Blood in the Stool: Causes, When to Seek Help, and Natural Ways to Support Bowel Health

Finding blood in the stool (also called rectal bleeding) can be alarming. In many cases the cause is minor, such as irritation from constipation or haemorrhoids. However, rectal bleeding should always be taken seriously and investigated, especially if it persists.

Bleeding usually indicates that tissue somewhere in the digestive tract has become irritated, inflamed, or injured. A healthcare professional should assess persistent bleeding to determine the cause and rule out more serious conditions.

The Colour of Blood Can Indicate the Source

The colour and appearance of the blood can sometimes provide clues about where the bleeding is occurring.

Bright Red Blood

This type of bleeding often occurs with conditions such as haemorrhoids or small tears in the anal tissue. Bright red blood usually indicates bleeding from the lower digestive tract, including:

  • The anus
  • The rectum
  • The sigmoid colon

Dark Red Blood

Darker red blood may indicate bleeding slightly higher in the colon, such as the transverse colon.

Black or Tarry Stools

Black, sticky, or tar-like stools (called melena) may suggest bleeding in the upper digestive tract, such as the stomach or small intestine. This may be associated with conditions like:

  • Stomach ulcers
  • Gastrointestinal inflammation
  • Upper digestive tract bleeding
  • If stools are black or tarry, medical attention should be sought promptly.

Possible Causes of Blood in the Stool

There are many potential causes of rectal bleeding, ranging from mild to serious.

Common causes include:

  • Haemorrhoids (swollen veins in the rectum or anus)
  • Anal fissures (small tears in the anal tissue)
  • Constipation and straining during bowel movements
  • Inflammation of the bowel
  • Colon polyps
  • Digestive ulcers
  • Diverticulitis
  • Crohn’s disease
  • Bowel injury or trauma
  • Colorectal cancer

Because the causes vary widely, proper medical evaluation is important.

These tests help identify the exact source of bleeding. Healthcare professionals may recommend diagnostic tests such as:

  • Rectal examination
  • Anoscopy
  • Colonoscopy

Diet Tips to Support Bowel Health

Increase Dietary Fibre

Fibre helps promote regular bowel movements and reduces straining during defecation.

Good fibre sources include:

  • Whole grains
  • Fruits and vegetables
  • Legumes
  • Seeds

Gradually increasing fibre intake helps support healthy bowel function.

Stay Well Hydrated

Adequate hydration helps keep stools soft and easier to pass.

Aim for around 2 litres of water per day, depending on individual needs.

Start the Day with Lemon Water

Drinking warm water with fresh lemon juice in the morning is a traditional naturopathic practice believed to stimulate digestion and bowel motility.

While scientific evidence is limited, many people find it helpful for supporting regular bowel movements.

Eat More Fruits and Vegetables

Fresh produce provides fibre, antioxidants, and nutrients that support digestive health.

Fruits traditionally considered soothing for digestion include:

Vegetables such as beetroot and leafy greens may also support bowel function.

Lifestyle Habits That Support Bowel Health

Prevent Constipation

Constipation is a major contributor to rectal bleeding. Preventing constipation reduces strain and pressure on the rectal tissues.

Avoid Excess Straining

Straining during bowel movements increases pressure on the veins around the anus, contributing to haemorrhoids and tissue irritation.

Stay Physically Active

Regular physical activity helps stimulate natural bowel motility, encouraging regular elimination.

Support Digestive and Liver Function

The liver and digestive organs play important roles in metabolism, detoxification, and digestion.

Supporting overall digestive health may contribute to improved bowel function.
