Anal Itching

What Causes Anal Itching?

Anal itching can have various causes, ranging in severity from 'minor' to 'needs attention'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose anal itching, we could:
  • Research the topic
  • Find a doctor with the time
  • Use a diagnostic computer system.
The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "anal itching" as a symptom.  Here are eight possibilities:
  • Candida / Yeast
  • Blastocystosis
  • Food Allergies
  • Mineral Need
  • Hemorrhoids
  • Poor Digestion
  • Pinworms
  • Liver Congestion

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
frequent mucus in stools
history of vaginal yeast infection
weak appetite
cigarette smoke sensitivity
diminished perspiration
moderate epigastric pain
slightly oily/sticky stools
bloating caused by many foods
lactose intolerance
indoor allergies
frequent postprandial somnolence
slightly pale stools
... and more than 120 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of anal itching:
Cause Probability Status
Mineral Need 90% Confirm
Liver Congestion 30% Unlikely
Candida / Yeast 28% Unlikely
Hemorrhoids 3% Ruled out
Food Allergies 3% Ruled out
Pinworms 0% Ruled out
Poor Digestion 0% Ruled out
Blastocystosis 0% Ruled out
* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

If you indicate bowel problems, The Analyst™ will ask further questions including this one:
Does your anus itch?
Possible responses:
→ Never / very rarely / don't know
→ Occasionally - a few times a month
→ Often, mostly at night
→ Often, day and night
Based on your response to this question, which may indicate either anal itching or anal itching at night, The Analyst™ will consider possibilities such as:
Pinworm Infection

Itching around the anus, especially at night, is a common symptom of pinworm infestation.  Symptoms are caused by the female pinworm laying her eggs.  They are usually mild, with many infected people having no symptoms at all.
