If you’re experiencing persistent anal itching, you’re not alone. While it’s a rarely discussed issue, it’s actually quite common, especially among those with digestive problems like IBS.
Let’s break down the most common causes of anal itching, starting with the rarest and working our way up to the most likely culprits.
Less Common Causes of Anal Itching

1. Anal Cancer (Less than 0.5%)
While very rare, anal cancer can cause persistent itching. If your symptoms don’t improve after trying other treatments, see a doctor to rule this out.
2. Anal Fissures (Less than 0.5%)
Small tears in the anal lining can cause pain, bleeding, and itching. Your doctor can usually diagnose this easily during an exam.
3. Sexually Transmitted Infections (STDs)
If you engage in sexual activity that could expose you to STDs, infections like herpes, chlamydia, or gonorrhea could be a factor. Don’t be embarrassed to discuss this with your doctor.
4. Psoriasis or Dermatitis (About 2%)
Skin conditions like eczema and psoriasis can cause itching anywhere on the body, including the anal area. If you have a history of skin problems, this might be the culprit.

5. Hemorrhoids (5-10%)
Hemorrhoids are swollen veins in the rectum that can cause pain, bleeding, and intense itching. If your anal itching is accompanied by discomfort during bowel movements, hemorrhoids may be to blame.
6. Pinworms (5%)
Pinworms are tiny worms more common in children but can affect adults too. They lay eggs around the anus, causing intense nighttime itching. The good news? Pinworms are easily treated with medication.
The Most Likely Causes of Anal Itching
7. Candida Overgrowth (30%)
Candida, a type of yeast, is a very common cause of anal itching. It can overgrow in the gut, leading to IBS-like symptoms, bloating, diarrhea, and itching. If you’ve struggled with gut issues, frequent antibiotic use, or sugar cravings, Candida may be at the root of your problem.
8. Chronic Diarrhea or Constipation (55%)
Both diarrhea and constipation can lead to irritation, excessive wiping, and increased moisture, all of which contribute to anal itching.
Why Do IBS Sufferers Experience Anal Itching?
Since IBS is a leading cause of chronic diarrhea or constipation, it’s no surprise that many IBS patients struggle with anal itching. Additionally, people with IBS-D (diarrhea-predominant IBS) are more likely to have Candida overgrowth, which further worsens itching.
What Can You Do About Anal Itching?
✅ Step 1: Address Your Digestion
If you suffer from diarrhea or constipation, focus on:
✔ Balancing your gut bacteria
✔ Eliminating food triggers
✔ Improving gut motility
✅ Step 2: Treat Candida Overgrowth
Since Candida is a major cause of anal itching and gut issues, using a high-quality spore-based probiotic can rebalance your microbiome and reduce symptoms.
