provides relief, and then returns, which triggers worry all over again.

Common causes of intermittent bleeding

Hemorrhoids

The most common cause. Hemorrhoid bleeding typically correlates with:

  • Periods of constipation or harder stools
  • Straining
  • Dietary changes
  • Prolonged sitting
  • Stress

When these factors improve, the bleeding settles. When they return, so does the bleeding.

Anal fissure

Fissures can partially heal and then re-tear, creating episodes of bleeding separated by pain-free periods. This is common with chronic fissures that have not fully resolved.

Dietary and lifestyle factors

Changes in diet, hydration, activity level, and stress can all affect bowel function and cause intermittent bleeding without a significant underlying condition.

Why the pattern matters

The fact that bleeding comes and goes is actually useful information:

  • Bleeding that correlates with constipation or straining strongly suggests hemorrhoids or fissure
  • Bleeding that occurs independently of bowel habits may warrant more thorough investigation
  • Bleeding that is becoming more frequent or heavier over time should be assessed
  • Bleeding that is always in the same pattern (e.g., only with hard stools) is more likely benign than bleeding that is unpredictable

When to get it checked

Even benign intermittent bleeding should be assessed at least once to confirm the cause. Seek assessment if:

  • The pattern has been present for more than a few weeks
  • Episodes are becoming more frequent
  • The amount of blood is increasing
  • There are other symptoms — change in bowel habits, mucus, weight loss, pain
  • You are over 40 and have not had an assessment
  • The anxiety about the bleeding is affecting your quality of life

Managing the pattern

If the cause has been confirmed as hemorrhoids or fissure, managing the intermittent pattern involves:

  • Maintaining soft stools consistently — not just during flare-ups
  • Addressing constipation promptly when it begins
  • Adequate fibre and hydration as a daily habit, not a reactive measure
  • Monitoring for changes in the pattern that would warrant reassessment

The goal is to reduce the frequency and severity of flare-ups through consistent self-care, rather than reacting to each episode individually.

When to seek care

If you experience any of the following, seek urgent medical care:

  • Bleeding that becomes heavy or persistent
  • Bleeding with unexplained weight loss or change in bowel habits
  • Dark red or black stool at any point
  • Bleeding with dizziness, fatigue, or feeling faint
