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
  • Poor Digestion
  • Liver Congestion
  • Food Allergies
  • Blastocystosis
  • Pinworms
  • Hemorrhoids
  • Mineral Need

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:
being a recovering alcoholic
reduced desire to eat breakfast
having a CFS diagnosis
coughing up white/yellow curds
vaginal yeast infections
major fatigue for 3-12 months
frequent meal-related bloating
loss of appetite
poor mental clarity
very frequent stools
stomach upset by taking vitamins
difficulty falling asleep
... 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
Poor Digestion 92% Confirm
Candida / Yeast 27% Unlikely
Pinworms 24% Unlikely
Liver Congestion 0% Ruled out
Blastocystosis 0% Ruled out
Hemorrhoids 0% Ruled out
Mineral Need 0% Ruled out
Food Allergies 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.
